"What's it worth to save everything we have?" asks climate scientist Katharine Hayhoe

Why do governments and corporations set Net Zero goals when the science just says to just cut emissions ASAP? For atmospheric scientist Katharine Hayhoe, Chief Scientist at The Nature Conservancy and Director of the Climate Science Center at Texas Tech University., it's too easy for humans to procrastinate on doing stuff 30 or 40 years from now. That's why she says we need more near-term goals with "everything on the table," given what's really at risk is not the planet — but rather us. "So the question is not, 'Could we possibly spend too much trying to fix climate change?' No. The question is, 'What's it worth to save everything we have?'"
