New Climate Model Claimed To Be More Accurate

Written by , on December 1, 2011

A study published in Science journal, claims to have narrowed the range by which the world’s temperature can be expected to rise with a doubling of carbon dioxide concentrations from pre-industrial levels. Earlier studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2007 report, have precicted a rise of between 2.0°C and 4.5°C, with a […]  Read more »

New Research Estimates Larger Sea Level Rise

Written by , on May 9, 2011

In 2007, the IPCC projected a maximum sea level rise of 59 centimetres by 2100. The IPCC acknowledged that this was likely to be an under-estimate because understanding of the processes happening on ice sheets was inadequate to enable reliable estimates to be made. A team of researchers led by Eric Rignot from Nasa’s Jet […]  Read more »

Greenland Ice Sheet Not Slipping into the Sea

Written by , on January 27, 2011

Until now, it had been thought that melting ice could form a slippy layer at the bottonm of the Greenland ice sheet causing it to slide rapidly into the sea. Now, a study by Professor Andrew Shepherd of the University of Leeds, has shown that this is not happening. Professor Shepherd’s team used satellite imagery […]  Read more »

Global Temperatures Continue to Rise

Written by , on January 13, 2011

NASA’s Goddard Institute for Space Studies, the UK Met Office Hadley Centre and the US National Oceanic and Atmospheric Administration’s National Climatic Data Center have all reported that 2010 was the warmest year (equally with 2005) since global records were begun in 1880. This is NASA‘s updated graph of global temperatures from 1880 to 2010.  Read more »

How Warming Sometime Makes It Cold

Written by , on December 27, 2010

Northern Europe and northern parts of the United States and Asia are currently experiencing extreme cold and, particularly, heavy snow falls. We have long been told that this sort of thing is just a weather variation that can happen even if the climate as a whole is getting warmer. But new research from NASA’s Goddard […]  Read more »

Climate Update: Good and Bad News

Written by , on December 7, 2010

The UK Met Office has produced the first comprehensive review of climate change since the 2007 report by the Intergovernmental Panel on Climate Change. First the good news: According to the IPCC report, average ocean rises of up to 4 metres could occur by the end of the century. Further research has resulted in a […]  Read more »

Engineering Crops to Reduce Warming

Written by , on November 12, 2010

Researchers at Bristol University are investigating the possibility that developing crop plants, such as wheat, with broad shiny leaves could reflect a substantial amount of sunlight and help to reduce global warming.  Read more »

NASA Study: CO2 More Significant in Greenhouse Effect Than Previously Thought

Written by , on October 16, 2010

Although water vapour and clouds are the major contributors to Earth’s greenhouse effect, a new NASA atmosphere-ocean climate modeling study shows that the planet’s temperature ultimately depends on the atmospheric level of carbon dioxide. The study, conducted at NASA’s Goddard Institute for Space Studies, clarified the role that greenhouse gases and clouds play in absorbing […]  Read more »

Help Research Climate from Old Ship Logs

Written by , on October 13, 2010

The Old Weather Project is looking for volunteers to extract data and weather observations from digital versions of handwritten historical ship log books, which are difficult for a computer to read. Covering 280 ships between 1905 and 1929, the information will enable scientists to reconstruct wind speed, weather, cloudiness, precipitation and pressure for a better […]  Read more »
