The rate of increase has been going up, too. When I first started watching all this, which was 10 years ago or so, the rate was at 3.2 +- 0.4 mm/yr rather than 3.4. I haven't seen an estimate of that acceleration anywhere that gets it just from the data and not from assumptions about models or tipping points. I haven't really looked that hard, though. I'm skeptical of tipping points. Right now, I'm taking a "just what I see in the data" approach because of how politicized everything is. I don't know what the future holds, but I'm not convinced, yet, that it's going to be a complete catastrophe.
