With the world losing the battle against global warming so far, experts are warning that humans need to follow nature’s example: Adapt or die. That means elevating buildings, making taller and stronger dams and seawalls, rerouting water systems, restricting certain developments, changing farming practices and ultimately moving people, plants and animals out of harm’s way.
Adapting to rising seas and higher temperatures is expected to be a big topic at the U.N. climate-change talks in Copenhagen next week, along with the projected cost – hundreds of billions of dollars, much of it going to countries that cannot afford to do it themselves. That adaptation will be a major focus is remarkable in itself.
Until the past couple of years, experts avoided talking about adjusting to global warming for fear of sounding fatalistic or causing countries to back off efforts to reduce emissions. …
Some biologists point to how nature has handled the changing climate. The rare Adonis blue butterfly of Britain looked as if it was going to disappear because it couldn’t fly far and global warming was making its habitat unbearable. To biologists’ surprise, it evolved longer thoraxes and wings, allowing it to fly farther to cooler locales.
“Society needs to be changing as much as wildlife is changing,” said Texas A&M biologist Camille Parmesan, an expert on how species change with global warming.
Change too fast to adapt?
One difficulty is that climate change is happening rapidly.
“Adaptation will be particularly challenging because the rate of change is escalating and is moving outside the range to which society has adapted in the past” when more natural climate changes happened, U.S. National Oceanic and Atmospheric Administration chief Jane Lubchenco, a marine biologist, told Congress on Wednesday.
Cities, states and countries are scrambling to adapt or are at least talking about it and setting aside money for it. Some examples:
President Barack Obama and Congress are talking about $1.2 billion a year from the U.S. for international climate aid, which includes adaptation. …
The World Bank estimates adaptation costs will total $75 billion to $100 billion a year over the next 40 years. The International Institute for Environment and Development, a London think tank, says that number is too low.
It may even be $200 billion a year or $300 billion a year, said Chris Hope, a business school professor at the University of Cambridge and part of the IIED study. Nevertheless, Hope said failing to adapt would be even more expensive — perhaps $6 trillion a year on average over the next 200 years. Adaptation could cut that by about $2 trillion a year, he said. …
‘Planned relocation’ ahead?
As for helping plants and animals, British climate scientist Martin Parry said the world will have to create a triage system to figure out which living things can be saved, which can’t and are effectively goners, and which don’t need immediate help. …
Some islands, such as the Maldives, and some coastal cities will not be able to survive rising seas no matter what protections are put in place, said Saleemel Huq, a senior fellow at IIED who runs an adaptation center in Bangladesh.
In those cases, he said, the world will need “planned relocation” of people and cities.
Parmesan said people are going to have to realize that “some areas are not going to be good enough to live in in the next 100 years.”

LONDON – E-mails stolen from climate scientists show they stonewalled skeptics and discussed hiding data – but the messages don’t support claims that the science of global warming was faked, according to an exhaustive review by The Associated Press.
The 1,073 e-mails examined by the AP show that scientists harbored private doubts, however slight and fleeting, even as they told the world they were certain about climate change. However, the exchanges don’t undercut the vast body of evidence showing the world is warming because of man-made greenhouse gas emissions.
The scientists were keenly aware of how their work would be viewed and used, and, just like politicians, went to great pains to shape their message. …
Some e-mails expressed doubts about the quality of individual temperature records or why models and data didn’t quite match. Part of this is the normal give-and-take of research, but skeptics challenged how reliable certain data was. …
The AP studied all the e-mails for context, with five reporters reading and rereading them – about 1 million words in total. …

WASHINGTON — A Commerce Department investigation has found no evidence of wrongdoing on the part of U.S. climate researchers whose e-mails were leaked in the debate over global climate change.
The report Thursday from the department’s inspector general is the latest to exonerate climate scientists whose communications with the Climate Research Unit at England’s University of East Anglia were stolen and made public in 2009. The department reviewed all 1,073 leaked e-mails, but focused on 289 that involved National Oceanic and Atmospheric Administration scientists.
Mary Glackin, NOAA’s deputy undersecretary for operations, said she welcomed the report since “none of the investigations have found any evidence to question the ethics of our scientists or raise doubts about NOAA’s understanding of climate change science.”
Climate change skeptics have sought to characterize some of the e-mails as indicating scientists failed to follow proper procedures or altered data. Investigations in both England and by the National Research Council and Pennsylvania State University in the United States have also concluded that there was no indication of scientific impropriety.
The new report did question the handling of some freedom of information requests by NOAA and asked the agency to review the circumstances under which funds were transferred to the British researchers. Glackin said the money was used for workshops that assisted the governments of Cambodia, Laos and Vietnam in improving their climate forecasting work. …

