Recent stunning archaeological discoveries are exploding the myth of the Amazon as a primeval wilderness, revealing traces of ancient civilizations that flourished there for centuries. Dense settlements indicate populations in the millions, supported by sophisticated agricultural systems, while huge geometric earthworks and roadways bear witness to complex religious ideas and social networks. The evidence is now clear that, far from being an untouched wilderness, the Amazon has been shaped by human hands for millennia.

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. At the same time, many on the front lines are fighting back – innovating solutions, marshaling ancient wisdom, and developing visionary ideas. 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 more extreme.
