<p><b> | <p><b>However, progress is too slow, to keep below two degrees, we will need to dramatically reduce current emissions and simultaneously remove 10-15 gigatons of CO<sub>2</sub>/yr from the atmosphere by 2050 and scale that to about 20+ gigatons annually by 2100. Depending on how quickly we reduce emissions, the amount we need to remove from the atmosphere scales proportionally.</b></p><p>Greenhouse gas emissions are described in units of tons. It’s hard to think about how much “a ton of gas” really is -- this is how big, at surface temperature and pressure. Here’s an animated video visualizing a bunch of these one-ton balls in New York City.</p> | ||
