It is estimated that sea levels were globally about 6 to 9 meters higher than today during the last interglacial (~130,000 to 115,000 years ago), when CO2 supposedly peaked at 275 ppm (Sommers et al., 2022). It is currently 420 ppm, suggesting that the link between sea level and CO2 is weak.
On the contrary, we are only getting started on sea level rise. The idea of sea level higher than today supports just how strong the co2, temperature connection is. CO2 is a slow steady effect whether its cooling or warming. Climate models predict sea level rise to continue for many more centuries due to our pollution in the atmosphere of co2 and other GHGs.

You are going to have to convince the science community you are right and they are wrong. How are going to do that?
In the end the evidence will convince people. You can ignore it or suppress it, but eventually it will come to the surface. As far as CO2 removal is concerned, there are two big problems. One is the cost. These schemes will work, but they are very expensive, particularly when they are scaled up. Secondly the sheer quantity of CO2 that they are expecting to remove is enormous.
ReplyDeleteAll this to remove a gas that is essential for life and is at a very low level compared with most of the Earth's history.
There is a very clear link between co2 and average earth temperature over the 800,000 years in the ice cores. CO2 is one of our essential ingreidents for life. You are correct in this. It also can change our climate as the ice ages prove to us.
