"The World Bank’s World Development Report 2010 finds that climate change at its current rates will lead to “a vastly different world from today, with more extreme weather events, most ecosystems stressed and changing, many species doomed to extinction, and whole island nations threatened by inundation.”
The report is dire: 2 degree Celsius warming, now guaranteed by climate scientists, will result in 100 million to 400 million people at risk from hunger and disease due to increased droughts and flooding, 1 billion to 2 billion will experience water shortages, and per capita incomes will decline 4-5% throughout the developing world as the agriculture and tourism people depend on for their livelihoods declines.
By mid-century, between 25 million and 1 billion people will likely be displaced due to climate change, an analysis by the International Organization for Migration suggests."
