shifting baselines – Southern Fried Science

Deep-sea gator falls covered in isopods, more struggles for the Ocean Cleanup, a robot lost in the cold (but not the one you’re thinking of), and more! Monday Morning Salvage: February 18, 2019

Flotsam (what we’re obsessed with right now)

What do you do if you find yourself at the helm of a major Louisiana marine science institution? If you’re Dr. Craig McClain, you plant the first experimental Alligator falls in the deep Gulf of Mexico!

On the other hand, if you find yourself at the helm of a US Navy destroyer, you might want to review this incredible and exhaustive accounting of the USS Fitzgerald disaster and how training deficits, exhaustion, and poor decision making compounded to create a deadly situation.

Fog Horn (A Call to Action)

Hurricane Harvey has passed, but its impacts will continue to be felt for years to come. There’s lots of great organizations to donate to, but in the immediate aftermath,it’s often best to donate to local relief programs that already have a ground team in place, rather than national groups that will take weeks to build up their infrastructure. I’m a fan of the Texas Diaper Bank and Portlight Inclusive Disaster Strategies, both of which serve communities that tend to be particularly vulnerable during natural disasters.

Flotsam (what we’re obsessed with right now)

It will take months, if not years, to fully understand the impacts of Hurricane Harvey, which already looks to be the costliest storm in US history. These drone videos give you some idea of the sheer scale of the damage. The Washington Post has an interactive map to help visualize what the equivalent deluge would look like around the world: What the Harvey deluge would look like where you live.

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

Science

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?
