lowest arctic ice coverage (at 3.41 million square kilometers) and largest melt of the greenland ice sheet (at 97% melted) was set in 2012. in 2008, the u.s. classified the polar bear as a threatened species, the first with its survival at risk due to global warming. “it’s a fact that early sea ice breakup, late ice freeze-up and the overall reduction in ice pack…could erase half of a population in a single year.” - andrew derocher, co author, “rapid ecosystem change and polar bear conservation.” photos by anna henly, flip nicklen and ole jorgen liodden

National Oceanic and Atmospheric Administration climate study puts 2012 among the 10 warmest years on record
Last year was among the 10 warmest years on record – ranking eighth or ninth depending on the data set, according to a report led by the National Oceanic and Atmospheric Administration (Noaa). The year 2012 also saw record greenhouse gas emissions, with concentrations of carbon dioxide and other warming gasses reaching a global average of 392.7 parts per million for the year.
"The findings are striking," Kathryn Sullivan, Noaa’s acting administrator, said on a conference call. "Our planet as a whole is becoming a warmer place."
The scientists were reluctant to point directly to the cause of the striking changes in the climate. But the annual reports are typically used by the federal government to prepare for the future, and in June president Barack Obama used his climate address to direct government agencies to begin planning for decades of warming atmosphere and rising seas.
The biggest changes in the climate in 2012 were in the Arctic and in Greenland, said the report, which is an annual exercise by a team of American and British scientists. The Arctic warmed at about twice the rate of lower latitudes, the report found. By June 2012, snow cover had fallen to its lowest levels since the record began. By September 2012, sea-ice cover had retreated to its lowest levels since the beginning of satellite records, falling to 1.32 million square miles.
2012 broke a number of climate records
While the rise of global temperatures are slowing thanks to La Niña, they’re still getting progressively high each year.
The midwest burned, NYC swam, and the Arctic sea ice set a new record low last September.
Australia’s summer so far has been the hottest on record, too- in January, meteorologists were forced to add two new colors to the weather map to account for record-high temperatures.
I wonder how this summer will be?

NRDC experts analyzed government weather data and found that at least 3,527 monthly weather records were broken for heat, rain, and snow throughout the United States last year. That is higher than the 3,251 records smashed in 2011.
Record heat, Arctic melt, disasters, international wrangling, 2012 was a hot year.
