Global warming to continue for thousands of years

New York: As there is no new global strategy, researchers said global warming and the damaging climate of carbon emissions will continue and persist for thousands of years.

Rising global temperatures, ice field and glacial melting and rising sea levels are among the climatic changes that could ultimately lead to the submergence of coastal areas that are home to 1.3 billion people today, the study said.

The international team of scientists generated new scenarios for temperature rise, glacial melting, sea-level rise and coastal flooding based on state-of-the-art climate and ice sheet models.

“This long-term view shows that the next few decades offer a brief window of opportunity to minimize large-scale and potentially catastrophic climate change that will extend longer than the entire history of human civilization thus far,” the study said.

The new projections are based on leading research into contemporary and historical climate data, but also new scientific reconstructions of the only comparable period in human history: the last Ice Age.

“This is the most comprehensive look at global climate in the past, present, and future,” said study co-author Jeremy Shakun from Boston College in Massachusetts, US.

“What our analysis shows is that this era of global warming will be as big as the end of the Ice Age. And what we are seeing is a massive departure from the environmental stability civilization has enjoyed during the last 10,000 years of its development,” Shakun noted.

The study was published online in the journal Nature Climate Change.(IANS)

The study said that increased heat may cause illness through undernourishment in a number of ways: reducing appetites, provoking more alcohol consumption, reducing motivation or ability to shop and cook and exacerbate any undernutrition

Global Warming is likely to increase illnesses caused by undernutrition, due to the effects of heat exposure, researchers have warned.

For the study published in the journal PLOS Medicine, the researhers analysed daily hospitalisation data covering almost 80 per cent of Brazil between 2000 and 2015.

They studied the link between daily mean temperatures and hospitalisation for undernourishment according to the International Classification of Diseases.

“The association between increased heat and hospitalisation for undernutrition was greatest for individuals aged over 80, and those 5 to 19 years,” said the researchers from Monash University, Australia.

The researchers found that for every 1 degree Celsius increase in daily mean temperature during the hot season, there was a 2.5 per cent increase in the number of hospitalisations for undernutrition.

“We estimated that 15.6 per cent of undernutrition hospitalisations could be attributed to heat exposure during the study period,” said study’s lead author Yuming Guo.

“Climate change is one of the biggest threats to the reduction of hunger and undernutrition, especially in low and middle-income countries. It has been estimated that climate change will reduce global food availability by 3.2 per cent and thus cause about 30,000 underweight-related deaths by 2050,” the report said.

“It is plausible to speculate that climate changes could not only increase the rate of undernutrition in the most affected areas of the globe, but at the same time, impair individuals’ capacity to adapt to projected rises in temperature,” said the researchers. (IANS)
