BBC News - UN hits back at climate sceptics amid e-mails row

Delegates watch the opening of the UN Climate ...Image by oxfam international via Flickr

Things are "hotting up" in the Global warming arena. You'll know that a bunch of so-called scientists have been cobbling together various facts and figures in a most unscrupulous concoction of half truths and lies.

Their presentation of scientific fact was no more than a manipulation of their data, an attempt to dupe everyone into believing that things are very much worse as regards global warming than the real facts show. Emailgate goes on and the UN gets involved.

For shame - Professors of Non Truth.

Now they're hitting back after being found out.........Read below for even more distortion.

Are Skeptics allowed in?

Global-Warming Skeptics Raise A Storm In New York

"Human contribution is small, probably not zero, and it's small compared to these other factors which we cannot change," said one conference participant.
March 10, 2009

By Nikola KrastevNEW YORK --

These are tough times to be a skeptic about global warming. Two years ago, an international United Nations panel concluded with near certainty that human activity plays a role in the planet's rising temperatures. And now, the new U.S. administration has vowed to spearhead international efforts to reduce greenhouse-gas emissions.But more than 600 people gathered in New York City this week at the International Conference on Climate Change say they are up to the challenge.

Joseph Bast, president of the Heartland Institute, which organized the conference, argues that the extent and causes of global warming are far from proven.


The goal of the gathering, he tells RFE/RL, is to provide a forum to challenge people like former U.S. Vice President Al Gore with a healthy dose of skepticism.

"We think we have a great story to tell that more and more prominent scientists are coming out saying global warming is not a crisis, that the question of what causes it and how extensive it's going to be are wide open in the scientific community," Bast said."And that message is not effectively reaching enough people," he adds. "So, by holding an event like this we hope that we can get the attention of more people and eventually have an effect on public policy.

"There is a special urgency at this year's gathering. Governments around the world are working on plans to further tax greenhouse-gas emissions, while U.S. President Barack Obama has proposed to roll greenhouse-gas emissions back to their 1990s levels. 'Vehicle For Government Intervention'But many conference participants say those efforts are misguided. Those who acknowledge global warming is happening say the Earth is going through a natural, periodic cycle, with industrial activity contributing very little to the process.


By the ideology which uses or misuses it -- it has gradually turned into the most efficient vehicle for advocating extensive government intervention into all fields of life and for suppressing human freedom and economic prosperity.

The Heartland Institute bills itself as a free-market think tank. Until 2006, the Chicago-based group received money from oil giant Exxon Mobil, although that has now stopped. The institute has not shied away from taking up other controversial causes. For example, it also seeks to decrease high taxes on cigarettes and curbs on smokers.The keynote speech was delivered by Czech President Vaclav Klaus, who has become well-known for his opinions on the issue. Speaking to students at Columbia University a day later, he reaffirmed his vocal opposition to the concept that global warming is man-made.

"The problem is not global warming," Klaus said. "By the ideology which uses or misuses it -- it has gradually turned into the most efficient vehicle for advocating extensive government intervention into all fields of life and for suppressing human freedom and economic prosperity."

'An Overstated Truth'?

Al Gore has won worldwide acclaim for his environmental activities and especially for raising awareness about climate change with the film "An Inconvenient Truth." In 2007 he won the Nobel Peace Prize along with the UN panel for his climate-change-awareness activities.Bast of the Heartland Institute argues that although Gore is the most prominent spokesman for the man-made climate-change cause, his arguments lie "way outside the mainstream scientific community."

"Very few qualified scientists would say that Al Gore and what he says in his film is accurate. He grossly overstates the possibility of sea-level rise for example," Bast says."There's simply no peer-reviewed scientific literature that would justify predictions of a 20-foot [6-meter] rise in sea level, and yet that's very prominent in his film."Dr. Howard MacCabee, an oncologist in California and a conference participant, says that even very liberal estimates show that industrial pollution by itself has negligible or little effect on global warming.

"Human contribution is small, probably not zero, and it's small compared to these other factors which we cannot change. We cannot change the sun, we cannot change [the sun's] multidecadal oscillations, we can't change ocean currents, we can't stop El Nino," MacCabee says."El Nino was the biggest spike on the temperature for the past 40 years. That was in 1998 and the hottest year in our recent history was the 1998, the year of El Nino, which has nothing to do with CO2 [carbon dioxide]," he adds.

