If there were no humans currently on Earth, would the climate be warming up at present?
I think it is clear that our climate would be warming up now, even if no fossil fuels were ever dug up and burned by humans.
I just submitted the following question into the link/website provided by Sally: "Our climate has recently had an unusual cold spell called "The Little Ice Age" from ~1250-1850. Wouldn't we be warming up naturally from that cold event, unrelated to CO2? Why is this not mentioned anywhere on this website?" I hope they will send me a reply.
