Corals are ocean-dwelling invertebrates in the same phylum as jellyfish. Corals are tiny and create an exoskeleton that is fixed to something hard, like the remains of previously existing corals. So these organisms build up a geological stratum, a reef, beneath the surface of the sea, often close enough that parts of the reef are…

Calling U.S. K-12 Science Education Professionals! GHF Online science instructor Madeline Goodwin is doing her Master’s thesis research on climate science in the classroom, and she needs your help! She is doing a survey of science education professionals to find the answer to the following question: What are the most important climate science concepts for…

There is a new study out in Nature that is liable to be misinterpreted, or that may be flawed in a way that lends itself to misuse, in the context of climate science driven policy. The study is “Northern Hemisphere hydroclimate variability over the past twelve centuries” by Fredrik Charpentier Ljungqvist, Paul J. Krusic, Hanna…

An Nasty Surprise in the Greenhouse

Climate Change: A Wicked Problem: Complexity and Uncertainty at the Intersection of Science, Economics, Politics, and Human Behavior, by Frank Incropera, is a textbook suitable for use in advanced high school or college classes, but also an excellent primer on the topic for anyone interested in it. Incropera spares little details in describing how the…

There wasn’t a “pause” in global warming. The rate at which the plant’s surface warms because of human greenhouse gas pollution varies over time. Sometimes the warming is quicker, sometimes it is slower. There are multiple reasons for a temporary slowdown in the temerature curve, including the temperature curve being a little inaccurate, the ocean…

The latest episode of Ikonokast, the science podcast Mike Haubrich and I do, is now up. This is an interview with Pacific Institute’s Peter Gleick.
