Global Warming

A new study has recently been published that looks at the ecology of bristlecone pine growth at Sheep Mountain, and the tree ring signal those trees produce, at high altitudes in the Southwestern US. This is important because tree rings are an often used proxyindicator for reconstructing past climates. Those who keep track of the…

2014 may be the warmest year on record

In early December I wrote a post called “2014 will not be the warmest year on record, but global warming is still real.” The very first thing I said in that post is that I was going out on a limb. I also discussed whether or not one year mattered, and I discussed the nature…

Matt Ridley is a British journalist whom some in the science community are now quietly referring to as an “anti-science writer.” He has taken up the cause of denying the widely held and deep scientific consensus on climate change. He has a recent blog post he seems to have been compelled to write in response…

The Road to Paris is a web site created by the ICSU, “…a non-governmental organization representing a global membership that includes both national scientific bodies (121 National Members representing 141 countries) and International Scientific Unions (30 Members),” founded in 1931. If the ICSU had not existed when the UN was formed, the UN would have…

I’m going out on a limb here. 2014 has been a very warm year. We’ve had a number of record setting months. But, a couple of months were also coolish, and November was one of them. December started out cool (like November ended) globally, but actually over the last few days the global average temperature…

Watch as documentary filmmaker Vanessa Black visits the Gulf of Mexico to learn more about Big Oil.

The term “Polar Vortex” was thrown around a lot last year, in reference to the persistent mass of very cold air that enveloped much of southern Canada and the US. As you will remember, Rush Limbaugh accused climate scientists and librul meteorologists of making up the polar vortex to scare everyone into thinking climate change…

Global Warming Means More Lightning

A new study just out in Science suggests that we will have an increase in lightning strikes of about 12 percent for every degree C of global warming. That could add up. From the abstract: Lightning plays an important role in atmospheric chemistry and in the initiation of wildfires, but the impact of global warming…

Warmest October On Record GISS NASA

The data for October has just been added to the NOAA GISS instrument record, which runs from 1880 to the present. October was the warmest on record, just beating out 2005. Overall, it is looking increasingly likely that 2014 will tie or beat the record for warmest year in the instrumental record, in terms of…
