The Madhouse Effect portrays the intellectual pretzels into which denialists must twist logic to explain away the clear evidence that human activity has changed Earth´s climate. Toles´s cartoons collapse counter-scientific strategies into their biased components, helping readers see how to best strike at these fallacies. Mann´s expert skills at science communication aim to restore sanity to a debate that continues to rage against widely acknowledged scientific consensus. The synergy of these two climate science crusaders enlivens the gloom and doom of so many climate-themed books - and may even convert die-hard doubters to the side of sound science.

The Madhouse Effect brilliantly dissects the climate denial industry, empowering all of us to see the facts and take action before it´s too late. Leonardo DiCaprio
