[Tilley, Al]

1.  Michel Tobis attacked Nafeez Ahmed’s Guardian article on the possibility of catastrophic methane and CO2 releases in the Arctic.  Ahmed’s response is a handy summary of the state of our knowledge on this most significant topic.  http://www.theguardian.com/environment/earth-insight/2013/sep/05/jury-out-arctic-methane-catastrophe-risk-real

2.  Rajendra Pachauri, IPCC head, warns “We have five minutes before midnight.”  http://nz.sports.yahoo.com/news/climate-five-minutes-midnight-ipcc-230852329.html

3.  Some scientists are again raising the prospect of more frequent and narrowly targeted reports to replace the IPCC assessment reports.  http://www.theguardian.com/environment/2013/sep/04/scientists-overhaul-un-climate-report-ipcc

4.  The National Wildlife Federation has released Swimming Upstream: Freshwater Fish in a Warming World—Urgent Action Needed to Protect Freshwater Fish and America’s Waters.  http://www.nwf.org/News-and-Magazines/Media-Center/Reports/Archive/2013/09-04-13-Freshwater-Fish-Climate-Change-Report.aspx

5.  Aquaculture now supplies about half the world’s seafood, but could benefit from certification for sustainable practices.  http://www.sciencemag.org/content/341/6150/1067.short

6.  Climate disruption made about half the world’s extreme weather events of 2012 more likely.  http://www.nbcnews.com/science/study-links-global-warming-some-2012-wild-weather-8C11087012

7.  The US and China has agreed to phase out HFCs, powerful greenhouse gasses.  The accord is estimated to have avoided nearly a degree F of warming, and to ease the way to an agreement on CO2 emissions.  http://www.washingtonpost.com/blogs/post-politics/wp/2013/09/06/u-s-china-strike-new-climate-agreement-at-g-20-summit/   The agreement led to a supportive joint resolution among the G-20 nations.  The nations further agreed to a peer-review process for fossil fuel subsidies expected to lower them.   http://ens-newswire.com/2013/09/06/g-20-to-phase-out-super-greenhouse-gas-fossil-fuel-subsidies/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+ens-newswire%2FJZdj+%28ENS%29

8.  In 2001-11 Greenland lost six times the mass it lost in the previous decade; the Antarctic lost five times as much.  A leaked portion of the IPCC report expects increased sea level rise estimates.  http://www.canberratimes.com.au/environment/seas-may-be-rising-faster-than-predicted-scientists-20130906-2tanz.html
