Andrew Revkin: Extreme weather in a warming world

"The need for developing resilience in the face of worst-case weather is glaring and urgent. With or without shifts propelled by the buildup of human-generated greenhouse gases, as populations continue rising in some of the world’s worst climatic “hot zones” — sub-Saharan Africa being the prime example — the exposure to risks from drought and heat will continue to climb, as well. In poor places, the risk is exacerbated by persistent poverty, dysfunctional government and a glaring lack of capacity to track climate conditions and design agricultural systems and water supplies around them." -- Andrew Revkin, "Extreme weather in a warming world"
