Neither. The current global warming crisis is caused by human burning of fossil fuels.

Probably Neither and both.
The earth is obviously in a warming trend, but mankind could have little to do with it...
Remember, we have had several ice ages in the past, and between them were global warmings. So there are cycles.
Maybe it is because of differences in radiation from the sun, maybe it is caused by increased cosmic radiation due to areas of earths orbits around the sun and meeting with bands of energy every 50 -65 thousand years.
I think a lot more study is needed to be done, and not just the acceptance of Junk Science by some environmentalists.
