Climate change threatens mental health

Scientists picked all the information from climate econometrics to understand if there are any links between mental health and climatic conditions in the past.

He said: "Poor mental health during adolescence has an impact on educational achievement and increases the risk of alcohol and substance use and violent behaviour".

A rise in average monthly temperatures is tied to a small increase in mental health issues, according to a study published on Monday in the journal "PNAS". "For example, is poor sleep due to hot temperatures the thing that produces mental health problems?" The question basically asks: "How, over the recent period, has your mental health status been?" Meanwhile, months with an increase of precipitation can increase the probability of mental health issues by 2 percent. The researchers were also able to determine that the people most vulnerable to these consequences were women with lower incomes and previous mental-health issues.

A five year warming of the climate by 1 degree Celsius was associated with a 2 percent rise in mental health problems. The authors explain that yearly warming climates, short term exposure to extremes of weather as well as routine exposure to cycles could have a detrimental effect on the mental health of individuals. They sorted the participants into four groups according to their income and found that the effect of high temperatures on mental health was 60 percent greater for those at the bottom of the economic ladder than for those at the top.

Ryan Coogler Officially Signs On To Write & Direct "Black Panther" Sequel
Marvel now has three films lined-up in the coming year, which are Captain Marvel , Spider-Man Homecoming 2 and Avengers 4 . According to The Hollywood Reporter , Ryan Coogler has inked a deal to write and direct Marvel's Black Panther sequel.

Even small changes in climate can impact human behavior, leading to an increase in fatal auto accidents and a decrease in food safety inspections, according to a study published this year in PNAS.Researchers analyzed data from more than 70 million police stops, more than 500,000 motor vehicle accidents and almost 13 million food safety violations.They found that above 29 degrees Celsius (84 Fahrenheit), police conduct fewer traffic stops, which can contribute to unsafe driving conditions.

Other studies have found a connection between suicide rates and temperature. "Yet for too long, mental health has been mostly an afterthought, despite its overwhelming impacts on communities and young people, everywhere".

He said millions of people are caught up in conflict and disasters, putting them at risk of a range of long-term mental health problems. Patz and his co-authors found that high temperatures impacted admissions for self-harm, including attempted suicide.

"We find that experience with hotter temperatures and added precipitation each worsen mental health, that multiyear warming associates with an increased prevalence of mental health issues, and that exposure to tropical cyclones, likely to increase in frequency and intensity in the future, is linked to worsened mental health", the study's authors wrote. Warmer temperatures will only make those storms worse.Dr. Mona Sarfaty, director of the program on climate and health at George Mason University's Center for Climate Change Communication, said that "when increased rainfall leads to flooding, there can be a mixing of stormwater and sewage that leads to bacterial contamination in the water."That contamination can affect crops too, contributing to foodborne diseases".
