“Carbon emissions and climate: Where do we stand, and what can be done if it all goes wrong?”

On Sunday, 11th February 2018, I presented an Abstract of a 3 hour talk on the subject, “Carbon emissions and climate: Where do we stand, and what can be done if it all goes wrong?” at the Needham Lyceum, hosted … Continue reading

What’s going on in the ocean off the Northeast United States

Hint: Climate change has somethin’ to do with it. Schematic diagram illustrating the component parts of the AMOC and the 26◦ N observing system. Black arrows represent the Ekman transport (predominantly northward). Red arrows illustrate the circulation of warm waters … Continue reading

Going down to the Southern Ocean, by Earle Wilson (on the Scripps R/V Roger Revelle)

(Click on picture to see a larger image, and use your browser Back button to return to reading.) Getting steady data from the Earth’s oceans demands commitment and not a little courage. I could never do what these oceanographers do, … Continue reading

Phytoplankton-delineated oceanic eddies near Antarctica

Excerpt, from NASA: Phytoplankton are the grass of the sea. They are floating, drifting, plant-like organisms that harness the energy of the Sun, mix it with carbon dioxide that they take from the atmosphere, and turn it into carbohydrates and … Continue reading

After the Decade of Dithering, the Deadly Twenties

In a recent post, after reviewing the extreme Arctic warming event of late 2015, Professor John Baez quotes an earlier interview with Dr Gregory Benford, who is arguing for a geoengineering effort to restore the frozen Arctic. I do not … Continue reading
