A series of new reports shows how climate change is intertwined with the world’s worsening health, and suggests changes in the global food production system.

An influential group of investors has added its voice to a growing chorus of health professionals and scientists who are calling for radical changes to agriculture and food consumption in an effort to fight climate change, malnutrition and obesity. 

A handful of new reports emphasize that climate change and the world’s worsening health are urgent, intertwined crises.  One of them calls for an international treaty to address the problem. 

A scientific study published Monday also shows how “food production shocks” linked to climate change have been rising globally, putting food security at risk. The researchers identified nearly 230 food production shocks, in 134 countries, from 1961 to 2013, and said the frequency of crop production shocks driven by extreme weather had been increasing steadily.
