The report 'Suffering the Science - Climate Change, People and Poverty', combines the latest scientific observations on climate change, and evidence from the communities Oxfam works with in almost 100 countries around the world, to reveal how the burden of climate change is already hitting poor people hard.
The report warns that without immediate action 50 years of development gains in poor countries will be permanently lost. It says that climate-related hunger could be the defining human tragedy of this century.
Climate change's most savage impact on humanity in the near future is likely to be in the increase of hunger. Some of the world's staple crops, such as maize and rice, are very susceptible to rising temperatures and to more unpredictably extreme seasons. Almost without exception, the countries with existing problems in feeding their people are those most at risk from climate change.
Science is now as certain as it can be of harmful climate change. The only real uncertainty is about how much climate change and human suffering we are willing to allow and bear.
