The New Climate "Normal": Abrupt Sea Level Rise and Predictions of Civilization Collapse

We know things are a bit "off" when a rainforest is on fire.

Over 400 acres of the Queets Rainforest, located in Olympic National Park in Washington State, nearby where I live, have burned recently, and it is continuing to burn as I type this. Fires in these rainforests have historically been rare, as the area typically receives in excess of 200 inches of rain annually.

But this is all changing now.

The new normal is that there is no longer any "normal."

The new normal regarding climate disruption is that, for the planet, today is better than tomorrow.
Another perfect example of this is a crucial recent study led by James Hansen, the former director of NASA's Goddard Institute for Space Studies. The study, authored by Hansen and more than a dozen other scientists and published online, warns that even staying within the internationally agreed goal of keeping the planet within the 2-degree Celsius temperature warming limit has already caused unstoppable melting in the Antarctic and Greenland ice sheets. The study shows that this will raise global sea levels by as much as 10 feet by the year 2050, inundating numerous major coastal cities with seawater.

As if that's not enough, Hansen's study comes on the heels of another study published in Science, which shows that global sea levels could rise by at least 20 feet, even if governments manage to keep global temperature increases to within the agreed upon "safe" limit of 2 degrees Celsius. The study warns that it is quite possible that 75 feet of sea level rise could well already be unstoppable given current carbon dioxide levels in the atmosphere and recent studies that show how rapidly Greenland and several Antarctic ice sheets are melting.

Disconcertingly, another new "normal" this month comes in the form of huge plumes of wildfire smoke over the Arctic. At the time of this writing, well over 12 million acres of forest and tundra in Canada and Alaska have burned in wildfires, and the smoke covering the Arctic sea ice is yet another anthropogenic climate disruption (ACD) amplifying feedback loop that will accelerate melting there. The additional smoke further warms the atmosphere that quickens the melting of the Arctic ice pack.
