The long view
National Climate Assessment: Will U.S. water problems worsen?
Upmanu Lall is director of the Columbia Water Center, chair of Earth and Environmental Engineering, and the lead author of the chapter on water resources in the latest U.S. National Climate Assessment. The report, issued two weeks ago, paints a troubling picture of the nation’s climate future, including projected droughts and extreme precipitation events that could worsen already existing problems with U.S. water supplies and infrastructure. Lall discusses the climate change-driven water challenges the U.S. faces, and ideas for how the nation can respond.
Water security key to unlocking African prosperity
There is mounting evidence of the risks posed by water scarcity to business and economic growth. A 2012 projection by the International Food Policy Research Institute says 45 percent of total GDP — $63 trillion — will be at risk due to water stress by 2050. With coordinated action, better water provision in Africa will strengthen economic growth and unlock the path to prosperity for millions, according to SABMiller’s Chief Executive Alan Clark.
Freshwater vulnerability threatens developing nations' stability
Many nations and regions already facing uncertain political futures must contend with a growing threat to stabilization: freshwater vulnerability. An analysis of 119 low-income countries finds common challenges that could inform broad solutions.
1.5°C vs 2°C global warming: Half a degree makes a big difference
European researchers have found substantially different climate change impacts for a global warming of 1.5°C and 2°C by 2100, the two temperature limits included in the Paris climate agreement. The additional 0.5°C would mean a 10-cm-higher global sea-level rise by 2100, longer heat waves, and would result in virtually all tropical coral reefs being at risk.
