Climate change is already responsible for 300,000 deaths a year and is affecting 300m people, according to the first comprehensive study of the human impact of global warming.

It 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.

Economic losses due to climate change today amount to more than $125bn a year — more than all the present world aid. The report comes from former UN secretary general Kofi Annan’s thinktank, the Global Humanitarian Forum. By 2030, the report says, climate change could cost $600bn a year.

Civil unrest may also increase because of weather-related events, the report says: “Four billion people are vulnerable now and 500m 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:

• 310m more people will suffer adverse health consequences related to temperature increases

• 20m more people will fall into poverty

• 75m extra people will be displaced by climate change.

Climate change is expected to have the most severe impact on water supplies . “Shortages in future are likely to threaten food production, reduce sanitation, hinder economic development and damage ecosystems. It causes more violent swings between floods and droughts. Hundreds of millions of people are expected to become water stressed by climate change by the 2030. “.

The study says it is impossible to be certain who will be displaced by 2030, but that tens of millions of people “will be driven from their homelands by weather disasters or gradual environmental degradation. The problem is most severe in Africa, Bangladesh, Egypt, coastal zones and forest areas. .”

The study compares for the first time the number of people affected by climate change in rich and poor countries. Nearly 98% of the people seriously affected, 99% of all deaths from weather-related disasters and 90% of the total economic losses are now borne by developing countries. The populations most at risk it says, are in sub-Saharan Africa, the Middle East, south Asia and the small island states of the Pacific.

But of the 12 countries considered least at risk, including Britain, all but one are industrially developed. Together they have made nearly $72bn available to adapt themselves to climate change but have pledged only $400m to help poor countries. “This is less than one state in Germany is spending on improving its flood defences,” says the report.

The study comes as diplomats from 192 countries prepare to meet in Bonn next week for UN climate change talks aimed at reaching a global agreement to reduce greenhouse gas emissions in December in Copenhagen. “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 starvartion, mass sickness and mass migration on an ever growing scale,” said Kofi Annan, who launched the report today in London.

Annan blamed politians for the current impasse in the 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 being.”

Barabra Stocking, head of Oxfam said: “Adaptation efforts need to be scaled up dramatically.The world’s poorest are the hardest hit, but they have done the least to cause it.

Nobel peace prizewinner Wangari Maathai, said: “Climate change is life or death. It is the new global battlefield. It is being presented as if it is the problem of the developed world. But it’s the developed world that has precipitated global warming.”

Calculations for the report are based on data provided by the World Bank, the World Health organisation, the UN, the Potsdam Insitute For Climate Impact Research, and others, including leading insurance companies and Oxfam. However, the authors accept that the estimates are uncertain and could be higher or lower. The paper was reviewed by 10 of the world’s leading experts incluing Rajendra Pachauri, head of the UN’s Intergovernmental Panel On Climate Change, Jeffrey Sachs, of Columbia University and Margareta Wahlström, assistant UN secretary general for disaster risk reduction.

The Climate Crisis

What Would it Look Like to Do Everything We Can Imagine?

Climate change is big, the biggest problem we’ve ever faced as a nation. In March, British economist Nicholas Stern said that inaction on climate change could cost the world one-third of its wealth. Last fall, the Global Carbon Project reported that world carbon emissions have risen and are in line with scientists’ worst, most catastrophic scenarios for climate change. Bill McKibben has said, “If we’re to have any chance of heading off catastrophic temperature increase, we have to do everything we can imagine.” How big are our imaginations? What would it look like to do everything we can imagine?

As Congressional leaders and the coal industry try to tell Americans what is and is not possible to do to protect our communities from the disasters of climate change, Obama needs to call on all of us to put our hands and our imaginations to work. It’s critical to have solid federal policy on climate change. But it’s also important to imagine what will become possible as we tackle this challenge. And it’s important for everyone to pitch in. That’s the only way we’ll solve a problem this large.

Obama has already ignited our imaginations, shaken up our sense of what is possible, and gotten us to consider the scope of the problems we face and our roles in solving them. In his November victory speech, he said, “I will ask you to join in the work of remaking this nation the only way it’s been done in America for 221 years—block by block, brick by brick, callused hand by callused hand.” He has brought people to his team like Van Jones, who ask us to consider the climate crisis as a vast opportunity to create green jobs: We’ll need millions of people to get to work, tackling the enormity of building a whole new sustainable economy. And for months Obama has been airing ads calling on us to serve our communities. It’s a start.

But there is more to do.

In the 1940s, the Roosevelt Administration called on Americans across the country to pitch in to the war effort, collect scrap metal, plant victory gardens. There was a “Don’t Travel” campaign to get people to conserve gasoline and tires for the war. And the country came together behind a common cause and mission. The people who weathered this national crisis have been called the “Greatest Generation.”

We have an opportunity to rise to greatness again. The crisis we face today is even larger than what our grandparents confronted. And it will take all of us planting our own gardens, conserving fuel and electricity, putting solar panels on our roofs, transforming our neighborhoods so we can walk and bike instead of drive, greening our buildings, and learning to save, recycle, and reuse.

Solutions will come from the grassroots, but it’s not enough to leave climate change to a handful of volunteers. And it’s not enough to leave a problem as dire as climate change to Congress alone. Obama needs to call on all of us, at every level. Our new president has more innate ability to inspire than perhaps any leader we’ve witnessed in decades. We’ve seen him call us to our best. It’s time for him to do it again.

The most important thing Obama can do is unite us in a common mission: to do everything we can imagine to fight climate change.
