The Stream, April 22: Paris Climate Deal To Be Signed On Earth Day

The Global Rundown

Countries from around the world are prepared to sign a global deal to cut carbon emissions today. Scientists found that droughts, sea level rise, and heatwaves could be significantly worse if global temperatures rise 2 degrees Celsius instead of 1.5 degrees Celsius. Developers have abandoned the controversial Conga gold and copper mine project in Peru. Aid organizations warned that stagnant water left in the aftermath of Ecuador’s earthquakes could facilitate the spread of Zika and other diseases. Denver, Colorado is expanding its efforts to reuse partially treated wastewater.
