The amount of heat stored in the ocean, as reflected by its temperature, is the ultimate driver of climate change. Estimates of global ocean temperature improved with remote measurement techniques in the mid 2000s (i.e., Argo Float program). There remains uncertainty about ocean temperatures in the 20th century, which leads to uncertainty about how quickly ocean temperatures climbed to their current levels. The faster the oceans warm due to increased greenhouse gas concentrations, the more quickly our climate will change and the faster impacts will be upon us.

The Washington Post reports on a study that concludes the ocean has absorbed heat at a rate near the highest end of the range of previous calculations. The new study uses a completely different technique for estimating temperature by measuring the outgassing of oxygen and carbon dioxide from the ocean (which are temperature dependent processes), and using those measurements to estimate the warming of the oceans. Testing a hypothesis using an independent line of evidence is one of the most powerful techniques available in science, which is one reason this study has received so much attention.

The fact that this study suggests ocean heat content is on the higher end of previous estimates is very important, as it suggests we have even less time to avoid the worst impacts of climate change…

Trump talks climate (uh-oh), a low-carbon food system, New York sues ExxonMobil, cactus, hummingbirds and climate change, hurricane intensification

In an interview with President Trump Lesley Stahl of 60 Minutes asked President Trump about climate change. As you might imagine, this did not go well. Trump asked Stahl to “show me the scientists [who conclude climate change is human-caused]…they have a very big political agenda.” He contradicted his previous statements by saying that climate change is not a hoax, “I think something’s happening. Something’s changing and it’ll change back again.” Boy, is that wrong, as I pointed in a letter published by the San Francisco Chronicle:

President Trump says our climate “will change back again,” showing a complete disregard for physical reality. Greenhouse gases emitted by humans are trapping on the planet heat that used to escape into outer space, and so the planet is getting warmer. There is no other credible explanation for what is happening. Our climate can no more “change back again” than a tea kettle on the flame can start cooling down on its own…
