The Smallest Changes in Temperature Can Have a Huge Impact on Our Planet

This is why global warming can't be ignored.

In a video from MinuteEarth, the channel discusses how a change of 0.8°C (1.4°F) in the air at Earth’s surface makes a big difference. Most of the extra energy from this seemingly tiny temperature change is absorbed by the Earth’s oceans. In fact, the oceans have absorbed the equivalent of an atomic bomb explosion every second for the past century. That heat stored in our oceans is the source of extreme weather.

As water gets warmer at its surface, it is more likely to vaporize into the air. For each degree warmer the air gets, it can hold more water vapor. This means that air over the oceans is sucking up more water than it ever did before, which causes more rain and snow. Meanwhile, air that’s over land is also warmer, so it also sucks up more water vapor. However, because it’s over land, there’s not enough water to vaporize, so the result is harsher droughts.

There have always been hot spots over the oceans, and these are where our planet’s most violent storms have been focused. Now that these hot spots are even hotter, and pulling up even more water vapor, they are causing more violent storms and more serious flooding. Storms, whether or not they’re more frequent, have more heat, water, and power under these conditions. As you can see, even though this temperature change is small, it’s a big deal for the planet.
