There was a time when I picked which local TV news station to watch based on the way the TV meteorologist addressed global warming. There were two stations in the running. One of them had a guy who frequently disparaged climate science, and the other had Paul Douglas, who no longer does TV meteorology (I…

March 2015 Was A Very Warm Month

The last 12 months have been the warmest one year period in the NASA database since records began in 1880. According to the just released NASA GISS Global Temperature Data, March, 2015 is estimated to have been the fifth warmest month on record. Here are the top 20 months in rank order: 2007 JAN 93…

The number one rule of the Taphonomy Club is don’t talk about marks on bones … without placing them in context. Many marks on bones could have multiple causes, such as putative cut marks caused by stone tools on animal bones found on early hominid sites. In that case, hard sharp stony objects in the…

The rise of Skeptical Science

The site, not the thing. From the YouTube site: Everyone at Skeptical Science spends a lot of their time reading the scientific literature and listening to experts. Without that we wouldn’t be able to write all the material that’s published on Skeptical Science. It’s a lot of work, especially when you do this with a…

According to the best available research, we are going to have to double food supplies, globally, by 2050. Think about that for a moment. Children born today will be in their 40s at a time that we need to have already doubled food production, yet during the last 20 years we have seen only a…

Bully for Brontosaurus

Much is being made of Brontosaurus. Brontosaurus is a genus name for a large dinosaur, known to watchers of “Land Before Time” as “Long-Necks.” That generic name dates to the 19th century, but in the early 20th century it was eliminated as a proper Linnaean term and replaced with Apatosaurus. This made us sad. Most…

Developing The Waco Mammoth Site

I got a press release about the Waco Mammoth Site that I thought I’d pass on to you: National Park Service Director Jarvis Participates in Public Meeting about Waco Mammoth Site WACO, TX – Today, National Park Service Director Jonathan B. Jarvis heard from the citizens of Waco regarding the community’s vision to preserve, protect…

Maybe, maybe not. There is a new paper that looks at what climate scientists call “synoptic midlatitude temperature variability” and the rest of us call “cold snaps” and “heat waves.” The term “synoptic” simply means over a reasonably large area like you might expect a cold snap or heat wave to be. Specifically, the paper…

A new study by Sarah Moffitt, Tessa Hill, Peter Roopnarine, and James Kennett (Response of seafloor ecosystems to abrubt global climate change) gets a handle on the effects of relatively rapid warming and associated Oxygen loss in the sea on invertebrate communities. The study looked at a recent warming event (the end of the last…

There is some interesting new work carried out by researchers at Dartmouth College and the USDA Forest Service on the relationship between the Mountain Pine Beetle, major die-offs of forests in North America, and climate change. The Mountain Pine Beetle (Dendroctonus ponderosae) is a kind of “bark beetle” (they don’t bark, they live in bark)…
