15 Climate Change Facts That You'll Know Are True If You're Not An Idiot

Let's not all get swallowed by floods and eviscerated by drought, ya know?

2. Earth is getting hotter. And the average temperature has increased by 1.5°F over the last century.

That temperature is anticipated to increase another 0.5 to 8.6°F over the next hundred years. The size of the increase largely depends on what we do to cut greenhouse gasses.

3. This is a problem not only because blast furnace summers would suck, but because these changes in temperature — which might seem small — can lead to dangerous changes in climate and weather.

Among those changes include glaciers melting, sea levels rising, and many areas of the planet already seeing severe heat waves, floods, and drought.

4. An estimated 82 million people will endure increases in wildfires due to climate change.

Places like northern California, Western Oregon, and the Great Plains will feel this the most. And these wildfires will increase asthma and deadly respiratory diseases, among other things.

7. It's predicted that sea levels will rise between a foot and and 8.2 feet by 2100. To put that in perspective, if the levels rise by just three feet, 4.2 million American homes would be at a flood risk.

This is according to a report by the National Oceanic and Atmospheric Administration (NOAA) — again, the experts — just so we're all clear.

8. Wild polar bears are facing extinction unless we decrease our levels of greenhouse gases.

Some polar bear populations would go extinct sooner than others. Federal scientists concluded that disappearing sea ice means the "Beaufort Sea population of polar bears will disappear by the end of the century."

10. As of 2015, over 40% of the world's coral reefs have been killed off due to global warming, which could lead many plants and animals toward extinction.

The above photo is of coral bleaching, which occurs when coral reefs detect strong changes in the environment (like temperature), and often leads to destruction of the reef itself.

11. In terms of CO2 emissions (aka global-warming pollution), the US is pretty terrible. While me make up just 4% of the world’s population, we produce 16% percent of all global CO2 emissions.

China is the only country to top us, producing 28% of all CO2 emissions.

14. Luckily, there are actual ways you can help save our planet and cut down on global warming, including small changes like buying LED lightbulbs, making sure your tires are fully inflated, turning off the lights when you leave, and recycling.
