“Everything you can touch and depend on in our society goes back to science.”

“The passion and beauty and joy of science is that we humans have invented a process to understand the universe in a way that is true for everyone. We are finding universal truths.”

“Science is the most important thing you can study in school.”

“I encourage you to look at the world around you and think about how it works. My friends, you can go forth and make this world a better place.”

“The Earth has never warmed this fast.”

“When you compare Mars to Earth, and Venus to Earth, you can see the problem [earthlings face]. We do not want to become Venus.”

“When people start rejecting the fundamental understanding of the world that scientific process brings you, well, that's bad in my opinion.”

“I don't want people memorizing the planets or counting how many plants there are in the world. But I want them to know that the world is 4.56 billion years old, and I want them to know how we know it is 4.56 billion years old. It's wonderful and exciting, and it creates a reverence for nature. When I see people reject all that, it's kind of creepy.”

“Evolution is the fundamental idea in all of life science, in all of biology. It's like, it's very much analogous to trying to do geology without believing in tectonic plates. You're just not gonna get the right answer. Your whole world is just gonna be a mystery. Instead of an exciting place.”

“If we continue to eschew science ... we are not going to move forward. We will not embrace natural laws. We will not make discoveries. We will not invent and innovate and stay ahead.”

“Nature is bottom up. It's compelling and complex, and it fills me with joy and it's inconsistent with the top down view.”

“Look at the facts. We need you to change things, not deny what's happening.”

“Good science makes a clean environment.”
