One billion people would be affected by extreme heat stress if global temperatures rose by 2°C as a result of the climate crisis, according to a study by the British Met Office (COP26) at the 26th session of the United Nations Framework Convention on Climate. Change in Glasgow.
That’s fifteen times the number of people currently affected, the Guardian wrote. However, analysts say recent commitments of countries participating in COP26 to mitigate climate change are causing global temperatures to rise by 2.4 degrees Celsius, well above safe levels, this century.
According to a coalition of researchers from Climate Action Tracker (CAT), with countries committing significant cuts in greenhouse gas emissions by 2030, the Earth will still be warming to a much greater extent by 2100 than the United Nations has set itself.
Also with new commitments “We will be exporting nearly twice as much in 2030 than we will need to maintain the 1.5°C limit.”
CAT analysts believe.
The Bureau of Meteorology has calculated the so-called wet bulb temperature, which is caused by a combination of heat and humidity. At warmer temperatures, the human body can only be cooled by evaporating droplets of sweat that form on the surface of the skin.
The lowest possible temperature that can be achieved by evaporating water under certain air conditions is called wet bulb temperature (WBT). When the temperature reaches 35 degrees Celsius, the body cannot cool itself by sweating, and even healthy people sitting in the shade will die within six hours.
Met office analysis set WBT at 32°C, where workers must rest regularly to avoid heat exhaustion for at least 10 days a year.
If efforts to tackle the climate crisis continue to fail and global temperatures rise by 4°C, half of the world’s population will experience this extreme temperature stress.
Heat is the most obvious greenhouse effect,
Extreme temperatures in cities have tripled worldwide in recent decades
– Stand in the study. In the summer of 2020, more than a quarter of the US population experienced the effects of extreme heat, experiencing symptoms such as nausea and seizures.
At least 166,000 people died worldwide from heat waves in the two decades to 2017, according to the World Health Organization.
The Met Office’s analysis is based on research from the European Union-funded Helix project. The project will work to identify the increased risks of river flooding, wildfires, drought and food shortages. According to him, the habitable part of the world is everywhere affected by at least one influence.
In an optimistic scenario, where individual countries keep their long-term promise to become climate neutral by 2050, global warming could be limited to 1.8°C this century, the Committee against Torture said.
If the world, without any new commitments, continues to move forward, the temperature of the planet could rise by as much as 2.7°C this century. To limit global warming by 1.5°C, greenhouse gas emissions must be reduced by 45 percent by 2030 compared to 2010 levels, and climate neutrality must be achieved by 2050.
