Unbearably Heat in India

Unbearably heat in India- Soon (Climate Change) 7/2018

An analysis of South Asia’s biggest cities found that if current warming trends continued, wet bulb temperatures — a measure of heat and humidity indicating when the body can no longer cool itself — will become so high people directly exposed for six hours or more would die.]

Higher temperatures increase suicide rates in the United States and Mexico

High Temps/Suicide Scholarly Research (Climate Change) 7/2018

Linkages between climate and mental health are often theorized but remain poorly quantified. In particular, it is unknown whether the rate of suicide, a leading cause of death globally, is systematically affected by climatic conditions. Using compre-hensive data from multiple decades for both the United States and Mexico, we find that suicide rates rise 0.7% in US counties and 2.1% in Mexican municipalities for a 1 °C increase in monthly average temperature. This effect is similar in hotter versus cooler regions and has not diminished over time, indicating limited historical adaptation. Analysis of depressive language in  > 600 million social media updates further suggests that mental well-being deteriorates during warmer periods. We project that unmitigated climate change (RCP8.5) could result in a combined 9–40 thousand additional suicides (95% confidence interval) across the United States and Mexico by 2050, representing a change in suicide rates comparable to the estimated impact of economic recessions, suicide prevention programmes or gun restriction laws.