For now, the conference participants seem to be losing the argument.A recent opinion poll in the United States showed that 58 percent of respondents believe climate change is at least partly caused by humans. But another poll, by the Pew Research Center, indicates that in these times of economic turmoil, addressing climate change is not a top priority for many Americans.

Allergies and climate change

Allergies rising with climate change, pollution
Kent Spencer, The ProvincePublished: Wednesday, March 26, 2008
To some, spring flowers are just pollen. But to thousands of allergy sufferers, they're appallin'.
Dr. Ross Chang says allergies are on the rise worldwide due to increased pollution, drought and climate change.
"This season has been very busy in the Lower Mainland," said Chang, president of the B.C. Society of Allergy and Immunology. "The number of people with allergies seems to be increasing every year."


Recent studies on the problem include one from United Nations climate experts and another from Dr. Paul Epstein of Harvard Medical School.
Strong links were found between greenhouse gases and growth of pollinating plant pests. Dust has also increased in areas of drought.
Epstein said more allergies will strain the health system and burden the economy, which will suffer from worker absences due to ill health.
Chang believes this spring's hot and cold spells have caused plants' reproductive systems to go into overdrive for short periods.
"Pollen levels aren't higher. They're coming in spikes. It seems to be caused by more weather extremes," he said. "Before, plants would pollinate in an orderly fashion."
Earlier this year, a weather channel reported trees in Vancouver were emitting 400 grains of pollen per cubic metre, five times higher than normal. Moderate pollen emissions are between 21 and 80.
"Some days, it seems like a horrible season," Chang said. "How bad it will be depends on the weather. It's kind of like planning a wedding and not knowing if it will rain."
Pollen is one of several tiny particles that trigger allergies. Others include dust, mould, air pollution, and dog and cat hair.
"Allergies are not simply coming from trees and grass in the summertime," said Chang.
He said the body's immune system "seeks to destroy" the particles because it believes they are carrying disease, which they aren't.
"They're just irritants," he said.
The condition results in watery and swollen eyes, a runny nose, itchy throat and shortness of breath.
"If you're working at a desk, fluid from your nose drips on to the paper.
"It can be hard to function," he said.
Treatments include taking antihistamines, prescription nasal sprays and eye drops, allergy tests and injections. Chang said one-third of the Lower Mainland's two-million-plus residents have allergies.
Christina Pedersen, 27, of Coquitlam said the effects can be terrible.
"I break out in hives," she said. "My eyes swell up so badly there are times when I can't work. I would be in a hideous mess without injections. I think it has been getting worse over the years."

The Tipping Point.......

Scientists identify 'tipping points' of climate change

By Steve Connor, Science EditorTuesday, 5 February 2008


Nine ways in which the Earth could be tipped into a potentially dangerous state that could last for many centuries have been identified by scientists investigating how quickly global warming could run out of control.
A major international investigation by dozens of leading climate scientists has found that the "tipping points" for all nine scenarios – such as the melting of the Arctic sea ice or the disappearance of the Amazon rainforest – could occur within the next 100 years.
The scientists warn that climate change is likely to result in sudden and dramatic changes to some of the major geophysical elements of the Earth if global average temperatures continue to rise as a result of the predicted increase in emissions of man-made greenhouse gases.
Most and probably all of the nine scenarios are likely to be irreversible on a human timescale once they pass a certain threshold of change, and the widespread effects of the transition to the new state will be felt for generations to come, the scientists said.
"Society may be lulled into a false sense of security by smooth projections of global change. Our synthesis of present knowledge suggests that a variety of tipping elements could reach their critical point within this century under anthropogenic [man-made] climate change," they report in the journal Proceedings of the National Academy of Sciences.
The study came out of a 2005 meeting of 36 leading climate scientists who drew on the expertise of a further 52 specialists. It is believed to be the first time that scientists have attempted to assess the risks of what they have termed "tipping elements" in the Earth's climate system.
The nine elements range from the melting of polar ice sheets to the collapse of the Indian and West African monsoons. The effects of the changes could be equally varied, from a dramatic rise in sea levels that flood coastal regions to widespread crop failures and famine. Some of the tipping points may be close at hand, such as the point at which the disappearance of the summer sea ice in the Arctic becomes inevitable, whereas others, such as the tipping point for the destruction of northern boreal forests, may take several more decades to be reached.
While scenarios such as the collapse of the Indian monsoon could occur within a few years, others, such as the melting of the Greenland ice cap or the West Antarctic ice sheet, may take several centuries to complete. "Our findings suggest that a variety of tipping elements could reach their critical point in this century under human-induced climate change," said Professor Timothy Lenton, of the University of East Anglia, who led the study.
A tipping point is defined as the point where a small increase in temperature or other change in the climate could trigger a disproportionately larger change in the future. Although there are many potential tipping points that could occur this century, it is still possible to avoid them with cuts in greenhouse gases, said Professor Lenton.
He added: "But we should be prepared to adapt ... and to design an early-warning system that alerts us to them in time."
Irreversible changes
* Arctic sea ice: some scientists believe that the tipping point for the total loss of summer sea ice is imminent.
* Greenland ice sheet: total melting could take 300 years or more but the tipping point that could see irreversible change might occur within 50 years.
* West Antarctic ice sheet: scientists believe it could unexpectedly collapse if it slips into the sea at its warming edges.
* Gulf Stream: few scientists believe it could be switched off completely this century but its collapse is a possibility.
* El Niño: the southern Pacific current may be affected by warmer seas, resulting in far-reaching climate change.
* Indian monsoon: relies on temperature difference between land and sea, which could be tipped off-balance by pollutants that cause localised cooling.
* West African monsoon: in the past it has changed, causing the greening of the Sahara, but in the future it could cause droughts.
* Amazon rainforest: a warmer world and further deforestation may cause a collapse of the rain supporting this ecosystem.
* Boreal forests: cold-adapted trees of Siberia and Canada are dying as temperatures rise.

