Climate change is causing 300,000 deaths a year and is affecting 300 million people, according to the first comprehensive study of the human impact of global warming.
The study projects that increasingly severe heatwaves, floods, storms and forest fires will be responsible for as many as 500,000 deaths a year by 2030, making it the greatest humanitarian challenge the world faces.
Climate change is also causing economic losses, amounting to more than US$125 billion a year — more than all the present world aid. The report comes from former UN secretary-general Kofi Annan’s think tank, the Global Humanitarian Forum. By 2030, the report says, climate change could cost US$600bn a year.
Writing in yesterday’s edition of the London-based Guardian newspaper, Rajendra Pachauri, chair of the UN intergovernmental panel on climate change, says: “The scale of devastation is so great that it is hard to believe the truth behind it, or how it is possible that so many people remain ignorant of this crisis.”
Civil unrest may also increase because of weather-related events, the report says: “Four billion people are vulnerable now and 500 million are now at extreme risk. Weather-related disasters ... bring hunger, disease, poverty and lost livelihoods. They pose a threat to social and political stability.”
If emissions are not brought under control within 25 years, the report states that:
• 310 million more people will suffer adverse health consequences related to temperature increases.
• 20 million more will fall into poverty.
• 75 million more will be displaced.
The study also compares, for the first time, the number of people affected by climate change in rich and poor countries. Nearly 98 percent of people seriously affected, 99 percent of all deaths from weather-related disasters and 90 percent of the total economic losses are borne by developing countries. The populations most at risk are in sub-Saharan Africa, the Middle East, south Asia and small Pacific island states.
But of the 12 countries considered least at risk, including Britain, all but one are industrially developed. Together they have made nearly US$72 billion available to adapt themselves to climate change but have pledged only US$400 million to help poor countries.
“This is less than one state in Germany is spending on improving its flood defenses,” the report said.
Annan, who launched the report in London on Friday, said: “The world is at a crossroads. We can no longer afford to ignore the human impact of climate change. This is a call to the negotiators to come to the most ambitious agreement ever negotiated or to continue to accept mass starvation, mass sickness and mass migration on an ever growing scale.”
Annan blamed politicians for the impasse in negotiations and widespread ignorance in many countries.
“Weak leadership, as evident today, is alarming. If leaders cannot assume responsibility they will fail humanity. Agreement is in the interests of every human,” he said.
On Friday, Todd Stern, US President Barack Obama’s special envoy on climate change, said the US planned emission cuts of 17 percent below 2005 levels by 2020 and up to 80 percent cuts by 2050.
“The proposed cuts are around the same as the EU. That would be hard policy, with a cap that gets progressively higher from 2012,” he said.
But he accepted poor countries needed money to adapt.
