In coastal regions of Asia, people could face the worst effects of global warming.
Climate experts warned that flooding, famine and rising sea levels will put hundreds of millions at risk in one of the world's most vulnerable regions.
According to the Guardian, hundreds of millions of people are likely to lose their homes as flooding, famine and rising sea levels sweep the region.
The report, Climate Change 2014: Impacts, Adaptation and Vulnerability, revealed that for the first half of this century countries such as the UK will avoid the worst impacts of climate change, due to rising carbon dioxide levels.
By contrast, people living in developing countries in low latitudes, particularly those along the coast of Asia, will suffer the most, the report said.
A final draft of the report will be debated by a panel of scientists set up by the Intergovernmental Panel on Climate Change (IPCC) this week at a meeting in Yokohama, Japan.
Scientists warned that millions of people will be affected by coastal flooding and land loss as global temperatures rise, ice caps melt and sea levels rise.
The report added that heat stress, extreme precipitation, inland and coastal flooding, drought and water scarcity, posed risks in urban areas.
In addition, climate change will slow down economic growth, further erode food security and trigger new poverty traps.
