I'm not sure what you mean by absolute temperature level vs relative temperature. The reason that these finding are important is because 1. 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
