The physics of climate change are very well established. We know how and way certain gases cause heat to be retained. It's well enough known and for long enough that the idea that the earth should be expected to warm as atmospheric GHG concentrations increased due to our fossil fuel combustion is over 100 years old.
People talk a lot about climate models, but what we know about climate change comes from more than a model. We have multiple lines of evidence, many, many proxies, ice core data…lots of data..all of which point to the same conclusion which is consistent with basic physics and that is we have and will continue to experience warming due to anthropogenic build up of GHGs.
We know a GREAT deal about past warming as well and many of the past anomalies are well explained and supported by data. We understand why the earth moves into warm and cold periods and why ice ages happen.
It's not a mystery and it's not a scam. It's not alarmism on the part of scientists and nobody has simple correlations unsupported by causal mechanisms. Our understanding of climate is substantial and well documented. And we should use that knowledge to decide whether or not continuing to pump GHGs into the atmosphere at our current rate is fair to future generations.
Really. VERY WELL established and documented.
