1.  Because cattle are inefficient processors of their feed, beef uses far more resources and contributes far more carbon to the atmosphere than its alternatives, including chicken and pork.  http://www.theguardian.com/environment/2014/jul/21/giving-up-beef-reduce-carbon-footprint-more-than-cars

 

2.  Global heat set a new high last month, and the month before.  “We are living in the steroid era of the climate system,” said NOAA’s climate monitoring chief Derek Arndt.  http://mdjonline.com/view/full_story/25472497/article-World-breaks-monthly-heat-record-2-times-in-a-row-?instance=special_coverage_bullets_right_column

 

3.  The heads of state of the US and China are part of a long list of leaders expected for a September UN meeting on climate in New York to prepare for a 2015 conference in France.  Rally organizers hope to have a million marchers to support them.   http://www.theguardian.com/environment/2014/jul/24/barack-obama-xi-jinping-ban-ki-moon-climate-summit

 

4.  A new court ruling would require the government to consider the social cost of carbon released from the extraction of fossil fuels on federal land when permits are requested.  http://www.climatecentral.org/news/social-cost-carbon-court-ruling-17800

 

5.  Renewables provided 55.7% of new energy in the US during the first half of this year.  Solar accounted for about a third of new energy.  Renewables now account for 16.3% of US capacity.    http://www.renewableenergyworld.com/rea/news/article/2014/07/renewables-provide-56-percent-of-new-us-electrical-generating-capacity-in-first-half-of-2014?cmpid=WNL-Wednesday-July23-2014

2.  In under 3 minutes the Rocky Mt. Institute explains why solar and wind ramp up so quickly.  For one thing, if you build a natural gas plant it will produce a certain amount of energy every year.  If you build a pv factory, it will produce energy producers every year.  http://climatecrocks.com/2014/07/18/why-solar-is-taking-over/   In under 4 minutes, Amory Lovins goes on to explain why we need not wait for cheap bulk energy storage to transition to renewables.  http://climatecrocks.com/2014/07/19/the-myth-of-energy-storage-vs-baseload/

 

3.  Stress from climate disruption can lead to cooperation as well as conflict.  Examples are the international cooperation over water supply from the Colorado and Mekong rivers.    The article begins by questioning some of the links claimed between climate stress and conflict.    http://www.huffingtonpost.com/diana-liverman/what-if-climate-change-tr_b_5599886.html

 

4.  Based on a new study State of the Climate in 2013, the head of NOAA’s National Climatic Data Center says that “the climate is changing more rapidly now than it has at any time in the historical record.”  “More than 400 scientists from 57 countries contributed to the report.”  http://news.sciencemag.org/climate/2014/07/report-climate-changing-more-rapidly-any-point-record  Further details from the report:  http://thinkprogress.org/climate/2014/07/18/3461677/noaa-state-of-the-climate-warmer/

 

5.  The BRICS nations have established a bank with $100 b to fund infrastructure and sustainable development.  http://blueandgreentomorrow.com/2014/07/20/brics-100bn-sustainable-development-bank-launched-by-worlds-largest-developing-economies/

 

6.  While melting permafrost releases methane and contributes to heating, a thermokarst lake over millennia becomes a net carbon sink.  http://www.enn.com/ecosystems/article/47608

 

7.  Google Street View cars are now equipped with methane sensors, and some Google city maps are already indicating methane releases.  http://blogs.nature.com/news/2014/07/google-maps-methane-leaks.html

 

8.  WA State just lowered the cost of its residential solar power by standardizing and simplifying the permitting process.  http://grist.org/news/washington-state-just-lopped-up-to-2500-off-the-cost-of-solar-panels-heres-how/?utm_source=syndication&utm_medium=rss&utm_campaign=feed

1.  India is financing their solar program partly by doubling the tax on coal.  Utility-scale solar power is expected to be cheaper than new coal power in India by the end of the decade.   http://reneweconomy.com.au/2014/modi-accelerates-solar-revolution-doubles-tax-on-coal-57890

 

2.  The urgent need to reduce greenhouse gas emissions has recently been posed (by the NY Times, among others) as a choice between acting on CO2, and acting on methane and a package of other forcers more short lived than CO2.  Joe Romm assembles expert testimony that we need to act on all fronts.  http://thinkprogress.org/climate/2014/07/10/3457703/climate-co2-methane/?elq=~~eloqua..type--emailfield..syntax--recipientid~~&elqCampaignId=~~eloqua..type--campaign..campaignid--0..fieldname--id~~

 

3.  Producing metals takes 9.5% of the world’s energy.  Iron and aluminum are the greatest pigs.  http://news.sciencemag.org/climate/2014/07/iron-driver-climate-change

 

4.  NOAA has developed a high resolution climate model able to deal with regional precipitation changes.  It has identified the drying of Southwestern Australia as due to human causes, and predicts increased drying as the century goes on.  http://www.theguardian.com/science/2014/jul/14/southern-australia-faces-water-crisis-by-end-of-century-due-to-climate-change

 

5.  Australian Rupert Murdoch, CEO of News Corporation, which includes Fox and the Wall Street Journal, does not consider that climate disruption has much in store for anyone save low lying islands.  “We shouldn’t be building windmills and all that rubbish.”  http://thinkprogress.org/climate/2014/07/13/3459584/rupert-murdoch-climate-change-rubbish/  As of February 2013, new wind power was cheaper than new coal in Australia.  http://www.bloomberg.com/news/2013-02-06/australia-wind-energy-cheaper-than-coal-natural-gas-bnef-says.html  The Guardian supplies more on Murdoch’s ignorance and its impact.  http://www.theguardian.com/environment/climate-consensus-97-per-cent/2014/jul/14/rupert-murdoch-doesnt-understand-climate-basics
