Global warming will increase heat-related death and disease


In light of last week's government report, the American Public Health Association said the assessment was "a grave reminder" that action is needed to protect public health from climate change. The Lancet Countdown report says that 12.3 million more people experienced a heat wave in 2016 than in 2000 in America. In Africa, 38% are thought to be vulnerable, while in Asia it is 34%.

Greenhouse gas pollution such as is emitted by coal-fired power plants is already linked to deaths in Canada and the world, notes a report in The Lancet.

Leading doctors, academics and policy professionals from 27 organizations have contributed analysis and jointly authored the report.

"One of the report's policy recommendations is to do more research in this area to look at the relationship between climate and mental health so we can cope better".

Prof Hilary Graham, of the University of York from the team of researchers said, "Health is what people feel". A new and important finding this year was the global attribution of deaths to source. The average person used 2% more road-transport fuel in 2015 than they did in 2013, and cycling comprises less than 10% of total journeys taken in three quarters of a global sample of cities. While coal should be a key target for early phase-out in households and electricity generation as it is highly polluting, it is not all that should be done.

Transport is responsible for numerous air pollution problems of urban areas, and levels are generally getting worse. Accordingly, 18 million more people at risk the heat were in last year's waves exposed as 2016.

India saw the output of its workforce decline seven per cent - equivalent to the loss of 75 billion man hours - past year due to heatwave conditions, the 2018 Lancet report on health and climate change said on Thursday.

In India, heat caused the number of hours worked to fall by nearly 7 percent in 2017, Watts said.

India is one of the countries worst hit by heat stress and labour hours lost. The heat is often associated with air pollution in the cities.

The report revealed that among the biggest threats is heat stress.

Rising temperatures and unseasonable warmth is responsible for cholera and dengue fever spreading, with vectorial capacity for their transmission increasing across many endemic areas. As temperatures rise above physiological limits, sustained work becomes more hard affecting output.

Nick Watt, the executive director of the Lancet Countdown, in a statement said, "These are not things happening in 2050 but are things we are already seeing today". In high temperatures, outdoor work, especially in agriculture, is hazardous. "We see them coming at communities all at the same time", she said.

She said the last few summers have alerted Canadians to what climate change is going to look like, with record-breaking forest-fire seasons in British Columbia in both 2017 and 2018, drought on the Prairies, heat waves in central Canada, and flooding in communities nearly from coast to coast.

In the first in-depth report on Australia's progress on tackling climate change health threats, the experts identify risks including malnutrition, heatwaves, disease outbreaks, and mental health problems.

"The world has yet to effectively cut its emissions".

"This is despite strong public desire to do something meaningful about climate change". Following current trends we exhaust our carbon budget required to keep warming below two degrees, by 2032.
