The slowing of the jet stream could cause weather patterns to remain in place for longer, resulting in prolonged heat waves or cold snaps.]]> http://blogs.ei.columbia.edu/2012/03/07/climate-change-may-be-affecting-the-jet-stream/feed/ 8 http://blogs.ei.columbia.edu/2012/02/28/epas-greenhouse-gas-rule-poses-challenges-for-us-policy-review-process/ http://blogs.ei.columbia.edu/2012/02/28/epas-greenhouse-gas-rule-poses-challenges-for-us-policy-review-process/#comments Tue, 28 Feb 2012 16:39:26 +0000 Kate Brash http://blogs.ei.columbia.edu/?p=23232 ...]]]> http://blogs.ei.columbia.edu/2012/02/28/epas-greenhouse-gas-rule-poses-challenges-for-us-policy-review-process/feed/ 0 http://blogs.ei.columbia.edu/2011/10/10/what-are-the-keystonexl-pipeline-risks-to-water-resources/ http://blogs.ei.columbia.edu/2011/10/10/what-are-the-keystonexl-pipeline-risks-to-water-resources/#comments Mon, 10 Oct 2011 13:20:52 +0000 Julia Apland Hitz http://blogs.ei.columbia.edu/?p=18683 One of the issues most passionately discussed now in the media and blogosphere is the KeystoneXL Pipeline proposal, to allow Canadian oil and gas company TransCanada to build a pipeline to transfer tar sands oil from Alberta to Texas.

And while these crises often occur simultaneously in different regions, they also happen in the same places as short, fierce bursts of rain punctuate long dry spells.]]> http://blogs.ei.columbia.edu/2011/07/20/the-year-of-drought-and-flood/feed/ 2 http://blogs.ei.columbia.edu/2011/05/01/how-to-reduce-weather-risk-and-make-a-little-green/ http://blogs.ei.columbia.edu/2011/05/01/how-to-reduce-weather-risk-and-make-a-little-green/#comments Sun, 01 May 2011 21:42:11 +0000 Eric Holthaus http://blogs.ei.columbia.edu/?p=14293 People understand that weather can affect certain markets — especially energy prices and other commodities — but its impact on portfolios more broadly might surprise. Just last week, a new study was released that estimated $485 billion of annual weather-related economic impact in the United States alone. Another calculated the effect at nearly 10 times that amount [...]]]> http://blogs.ei.columbia.edu/2011/05/01/how-to-reduce-weather-risk-and-make-a-little-green/feed/ 0 http://blogs.ei.columbia.edu/2011/04/28/can-big-earthquakes-disrupt-world-weather/ http://blogs.ei.columbia.edu/2011/04/28/can-big-earthquakes-disrupt-world-weather/#comments Thu, 28 Apr 2011 16:59:18 +0000 Kim Martineau http://blogs.ei.columbia.edu/?p=14075 The recent earthquake in Japan shifted the earth’s axis by half a foot.
