The number of city dwellers exposed to dangerous levels of heat and humidity has tripled in little more than one human generation, from 1983 to 2016, concludes a new study published this week in the Proceedings of the National Academy of Sciences (PNAS). By 2016, at least 1.7 billion were exposed to multiple days during which temperatures and humidity rose to levels at which even very healthy people found it debilitating to work outdoors, the study of more than 13,000 cities states. And in a separate study, researchers warn that the combined impact of climate change and forest loss in Brazil could expose more than 11 million people to extreme enough heat stress to produce dehydration, exhaustion, collapse ,and even death.

Three scientists have been awarded the 2021 Nobel Prize in Physics for their work to understand complex systems, such as the Earth’s climate. Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi were announced as the winners at an event in Stockholm. Research by Manabe and Hasselmann led to computer models of the Earth’s climate that can predict the impact of global warming. The winners will share the prize money of 10 million krona (£842,611). It is incredibly difficult to predict the long-term behaviour of complex physical systems such as the climate. Computer models that anticipate how it will respond to rising greenhouse gas emissions have therefore been crucial for understanding global warming as a planetary emergency.
