MOSCOW (September 30, 2003) — About 160,000 people die every year from side-effects of global warming ranging from malaria to malnutrition and the numbers could almost double by 2020, a group of scientists said on Tuesday.
The study, by scientists at the World Health Organization (WHO) and the London School of Hygiene and Tropical Medicine, said children in developing nations seemed most vulnerable.
“We estimate that climate change may already be causing in the region of 160,000 deaths…a year,” Professor Andrew Haines of the London School of Hygiene and Tropical Medicine told a climate change conference in Moscow.
“The disease burden caused by climate change could almost double by
2020,” he added, even taking account of factors like improvements in
health care. He said the estimates had not been previously published.
Most deaths would be in developing nations in Africa, Latin America and Southeast Asia, which would be hardest hit by the spread of malnutrition, diarrhea and malaria in the wake of warmer temperatures, floods and droughts.
“These diseases mainly affect younger age groups, so that the total
burden of disease due to climate change appears to be borne mainly by
children in developing countries,” Haines said.
Milder winters, however, might mean that people would live longer on average in Europe or North America despite risks from heatwaves this summer in which about 15,000 people died in France alone.
Haines said the study suggested climate change could “bring some
health benefits, such as lower cold-related mortality and greater
crop yields in temperate zones, but (that) these will be greatly
outweighed by increased rates of other diseases.”
Russia is hosting a World Climate Change Conference this week to discuss how to rein in emissions of gases like carbon dioxide from factories and cars that scientists blame for blanketing the planet and nudging up temperatures.
Russian President Vladimir Putin, who opened the conference on
Monday, suggested in jest that global warming could benefit countries
like Russia as people “would spend less money on fur coats and other
But Putin also backed away from Russia’s earlier pledge to swiftly ratify the key Kyoto pact on curbing global warming, a plan that will collapse without Moscow’s backing.
He told 940 delegates to the conference Russia was closely studying the issue of Kyoto. “A decision will be taken when this work is finished,” he said, giving no timetable.
Haines said small shifts in temperatures, for instance, could extend the range of mosquitoes that spread malaria. Water supplies could be contaminated by floods, for instance, which could also wash away crops.
