NOVA explores ways that scientists are facing the climate challenge.

Weathering the Future: As extreme weather in the U.S. impacts more people–with longer heat waves, more intense rainstorms, megafires, and droughts–discover how Americans are fighting back by marshaling ancient wisdom and innovating new solutions.

Chasing Carbon Zero: The U.S. recently set an ambitious climate change goal: zero carbon emissions by 2050. And to achieve that, slash emissions in half by 2030. Is it possible? And what kind of technology would it take? Meet scientists and engineers who are convinced we can achieve carbon zero in time to avoid the biggest impacts of climate change.

Arctic Sinkholes: Scientists investigate colossal explosions in Siberia and other evidence that rapidly melting soil in the Arctic is releasing vast amounts of methane, a potent greenhouse gas. What are the implications for our climate future?
