Global Warming: Up to 10 percent loss to global GDP due to increase in temperature, these parts of the world will have the biggest impact

If the Earth's temperature increases by 3 degrees Celsius, the world may have to suffer a loss of up to 10 percent of global GDP. This has been said in a new research. Research has also found that it can have the worst impact on poor and hot climate countries and the GDP of these countries can suffer a loss of up to 17 percent.

Half of global economic losses could be linked to extreme heat, according to a study led by ETH Zurich, Switzerland. Analysis of extreme weather events has found that heat waves have the greatest impact on people's lives and economic activities. The study says that rising temperatures will have the greatest impact on countries in Africa and the Middle East.

Researchers have found that when combined with changes in rainfall and temperature patterns around the world, the economic losses caused by climate change increase. Limiting global temperature rise to 1.5 degrees Celsius could reduce projected economic losses by two-thirds, researchers say.

The researchers further found that the costs of climate change increased across the globe after taking into account changes in precipitation and temperature that occur within a short period of time in a location.

For the study, researchers used 33 global climate models and analyzed climate indicators related to both greenhouse gas emissions and income growth for the period 1850-2100. Indicators included annual average temperature, annual rainfall and extreme rainfall.

The researchers acknowledged that substantial uncertainties remain when estimating the cost impacts of climate change. He said the total cost of climate change is likely to be "significantly higher" because the study does not include non-economic impacts, drought, sea-level rise and climate change impacts.
