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)…

Let me start off by saying something you may not know. The big corporations and the 1%ers you have learned to hate fund many of the projects you’ve learned to love. I have not checked lately, but Murdoch and FOX corporation for several years in a row funded at a 50% or 60% level virtually…

Antarctica is pretty much covered with glaciers. Glaciers are dynamic entities that, unless they are in full melt, tend to grow near their thickest parts (that’s why those are the thickest parts) and mush outwards towards the edges, where the liminal areas either melt (usually seasonally) in situ or drop off into the sea. Antarctic’s…

A paper just out now in PNAS by Noah Diffenbaugh, Daniel Swain, and Danielle Touma shows that “Anthropogenic warming has increased drought risk in California.” From the abstract: … We find that although there has not been a substantial change in the probability of either negative or moderately negative precipitation anomalies in recent decades, the…

Climate scientists have noticed a disturbing pattern in the North Atlantic. This is the relative cooling of surface waters in the area fed by the Gulf Stream. This pattern has emerged over recent decades, and may portend very rapid and potentially disruptive climate change in the upcoming decades. The cooling is not subtle at all,…

And by “Shut. Up.” I mean shut up about whether or not global warming is real. The National Climatic Data Center of NOAA has just released the number representing the Earth’s surface temperature for February and it is a shocking 0.82 degrees C above the 20th century average. This is the second warmest Feb on…

The NASA GISS data for surface temperatures of the planet Earth are in for February, and February was warm. The anomaly value was 79, which means 0.79 degrees C above a the baseline NASA uses (1951-1980). So, while it looks like the planet has warmed by a about 8 tenths of a degree, since warming…

Human caused greenhouse gas pollution has warmed the planet. Global warming means more extreme weather. Many meteorologist who watch the weather every day see this. More and more research shows that greenhouse gas pollution changes the weather in a way that causes even more change in the weather. Changing weather systems means more lightning, increased…
