NASA Finds 2011 Ninth-Warmest Year on Record
The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000.
I don’t have much faith that governments are that bothered about this.
Primitive moss-like plants could have triggered the cooling of the Earth some 470 million years ago, say researchers.
A study published in Nature Geoscience may help explain why temperatures gradually began to fall, culminating in a series of "mini ice ages".
Until now it had been thought that the process of global cooling began 100 million years later, when larger plants and trees emerged.
The simple plants' interactions with rocks are believed to be the cause.
"The humble moss has created the climate which we enjoy today, from which the life we see all around us evolved," said Prof Tim Lenton of Exeter University, one of the lead researchers.
Carbon dioxide insulates the planet, rather like a duvet wrapped around it: the higher the concentration of CO2, the higher the average global temperature.

The invasion of the land by plants was a pivotal time in our history. It brought about huge changes to our climate”
Atmospheric levels of the gas 480 million years ago are thought to have been 16 times higher than they are now, and average global temperatures are thought to have been 25C, around 10C higher than they are now.
More than 100 Conservative MPs have written to the prime minister urging him to cut subsidies for wind turbines.
They also want planning rules changed to make it easier for local people to object to their construction.
The Tory MPs - joined by some backbenchers from other parties - questioned the amount of money going to the sector during "straitened times".
But the government said wind farms were a "cost-effective and valuable part of the UK's diverse energy mix".
The challenge to the coalition's policy presents an immediate problem for the new Energy and Climate Change Secretary, Ed Davey. He was promoted to the job following the resignation of fellow Liberal Democrat Chris Huhne last Friday.
Until recently, fossil fuels have widely been seen among scientists and environmental campaigners as a diminishing resource.
Science correspondent Tom Feilden reports on how the discovery of techniques to extract shale gas has rapidly changed the world of energy generation.
A renewed attempt to develop ways of making power stations greener is set to be unveiled by the government.
For the second time in five years, £1bn will be offered for schemes to trap and bury carbon dioxide.
An earlier competition collapsed after all nine entrants pulled out, most citing cost as the main problem.
The last to withdraw was a project run by Scottish Power at its Longannet station in Fife, and the prize money was not awarded
Known as "carbon capture and storage" (CCS), the idea is to prevent CO2 escaping into the atmosphere.
A major part of the government's low-carbon strategy, CCS has been plagued by delays and uncertainty.
A new, detailed record of past climate change provides compelling evidence that the last ice age was ended by a rise in temperature driven by an increase in atmospheric carbon dioxide.
The finding is based on a very broad range of data, including even the shells of ancient tiny ocean animals.
A paper describing the research appears in this week's edition of Nature.
The team behind the study says its work further strengthens ideas about global warming.
A world climate change expert has said the UK should not build any more coal-fired power stations.
Nasa scientist Dr James Hansen was speaking to BBC Scotland ahead of being awarded the prestigious Edinburgh Medal at the city's Science Festival.
Plans have been put forward for coal-fired facilities at Grangemouth and Hunterston in Ayrshire.
Dr Hansen said a mixture of new-build nuclear and renewables was the best combination to prevent climate change.
For the first time, researchers have been able to combine different climate models using spatial statistics -- to project future seasonal temperature changes in regions across North America.
They performed advanced statistical analysis on two different North American regional climate models and were able to estimate projections of temperature changes for the years 2041 to 2070, as well as the certainty of those projections

Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere.
The methane has been trapped by ice, but is able to escape as the ice melts.
Writing in the journal Nature Geoscience, the researchers say this ancient gas could have a significant impact on climate change.
Methane is the second most important greenhouse gas after CO2 and levels are rising after a few years of stability.
There are many sources of the gas around the world, some natural and some man-made, such as landfill waste disposal sites and farm animals.
Tracking methane to these various sources is not easy.
But the researchers on the new Arctic project, led by Katey Walter Anthony from the University of Alaska at Fairbanks (UAF), were able to identify long-stored gas by the ratio of different isotopes of carbon in the methane molecules.
