5 Clues to Earth’s Climate History

As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And while we can’t know the future for sure, we can get a lot of good clues from the past. Hosted by: Michael Aranda
Cement: A Really Hard Problem

Your Other People’s Videos blog host is going to take a moment to editorialize (a/k/a rant) about these lines, which I usually don’t cut’n’paste from SciShow descriptions:

THE FIGHT TO STOP CLIMATE CHANGE? THAT’S INSANE! YOU CAN’T STOP CLIMATE CHANGE. YOU CAN’T PREDICT CLIMATE CHANGE! YOU CAN’T EVEN PREDICT NEXT WEEK’S WEATHER! ALL OF HUMANKIND IN ALL OF HISTORY CAN BARELY AFFECT LOCALIZED MICROCLIMATES. CO2 IS YOUR FRIEND. THE OZONE HOLE IS CLOSED AND IT’S NOT BECAUSE WE QUIT USING SPRAY CANS. CLIMATE HYSTERIA IS A FRAUD PERPETRATED BY TOTALITARIAN GLOBALISTS, AND BILL GATES SHOULD BE RELIEVED OF ALL HIS WEALTH, WHICH SHOULD BE DISTRIBUTED TO ANYBODY WHO EVER HAD TO DEAL WITH “WINDOWS.”
We now return to our regular program.
Concrete sucks CO2 out of the atmosphere, but making it initially produces a lot of carbon dioxide as a byproduct. Fortunately, by rethinking the chemistry of cement altogether, we can actually use carbon dioxide to create our concrete instead. Hosted by: Hank Green
