The world already has warmed a little more than 1 degree Celsius, with the US warming faster than the global average.
The goal of the Paris Agreement is to limit warming to 1.5 degrees Celsius, or at most to 2 degrees Celsius. To do it, the US needs to reach “net-zero” carbon emissions by about 2050, which will require a total clean energy transformation, and will likely require technology to suck our previous planet-warming emissions back out of the atmosphere.
The United States’s emissions need to fall 6% per year. US emissions fell just 12% over the course of nearly two decades between 2007 and 2019.
“Many extremes, including heatwaves, heavy precipitation, drought, flooding, wildfire, and tropical cyclones/hurricanes, are becoming more frequent and severe due to climate change.”
And the disasters are costly, both in terms of lives and dollars. (CNN)
