The earth tilted 36" closer to the sun this year and closer than ever in recorded history. The sun has been having a lot of solar flare activity as of late. One volcanic eruption can put out as much CO2 as all of the man made CO2 in one year. The Van Allen radiation belt which keeps the suns UV rays and other rays from hitting the earth is getting weaker, and NASA doesn't know why, so more UV rays are hitting the earth. The poles are shifting. Magnetic north is now in Siberia. All this before anything man has done. So yeah, man can't do anything about the above things that are heating the earth.
Now, things man does. Burn fuels that put off CO2, but also asphalt roads in cities cause city temperatures to be about 6 degrees hotter than nearby countryside. Lots of people, lots of big cities, lots of black heat absorbing asphalt roads. But all this is not the only cause, first paragraph shows other causes that are in nature.
We might use less fuel, and build more fuel efficient homes. We could use more concrete roads which is not as hot as asphalt. We could install white roofs on homes and buildings to reflect heat back into space and not absorb heat like dark shingles or tar roofs. We could plant more trees and grow more food in greenhouses. We could build homes semi-underground.
Even if we did everything we could including electric cars, the earth is still going to warm because of the first paragraph. It happens, the earth goes through cycles.
