The additional water vapor, acting as a greenhouse gas, absorbs energy that would otherwise escape to space and so causes further warming. (eso.org)
I also think it's fairly clear that the climate sensitivity increases with further warming; that it's not a stable quantity. (carbonbrief.org)
The results of this study contribute to our understanding of how plants and animals will respond to global climate change and highlight the need to slow and prevent further warming. (sciencedaily.com)
