This letter was first published on September 1, 2015 by a group of twenty climate scientists. The original authors of this letter are now under attack from the climate-denial network. Rep. Lamar Smith (R-Texas), chair of the House Science Committee, has launched an investigation of the lead author of this letter, instead of investigating the trillion-dollar conspiracy of anti-scientific deceit by the fossil-fuel industry.
In solidarity with the scientists now under attack, Climate Hawks Vote is collecting new signatures for this letter.
