Among the biggest threats facing people in the warming climate are heat stress, which not only kills people, but can also lead to kidneys and cardiovascular diseases, the report says. Higher temperatures can also reduce the ability of people to work, especially in agriculture, leading to tens of billions of hours of lost working capacity Each year.
Most worrying, according to the authors, is the complicating effect of extreme weather events that are worsened by climate change. Heat waves, floods and storms can suppress public health systems to help people, the report says. Inability to keep emissions, could lead to disasters "Disturb basic public health infrastructure and overwhelm medical services."
The US report, called National Climate Assessment, says extreme rainfall they could overwhelm demanding water and sewer systems that contribute to drinking water shortages and increase exposure to gastrointestinal disease. In some parts of the country, such as Florida and Texas, higher temperatures will benefit from a mosquito that transmits viruses that cause dengue, Zika, chikungunya and yellow fever.
In response to these warnings by the UN Secretary General on Wednesday, António Guterres, called on world leaders to cut greenhouse gas emissions as quickly as three years ago, as promised in the framework of the Paris climate agreement. Nine out of ten people breathe dangerous air, according to the World Health Organization, Guterres he said. "Meeting Paris commitments could save more than a million lives a year," he said.
Reducing emissions from sources such as coal-fired power stations and diesel-fueled trucks would also bring enormous savings for public health systems, Lancet said. "We will do it now, it would be good for us, it would be good for our livelihood and it would be good for the planet," said Dr. Ebi.
