The researchers caution that the warming applies to this particular region over a time when wind farms were expanding rapidly. The results are not directly applicable for other regions. They should not be extrapolated over a longer period of time. They also note that the warming is a local effect. It would not contribute to a larger global trend adding to global warming. This is not a situation where large amounts of heat are being generated and released into the atmosphere. What is occurring is the mixing of existing heated air.
To the world's military leaders, the debate over climate change is long over. They are preparing for a new kind of Cold War in the Arctic, anticipating that rising temperatures there will open up a treasure trove of resources, long-dreamed-of sea lanes and a slew of potential conflicts. ...
The U.S., Canada and Denmark held major exercises two months ago, and in an unprecedented move, the military chiefs of the eight main Arctic powers — Canada, the U.S., Russia, Iceland, Denmark, Sweden, Norway and Finland — gathered at a Canadian military base last week to specifically discuss regional security issues.
None of this means a shooting war is likely at the North Pole any time soon.
The world is close to reaching tipping points that will make it irreversibly hotter, making this decade critical in efforts to contain global warming, scientists warned on Monday.
It is almost possible to dismiss Michael Mann’s account of a vast conspiracy by the fossil fuel industry to harrass scientists and befuddle the public. His story of that campaign, and his own journey from naive computer geek to battle-hardened climate ninja, seems overwrought, maybe even paranoid.
climate_desk_bugBut now comes the unauthorized release of documents showing how a libertarian thinktank, the Heartland Institute, which has in the past been supported by Exxon, spent millions on lavish conferences attacking scientists and concocting projects to counter science teaching for kindergarteners.
Mann’s story of what he calls the climate wars, the fight by powerful entrenched interests to undermine and twist the science meant to guide government policy, starts to seem pretty much on the money. ...
Questions about the authenticity of the leaked Heartland Institute documents are fading, as projects described therein are confirmed. Heartland’s senior fellow James Taylor confirmed the existence of the climate-denier classroom curriculum project to ThinkProgress Green yesterday. Now, anti-science blogger Anthony Watts has confirmed that Heartland is funding his project to display weather station data, detailed in the leaked fundraising plan. ...
Although it is important to calibrate weather stations, Watts’ idea that the record of rising temperatures is a result of bad data has been repeatedly debunked. In fact, Richard Mueller, a physicist funded by the Koch brothers to study “flawed” weather stations, confirmed that temperature data is “excellent” and “global warming is real.” ...
Last November, Republicans...killed a no-cost plan to streamline the [National Oceanic and Atmospheric Administration] to provide better services to the public.
Record extreme drought that set Texas on fire last summer also covered much of Mexico. While northern Texas got rain this fall, Mexico didn't. Northern Mexico is suffering through its second year of extreme drought. The North American drought monitor shows severe, extreme and exceptional drought affecting most of Mexico on December 31, 2011.
The most recent U.S. drought map issued today shows severe drought across the southern third of the United States from California to Florida and North Carolina. The southern halves of California and Georgia have been exceptionally dry this winter to date. ...
NASA's Jim Hansen and colleagues have recently released a pre-publication report that concludes the probability was virtually nil that the drought and heat wave in Texas, Oklahoma and Mexico was the result of natural variability. [link, link, and link]
James E. Hansen never thought his decision to study atmospheric models would lead to his arrest. But there he was in handcuffs this summer, protesting at the White House against a pipeline that would carry crude oil from Alberta's oil sands to the Gulf of Mexico.
It wasn't the first arrest, either. Hansen, who has directed NASA's Goddard Institute for Space Studies for 31 years...[testified] before Congress in 1988 on the dangers of global warming. He appeared again in 1989. Then he quietly returned to his work, turning aside television and media requests for the next 15 years because, as he said, "you have no time to do the science if you're talking to the media."
That approach changed in 2004, when he realized government climate policies worldwide failed to reflect the dangerous story his science was telling.

Here's a good explanation of algae blooms in the Great Lakes [link] from Andrew Paterson, a senior scientist with the Ministry of the Environment in Canada.
There appears to be an increase in algae blooms across the Great Lakes...this is particularly evident in Lake Erie where an algae bloom visible from space [link] is an annual occurrence, now.
...Climate change models for the Great Lakes predict less ice cover, more snow, and declining water levels. We may have to add more algae blooms to that list as well.
Gore’s nonprofit climate education and advocacy organization, the Climate Reality Project, recently teamed up with global brand and trend consultants at PSFK to challenge design firms to create an interactive video game that uses the momentum of social media and gaming to advocate taking action on climate change and quash misinformation.
Video games and social media will play a key role in the future of fighting climate change, Gore says...
...today's paper is full of articles... There is one about the extreme heat of yesterday..., about power outages in the city due to an overload on the electrical grid..., about living with extreme heat and changing habits, and about preventing cars from driving in the business center of Buenos Aires.
Believe it or not, none of these articles... presents the views of scientists that don't believe in climate change.

As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates, according to survey results from 41 international scientists published in the Nov. 30 issue of the journal Nature.
Permafrost thaw will release approximately the same amount of carbon as deforestation, authors write. However, the effect of thawing permafrost on climate will be 2.5 times greater because emissions include methane, which is a more powerful greenhouse gas than carbon dioxide.
For those of you who aren’t familiar with me, I am a Republican and a geochemist who, until a few years ago, was quite skeptical about the idea that humans are causing significant climate change.
In the presentation, I briefly talked about how I had made the transition from being a climate change “skeptic” to being an outspoken advocate of mainstream climate science. I then discussed how it is that people like me can so effectively avoid the truth about climate change.
In 2006, Monnett and Gleason published a report describing their sightings of apparently drowned polar bears in the Arctic. The report drew public attention to the plight of the bears as the climate changes and ice melts. ...
Last year, someone at the Department of the Interior alleged that acts of scientific misconduct may have been committed in relation to that report. Some critics of the investigation charge that the scientists were targeted for special attention because of their work's political implications; they say this investigation will have a chilling effect on other researchers.
A myth floats around among those seeking free-market solutions to climate change that insurers will be a positive force. Insurers are worried about the impact of climate on their business model. ...
There’s only one problem: this market-driven solution won’t work.
New developments on the shores of San Francisco Bay won't be approved unless they offer economic or environmental benefits that outweigh the cost of protecting against rising seas, under rules adopted Thursday by regional leaders.
The new rules, written to reduce the risk of flooding as the climate changes, are the most advanced and detailed of their kind in the nation.
...the lack of ice means that the northernmost latitudes are able to be plied by ships in the summer. But every year there is less ice even at maximum, meaning more and more area is accessible year-round. It’s well-known that there are deposits of oil and natural gas up there, and of course the oil companies want access to them. That’s why it’s particularly interesting that Exxon is investing billions of dollars in offshore drilling there, [in effect] saying not only is global warming real, but that its effects will be around for a while.
Arctic scientists say they were not consulted on the latest edition of the Times Atlas of the World, which overstates the effects of climate change
All planets change surface temperatures over time. Earth’s surface warms and cools on several different time scales. But when all factors are accounted for, our world’s surface has been steadily warming by about 1.5 degrees Celsius since the 1880s.
