Hamilton vs. Madison and the birth of American partisanship | Noah Feldman

The divisiveness plaguing American politics today is nothing new, says constitutional law scholar Noah Feldman. In fact, it dates back to the early days of the republic, when a dispute between Alexander Hamilton and James Madison led the two Founding Fathers to cut ties and form the country’s first political parties. Join Feldman for some fascinating history of American factionalism — and a hopeful reminder about how the Constitution has proven itself to be greater than partisanship.

Can clouds buy us more time to solve climate change? | Kate Marvel

Climate change is real, case closed. But there’s still a lot we don’t understand about it — and the more we know, the better chance we have to slow it down. One still-unknown factor: How might clouds play a part? They’re critical in regulating earth’s temperature, and there’s a small hope that they could buy us some time to fix things. Climate scientist Kate Marvel takes us through the science of clouds and what it might take for the earth to break its own fever.

Understanding how they form and how they’ll change is important for those that call their banks and deltas home. In this visual-packed talk, geoscientist Liz Hajek shows us how rocks deposited by ancient rivers can be used as a time machine to study the earth’s history, so we can figure out how to more sustainably live on it today.
