Ripple effects all over the planet

Oh and by the way it’s speeding up.

Planet-warming pollution from burning fossil fuels and other human activities has already raised global temperatures more than 1.1 degrees Celsius (2 degrees Fahrenheit). But the effects are particularly profound at the poles, where rising temperatures have seriously undermined regions once locked in ice.

In research presented this week at the world’s biggest earth science conference, Pettit showed that the Thwaites ice shelf could collapse within the next three to five years, unleashing a river of ice that could dramatically raise sea levels. Aerial surveys document how warmer conditions have allowed beavers to invade the Arctic tundra, flooding the landscape with their dams. Large commercial ships are increasingly infiltrating formerly frozen areas, disturbing wildlife and generating disastrous amounts of trash.

The rapid transformation of the Arctic and Antarctic creates ripple effects all over the planet. Sea levels will rise, weather patterns will shift and ecosystems will be altered. Unless humanity acts swiftly to curb emissions, scientists say, the same forces that have destabilized the poles will wreak havoc on the rest of the globe.

There’s a lot more in the same vein. It’s all very bad news.
