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 […]

Working out how a capital city can be climate neutral by 2050

April 15th, 2013 by Potsdam Institute for Climate Impact Research

Berlin aims to be climate neutral in the year 2050. A team of experts from the Potsdam Institute for Climate Impact Research (PIK), on behalf of the Berlin Senate, the executive body governing the city of Berlin, will work to show how this goal can be achieved. Hans Joachim Schellnhuber, PIK director, said “if the German […]

Increased C02 emissions could lead to more clear air turbulence during transatlantic flights

April 8th, 2013 by Nature Climate Change

Climate change may lead to bumpier transatlantic flights by the middle of the 21st century, suggests work published in the letter “Intensification of winter transatlantic aviation turbulence in response to climate change‘ in the journal Nature Climate Change. The study reports that clear-air turbulence is likely to change significantly with the doubling of carbon dioxide […]

Carbon dioxide can provoke fear

February 4th, 2013 by Nature

The amygdala, a small region of the brain, is not necessarily required for fear and panic in people, according to a study published in the paper ‘Fear and panic in humans with bilateral amygdala damage‘ in the journal Nature Neuroscience. These results are surprising, because decades of research in humans and animals had suggested that […]

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 […]

Greenhouse gases in atmosphere continue to increase in 2011

November 20th, 2012 by World Meteorological Organization

The World Meteorological Organization reports that greenhouse gases in the atmosphere reached a new record high in 2011. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases. According to WMO’s 2011 Greenhouse Gas Bulletin, […]

European Commission promotes efficient living to improve welfare

October 9th, 2012 by European Commission

Connie Hedegaard, European Commissioner for Climate Action, launched on 8 October 2012 a pan-European communication campaign in collaboration with more than 70 organisations from across Europe. Under the slogan “A world you like. With a climate you like” the campaign seeks to put practical solutions at the centre of the climate change debate and demonstrate […]

Global carbon dioxide emissions reached all-time high in 2011

July 26th, 2012 by European Commission Joint Research Centre

Global emissions of carbon dioxide (CO2) – the main cause of global warming – increased by 3% in 2011, reaching an all-time high of 34 billion tonne. In China, the world’s most populous country, average emissions of CO2 increased by 9% to 7.2 tonnes per capita. China is now within the range of 6 to […]

Increased carbon dioxide emissions may significantly decrease survival and growth of some fishes

December 15th, 2011 by Stony Brook University

Fossil fuel combustion, and with it the release of heat-trapping carbon dioxide (CO2), is still growing globally. Beyond climate change, this is also causing the world’s “other CO2 problem,” ocean acidification, i.e., the formation of carbonic acid when CO2 from the atmosphere enters seawater. Previous studies have demonstrated a multitude of negative effects of elevated […]
