Age of Ice and Fire

This episode was about earth in the age of humans. For the most part, it's accurate. Species have died off.

Some of the claims are things you hear in the media, but are also simply not true.

They say temperatures are rising at the fastest rate in the last 500 million years. Temps were rising much faster coming out of glacial periods than in the last 100 years.

They say that oceans are acidifying. Go to any ocean and take the PH. It's basic. There's way too much calcium carbonate for them to turn acidic. CO2 is higher than it's been in a few million years, but still far below the average for the last 500m.

They claim that climate change is causing forest fires. Total acres burned are actually lower than it was a century ago.
