planet in peril

The technical definition of a recession is a time period when a country's gross domestic product (GDP) doesn't grow, and doesn't stay flat, but actually shrinks. The thing is, at this point, we can roughly measure GDP not just for individual countries, but for the whole planet as well. Call it gross planet product (GPP). And according to a new analysis of international data, GPP shrank by 4.9 percent in 2015:

The last time we had a drop that big was with the Great Recession in 2008, when GPP contracted 5.3 percent. There have been a few other global recessions in the last 35 years, but other than a 2 percent drop in 1982, they've all been a fraction of a percent.

Arguably, a big part of the story here is that fact that the countries of the advanced world — America, Europe, and other developed nations — have been bouncing along at minimal growth, or dipping occasionally back into recession, ever since 2008. Poorer and less developed countries obviously can't take up much of the slack once the advanced world's economic engines slow down. The global downturn also adds to the possibility of a coming recession within America's borders, as well. Jeff Spross

According to new climate data, the West Antarctic ice sheet has begun to gradually melt, with potentially earth-changing results. Discovery reports that if the glaciers in the area melt completely, it could cause a massive "destabilizing effect" that could raise the earth's sea level by as much as 13 feet.

"Today we present observational evidence that the [ice sheet] has gone into irreversible retreat," said Jean Rignot, the author of a study published in Geophysical Research Letters. "It has reached the point of no return." The ice sheet, which consists of several glaciers, shows that the Thwaites Glacier is shedding several meters of ice elevation every year.

While scientists predict the glaciers won't be completely melted for another 200 to 900 years, their gradual retreat will have significant effects on the environment long before then. Jordan Valinsky
