Since the industrial revolution humans have drastically increased the amount of carbon dioxide in the environment. How much is a drastic amount? Since humans started using combustion as a power source roughly 375 billion tons of carbon dioxide has been released.
If that were people, it would be 50 times the number of people on the planet! (The global population is about 7.5 billion people)
If that were miles, it would be 61 round trips from Earth to Pluto (a one way trip to Pluto is 3.67 billion miles)!
If that were pounds that would be the combined weight of a million: blue whales, African elephants, killer whales, great white sharks, giraffes, brown bears, crocodiles, tigers, lions, gorillas, hippopotamuses, and whale sharks each!!!!!
Hopefully you get the drift, it’s an ALARMING amount of carbon dioxide being released.
By releasing so much carbon dioxide you’re causing the earth to heat up at irregular rates. Think of it like this:
Pretend it’s a hot day, it’s 90 °F, you’ve been working in your room for hours, your A/C is broken, and you finally realize that it’s HOT. Since you’ve been in your room for so long all that trapped heat is making you feel HOT and then you start sweating and the more you sweat the HOTTER you feel and the cycle continues over and over until you can’t take it anymore. Wouldn’t it be great if you could open that window to release all that built up heat? Hopefully, you do.
Well, in a way that’s what the earth is experiencing right now. This large amount of carbon dioxide being released is essentially making it increasingly difficult to open that window so you can’t release as much heat which results in the room staying hot. Because carbon dioxide is great at absorbing heat it is preventing the earth from releasing heat to outer space and in turn causing the earth to slowly warm up just like you were warming up in your room.
