Does this matter? If these results show that the ocean was cooler earlier than we thought, why is that important to our climate change goals? Aren't the absolute temperature level goals more important than the relative temperature goals? And the absolute temperature goals arent affected by this finding.
I am not an ecologist or earth scientist, so please let me know if I am missing something.
- ajuc 3y agoHigh base effect. If you measure growth from erronously high starting point and then base your estimates on that mistakenly low growth rate - you'll significantly underestimate the future values.

The climate goals set in the Paris Agreement are looking realistically more impossible by the day. If this is finding is correct 1.5C is literally impossible and 2C looks implausible given current trajectories 2. This means we've been underestimating the amount of change that has already occurred which means we might be closer to climate tipping points 3. We've been finding that Climate Sensitivity, that is how likely a tipping point like glacier collapses or losing the Amazon Rainforest, is MORE sensitive than we thought. This means lower levels of warming will have bigger impacts. So coupled with already being passed. For example 1.5C is considered the cut off point for which we'll see a global extinction of coral reef ecosystems. Meaning it's likely to late to save 25% of marine ecosystems
