Wednesday had to have been a frustrating day for White House Science Advisor Dr. John P. Holdren.
Holdren, a lauded theoretical physicist, appeared before the Republican-led House Committee on Science, Space and Technology on Wednesday to testify about the Obama administration’s plan to fight climate change. But, as is true for all House Science committee hearings on climate change, much of the questioning focused not the content of the plan itself, but whether global warming is even real.
Additional lines of questioning included whether carbon dioxide actually harms human health, and whether the climate plan would lower global temperatures on its own — two questions with complicated answers that have been very thoroughly explained since the plan was introduced. One Congressmen accused Holdren of breaking the law by sending work e-mails from his personal account in 2013, while another said climate scientists shouldn’t be trusted because of their dependence on the existence of climate change to make a living.
Fortunately, Holdren is a confident speaker who was able to succinctly explain the science to his climate denying questioners despite constant interruption. Here are a few of the best times he did just that.
