Future risk of record-breaking summer temperatures and its mitigation

Share this Post:

Extremely hot summers will become more likely in future decades, but to what extent? And to what extent will mitigation pathways help to limit the increase of this likelihood compared with a business-as-usual scenario of continued rise of greenhouse gas concentrations?
The probability that summers in the future (2061-2080) will be warmer than any experienced in the past roughly 100 years (1920-2014) was quantified with a climate model for two scenarios: A high-end and an intermediate scenario of climate change. The high-end scenario reflects a business-as-usual scenario of continued fossil fuel use. The intermediate scenario reflects a moderate mitigation pathway of limiting fossil fuel use.
The results show that, on a global basis, the probability of exceeding the historical record temperature (...)
