The night before President Barack Obama was set to address Californians stricken by a prolonged drought, White House science czar Dr. John Holdren told reporters that virtually all weather is being impacted by climate change and that droughts were getting “more frequent, they’re getting longer and they’re getting dryer.”

Two prominent climate scientists disagree. Former NASA scientist Dr. Roy Spencer and University of Colorado climate scientist Roger Pielke, Jr. slammed Holdren for his “pseudo-science rambling.”

“The idea that any of the weather we are seeing is in any significant way due to humanity’s greenhouse gas emissions verges on irrationality,” Spencer wrote in his blog.
