Maybe you do not agree that the climate change is man-made; but it is clearly happening and we have to do something about it.
Burning less carbon is a good start.
Yes. Climate change is happening. It always has and always will. That's the nature of climate.
We can argue endlessly about the contribution of anthropogenic CO2 emissions to such warming, and the contribution of deforestation and modern agriculture, which cannot be precisely quantified because of the complex, chaotic and non-linear nature of climate.
However, despite these uncertainties, it is clear that significant changes in climate have occurred in the past, with devastating consequences for civilizations in the region. A recent example is the collapse of the Khmer civilization in Cambodia during the 13th and 14th centuries, due to long periods of drought.
Does someone think that reducing CO2 levels would have prevented that Khmer civilization from collapsing?
