Human activity is contributing to the problem, but percentage contribution is a matter for debate. Deforestation and fossil fuel burning definitely are forcing factors, with other activities also contributing. Deforestation is arguably the most significant factor.
Non human forcers (include): - Volcanoes releasing large volumes of green house gases, and melting ice sheets releasing CO2 in volume: Ice traps carbon dioxide far more efficiently than it does oxygen.
H_A is right in saying we can't stop it. It would be nice if "the powers that be" would start to consider devising strategies to cope with it.
