The Paris Agreement, three years on, sparks debate about its ambition and effectiveness. While it provides predictability for climate action, experts note we're "not doing enough" for the 1.5° warming target. Trevor Houser cautions against a binary view; progress has already averted suffering, and more benefits are achievable while aiming for 1.5°-2°.

Rapid global decarbonization, focused on carbon reduction, is crucial. Joshua Goldstein emphasizes that U.S. climate leadership is vital; its absence hinders other nations' goals. Staffan Qvist cites Sweden's successful hydro and nuclear grid, contrasting it with Germany's problematic 100% renewables pursuit.

How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, pragmatic talk, Hayhoe shows how the key to having a real discussion is to connect over shared values like family, community and religion -- and to prompt people to realize that they already care about a changing climate. "We can't give in to despair," she says. "We have to go out and look for the hope we need to inspire us to act -- and that hope begins with a conversation, today."
