DescriptionEffects of global warming, plotted against changes in global mean temperature.png |
English: This diagram summarizes the effects of global warming. Impacts of climate change are plotted against changes in global mean temperature. Physical, ecological, social, and "large-scale" impacts are plotted against global mean temperature increases (above the 1980-1999 level) from 0 to 5 °C. Add 0.5 °C to measure impacts relative to pre-industrial temperatures.
The arrows on the diagram show that impacts tend to become more pronounced for higher magnitudes of warming. Solid arrows indicate that the projected impact is known with a high level of certainty, while dashed arrows indicate less certainty.
Physical impacts
Ecological impacts
- The larger the increase in temperature, the more species will be at risk of extinction.[7]
- 20-30% of species at risk of extinction (medium confidence) (1.5-2.5 °C / 2.7 – 4.5 °F)[8]
- further extinctions (3 °C / 5.4 °F and above)[7]
Social impacts
- Mix of positive and negative impacts.[9] Low-latitude, less-developed areas are especially vulnerable.[1]
- The negative impacts of climate climate change tend to increase with temperature.[9] Larger temperature increases will be more difficult to adapt to.[10]
Large-scale impacts
