[Still from the movie "Disruption. From FilmsforAction.org]

If you stand on one leg on a moving bike, you might fall over. If you do so on the solid ground, you might not. So it feels like the Earth is solid and steady. In fact, the Earth doesn't stand still. It revolves, spins and flies. The spinning powers the systems that churn inside its atmosphere -- winds, heat and rain. Things are always changing. They are changing now, faster than they used to; faster than might be comfortable for us. 

This is a great and shareable video. It's part of "Disruption" (watchable here). It quickly and smartly points to three mechanisms that may trap heat, and then trap more heat, and kill lots of animals that we eat. They are: 

1. Icecap as mirror. 

Hot sun hits the cap, and the whiteness reflects the heat back out to space (unless the CO2 and methane trap it.) For an analogy, note that white clothes, too, keep you cool. Losing the icecaps is the equivalent to putt on a black shirt on a hot day. Will that heat the northern ice further? 

2. Arctic methane. 

Gas is frozen in the tundra. If the tundra opens and belches its guts out, will that methane warm the world? Note that methane is a flammable gas. You can light flatulence. Will methane trap heat beyond what's comfortable for humans? 

3. Ocean acid.

Plankton can't live in acid water. If no plankton, will animals that feed on plankton -- whales, mussels and birds -- live? Will people who live on those proteins thrive?

Lowering CO2 is not about helping the planet. It's about adjusting the thermostat for our home, so that we can live in comfort, and raise our children in a cool, thriving world.
