It ain’t going to be easy, but it isn’t over yet and none of us have earned the right to quit. What genuine, no-bullshit ambition on climate change would look like.

Bone-eating zombie worms, octopus overlords, old wooden ships and new woes for deep-sea mining. It’s the Monday Morning Salvage! January 1, 2018.

Fog Horn (A Call to Action)

Stop. Breathe. Take a step back. This can all be incredibly overwhelming. Pick the fight that matters most to you and take a few days deciding what success looks like, what strategies will work, and what tactics are available to you. And then hoist your flag and get to work.

And when you meet someone fighting a different fight, remember to support them. There are already enough fronts to advance without taking friendly fire from our flanks.

Abnormal is the New Normal: Shifting Baselines, Polar Vortices, and Climate Change

Posted on January 24, 2014 by Andrew Thaler

The Polar Vortex, a mass of cold air usually centered around points within the Arctic Circle, made a visit south for the second time in 2014. The Vortex brings freezing weather, snow, and ice to regions that are unaccustomed to such extreme conditions. It also brings with it a new spate of “so much for global warming” talking-points, fresh on the heals of a recent report revealing that Climate Change Denial is at an all time high.

Unfortunately for the climate change denial industry, Polar Vortices are well-understood atmospheric phenomena. They were documented as early as 1853 as currents of cold air that essentially circle the poles. High-altitude observations in the 1950’s revealed the occurrence of sudden stratospheric warming (SSW) in the Arctic Polar Vortex. These SSW’s can cause a the vortex to weaken or reverse directions, allowing it to drift off axis or split into several smaller vortices. When weakened vortices contact the jet stream, cold arctic air is forced south, resulting in anomalously cold temperatures.

The obvious next question is: Is the weakened polar vortex caused by climate change?
