Comments Off on Greenland ice sheet is melting faster and earlier in the year than ever

Climate scientists are beside themselves this month as record-breaking ice melt in Greenland devastates the nation’s ice sheet. New measurements from the Danish Meteorological Institute (DMI) estimate there is melting over 12 percent of Greenland ’s ice sheet. That amount is considerably higher than previous records, and the melt is occurring much earlier this year than normal, leaving scientists with lots of concerns about the future.

James Hansen warns dangerous effects of climate change could hit much sooner than we think

Comments Off on James Hansen warns dangerous effects of climate change could hit much sooner than we think

Last year a working paper led by retired NASA scientist James Hansen incited controversy , and now, the final version of the research is stirring debate once again. In the paper, Hansen and other international scientists warn that the 2°C Paris limit could still cause irreparable damage to our planet, specifically through polar ice melts , superstorms , and rising sea levels that could demolish coastal cities. And those effects could be felt within decades, not centuries. Read the rest of James Hansen warns dangerous effects of climate change could hit much sooner than we think

Record high air and water temperatures in the Arctic are threatening walrus and fish at an alarming rate

Comments Off on Record high air and water temperatures in the Arctic are threatening walrus and fish at an alarming rate

The National Oceanic and Atmospheric Administration (NOAA) reported Tuesday that the Arctic is “warming twice as fast as other parts of the planet.” Arctic temperatures hit a record high this year , more than 2 degrees Fahrenheit warmer than average, with some areas seeing a 2 degree increase over average temps. Scientists say the higher temperatures are drastically changing the habitat of marine life, like walruses, who rely on the sea ice for survival. The melting ice also contributes to rising sea levels around the globe, posing an increased threat to low-lying coastal regions. Logically, warmer air and water temperatures lead to increased ice melting, sending ever more fresh water into the oceans. The NOAA report indicates the largest warming trend is occurring in Chukchi Sea, northwest of Alaska, and Baffin Bay, off the west coast of Greenland. Scientists say Greenland has experienced “extensive” melting over 50 percent of its ice sheet, which leaves ocean water vulnerable to the sun’s rays, resulting in warmer water temperatures. Less ice and warming ocean water pose a threat to the entire ecosystem, with negative impacts on everything from weather to marine life. Related: Greenland’s ice is melting faster than previously thought In particular, NOAA scientists are concerned about fish and walruses. “The decline in sea ice is dramatically changing the habitat for walruses,” the report states, largely because the mammals “traditionally use sea ice for mating, giving birth to young, finding food and shelter from storms and predators.” With less territory to support their livelihoods, walrus are moving to new locales in large numbers. Recently, an estimated 35,000 walruses hauled out (the term for walruses coming out of the water) on a barrier island near Point Lay, Alaska, and other large groups have been spotted through aerial surveys. The large-scale haul outs are problematic to walrus survival, as the overcrowding leads to stampedes that kill calves and increase competition for limited food resources.

NASA satellite shows this glacier just lost the biggest chunk of ice ever recorded

Comments Off on NASA satellite shows this glacier just lost the biggest chunk of ice ever recorded

NASA satellites are pretty nifty, in large part because they capture world events that we might not know about otherwise. That’s what happened recently, when NASA’s Landsat 8 recorded the image above on August 16 of Greenland’s Jakobshavn glacier, which is one of the world’s largest and fastest melting, which. When researchers compared recent images to images captured two weeks ago, they discovered that  the glacier just lost an enormous chunk of ice . So big, in fact, that it may be the largest chunk of ice loss ever recorded. Read the rest of NASA satellite shows this glacier just lost the biggest chunk of ice ever recorded

Comments Off on Greenland’s ice is melting faster than previously thought

The rate of melting ice from Greenland’s ice sheet might be vastly underestimated according to a new study released Monday in Nature Climate Change . Data from satellites led the study to conclude that Greenland is likely to develop more lakes “that speed up melt,” which would add as much as 20 feet to sea levels.

Antarctica’s Ice Loss is Significant Enough to Affect Earth’s Gravity

Comments Off on Antarctica’s Ice Loss is Significant Enough to Affect Earth’s Gravity

Scientists from the European Space Agency recently discovered that the loss of ice in Antarctica is so significant that it’s affecting the Earth’s gravity. The researchers paired data from the ESA’s GOCE satellite with data from the GRACE system of satellites and found that the Earth’s gravity dipped in the area because the ice lost so much mass.

Comments Off on How Global Warming Can Cause Heavier Snowfalls

Residents living in the northeast quarter of the US and parts of Canada have been blasted by a rash of cold weather recently – and it turns out global warming could be behind it . Chris Mooney, host of the Climate Desk , put together an informative report on exactly how global warming could lead to more frequent, heavy snow storms .