WASHINGTON – The 2000-2009 decade was the warmest on record, easily surpassing the previous hottest decade — the 1990s — researchers said Tuesday in a report providing fresh evidence that the planet may be warming at a potentially disastrous rate.
In 2009, global surface temperatures were 1.01 degree above average, which tied the year for the fifth warmest year on record, the National Climatic Data Center said.
And that helped push the 2000-2009 decade to 0.96 degree above normal, which the agency said “shattered” the 1990s record value of 0.65 degree above normal.
The warmest year on record was 2005 at 1.11 degrees above normal.
The findings follow years of gradually rising global temperatures which atmospheric scientists attribute to the warming effect of gases released into the air by human activities, including burning fossil fuels. …
Concerns about the effects of a warmer climate include rising sea levels and the potential spread of tropical diseases, changes in hurricane patterns, increased drought in some areas, disruption of crop growth and wildlife patterns, and loss of species unable to adapt. …

Is the record-shattering heatwave that has been blamed for the deaths of thousands in Russia somehow related to the devastating flooding in Pakistan?
Are these disasters happening more frequently — and are they a result of global warming? …
Muscovites will long remember the summer of 2010 as the hottest and most extreme weather summer in the city’s long history. The all-time temperature record was set, and re-set, five different times during a two-week span from late July to early August. In that period the temperature climbed above 30 degrees Celsius (87 degrees Fahrenheit) for 29 consecutive days (and still counting).
In addition to the extreme heat, which reached up to 39 degrees Celsius (102 degrees Fahrenheit) on multiple days in a city that averages an August high of 22 degrees Celsius (72 degrees Fahrenheit), the capital was shrouded in a thick layer of smoke from area wildfires.
The combination of extreme heat and lack of rainfall left western Russia vulnerable to wildfires, which burned out of control southeast of Moscow.
Nearly 4,000 kilometers (2,485 miles) away in Pakistan, monsoon rains fell with an intensity that had never before been observed.
Peshawar, a city in northern Pakistan 140 km (87 miles) west of the capital Islamabad, received six times the monthly average rainfall in only 24 hours.
Heavy rain has continued to occur throughout Pakistan since the initial heavy downpour on July 29, and the flooding has impacted an estimated 14 million people, killing over 1,300 at time of writing. …
As we continually stress, one extreme weather event, or even a series of weather events, is not caused by global warming or climate change. Weather extremes such as floods or heat waves happen every year, all over the globe.
Many climate scientists believe, however, that these events will become more common, as the Earth warms because of global warming. Others will point to more distinct and shorter-scale cycles such as El Nino and La Nina, which commonly lead to extremes in weather around the globe.
So, while we can tie many of these global weather disasters together around a common meteorological trigger, we cannot say for certain if climate change is helping to pull that trigger, or perhaps loading the gun more frequently. …
U.N. agency also says 2010 could be single warmest year on record

CANCUN, Mexico — This last decade was the warmest since temperature records began in 1850, the U.N.’s World Meteorological Organization said Thursday in a review issued on the sidelines of U.N. talks in Mexico that are seeking ways to rein in global warming.
“Recent warming has been especially strong in Africa, parts of Asia, and parts of the Arctic,” it said in a statement. “The Saharan/Arabian, East African, Central Asian and Greenland/Arctic Canada sub-regions have all had 2001-10 temperatures 1.2 to 1.4 degrees C (about 2 degrees Fahrenheit) above the long-term average, and 0.7 degrees C to 0.9 degrees C (about 1.5 F) warmer than any previous decade.”
While no single weather event can be traced to human activity and greenhouse gases, WMO Secretary-General Michel said natural variation cannot explain the decade-long record. “If you don’t take the human emission into account you cannot reproduce what you observe,” he said.
Moreover, Jarraud said there is a “significant possibility 2010 could be the warmest” year on record, surpassing 1998 and 2005.
The British Met Office — one of the three main groups that compiled the data that was then peer-reviewed — said 2010 was “more likely than not” the warmest year.
A final review in early 2011 will determine 2010′s place, though there is still a chance 2010 will be just below 1998 and 2005 if December cools, the WMO stated.
The WMO said that land and sea surface temperatures so far in 2010 were 0.55 degrees C (1 F) above a 1961-1990 average of 14 degrees C (57.2 F).

