"Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing ice. The new revelations follows the announcement last week that the collapse of the western Antarctica ice sheet has already begun and is unstoppable, although it may take many centuries to complete."

"Recently NASA reported that this year's maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year's record. This is understandably at odds with the public's perception of how polar ice should respond to a warming climate, given the dramatic headlines of severe decline in Arctic summertime extent. But the "paradox of Antarctic sea ice" has been on climate scientists' minds for some time."

"The Arctic's sea ice melted at a record pace in 2012, the ninth-hottest year on record, compounding concerns about climate change underscored by extreme weather such as Hurricane Sandy, the UN weather agency says."

"A large section of the mighty West Antarctica ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of scientists reported on Monday. If the findings hold up, they suggest that the melting could destabilize neighboring parts of the ice sheet and a rise in sea level of 10 feet or more may be unavoidable in coming centuries."

"Global warming has propelled Earth's climate from one of its coldest decades since the last ice age to one of its hottest -- in just one century. A heat spike like this has never happened before, at least not in the last 11,300 years, said climatologist Shaun Marcott, who worked on a new study on global temperatures going back that far."

"For the first time, researchers have put together all the climate data they have (from ice cores, coral, sediment drilling) into one chart that shows the "global temperature reconstruction for the last 11,000 years":"

"The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era - and of human civilization. Most of these climate changes are attributed to very small variations in Earth's orbit that change the amount of solar energy our planet receives."

"The science behind what makes our planet's temperature rise is pretty straightforward. Pollutants like soot and greenhouse gases like methane and carbon dioxide trap heat within the earth's atmosphere, the global average surface temperature goes up, ice caps melt, sea levels rise and extreme weather events become even more extreme. However, American college students are coming with with some of the coolest ways to battle climate change and clean up domestic energy production."
