serious reading and get your own. I've been following this subject keenly and reading the science on global warming for over thirty years, so have some experience. My work has been in science and my career in R&D management has depended on my judgement informed by my knowledge of physics and chemistry. I've learned to trust it. Science (real science, worked out by 'hardworking scientists', from many disciplines other than climate science and without bureaucratic spin) tells us that our planet warms and cools on a roughly 100,000 yr. cycle, every fourth cycle warmer than those preceeding. (Milankovich, also Berger & Loutre, just to get you started). We are now about 2/3 into the warming phase of one of these warmer "fourth cycles", which will therefore be warmer than for over 400,000 years. Our planet has been warming since the middle of the last ice age about 35k yrs ago and will continue to warm until the peak of the current interglacial in about 15k yrs from now. For about 5k yrs on each side of that peak, global temperatures will be significantly warmer than now and regional climates will be much warmer and wetter. These changes are driven not by CO2 but by the ellipticity of Earth's orbit and the inverse square radiation rule. Work that out for yourself -- the numbers will shock you. The warming from ice age to interglacial is not linear. It is slow at first because of the energy absorbed by the latent heat
