Please educate yourself
The earth DOES go through cycles, however, the earth is heating at a rate never seen before.
The earth has been warming since humans started releasing Co2 from the industrial revolution.
We know that Co2 changes the temperature of the earth based ice, lake bottom, glacial, coral, and tree cores.
We know that co2 levels are 100 ppm higher than they ever have been in history
100ppm higher now is because of human impact, and it is leading to global climate change.
Just a few links to educate yourself,
