Earth's climate is warming up because of factors like pollution. How much has the Earth's climate warmed over the last 100 years?

According to NASA, the planet has risen its temperature by 0.8 degrees Celcius (1.4 Fahrenheit).

Explanation:

Pollution is, in fact, one of the main factors the Earth's Climate is changing and getting warmer, We are currently sitting at 380 million carbon dioxide ppm emission, which is about 100 million more than the Highest historical Carbon dioxide emission. This type of pollutants that affect the atmosphere by trapping the radiation is one of the reasons the Earth is getting warmer, The current all-time highest CO2 emissions correlate to the rise of almost 1 degree we are experiencing today.

Even if 1 degree seems small a lot of natural processes will be affected dramatically, the ice caps will start melting exponentially, the glaciers ice layer would be smaller and with it, our water resources would reduce, the Coral Reefs will start dying at rapid rates. This and more earth processes would start with the rising of the world's temperature.
