These plots show the amount of deviation in global temperature from its average. It clearly indicates that the Earth is warming up slowly every year. We are moving up significantly from the average temperatures. Especially from 1980, we are in a red zone.
Hot temperatures do not just mean the day is just hotter, so you can relax inside an AC room. Any small difference in atmospheric pressure due to the raised temperatures triggers severe cyclones, hurricanes, Tornadoes, arctic snowstorms, and a rise in sea level.
The world must act quickly to stop this. Otherwise, it is hard to imagine the magnitude of its impact on our next generation. I mean to our kids.
