Given the heat wave that has occurred in different regions of the world, scientists warned in which year the temperatures on the planet will be dangerously high.
The forecast was published in the scientific journal and points out that CO2 emissions will increase global exposure to dangerous environments in the coming decades.
“Even if the Paris Agreement goal of limiting global warming to 2°C is met, exposure to dangerous heat index levels is likely to increase by 50% to 100% in much of the tropics and increase by a factor of 3 to 10 in many regions around the world”, points out the work carried out by Lucas R. Vargas Zeppetello, Adrián E. Raftery and David S. Battisti.
Without more aggressive emissions reductions than considered possible by our statistical projection, it is likely that by the year 2100, many people living in tropical regions will be exposed to dangerously high heat index values during most days of each typical year. .
“While other greenhouse gases contribute to climate change on decadal to centennial time scales, atmospheric CO2 concentrations are highly correlated with global mean temperature change under a variety of climate change scenarios,” the research says.
By 2100, the median projection is that most regions in the tropics and subtropics will exceed the dangerous heat index threshold on most days each year.
The work points out that many regions in the mid-latitudes will experience dangerous heat index values between 15 and 90 days each year.
In June, they are showing up in much of the western hemisphere of the planet.
The heat wave shown by the space agency mainly affects countries in Europe and extends to the continents of Africa and Asia, and has been captured by satellites that orbit planet Earth and show a catastrophic scenario. In the shared image, shades of yellow and intense red are observed in places where temperatures have exceeded 40 ° Celsius.
