“We are seeing the impacts of climate change now in the form of more extreme weather events, sea-level rise, and other changes.”

“We have a moral obligation to future generations to leave them a planet that is healthy and habitable.”

“We need to act now to reduce our greenhouse gas emissions and transition to a clean energy economy.”

“Skepticism is the lifeblood of science. Denial is the rejection of evidence.”

“Denial of the science is not a viable strategy for dealing with climate change.”

“The longer we wait, the more difficult and expensive it will be to address climate change.”

“There is no debate among scientists about the reality of human-caused climate change.”

“The good news is that the solutions to climate change are also opportunities to create jobs, improve public health, and build a more sustainable future.”

“The scientific evidence is now overwhelming: climate change is a present and growing threat to our planet.”

“The 'hockey stick' is a graphic illustration of the simple fact that the planet is running a fever.”

“It’s not about ‘believing’ in climate change. It’s about understanding the science.”

“The forces of denial are well-funded and well-organized, but they are on the wrong side of history.”

“The fight against climate change is not a partisan issue. It's a human issue.”

“The most important thing an individual can do is to talk about climate change with their friends, family, and community.”

“What we're seeing, in a nutshell, is the predictable and predicted consequences of climate change.”