Breaking news today ~ Cold Weather hits China again........

180,000 stranded in southern China as cold weather returns: report
8 hours ago ~ 18th February 2008


BEIJING (AFP) — Freezing weather has again swept through southern China, leaving 180,000 people stranded and causing power outages, just as the region was recovering from the last cold snap, state press said Monday.
The latest cold weather has taken a severe toll in mountainous Yunnan province, where heavy snowfalls since Thursday have caused huge problems, the China Daily said.
Eighty percent of the two million residents in Qujing city remain without electricity due to the combined impacts of the most recent cold snap and the ferocious weather that first hit southern China in early January.
The snowfalls over the past few days have also blocked 14,000 kilometres (8,700 miles) of roads in Yunnan, a prime reason behind the large number of people stranded, the China Daily said, citing provincial transport authorities.
In Qujing, the second biggest city in Yunnan, six highways have been closed while 42 bus routes have been cancelled, according to the paper.

Yunnan was one of the areas hit hard by the cold snap in January and early February, which was the worst winter weather seen in the region in more than 50 years.

The weather led to the deaths of at least 107 people and caused more than 15 billion dollars in economic losses, according to official figures released last week.

Ice and snowfalls crippled power and transport networks, with authorities admitting they were unprepared for the ferocity of the weather.

How Dry We Are
A Question No One Wants to Raise About Drought

By Tom Engelhardt

Georgia's on my mind. Atlanta, Georgia. It's a city in trouble in a state in trouble in a region in trouble. Water trouble. Trouble big enough that the state government's moving fast. Just this week, backed up by a choir singing "Amazing Grace," accompanied by three protestant ministers, and 20 demonstrators from the Atlanta Freethought Society, Georgia's Baptist Governor Sonny Perdue led a crowd of hundreds in prayers for rain. "We've come together here," he said, "simply for one reason and one reason only: To very reverently and respectfully pray up a storm." It seems, however, that the Almighty -- He "who can and will make a difference" -- was otherwise occupied and the regional drought continued to threaten Atlanta, a metropolis of 5 million people (and growing fast), with the possibility that it might run out of water in as little as 80 days or as much as a year, if the rains don't come.
Here's a little summary of the situation today:
Water rationing has hit the capital. Car washing and lawn watering are prohibited within city limits. Harvests in the region have dropped by 15-30%. By the end of summer, local reservoirs and dams were holding 5% of their capacity.
Oops, that's not Atlanta, or even the southeastern U.S. That's Ankara, Turkey, hit by a fierce drought and high temperatures that also have had southern and southwestern Europe in their grip.
Sorry, let's try that again. Imagine this scenario:
Over the last decade, 15-20% decreases in precipitation have been recorded. These water losses have been accompanied by record temperatures and increasing wildfires in areas where populations have been growing rapidly. A fierce drought has settled in -- of the hundred-year variety. Lawns can be watered but just for a few hours a day (and only by bucket); four-minute showers are the max allowed. Car washes are gone, though you can clean absolutely essential car windows and mirrors by hand.
Sound familiar? As it happens, that's not the American southeast either; that's a description of what's come to be called "The Big Dry" -- the unprecedented drought that has swept huge parts of Australia, the worst in at least a century on an already notoriously dry continent, but also part of the world's breadbasket, where crops are now failing regularly and farms closing down.
In fact, on my way along the parched path toward Atlanta, Georgia, I found myself taking any number of drought-stricken detours. There's Moldova. (If you're like me, odds are you don't even know where that small, former Soviet republic falls on a map.) Like much of southern Europe, it experienced baking temperatures this summer, exceptionally low precipitation, sometimes far less than 50% of expected rainfall, failing crops and farms, and spreading wildfires. (The same was true, to one degree or another, of Albania, Bulgaria, Croatia, Macedonia, and -- with its 100-year record scorching of Biblical proportions -- Greece which lost 10% of its forest cover in a month-long fiery apocalypse, leaving "large tracts of countryside…. at risk of depopulation.")
Or how about Morocco, across the Mediterranean, which experienced 50% less rainfall than normal? Or the Canary Islands, those Spanish vacation spots in the Atlantic Ocean known to millions of visitors for their year-around mild climate which, this summer, morphed into 104 degree days, strong winds, and fierce wildfires. Eighty-six thousand acres were burnt to a crisp, engulfing some of the islands in flames and smoke that drove out thousands of tourists?
