Can Global Warming be Limited to a Maximum of 2oC ?

One of the great scientific myths of this century is that there exists a large number of “magical” solutions to the climate problem that would limit global warming to less than 2oC using technologies that are currently available and economically feasible if only the political will existed to implement those technologies on a massive scale.  Within the last six months, the scientific and engineering community has begun to openly express doubts as to the feasibility of virtually all of these “magical” solutions. [In fairness, many people within the scientific and engineering communities have long harbored doubts concerning the feasibility of the 2oC objective but have hesitated , for a variety of reasons, to openly express those doubts .]

Recent Global Opinion Survey on Climate Change

On November 7, 2015 the Pew Research Center published the results of a global public opinion poll concerning climate change.   It is based on more than 45,000 face-to-face and telephone interviews in 40 countries carried out during the period March 25 through May 27, 2015.

One of the questions asked during the interviews was,

Majorities in all 40 nations polled said that climate change was a serious problem.  Moreover, when the data from all 40 nations was combined, a global median of 54% consider it to be a very serious problem. There are, however, significant regional differences.  Somewhat surprisingly, Chinese and Americans, whose economies are responsible for the greatest annual emissions, are among the least concerned.

Climate Change: Evidence & Causes

 The U.S. National Academy of Sciences and The Royal Society released “Climate Change: Evidence & Causes,” a new publication produced jointly by the two institutions, on February 27, 2014.  It provides an accurate, up to date, and highly readable overview of the current state of climate science.  It can be downloaded from the National Academies web site on climate change.
