The first person ever to catch Ebola in the United States is now in isolation at Texas Health Presbyterian Hospital. Don’t panic, even if you live in Dallas. But also, don’t fall into the hyperskeptical trap of assuming that because scientific authorities tell you everything is fine that concern is irrational. There are very rational…

According to those intimately involved in the response to the West African Ebola outbreak, NewLink Genetics owns the rights to a piece of the puzzle needed to quickly test and deploy one of two likely Ebola vaccines and they are holding up the entire process because they are not entirely sure they are going to…

Last June (and May and July and part of August) we had a lot of precipitation in Minnesota. This caused lake levels to rise modestly. One lake, which is large enough to have meaningful waves, has older settlement along it so lots of cabins, boat houses, and such are right on the shoreline. With the…

This is an endorsement by Climate Hawks Vote, which I support. Climate Hawks Vote announces endorsements of two Michigan Democrats: Paul Clements for Congress in Michigan’s Sixth District, and Gary Peters for Senate, because the Koch brothers and Big Oil need to stop using Michigan’s shores as a dumping ground for their pollution and Michigan’s…

Antarctic Sea Ice and Global Warming

Did you ever leave your freezer door slightly open on a humid day only to find chunks of new ice formed at the gap? When that happens, did you conclude “Oh, my freezer is colder than usual, I wonder how that happened?” No. You concluded that you had left the door slightly open, some cold…

This is an endorsement by Climate Hawks Vote, which I support. We’re working our way through scoring Senate Democrats on climate leadership, using the same lodestar that we’ve used on House Democrats: who’s leading on climate by engaging the public? It’s slow going – results might not be final until mid-October or later. However, given…

Shenna Bellows of Maine for Senate

This is an endorsement by Climate Hawks Vote, which I support. We’re endorsing climate hawk Shenna Bellows to be the next Senator from Maine because business as usual is no longer good enough in the face of a local and worldwide crisis. Long-time incumbent Susan Collins admits the existence of a problem, to her credit;…

UPDATE: They killed the dog. UPDATE: I’m adding this here because it is my current post on Ebola. Thomas Eric Duncan, the person who became symptomatic with Ebola in Dallas, had died at the Texas Health Presbyterian Hospital (according to news alerts). A nurse’s assistant in Spain caring for Spanish nationals returned with Ebola from…

What is the role of the ocean’s abyss in global warming?1 I’ve already posted on a study published in Nature Climate change that shows that the amount of extra global warming related heat in the Southern Oceans is greater than previously thought. There is another paper in the same journal by Llovel et al, “Deep-ocean…

You can listen to the interview here: Play Now I’d like to take this opportunity to thank Minnesota Atheists for giving me the opportunity to do these science…
