A global modelling approach shows that in response to rises in global sea level, gains of up to 60% in coastal wetland areas are possible, if appropriate coastal management solutions are developed to help support wetland resilience.
Elevated atmospheric CO2 (550 ppm) could cause an additional 175 million people to be zinc deficient and 122 million protein deficient (assuming 2050 population and CO2 projections) due to the reduced nutritional value of staple food crops.
Climate change will almost certainly cause millions of deaths. Climate engineering might prevent this, but benefits — and risks — remain mostly unevaluated. Now is the time to bring planetary health research into climate engineering conversations.
Strategies that reduce fossil-fuel use can achieve both global carbon mitigation and local health-protection goals. Now research shows the dual benefits of compact urban design and circular economy policies in Chinese cities.
