Climate scientists are still grappling with one of the main questions of modern times: how high will global temperatures rise if the atmospheric concentration of carbon dioxide doubles. Many researchers are now turning to the past because it holds clues to how nature reacted to climate change before the anthropogenic impact. The divergent results of this research, however, have made it difficult to make precise predictions about the impact of increased carbon dioxide on future warming. An...

Research Shows Sea-Level Rise Is Much Faster Than Previously Reported
2012-11-28 12:18:17

Lawrence LeBlond for redOrbit.com - Your Universe Online The Intergovernmental Panel on Climate Change (IPCC) has been keeping a close eye on rising sea levels and has released several reports outlining the forecasts for the future of our world´s oceans. In its fourth assessment report, released in 2007, the IPCC estimated sea levels were rising at a rate of 0.08 inches per year based on satellite data. But new research from the Potsdam Institute for Climate Impact Research, Tempo...

Drought Index Calculations Are Flawed
2012-11-18 05:54:28

redOrbit Staff & Wire Reports - Your Universe Online Reports claiming that the climate change has caused global drought conditions to intensify over the past several decades are flawed and based on faulty calculations, according to a new study published Thursday in the journal Nature. According to Anna Salleh of ABC News Australia the researchers report in their study that the 2007 4th Assessment Report (AR4) by the UN Intergovernmental Panel on Climate Change (IPCC) "overestimated"...

More Accurate Climate Models Show Higher Global Temperatures

Alan McStravick for redOrbit.com — Your Universe Online Regardless of which side of the issue you might stand on, regarding climate change and what is going to happen in the future, there is one thing we can all agree on: This summer was HOT! According to a new study funded by NASA, we may want to buckle in because apparently this ride is just beginning and its only going to get hotter. According to analysis by scientists from the National Center for Atmospheric Research (NCAR),...

Scientists argue for adaption policies Governments and institutions should focus on developing adaption policies to address and mitigate against the negative impact of global warming, rather than putting the emphasis on carbon trading and capping greenhouse-gas emissions, argue Johannesburg-based Wits University geoscientist Dr Jasper Knight and Dr Stephan Harrison from the University of Exeter in the United Kingdom. "At present, governments' attempts to limit greenhouse-gas emissions...

Sea Rise Will Be Irreversible Over Next Several Thousand Years Due To Greenhouse Gas Emissions
2012-10-02 15:25:24

Brett Smith for redOrbit.com - Your Universe Online A groundbreaking study by a team of European researchers warns that greenhouse gas emissions will cause an irreversible rise in sea level over the next several thousand years. The study, published in the latest edition of the journal Environmental Research Letters, expanded the scope of typical climate change studies to include thousands of years in its projections and also took into consideration all of the Earth´s land ice,...

Predictions Put To The Test By Climate Scientists
2012-09-19 08:21:49

A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales. Climate-prediction models show skills in forecasting climate trends over time spans of greater than 30 years and at the geographical scale of continents, but they deteriorate when applied to shorter time frames and smaller geographical regions, a new study has found....

The Sustainable Consumption Institute research claims food which families now take for granted, such as meat and fresh vegetables, could become too expensive for many if global temperatures rise in line with the current trends and reach 4°C within the lifetime of many people. Even if families continue to take steps to lower their carbon emissions from energy use, global farming emissions will continue to rise because of our growing appetite for energy-intensive foods and a rising...

Sea levels around the world can be expected to rise by several meters in coming centuries, if global warming carries on The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions. "Sea-level rise is a hard to quantify, yet critical risk of climate change," says Michiel Schaeffer of Climate Analytics and Wageningen University, lead author of the...
