   Turn Down the Heat: Confronting the New Climate Normal is an analysis of likely impacts of present day (0.8°C), 2°C and 4°C warming above pre-industrial levels on agricultural production, water resources, ecosystem services, and coastal vulnerability across Latin-America and the Caribbean, Middle East and North Africa, and parts of Europe and Central Asia.  It builds on a 2012 Bank report, which concluded the world would warm by 4 degrees Celsius[1] above pre-industrial levels by the end of this century if we did not take concerted action immediately.  
   The report, prepared for the World Bank Group by the Potsdam Institute for Climate Impact Research and Climate Analytics, reveals how rising global temperatures are increasingly threatening the health and livelihoods of the most vulnerable populations, crucially magnifying problems each region is struggling with today. 
   A common threat across the three regions is the risks posed by heat extremes.  State‐of‐the‐art climate modeling shows that “highly unusual” heat extremes, similar to the heat-waves experienced in the US in 2012 and Russia and Central Asia in 2010, increase rapidly under a 4°C emission pathway. 

   It also reveals that the risks of reduced crop yields and production losses for the regions studied increase significantly above 1.5°C to 2°C warming.  It notes that declines in agricultural productivity will also have impacts outside core producer regions, with strong repercussions on food security, and may negatively affect economic growth and development, social stability and well‐being.
