Holding warming to less than 2C degrees is a real challenge.  Here is a pretty frank review of the difficulties involved, and the many misconceptions.  We should hear a great deal about 2C coming out of the Paris conference, but mostly in more rose-colored tones.  I cannot escape the sense that what Kevin Anderson has to say about it is as close to reality as anyone can get.  This is a good place to start gaining perspective.

A deeper analysis of the Kevin Anderson position.  This piece is a bit more technical than the previous one, and with more content, for those who have the time for extensive study.  Toward the end there are some simple observations about why more experts who are in agreement do not speak out like he does, which applies to all of us.  You can then learn more about Kevin’s views from the two lecture videos at the end, and still more about the subject and what it means from the commentaries that follow.

A frightening report from the Amazon rainforest.  In short, both drought and burning are becoming much worse.  This is a fine piece of independent web journalism from Robert Fanney, with many links to reliable sources.  The map showing last summer’s precipitation decline is especially noteworthy.  A warmer climate is not the whole story, but certainly a big part of it.

Evidence of an earlier period of runaway ice loss in East Antarctica.  This study of an historical precedent supports the growing theory that “the processes leading to instability can be initiated by just minor climate warming…..and it could continue for centuries to millennia.”

A viable way to make good use of collected volumes of CO2.  “The idea is to funnel greenhouse gases from smokestacks or the atmosphere into giant, transparent chemical tanks. Solar cells inside the tanks would spur chemical reactions to turn the greenhouse gases and water into what are sometimes called “solar fuels.”  The primary roadblock to commercial deployment has reportedly been overcome by this means of preventing cells from deteriorating.

A clever new way to increase the energy output of solar cells.  This inexpensive technology would produce about ten percent more energy than current norms. Add it to your hope-chest full of reasons for expecting lower panel prices yet to come.