Or what about Mexico's Tehuacán Valley, where, thousands of years ago, corn was first domesticated as an agricultural crop. Even today, asking for "un Tehuacán" in a restaurant in Mexico still means getting the best bottled mineral water in the country. Unfortunately, the area hasn't had a good rain since 2003, and the ensuing drought conditions have made subsistence farming next to impossible, sending desperate locals northwards and across the border as illegal immigrants -- some into southern California, itself just swept by monstrous Santa Ana-driven wildfires, fanned by prolonged drought conditions and fed tinder by new communities built deep into the wild lands where the fires gestate. And Tehuacán is but one disaster zone in a growing Mexican catastrophe. As Mike Davis has written, "Abandoned ranchitos and near-ghost towns throughout Coahuila, Chihuahua and Sonora testify to the relentless succession of dry years -- beginning in the 1980s but assuming truly catastrophic intensity in the late 1990s -- that has pushed hundreds of thousands of poor rural people toward the sweatshops of Ciudad Juárez and the barrios of Los Angeles."
According to the How Dry I Am Chart of "livability expert" Bert Sperling, four cities in Southern California, not parched Atlanta, top the national drought ratings: Los Angeles, San Diego, Oxnard, and Riverside. In addition, Pasadena has had the dubious honor, through September, of experiencing its driest year in history.
Resource Wars in the Homeland
"Resource wars" are things that happen elsewhere. We don't usually think of our country as water poor or imagine that "resource wars" might be applied as a description to various state and local governments in the southwest, southeast, or upper Midwest now fighting tooth and nail for previously shared water. And yet, "war" may not be a bad metaphor for what's on the horizon. According to the National Climate Data Center, federal officials have declared 43% of the contiguous U.S. to be in "moderate to extreme drought." Already, Sonny Perdue of Georgia is embroiled in an ever more bitter conflict -- a "water war," as the headlines say -- with the governors of Florida and Alabama, as well as the Army Corps of Engineers, over the flow of water into and out of the Atlanta area.
He's hardly alone. After all, the Southwest is in the grips of what, according to Davis, some climatologists are terming a "'mega-drought,' even the 'worst in 500 years.'" More shockingly, he writes, such conditions may actually represent the region's new "normal weather." The upper Midwest is also in rainfall-shortage mode, with water levels at all the Great Lakes dropping unnervingly. The water level of Lake Superior, for instance, has fallen to the "lowest point on record for this time of year." (Notice, by the way, how many "records" are being set nationally and globally in these drought years; how many places are already beginning to push beyond history, which means beyond any reference point we have.)
And then there's the southeast, 26% of which, according to the National Weather Service, is in a state of "exceptional" drought, its most extreme category, and 78% of which is "drought-affected." We're talking here about a region normally considered rich in water resources setting a bevy of records for dryness. It has been the driest year on record for North Carolina and Tennessee, for instance, while 18 months of blue skies have led Georgia to break every historical record, whether measured by "the percentage of moisture in the soil, the flow rate of rivers, [or] inches of rain."
Atlanta is hardly the only city or town in the region with a dwindling water supply. According to David Bracken of Raleigh's News & Observer, "17 North Carolina water systems, including Raleigh and Durham, have 100 or fewer days of water supply remaining before they reach the dregs." Rock Spring, South Carolina, "has been without water for a month. Farmers are hauling water by pickup truck to keep their cattle alive." The same is true for the tiny town of Orme, Tennessee, where the mayor turns on the water for only three hours a day.
And then, there's Atlanta, its metropolitan area "watered" mainly by a 1950s man-made reservoir, Lake Lanier, which, in dramatic photos, is turning into baked mud. Already with a population of five million and known for its uncontrolled growth (as well as lack of water planning), the city is expected to house another two million inhabitants by 2030. And yet, depending on which article you read, Atlanta will essentially run out of water by New Year's eve, in 80 days, in 120 days, or, according to the Army Corps of Engineers -- which seems to find this reassuring -- in 375 days, if the drought continues (as it may well do).
Okay, so let's try again:
Across the region, fountains sit "bone dry"; in small towns, "full-soak" baptisms have been stopped; car washes and laundromats are cutting hours or shutting down. Golf courses have resorted to watering only tees and greens. Campfires, stoves, and grills are banned in some national parks. The boats have left Lake Lanier and the metal detectors have arrived.
This is the verdant southeastern United States, which, thanks in part to a developing La Nina effect in the Pacific Ocean, now faces the likelihood of a drier than ever winter. And, to put this in context, keep in mind that 2007 "to date has been the warmest on record for land [and]… the seventh warmest year so far over the oceans, working out to the fourth warmest overall worldwide." Oh, and up in the Arctic sea, the ice pack reached its lowest level this September since satellite measurements were begun in 1979.