WASHINGTON — Last year tied for the warmest globally since records began, the U.S. agency that tracks temperatures said on Wednesday, capping a decade of record high temperatures and raising concerns about more storms and floods related to climate change.
Combined global land and ocean temperatures in 2010 were 1.12 degrees Fahrenheit above the 20th century average, tying the record set in 2005, the National Climatic Data Center, an office of the National Oceanic and Atmospheric Administration, said in a release.
“These results show that the climate is continuing to show the influence of greenhouse gases, it’s showing evidence of warming,” David Easterling, the chief of the scientific services division at the NCDC, told reporters.
Other facets pointed out by NOAA:
Despite last year’s frigid temperatures and snow storms in the United States and Europe many places, such as Russia and Pakistan, suffered from heat waves and floods that wrecked crops and helping lead to record global food prices.
It’s not possible to link one weather event directly to global warming, but the trend of rising temperatures since 2000 increases the possibility that such events will happen, Easterling said. …

St. Cloud Times
April 3, 2012
March 2012 was the warmest on record in St. Cloud [Minnesota], setting numerous daily records along the way, according to the National Weather Service.
Monthly records for average and mean temperature were set and the average high was the second warmest in history. The marks toppled records set in 1910.
In addition, St. Cloud recorded seven cooling degrees days, counted when the temperture exceeds 65 degrees. St. Cloud had not previously recorded a cooling degree day in March, according to the National Weather Service.
“It is pretty extreme to get that kind of heat this early in the year,” said Ross Carlyon, a meteorlogical technician for the National Weather Service.
The average low was 33.5 degrees, which was almost 20 degrees above normal. The mean temperature was 44 degrees, which was 14.6 degrees above normal.
In March, 15 daily records were set including the high temperature seven times and the warmest low temperature seven times.
The temperature reached 78 on March 18, one of six days on which the temperature passed 70 degrees. It passed 60 14 times and 50 21 times. A normal March brings six days days above 50, two above 60 and none above 70.
The low was 59 on March 19, breaking the record by 20 degrees.
The warm March follows what was the warmest winter – December, January and February- in St. Cloud history.
Here is a list of warm temperature records set in March .

A message from a Republican meteorologist on climate change
(Paul Douglas, The Huffington Post, March 29, 2012) — I’m going to tell you something that my Republican friends are loath to admit out loud: climate change is real. I’m a moderate Republican, fiscally conservative; a fan of small government, accountability, self-empowerment and sound science. I am not a climate scientist. I’m a Penn State meteorologist, and the weather maps I’m staring at are making me very uncomfortable. No, you’re not imagining it: we’ve clicked into a new and almost foreign weather pattern. … Full story

Three satellites found that 97 percent of Greenland — the land mass second only to Antarctica for its volume of ice — underwent a thaw never before seen in 33 years of satellite tracking, NASA reported Tuesday.
Satellite experts at first didn’t trust their readings, especially since they showed an incredible acceleration. Over four days, Greenland’s ice sheet — which covers 683,000 square miles — went from 40 percent in thaw to nearly entirely in thaw. …
Ice cores from Greenland’s highest region do reveal that such island-wide thaws have happened every 150 years or so, at least over the last few thousand years, but the fear now is that it might occur much more frequently due to warming sea and air temperatures. …

The amount of summer sea ice in the Arctic has reached a record low in three decades of satellite data, scientists reported Tuesday, with one of them describing recent warm years there as creating a “less polar pole.” The decline was expected to continue for at least several more days before cold weather sets in and creates new ice through fall and winter.
The area of Arctic waters covered by sea ice was measured at 1.58 million square miles on Sunday, the National Snow and Ice Data Center (NSIDC) reported. That’s below the previous record low of 1.61 million square miles set on Sept. 18, 2007, and in line with earlier expectations for the season.
“Including this year, the six lowest extents in the satellite record have occurred in the last six years,” the center noted on its website. …
Ted Scambos, a senior NSIDC researcher, told NBC News that no one weather pattern explains the downward trend. “Greenhouse gasses are the only consistent explanation for a persistently warming Arctic,” he added. …
Polar ice melting faster than expected (NBC Nightly News, Nov. 29, 2012) – A new study published in “Science” found the ice in Greenland is melting five times faster than in the early 90s, part of what accounts for a 20 percent rise in sea level over the past two decades.

What had been a blurry picture about polar ice — especially how it impacts sea levels — just got a whole lot clearer as experts on Thursday published a peer-reviewed study they say puts to rest the debate over whether the poles added to, or subtracted from, sea level rise over the last two decades.
“This improved certainty allows us to stay definitively that both Antarctica and Greenland have been losing ice,” lead author Andrew Shepherd of the University of Leeds in Britain, told reporters. Not only that, but the pace has tripled from the 1990s, the data indicate. …
Published in the journal Science, the study was based on input from 47 experts at the 26 institutes that produced earlier studies with wild variations. …
Greenland’s melt rate has gone from 55 billion tons a year in the 1990s to nearly 290 billion tons a year recently, according to the study. …
The findings come as nations negotiate in Qatar over a new climate treaty to replace the 1997 Kyoto Protocol, which aimed to reduce carbon dioxide and other greenhouse gases tied to a warming Earth. …
