| Zusammenfassung |
| Global temperature targets, such as the widely accepted 2°C and 1.5° limits, may fail to communicate the urgency of reducing CO2 emissions. Translation of CO2 emissions into regional- and impact-related climate targets could be more powerful because they resonate better with national interests. We illustrate this approach using regional changes in extreme temperatures and precipitation. These scale robustly with global temperature across scenarios, and thus with cumulative CO2 emissions. This is particularly relevant for changes in regional extreme temperatures on land, which are much greater than changes in the associated global mean. Linking cumulative CO2 emission targets to regional consequences, such as changing climate extremes, would be of particular benefit for political decision making, both in the context of climate negotiations and adaptation. |