And Then?
And then, there's that question which has been nagging at me ever since this story first caught my attention in early October as it headed out of the regional press and slowly made its way toward the top of the nightly TV news and the front-pages of national newspapers; it's the question I've been waiting patiently for some environmental reporter(s) somewhere in the mainstream media to address; the question that seems to me so obvious I find it hard to believe everyone isn't thinking about it; the one you would automatically want to have answered -- or at least gnawed on by thoughtful, expert reporters and knowledgeable pundits. Every day for the last month or more I've waited, as each piece on Atlanta ends at more or less the same point -- with the dire possibility that the city's water will soon be gone -- as though hitting a brick wall.
Not that there hasn't been some fine reportage -- on the extremity of the situation, the overbuilding and overpopulating of the metropolitan region, the utter heedlessness that went with it, and the resource wars that have since engulfed it. Still, I've Googled around, read scores of pieces on the subject, and they all -- even the one whose first paragraph asked, "What if Atlanta's faucets really do go dry?" -- seem to end just where my question begins. It's as if, in each piece, the reporter had reached the edge of some precipice down which no one cares to look, lest we all go over.
Based on the record of the last seven years, we can take it for granted that the Bush administration hasn't the slightest desire to glance down; that no one in FEMA who matters has given the situation the thought it deserves; and that, on this subject, as on so many others, top administration officials are just hoping to make it to January 2009 without too many more scar marks. But, if not the federal government, shouldn't somebody be asking? Shouldn't somebody check out what's actually down there?
So let me ask it this way: And then?
And then what exactly can we expect? If the southeastern drought is already off the charts in Georgia, then, whether it's 80 days or 800 days, isn't there a possibility that Atlanta may one day in the not-so-distant future be without water? And what then?
Okay, they're trucking water into waterless Orme, Tennessee, but the town's mayor, Tony Reames, put the matter well, worrying about Atlanta. "We can survive. We're 145 people but you've got 4.5 million there. What are they going to do?"
What indeed? Has water ever been trucked in to so many people before? And what about industry including, in the case of Atlanta, Coca Cola, which is, after all, a business based on water? What about restaurants that need to wash their plates or doctors in hospitals who need to wash their hands?
Let's face it, with water, you're down to the basics. And if, as some say, we've passed the point not of "peak oil," but of "peak water" (and cheap water) on significant parts of the planet… well, what then?
I mean, I'm hardly an expert on this, but what exactly are we talking about here? Someday in the reasonably near future could Atlanta, or Phoenix, which in winter 2005-2006, went 143 days without a bit of rain, or Las Vegas become a Katrina minus the storm? Are we talking here about a new trail of tears? What exactly would happen to the poor of Atlanta? To Atlanta itself?
Certainly, you've seen the articles about what global warming might do in the future to fragile or low-lying areas of the world. Such pieces usually mention the possibility of enormous migrations of the poor and desperate. But we don't usually think about that in the "homeland." Maybe we should.
Or maybe, for all I know, if the drought continues, parts of the region will burn to a frizzle first, à la parts of southern California, before they can even experience the complete loss of water? Will we have hundred-year fire records in the South, without a Santa Ana wind in sight? And what then?
Mass Migrations?
Okay, excuse a terrible, even tasteless, sports analogy, but think of this as a major bowl game, and they've sent one of the water boys -- me -- to man the press booth. I mean, please. Why am I the one asking this? Where's the media's first team?
In my own admittedly limited search of the mainstream, I found only one vivid, thoughtful recent piece on this subject: "The Future Is Drying Up," by Jon Gertner, written for the New York Times Magazine. It focused on the southwestern drought and began to explore some of the "and thens," as in this brief passage on Colorado in which Gertner quotes Roger Pulwarty, a "highly regarded climatologist" at the National Oceanic and Atmospheric Administration:
"The worst outcome…. would be mass migrations out of the region, along with bitter interstate court battles over the dwindling water supplies. But well before that, if too much water is siphoned from agriculture, farm towns and ranch towns will wither. Meanwhile, Colorado's largest industry, tourism, might collapse if river flows became a trickle during summertime."
Mass migrations, exfiltrations…. Stop a sec and take in that possibility and what exactly it might mean. After all, we do have some small idea, having, in recent years, lost one American city, New Orleans, at least temporarily.
