Climate change accounts for more than 300,000 deaths per year around the world and $125 billion of economic losses annually, as this factor creates condition where more people feel the effects of natural disasters or suffer environmental degradation, the Global Humanitarian Forum said in a report Friday.

Issued ahead of climate talks in Bonn, Germany next week, the study says the annual death toll from climate change will reach 500,000 people per year by 2030. It is the first report ever solely focused on the global human impact of climate change.

It also found the economic losses due to climate change will have almost tripled to $340 billion annually by 2030.

Climate change is a silent human crisis. Yet it is the greatest emerging humanitarian challenge of our time, former United Nations Secretary General and president of the GHF Kofi Annan said in a statement today.

The Global Humanitarian Forum also found that climate change affects 325 million people, and forecasted this rate could rise to 660 million in twenty years from now.

To avert the worst outcomes climate, change efforts have to be scaled up by a factor of 100 in developing countries, which account for 99 percent of casualties due to climate change, the GHF stated.

Put simply, the report is a clarion call for negotiators at Copenhagen to come to the most ambitious international agreement ever negotiated, or continue to accept mass starvation, mass sickness and mass migration on an ever growing scale, Annan said in the statement.

Governments around the world will meet at U.N. climate talks in Copenhagen in December where they may agree in a new mechanism to stave off global warming.
