Dave White’s new environmental science textbook, Climate Crisis Changed: The Intergovernmental Panel on Climate Change Are Deliberate Science Fiction, examines the basic science of what drives climate change. White dives into the evidence used by the Intergovernmental Panel on Climate Change to claim that we face a climate crisis. The evidence doesn’t support the position. Claims of climate catastrophe are based on a faulty understanding of the impact different greenhouses gases have on temperatures and related climate phenomena. White controversially writes that the present warming is impacted by shifts in the earth’s tilt.
