Current Atmospheric Greenhouse Gas Concentrations Likely Commit to Warmings Greater Than 1.5C over Land

Current levels of atmospheric greenhouse gas concentrations already commit the planet to air temperatures over many land regions being eventually warmed by greater than 1.5°C, according to new research published today (27 July 2016) in the journal Scientific Reports.

The results of the new study have implications for international discussions of what constitutes safe global temperature thresholds, such as 1.5°C or 2°C of warming since pre-industrial times.  The expected extra warming over land will influence how we need to design some cities.  It could also impact on the responses of trees and plants, and including crops.
