Cost of climate change: 100 mn people will die by 2030
London: The world is set to pay a heavy price if it fails to tackle climate change. As per a report commissioned by 20 governments, more than 100 million people will die and global economic growth will be cut by 3.2 percent of gross domestic product (GDP) by 2030 if steps are not taken to arrest climate change.
The report by humanitarian organisation DARA says that as global average temperatures rise due to greenhouse gas emissions, the effects on the planet, such as melting ice caps, extreme weather, drought and rising sea levels, will threaten populations and livelihoods.
It calculated that five million deaths occur each year from air pollution, hunger and disease as a result of climate change and carbon-intensive economies, and that toll would likely rise to six million a year by 2030 if current patterns of fossil fuel use continue.
As per the report, more than 90 percent of those deaths will occur in developing countries, said the report that calculated the human and economic impact of climate change on 184 countries in 2010 and 2030. It was commissioned by the Climate Vulnerable Forum, a partnership of 20 developing countries threatened by climate change.
"A combined climate-carbon crisis is estimated to claim 100 million lives between now and the end of the next decade," the report said.
It said the effects of climate change had lowered global output by 1.6 percent of world GDP, or by about $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.
It estimated the cost of moving the world to a low-carbon economy at about 0.5 percent of GDP this decade.
