World Record-Breaking 2014 Weather And Climate

It isn’t official yet, but 2014 appears to have been the hottest year on the world temperature record. In December, during the U.N. climate talks in Lima, Peru (COP20), the World Meteorological Organization announced in a provisional statement that this conclusion about 2014 weather and climate was virtually certain. WMO bases its report on datasets […]

Alps Study: Climate Change May Worsen Landslides

March 22, 2014, killer landslide near Seattle (photo: Kings County Sheriff’s Office). Last Saturday’s horrific mudslide 55 miles northeast of Seattle may unfortunately herald the shape of landmass movements to come, if climate change has its way with us. A new study in the European Alps elaborates. In a draft article for Elsevier’s Science of […]

Thawing Permafrost Bad News for Global Warming

Permafrost covers almost a quarter of the northern hemisphere, and according to recent calculations contains 1,700 gigatonnes of carbon – that’s an amount twice what is currently in our atmosphere. A new report released by the UN Environment Programme (UNEP) entitled ‘Policy Implications of Warming Permafrost’ warns that the release of this permafrost carbon could seriously amplify […]

Unprecedented 2007 Arctic Fire Released a Year's Worth of Stored Carbon

in 2007, the largest fire ever recorded in the Arctic swept across the Alaskan Northern Slope region, releasing an estimated 2.1 teragrams (2.3 million tons) of carbon into the atmosphere. Researchers estimate that the release of carbon was equivalent to a year’s worth of carbon storage for the entire Arctic tundra biome. Climate warming in the Arctic may lead to a greater frequency of such large fires, putting permafrost at risk of thawing and releasing more CO2.

Arctic Affected by Climate Change More than Expected

• The last five years have been the warmest since 1880 when monitoring began
• Tree ring data suggest that the summer temperatures over the past few decades have been the highest in 2000 years
• Snow cover in May and June has decrease by close to 20%
• The winter season in the Arctic has been shortened by almost two weeks
• There is worry about the decrease in snow and ice cover in the Arctic that will decrease the amount of solar radiation reflected back out into the atmosphere
• Warming is only expected to continue
• Sea level rise by 2100 is expected to be between 0.9 and 1.6 metres, approximately twice what was predicted by the UN panel on climate change

Fires Turn Alaskan Forests Into Carbon Producers

Forests are supposed to reduce carbon dioxide levels, but new research shows that the increase in fires and their tendency to burn larger areas of forest are converting forests into generators of carbon. “Since the proliferation of black spruce, Alaskan soils have acted as huge carbon sinks,” says Evan Kane, a research assistant professor in […]

Melting Permafrost in Siberia, from an International and Local Perspective [VIDEOS]

Here’s a great video from Greenpeace on this important topic. As it notes: “the melting permafrost not only affects the way of life of the indigenous nomadic Nenets people, but also adds burden on climate change due to massive release of methane and carbon dioxide due to decomposion in the defrosting soil.” “Melting Siberian permafrost […]

Hunting for Methane (+ Fun Explosions) [VIDEO]

The release of methane from underneath Arctic ice is expected to be a major issue in coming years as permafrost melts (if we don’t act to stop climate change soon). Methane is about 25 times more potent a greenhouse gas than CO2 over a 100-year time period and about 72 times more potent over a 20-year […]
