Scripps tweets daily atmospheric C02 reading as it nears 400 ppm

April 23rd, 2013 by Scripps Institution of Oceanography

For the first time in human history, concentrations of the greenhouse gas carbon dioxide (CO2) could rise above 400 parts per million (ppm) for sustained lengths of time throughout much of the Northern Hemisphere as soon as May 2013. To provide a resource for understanding the implications of rising CO2 levels, Scripps Institution of Oceanography […]

Reducing black carbon emissions from diesel engines, wood and coal burners would curb global warming

January 17th, 2013 by International Geosphere-Biosphere Programme

Black carbon is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this issue. The landmark study published in the paper ‘Bounding the role of black carbon in the climate system: A scientific assessment‘ in the Journal of […]

Current atmospheric C02 level must be reduced to protect coastal cities

January 3rd, 2013 by National Oceanography Centre

By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present of nearly 400 parts per million (ppm) were systematically associated with sea levels at least nine metres above current levels. The […]

French climate researchers confirm need to rapidly reduce greenhouse gas emissions

February 15th, 2012 by Le Centre National de la Recherche Scientifique

The French climatology community has just completed a major exercise in the simulation of past and future climate conditions on a global scale. This new body of data confirms the conclusions of the most recent report by the Intergovernmental Panel on Climate Change (IPCC) (2007) on future changes in temperature and rainfall. By 2100, average […]
