The report, commissioned by Climate Vulnerable Forum, a partnership of 20 developing countries threatened by climate change, found out that the increase in temperatures due to greenhouse gas emissions, which causes harmful effects on the planet such as melting ice caps, extreme weather, drought and rising sea levels will threaten populations and livelihoods.
Five million deaths occur each year from air pollution, hunger and disease as a result of climate change and carbon-intensive economies, data showed. The toll would likely rise to six million a year by 2030 if current patterns of fossil fuel use continue. It also said more than 90 percent of those deaths will occur in developing countries.
"A combined climate-carbon crisis is estimated to claim 100 million lives between now and the end of the next decade," the report said.
The effects of climate change had since lowered the global output by $1.2 trillion a year, and losses could double to 3.2 percent of global GDP by 2030 if global temperatures are allowed to rise, surpassing 10 percent before 2100.
The world's poorest nations are the most vulnerable as they face increased risk of drought, water shortages, crop failure, poverty and disease. On average, they could see an 11 percent loss in GDP by 2030 due to climate change, said DARA, the Madrid-based independent humanitarian organization who conducted the report.
