The model, used since the 1920s and devised by Norwegian meteorologists, is that when a storm occludes (evolves), it will automatically begin to weaken and pose little danger of severe weather. Instead, some of the biggest storms in the UK's histor
According to new research from MIT, the most recent global climate report fails to capture trends in Arctic sea-ice thinning and drift, and in some cases substantially underestimates these trends. The Intergovernmental Panel on Climate Change (IPCC
Average ice extent for July 2011 was 7.92 million square kilometers (3.06 million square miles). This is 210,000 square kilometers (81,000 square miles) below the previous record low for the month, set in July 2007, and 2.18 million square kilometers
Few words stir up passion and polarization like sustainability. The EPA offers up this description. "The traditional definition of sustainability calls for policies and strategies that meet society’s present needs without compromising the ability of
A new kind of businessman has now arrived in the jungle. The Australian property developer David Nilsson is not seeking rubber or gold, but the carbon dioxide locked up in millions of hectares of lush Amazon rainforest east of Iquitos in Peru.
The Asian giant has been warned by one of its own groundwater experts to either cut its food production or else face "dire" waterlevels, especially in the dry northwest plains. If not, aquifers will sink to "dire" levels not seen in 30 years.
When Willi Dansgaard and Hans Oeschger discovered the 1,500 year cycle in the Greenland ice cores in 1984, they knew immediately that it was solar-powered. They’d seen exactly the same cycle in the carbon 14 molecules in trees, and in the beryllium 1
The area of the Arctic ocean at least 15% covered in ice is this week about 8.5 m sq kilometres – lower than the previous record low set in 2007 – according to satellite
In the two images above you can see the differences between the old normals (1971 to 2000) and the new normals. The top image shows changes in July maximum temperatures. The bottom shows changes in January minimum temperatures. Warmer temperature cha
"La Nina was strong in December," he says. "But back in January it pulled a disappearing act and left us with nothing - La Nada - to constrain the jet stream. Like an unruly teenager, the jet stream took advantage of the newfound freedom--and the
Coal-derived emissions pouring from smokestacks across Asia are--perhaps counterintuitively--responsible for a pause in global warming in the decade following 1998, but that’s no real reason to celebrate.
a good thing human productivity doesn't threaten the global thermostat the way the U.N. would have us believe. If it did, we'd be cooked. Countries rich and poor are backing away
The plants and animals of the southwestern United States are adapted to fire, but not to the sort of super-sized, super-intense fires now raging in Arizona.
If present trends of a 1.5–2ppm annual increase in CO2 levels continue, there is little chance of stabilising greenhouse gas concentrations at 450 ppm. This would only result in a 50% likelihood of limiting global warming to 2C. Climate scientists sa
Kemp and colleagues developed the first continuous sea-level reconstruction for the past 2,000 years, and compared variations in global temperature to changes in sea level over that time period.
Artificial, lab-grown meat requires about 96 percent less greenhouse gas emissions than raising cattle, a recently published study shows.
he United Nations, environmental groups and carbon-offset companies are invested heavily in the idea that planting trees will help slow climate change and global warming. International authorities have long described "afforestation" as a key climat
The Supreme Court on Monday rejected a global warming lawsuit against five big power companies, its most important environmental ruling since 2007 and a victory for the utilities and the Obama administration.
Pollution and global warming are pushing the world's oceans to the brink of a mass extinction of marine life unseen for tens of millions of years, a consortium of scientists warned Monday.
Sunspots may be going into hibernation, a phenomenon unseen since the 17th century that could lead to cooler global temperatures, scientists said Tuesday.
New research published in the journal Science, led by Rensselaer Polytechnic Institute scientist Miriam Katz, is providing some of the strongest evidence to date that the Antarctic Circumpolar Current (ACC) played a key role in the major shift in the
Natural gas burns cleanly, emits half as much carbon dioxide into the atmosphere as burning coal, and is extremely plentiful—especially due to new extraction technologies such as fracking. It seems like a perfect fuel for battling climate change.
As Australian lawmakers debate a national carbon tax, some of the country’s leading climate researchers have been moved to secure locations after receiving threats of physical violence and death.
The report, reconstructing temperatures by examining lake sediment cores in west Greenland dating back 5,600 years, also indicated that earlier, pre-historic settlers also had to contend with vicious swings in climate on icy Greenland. "Climate p

The latest experiment provides evidence for a major component of this theory – how ionization enhances cloud formation. To be converted into droplets and form clouds, water vapour in the Earth's atmosphere needs some kind of surface on which to cond
Tree rings in the US Southwest, the team found, agree well with the 150-year instrumental sea surface temperature records in the tropical Pacific. During El Nino, the unusually warm surface temperatures in the eastern Pacific lead to changes in the