Or consider another "and then" prediction: What if the prolonged drought in the southwest turns out, as Mike Davis wrote in the Nation magazine, to be "on the scale of the medieval catastrophes that contributed to the notorious collapse of the complex Anasazi societies at Chaco Canyon and Mesa Verde during the twelfth century"?
What if, indeed.
I'm not simply being apocalyptic here. I'm just asking. It's not even that I expect answers. I'd just like to see a crew of folks with the necessary skills explore the "and then" question for the rest of us. Try to connect a few dots, or tell us if they don't connect, or just explain where the dots really are.
As the World Burns
Okay, since I'm griping on the subject, let me toss in another complaint. As this piece has indicated, the southeastern drought, unlike the famed cheese of childhood song, does not exactly stand alone. Such conditions, often involving record or near record temperatures, and record or near record wildfires, can be observed at numerous places across the planet. So why is it that, except at relatively obscure websites, you can hardly find a mainstream piece that mentions more than one drought at a time?
An honorable exception would be a recent Seattle Times column by Neal Peirce that brought together the southwestern and southeastern droughts, as well as the Western "flame zone," where "mega-fires" are increasingly the norm, in the context of global warming, in order to consider our seemingly willful "myopia about the future."
But you'd be hard-pressed to find many pieces in our major newspapers (or on the TV news) that put all (or even a number) of the extreme drought spots on the global map together in order to ask a simple question (even if its answer may prove complex indeed): Do they have anything in common? And if so, what? And if so, what then?
To find even tentative answers to such questions you have to leave the mainstream. Amy Goodman of Democracy Now!, for example, interviewed paleontologist and author of The Weather Makers: The History and Future Impact of Climate Change, Tim Flannery recently on the topic of a "world on fire." Flannery offered the following observation:
"It's not just the Southeast of the United States. Europe has had its great droughts and water shortages. Australia is in the grip of a drought that's almost unbelievable in its ferocity. Again, this is a global picture. We're just getting much less usable water than we did a decade or two or three decades ago. It's a sort of thing again that the climate models are predicting. In terms of the floods, again we see the same thing. You know, a warmer atmosphere is just a more energetic atmosphere. So if you ask me about a single flood event or a single fire event, it's really hard to make the connection, but take the bigger picture and you can see very clearly what's happening."
I know answers to the "and then" question are not easy or necessarily simple. But if drought -- or call it "desertification" -- becomes more widespread, more common in heavily populated parts of the globe already bursting at the seams (and with more people arriving daily), if whole regions no longer have the necessary water, how many trails of tears, how many of those mass migrations or civilizational collapses are possible? How much burning and suffering and misery are we likely to experience? And what then?
These are questions I can't answer; that the Bush administration is guaranteed to be desperately unwilling and unprepared to face; and that, as yet, the media has largely refused to consider in a serious way. And if the media can't face this and begin to connect some dots, why shouldn't Americans be in denial, too?
It's not that no one is thinking about, or doing work on, drought. I know that scientists have been asking the "and then" questions (or perhaps far more relevant ones that I can't even formulate); that somewhere people have been exploring, studying, writing about them. But how am I to find out?
Of course, all of us can wander the Internet; we can visit the National Oceanic and Atmospheric Administration, which has just set up a new website to help encourage drought coverage; we can drop in at blogs like RealClimate.org and ClimateProgress.org, which make a habit of keeping up with, or ahead of, such stories; or even, for instance, the Georgia Drought website of the University of Georgia's College of Agricultural and Environmental Sciences; or we can keep an eye on a new organization of journalists (well covered recently on the NPR show "On the Media"), Circle of Blue, who are planning to concentrate on water issues. But, believe me, even when you get to some of these sites, you may find yourself in an unknown landscape with no obvious water holes in view and no guides to lead you there.
In the meantime, there may be no trail of tears out of Atlanta; there may even be rain in the city's near future for all any of us know; but it's clear enough that, globally and possibly nationally, tragedy awaits. It's time to call in the first team to ask some questions.
Honestly, I don't demand answers. Just a little investigation, some thought, and a glimpse or two over that precipice as the world turns.... and bakes and burns.

