The ancient Maya built large complex cities with towering pyramids and temples that served as centers for a thriving civilization. Follow archaeologists exploring new evidence into the mystery of why after hundreds of years the cities were abandoned.

Quantum entanglement is poised to revolutionize technology from networks to code breaking, but first we need to know it's real. Join physicists as they capture light from across the universe in a bid to prove Einstein's "spooky action at a distance."

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?

It's hard not to notice: our weather is changing. From longer, hotter heat waves, to more intense rainstorms, to megafires and multi-year droughts - the U.S. is experiencing the full range of impacts from a changing global climate. But people on the front lines of these destabilizing weather trends around the country are coming up with new ways to adapt to the many challenges they bring. The lessons they're learning today can help all of us adapt in the years ahead, as the planet gets warmer and our weather gets weirder.

The US recently set an ambitious climate goal: to achieve net zero carbon emissions by 2050. But is that feasible? What exactly would it take? Chasing Carbon Zero takes a hard look at the problem and identifies the most likely real-world technologies that could be up to the task. From expanding renewable energy options and designing more energy-efficient buildings, to revolutionizing the transportation sector, to "negative emissions" technologies, the film casts a hopeful but skeptical eye. A wave of innovation is beginning to take hold, but can these solutions be scaled and made available and affordable across the country? The problem is vast, and time is running out. Find out why there is still hope that we can achieve Chasing Carbon Zero in time to avoid the worst impacts of climate change.
