Turn down the heat: Climate extremes, regional impacts, and the case for resilience | ReliefWeb

This report focuses on the risks of climate change to development in Sub-Saharan Africa, South East Asia and South Asia. Building on the 2012 report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, this new scientific analysis examines the likely impacts of present day, 2°C and 4°C warming on agricultural production, water resources, and coastal vulnerability for affected populations.

The report finds many significant climate and development impacts are already being felt in some regions, and in some cases multiple threats of increasing extreme heat waves, sea level rise, more severe storms, droughts and floods are expected to have further severe negative implications for the poorest. Climate related extreme events could push households below the poverty trap threshold. High temperature extremes appear likely to affect yields of rice, wheat, maize and other important crops, adversely affecting food security.

Promoting economic growth and the eradication of poverty and inequality will thus be an increasingly challenging task under future climate change. Immediate steps are needed to help countries adapt to the risks already locked in at current levels of 0.8°C warming, but with ambitious global action to drastically reduce greenhouse gas emissions, many of the worst projected climate impacts could still be avoided by holding warming below 2°C.

The first Turn Down the Heat report found that projections of global warming, sea-level rise, tropical cyclone intensity, arid-ity and drought are expected to be felt disproportionately in the developing countries around the equatorial regions relative to the countries at higher latitudes. This report extends this previous analysis by focusing on the risks of climate change to development in three critical regions of the world: Sub-Saharan Africa, South East Asia and South Asia.

While covering a range of sectors, this report focuses on how climate change impacts on agricultural production, water resources, coastal zone fisheries, and coastal safety are likely to increase, often significantly, as global warming climbs from present levels of 0.8°C up to 1.5°C, 2°C and 4°C above pre-industrial levels. This report illustrates the range of impacts that much of the developing world is already experiencing, and would be further exposed to, and it indicates how these risks and disruptions could be felt differently in other parts of the world.