Extremes

The year of extremes
Climate changes already apparent; Northeast should be prepared for its turn

By Richard A. Rehberg, Ph.D.

Extreme weather has made the Weather Channel a source of unending fascination this year.

In North America, Texas and Oklahoma experienced record rainfall. Searing heat, severe drought, and intense brush and forest fires plagued the West and the Southwest. Georgia, Alabama, the Carolinas, and Virginia experienced prolonged drought. Atlanta, Ga., worries whether it will have drinking water beyond the New Year. Record 100-year floods plagued parts of the American Midwest. A tornado struck Brooklyn, New York. Severe thunderstorms shut sections of the New York City subway system. Intense hurricanes swept the Caribbean and Central America, and floods have just inundated much of the Mexican state of Chiapas. Fortunately, in the Southern Tier, we enjoyed a rather pleasant summer.

Europe and Asia have experienced extreme weather as well. May, June and July were the wettest in England and Wales since records began in 1766. Rainfall in Germany was the highest in May since observations began in 1901. Southeastern Europe suffered record-breaking heat during June and July. Heavy rains ravaged areas of Southern China, bringing hardship to almost 14 million people, with more than 120 deaths. Long-term drought threatens to cut farm output in Australia by up to 20 percent and economic growth by 1 to 2 percent.

Weather is what we experience today, this month, and this year. No single weather event -- for example, Hurricane Katrina -- can be attributed to climate change. However, when we average weather over longer periods of time, say over 30 years or more, we have what scientists call climate. Actual weather measurements, including temperature and precipitation extend back 100 or more years. Cores drilled from Greenland and the Antarctic as well as from the ocean beds enable scientists to infer the Earth's climate 300,000 to 400,000 years into the geological past. By studying climate over these periods, scientists are able to understand how our climate is changing.

Climate change over the planet

That the Earth's climate is changing is regarded as "unequivocal" by the Intergovernmental Panel on Climate Change. Since the 1800s, the average temperature of the planet has risen by almost 2 degrees Fahrenheit. More than half of that increase has occurred since the late 1970s. Carbon dioxide (CO2) is the greenhouse gas responsible for about 50 percent of observed human-caused climate change. Since the Industrial Revolution began in the early 1800s, atmospheric concentrations of CO2 have risen from 280 parts per million (ppm) to over 385 ppm today. Methane, nitrous oxide and other trace gases also contribute. Greenhouse gases are the "trapdoors" of our atmosphere: open to the shorter wavelengths of the sun's incoming energy, energy that warms the surface of the Earth, but closed to the longer wavelengths (infrared) of that energy that is reradiated to our atmosphere. Once trapped within the atmosphere, that energy warms our planet. The more fossil fuel we burn the more greenhouse gases we emit and the warmer the planet becomes. Absent substantial reductions in our burning of fossil fuels and forests, atmospheric CO2 is projected to rise by 2050 to 450 to 550 ppm and by 2100 to 900 to 1,000 ppm. During this period, average global temperatures are projected to increase by between 4 and 10 degrees Fahrenheit.

