A preliminary report from the United Nations' climate science advisory council provides the most extensive look yet at how our warming world will affect human health, prosperity, and well-being.

The AFP obtained unprecedented access to the draught of the Intergovernmental Panel on Climate Change (IPCC) report, which is due to be released next year.

Here are some of its results about the effects on humans:

The research demonstrates how climate change has already reduced major crop output internationally and is expected to have an influence on yields all throughout twenty-first century, imposing further pressure on nations with a growing number of mouths to feed.

Between 2015 and 2019, an anticipated 166 million people required humanitarian aid due to climate-related food emergencies, especially in Africa and Central America.

Rising CO2 levels would also damage crop quality by decreasing essential minerals and nutrients in crucial food items.

Despite increased socioeconomic progress, approximately 10 million multiple children would be undernourished and underdeveloped by 2050, subjecting them to a lifetime of health hazards.

If emission levels continue unchecked, the catch potential of marine fisheries — on which millions of people rely as their primary protein supply — is expected to fall by 40 to 70% across tropical Africa.

Reduced red meat consumption and increased consumption of nuts, fruits, and vegetables may cut food-related emissions by up to 70% by mid-century and save 11 million lives by 2030.

Extreme weather will limit people's physical capacity to work, with most of South Asia, Sub-Saharan Africa, and portions of Central and South America losing up to 250 working days per year by 2100.

If globe heats by two degrees Celsius compared to 1.5 degrees – the limit set out in the Paris Agreement – an additional 1.7 billion people would be exposed to severe heat, and an additional 420 million would be vulnerable to intense heat waves.

By 2080, hundreds of millions of city inhabitants in Sub-Saharan Africa, South and Southeast Asia, and the Middle East may endure more than 30 days of lethal heat each year.

Flooding is expected to displace 2.7 million people across Africa each year. Without reductions in emissions, more than 85 million people in Sub-Saharan Africa may even be forced to relocate by 2050 owing to climate-related effects.

Floods might affect two or three times as many people in Colombia, Brazil, and Argentina in a plus 1.5-degree-Celsius world, four times as many in Ecuador and Uruguay, and five times as many as in Peru.

If global warming surpasses three degrees Celsius, an anticipated 170 million people would face severe drought this century.

With such a three-degree Celsius increase in temperature, the number of individuals at high risk of death in Europe will triple comparing to a 1.5-degree increase.

As increasing temperatures extend mosquito habitat, half of the world's population is expected to be at danger of vector-borne illnesses such as dengue fever, yellow fever, and Zika virus by 2050.

Without major reductions in carbon emissions, an extra 2.25 billion people in Asia, Europe, and Africa might be exposed to dengue disease.

Between 2020 and 2050, the number of people displaced from their homes in Asia is expected to increase sixfold.

Severe water shortages lead to, agricultural stress, and sea-level rise, between 31 to 143 million people in Sub-Saharan Africa, South Asia, and Latin America may be internally displaced by the mid-century.
