Mashable - The most commonly asked questions about climate change, particularly from those who doubt the mainstream findings showing that greenhouse gases are warming the planet, tend to be zombies. They rear their heads again and again, only to seemingly die and then rise once more.
The Earth doesn't have an ideal temperature, and climate deniers like Scott Pruitt know that. Human society has evolved, and flourished, during a period of remarkable climate stability. We're now propelling the climate into an extremely unstable period, characterized by such rapid change that many researchers refer to this as its own geological epoch, known as the "Anthropocene."
"We are perfectly adapted to our current conditions. Any change will be disruptive, expensive, and more likely to be harmful, on the whole, than not," said Katharine Hayhoe, a climate scientist at Texas Tech University, in an email.
