Hansen Study: Extreme Weather Tied to Climate Change | Climate Central

Hansen Study: Extreme Weather Tied to Climate Change | Climate Central | Nuevas Geografías | Scoop.it
A new study by NASA's James Hansen finds that extreme weather events, such as recent heat waves, are a direct consequence of global warming.

 

Extreme weather events, such as the heat waves that have broiled the High Plains and Midwest this summer, smashing thousands of temperature records, are a direct consequence of global warming, according to a new study led by prominent climate scientist, James Hansen of NASA. The study seeks to reframe how people view the links between manmade global warming and extreme weather events, going farther than ever before in making direct ties between the two.

The study by Hansen, who first warned of the consequences of manmade global warming in landmark Senate testimony in 1988, shows that a new category of extremely hot summers has become far more common than would ever have happened without the buildup in heat-trapping greenhouse gases from human activities.

 

“I don’t want people to be confused by natural variability — the natural changes in weather from day to day and year to year,” Hansen said in a press release. “We now know that the chances these extreme weather events would have happened naturally — without climate change — is negligible.”

America and the West’s dirty little secret

America and the West’s dirty little secret | Nuevas Geografías | Scoop.it
By importing goods from polluting factories in Asia, Americans and others in developed countries underwrite carbon emissions...

 

This is a compelling question: are reductions in greenhouse gases best measured by production or consumption?  The question that this article is posing is essentially trying to find blame for greenhouse gas emmision, but thinking geographically, ponders where along the commodity chain should the bulk of the blame be placed.  What do you think?
