BEST Study Finds Temperature Changes Explained by GHG Emissions and Volcanoes

I still wonder about those graphs that show CO2 lagging temperature by 800 years during past global warming events.

You still wonder about something that has been *explained* umpteen times, I can image not being interested enough to look stuff up, but please don't involve yourself in a debate if your knowledge is 20 years out of date... (I'm sorry to come over all agressive, but I've this exact argument trotted out for over a decade.)

Long-term climate change (tens to hundreds of thousands of years) is influenced by changes in the orbit of the moon (google Milankovitch if you want).

Slight change in orbit --> causes slight warming --> causes CO2 release --> causes more warming ---> switches between ice-ages & intermediate periods.

The delta-T between the "change in orbit" and the "CO2 release" was about 800 years, which accounts for the lag.

The current change is *different* becuase the CO2 release is not caused by changes in orbit, but by man burning millions of years of stored carbon in a few centuries.

So we're skipping the first bit that ook 800 years, and going almost instantaneously to the "more warming" bit... which is why we are now seeing faster warming of the planet than was ever seen in the climatological records, going back hundreds of thousands of years (and probably much, much longer, but the farther back we go, the harder it becomes to measure how fast temperature changes actually happened).