Other evidence confirms the changing of Earth's climate:

* Ocean temperatures to depths of 10,000 feet are rising, indicating that the oceans have absorbed more than 80 percent of the heat added to the climate system;

* Ice sheet losses are accelerating both in Greenland and the Antarctic;

* Arctic temperatures have risen at almost twice the global rate in the past 50 years;

* Atmospheric water vapor is increasing (warmer air holds more moisture);

* Global precipitation is increasing;

* Periods of intense rainfall are becoming more frequent;

* Severe droughts occur more often;

* Cold days and nights are decreasing; warm days and nights are increasing, spring arrives almost a month earlier and fall a month later;

* Heat waves are rising in frequency and intensity; and

* Hurricanes in the Atlantic and typhoons in the Pacific are becoming more intense.

Climate change here in the Northeast

We in the Northeast should not expect our weather good fortune of this past year to continue. Our region already has been affected by climate change. Since 1970, the Northeast has been warming at a rate of nearly 0.5 degree Fahrenheit per decade with winter temperatures rising even more rapidly at a rate of about 1.3 F per decade from 1970 to 2000.

Indeed, "Confronting Climate Change in the U.S. Northeast," a report released in July of this year by the Northeast Climate Impacts Assessments (NECIA) team notes that warming over the past 40 years or so, our region has been marked by:

* More frequent days with temperatures above 90 F;

* Longer growing seasons;

* Less winter precipitation falling as snow and more as rain;

* Reduced snow pack and increased snow density;

* Earlier ice breakups on rivers and lakes;

* Earlier spring snowmelt resulting in earlier river and stream peak flows.

Moreover, because of the heat already stored in the oceans and the heat trapping gases now in the atmosphere, NECIA projects that by mid-century and beyond temperatures in the Northeast will rise another 2.5 to 4 F in winter and 1.5 F to 3.5 F in summer.

If United States, China, and India continue their "high emissions" of carbon and other greenhouse gases, then we may anticipate a "starkly" different climate future. Under this "high emissions" scenario, the NECIA projects for the Northeastern United States that by 2100 (when our children and grandchildren shall have inherited our future):

* Winters in the Northeast will warm by 8 to 12 F and summers by 6 to 14 F above historic levels;

* The snow season in northern New York, Vermont, New Hampshire and Maine will be cut in half;

* Northeastern cities will average 20 or more days of 100 F-plus temperatures compared with only a few such days at present;

* Short-term droughts (one to three months) could occur as often as once each summer in the Catskills and the Adirondacks and across New England;

* Extreme coastal flooding that now occurs only once a century could strike New York City on average once a decade;

* Hemlock stands that shade and cool Northeast streams could be lost to pests that thrive in warmer weather with the result that many steams will lose their shade, thus raising their temperatures and threatening native brook trout and other favorite species;

* As forest habitat changes, migratory songbirds such as the Baltimore oriole, American goldfinch and song sparrow may become less abundant;

* Parts of the Northeast may become unsuitable for growing certain varieties of apples, blueberries and cranberries. Milk production will be subject to decline significantly in the warmer months.

Immediate and substantial action by the world's major economies, including the United States, India and China, could and would avoid Northeast climate change of the magnitude we have just described. NOTE: With a lower-emissions scenario, projected changes might be only half the magnitude of those described for the higher-emissions scenario.

In California, both Governor Arnold Schwarzenegger and the Legislature, informed and inspired in part by examples set by the European Union, have committed the state to reduce its greenhouse gas emissions to pre-1990 levels by the year 2020. They have set an even more ambitious goal of an 80 percent reduction below 1990 levels by 2050. New York state is considering similar ambitious reductions. Almost all scientists believe that such dramatic reductions must be achieved by all of humanity if we are to avoid potentially catastrophic climate change.

Which leaves us with this critical question: if California, New York, and a number of other states, along with much of Europe, recognize the severity the challenge posed by climate change and appear to be acting rather decisively to address that challenge, why is there so little evidence of bold and decisive leadership in Washington?
