The "Arctic Paradox" was coined during recent winters when speculations arose that the dramatic changes in the Arctic may be linked to severe snowstorms and cold temperatures in mid-latitudes, particularly along the U.S. east coast and in Europe. Recent studies have illuminated these linkages. Evidence is presented for a physical mechanism connecting Arctic Amplification -- the enhanced warming in high northern latitudes relative to the northern hemisphere -- with the frequency and intensity of several types of extreme weather events in mid-latitudes, such as droughts, floods, heat waves, and cold spells.
Greenland's ice has been melting faster than many scientists expected just a decade ago
The Greenland ice sheet is poised for another record melt this year, and is approaching a "tipping point" into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers.
The ice sheet is the focus of scientific research because its fate has huge implications for global sea levels, which are already rising as ice sheets melt and the ocean warms, exposing coastal locations to greater damage from storm surge-related flooding.
Scientists blame climate change for spread of newly discovered virus, which causes deformed and stillborn lambs
More cases of an exotic virus that has caused deformed and stillborn lambs across England are "inevitable", with the disease potentially spreading across the entire UK, scientists said on Thursday. They blamed climate change for bringing the virus to the country and said other new viruses could follow. Since the Schmallenberg virus was first detected in England in January it has been confirmed on 83 farms from Norfolk to Cornwall, and has left thousands of lambs dead. Across Europe, 1,129 sheep, cattle and goat farms have been confirmed as infected. Germany, where the illness was first detected in August 2011 in the small town that gives the virus its name, has been worst affected. There are also hundreds of infected farms in France, Belgium and the Netherlands.
Plain Spoken Scientist on Climate Change Implications: “Holy ***t!”
Climate Crocks about the recent nature study, which again showed that global temperature, lags Co2 atmospheric concentration amounts. There is a lot of warming in the pipe - incoming.
Jeremy Shakun is lead author of the new study in Nature this week, confirming from multiple proxy records that “temperature is correlated with and generally lags CO2 during the last (that is, the most recent) deglaciation.”
He was interviewed for Nature.com by Paige Brown. (for voice interview, and “plain speech”, see the podcast audio above).
A U.S. Geological Survey (USGS) team has found that a sharp jump in earthquakes in America’s heartland appears to be linked to oil and natural gas drilling operations.
As hydraulic fracturing has exploded onto the scene, it has increasingly been connected to earthquakes. Some quakes may be caused by the original fracking — that is, by injecting a fluid mixture into the earth to release natural gas (or oil). More appear to be caused by reinjecting the resulting brine deep underground.
Permafrost thaw a substantial positive feedback to future warming
The first and largest of these events, the Palaeocene–Eocene Thermal Maximum (PETM), is characterized by a massive input of carbon, ocean acidification and an increase in global temperature of about 5 °C [9°F] within a few thousand years.
