What was responsible for the end of the last ice age?

What was responsible for the end of the last ice age?

Posted Wed, 05 Oct 2011 09:08:00 GMT by Dave Collier

A previous explanation for the warming that ended the last ice age has been called into doubt. The last ice age was lengthy, taking place over a period of 25,000 years. It covered over a third of the earth and ended over 10,000 years ago. How the glacial period ended has been a matter of dispute, but one accepted theory was that a significant release of carbon dioxide from the ocean was the cause.

Ozone depletion over the Arctic has been considerably greater this year due to an extended cold period. The ozone layer is an essential component of a life-supporting planet Earth, protecting life from potentially harmful UV radiation and its adverse effects.

Climatic cycles add an additional pressure to that caused by climatic change, trapping species in unfavourable environmental conditions. Examples on land include the deterioration of the body weight of polar bears and the recent overlap of red and arctic fox territories.

The conditions in the Arctic are changing so fast it's becoming hard for scientists to predict the future, but a new study from America says that computer models of ice loss are likely to be accurate.

In the ocean depths: scientists track global warming's 'missing heat'

As global emissions of greenhouse gases have risen, the rise in temperatures has not followed exactly in their path, but scientists using new computer models believe they have found the 'missing heat' of global warming in the depths of the oceans.

Europe's Atlantic fringes have seen significantly warmer waters for the last 30 years – and the fish are responding, says a report on fishery studies in the NE Atlantic. More faster-breeding, warmer-loving fish, and fewer cold-water species are part of the 'swings and roundabouts' pattern being picked up by the study published in Current Biology today.

Physicists observing the Arctic's ice cover say that a new, and ominous, record has been set this year with the ice melting more than ever previously recorded. Since July, scientists at the University of Bremen, who monitor the extent of the Arctic's seasonal melting and freezing, have feared that 2011 would see an even greater melt than the previous largest in 2007.

With the unrelenting weather extremes in the US swinging to firestorms in Texas, after the floods of Irene, the picture of a climate in chaos is a compelling one. But how much can the cause of individual events such of these, even when gathered in a flurry, be pinned to climate change?

A new study finds that crop tillage could play a significant role in measuring greenhouse gas emissions. A team from the USDA-ARS in partnership with the University of Minnesota has found that the tillage of crops can affect levels of greenhouse gas emissions over a specified area of land.

A Stanford University scientist is claiming that action on soot could have immediate and dramatic effects on slowing global warming, and reducing deaths from smoky air. The model being presented at the 242nd American Chemical Society meet suggests that soot is the second-biggest contributor to global warming - but that controlling it could be cheaper, and produce results faster, than the ongoing battle to reduce CO2.

The land of herders and yurts has undergone over two degrees Celsius of warming during the past 70 years. Mongolia, the little-known land sandwiched between China to the south and Siberia to the North is what one expert calls, ''a laboratory for climate change''.

For the first time scientists have linked the stability of modern societies to the global climate. Tropical civil conflicts doubled during the hot and dry El Nino cycles between 1950 and 2004. Researchers have proved that the risk of civil conflict doubles in the hotter and drier conditions prevailing in El Nino years.

How thawing permafrost can increase CO2 emissions and accelerate climate change

How thawing permafrost can increase CO2 emissions and accelerate climate change

Posted Wed, 24 Aug 2011 13:50:21 GMT by Michael Evans

As high-latitude permafrost thaws following climate change, a new study reveals that released CO2 can accellerate the process. Billions of tonnes of carbon are trapped in this permafrost and this will be released as the permafrost begins to thaw and early predictions were that the growth of the new vegetation would pull more carbon from the atmosphere than the permafrost would release.

A NASA project has for the first time mapped the glacial flows of Antarctica, providing vital information in the monitoring of climate change. The map they have created shows glaciers as they snake their way from the desolate Antarctic interior to the southern oceans.
