How Tornadoes ARE Influenced By Climate Change Tornadoes ARE influenced by climate change, despite a recent, misinformed New York Times Op-ed. Granted, not enough standardized measurements exist to talk tornado trends. But tornadoes are heavily influenced by local conditions – specifically, the amount of convective available potential energy (CAPE): the more ground-level heat warms air, the more and faster that air rises. Recently published, reputable Stanford University research indicates that the weakening shear predicted to occur between the equator and poles under global warming isn’t likely to compensate for the tornado-causing strengthening vertical shear that also occurs as the global warming surface heats more than the upper atmosphere.

Green Groups Stage Walk-Out at UN Climate Talks
Posted by John Vidal and Fiona Harvey, The Guardian on Thursday, November 21, 2013
Environment and development groups are protesting at slow speed and lack of ambition of Warsaw negotiations.
Environment and development groups together with young people, trade unions and social movements have walked out of the UN climate talks on Thursday in protest at what they say is the slow speed and lack of ambition of the negotiations in Warsaw.
Wearing T-shirts reading “Volverermos” [“We will return”] around 800 people from organisations including Greenpeace, WWF, Oxfam, 350.org, Friends of the Earth, the International Trade Union conferation and ActionAid, handed back their registration badges to the UN and left Poland’s National Stadium where the talks are being held.
“Movements representing people from every corner of the Earth have decided that the best use of our time is to voluntarily withdraw from the Warsaw climate talks. This will be the first time ever that there has been a mass withdrawal from a COP,” said a WWF spokesman.

Days before world leaders meet in Warsaw, Poland, for the latest United Nations Climate Change Conference, a new report warns that the opportunity to limit global temperature increases to 2 degrees Celsius compared with preindustrial levels is diminishing. The “Emissions Gap Report 2013,” compiled yearly by the United Nations Environment Programme (UNEP), looks at how each nation is meeting its pledge to reduce the release of greenhouse gases. The latest findings suggest that greenhouse gas emissions in 2020 are likely to reach 59 gigatons. Even if nations meet their current climate pledges, emissions would be 8-12 gigatons too high (roughly the equivalent of 80 percent of emissions coming from the world’s power plants right now). A 44-gigaton level, agreed at the 2010 U.N. Climate Conference in Cancun, is needed in 2020 to attain the 2-degree goal. […]
Farming practically collapsed in East-Central Europe after 1989. First came the dissolution of the collective farms, then came the influx of agricultural products from the West, and finally came integration into the European Union. […]
