And they're at risk for lifelong health threats unless the world meets Paris Agreement targets to limit warming to well below 2 degrees Celsius, the scientists reported in the November 14 issue of The Lancet.
About 600 million Indians are at risk from the fallout of a rise in global mean temperature, IndiaSpend on October 8, 2018. "They will bear the vast majority of the burden of climate change", said Dr. Nick Watts, an Australian emergency room physician and lead author of the global report.
The report mentioned "nothing short" of a 7.four p.c year-on-year minimize in Carbon dioxide emissions till 2050 would restrict world warming to 1.5C.
A major academic review of the impact climate change has on human health has found that more than half of the almost 450,000 Canadians evacuated from their homes due to wildfires since 1980 were displaced in the past decade, and says that more than 1,000 Canadians were killed by air pollution related to the transportation industry in 2015.
The report notes that as temperatures rise, infants will bear the greatest burden of malnutrition and rising food prices - average yield potential of maize and rice has declined nearly 2% in India since the 1960s, with malnutrition already responsible for two-thirds of under-5 deaths.
As the decades pass, levels of malnutrition will escalate, the study claims, with global yields of crops such as rice, soy and maize set to plummet as temperatures surpass 2C above pre-industrial levels.
The report warns that rising temperatures will increase the spread of diseases such as mosquito-borne dengue fever and highly infectious diarrhoea caused by Vibrio bacteria, reduce yields for staple crops such as wheat, rice and maize by 4-6 per cent while the world's population soars, increase the risk of malnutrition and price rises, intensify heatwaves, with deaths from extreme temperatures in the United Kingdom rising from 2,000 to 7,000 a year by the 2050s.
While there has been increased public attention to climate change over the past year, governments have not responded on the scale needed, the report said.
50% of the countries surveyed have either completed or are now undertaking a climate change risk assessment. Cereal prices could rise up to 23% by 2050 due to climate change, making cereals unaffordable for the poor, it said, as IndiaSpend on September 2, 2019. Over the past 30 years, the number of climatically suitable days for Vibrio bacteria that cause much of diarrhoeal disease globally has doubled, as per the Lancet report. This not only increases the likelihood of children contracting diseases such as cholera in at-risk regions, it also enlarges their spread.
Children will face more food shortages and infections if climate change continues unchecked, researchers from the World Health Organization and 34 other institutions warn.
Nine of the top 10 years where conditions were most ripe for dengue fever transmission have occurred since 2000, the report said. Around half of the world's population is now at risk. And children, the elderly, the poor and the sick are most hurt during extreme heat with risky overheating, respiratory disease and kidney problems. This is especially damaging to children as their lungs are still developing.
The data gathered by researchers from different universities outlines extensive health damage from climate change, such as risky levels of air pollution contributing to 2,800 premature deaths in Australia in 2016.
On air pollution, the new research calculates that small particulate matter - known as PM2.5 - would cost Europe €129bn a year if emissions remained at 2016 levels.
"It's not something that affects us in 2100; it's something that affects us the 14th of November, 2019".
Most countries have experienced an increase in people exposed to wildfires since 2001-2004 with a financial toll per person 48 times larger than flooding.
India alone saw an increase of more than 21 million exposures, and China around 17 million, resulting in direct deaths and respiratory illness as well as loss of homes, according to the report. The report also said the cholera version of Vibrio has increased almost 10 per cent.
She recalls the 2015 heatwave in India that killed thousands. The researchers found that there were more than 220 million additional heat wave exposures in 2018 for people over 65 compared to the average between 1986 and 2005.
