Climate change, explained

ILULISSAT, GREENLAND - JULY 20: An iceberg floats through the water on July 20, 2013 in Ilulissat, Greenland. As Greenlanders adapt to the changing climate and go on with their lives, researchers from the National Science Foundation and other organizations are studying the phenomena of the melting glaciers and its long-term ramifications for the rest of the world. In recent years, sea level rise in places such as Miami Beach has led to increased street flooding and prompted leaders such as New York City Mayor Michael Bloomberg to propose a $19.5 billion plan to boost the citys capacity to withstand future extreme weather events by, among other things, devising mechanisms to withstand flooding.

SANTA CRUZ PROVINCE, ARGENTINA - NOVEMBER 27: Ice calves at the Perito Moreno glacier in Los Glaciares National Park, part of the Southern Patagonian Ice Field, the third largest ice field in the world, on November 27, 2015 in Santa Cruz Province, Argentina. The majority of the almost 50 large glaciers in Los Glacieres National Park have been retreating during the past fifty years due to warming temperatures, according to the European Space Agency (ESA). The United States Geological Survey (USGS) reports that over 68 percent of the world's freshwater supplies are locked in ice caps and glaciers.

BUKIMA, VIRUNGA NATIONAL PARK, DRC, 6 AUGUST 2013: Images of the Bageni family in the gorilla sector of Virunga National Park, DRC, 6 August 2013. The gorillas sector is currently occupied by the M23 rebel movement of the Congolese army. Despite this and a previous occupation by a previous rebel group, the gorillas continue to survive, largely due the efforts of the ICCn, the Congolese Conservation Authority. The previous Bukima camps were destroyed, first by the CNDP rebel movement in 2008 and 2009; now most recently by their followers, the M23 rebels. Despite these setbacks and the ongoing danger, the ICCN Congolese conservation rangers continue to protect the mountain gorillas of the region and to plan for tourism which will follow if peace is achieved.
