Is the answer to the democratization of Science doing more Citizen Science?
I have been following, with keen interest, the post and comment thread pertaining to “Democratising science” at the blog I monitor daily, … and Then There’s Physics. I think the core subject being discussed is a little different from my … Continue reading

The first really scary really stupid anti-science prospect from the Trumpistas
They want to shut down and defund DSCOVR: DSCOVR’s cameras are intended to monitor changes in earth’s climate and weather patterns, from ozone and aerosols to temperature and deforestation. One of the scientists involved in developing the satellite told Air … Continue reading

`Anecdotes don’t make reliable evidence’
From Katharine Hayhoe, who I deeply respect, and from John Cook (*), scientists and the quantitative community have been scolded that the reason they don’t make headway with the public and the science denier community is because their explanations are too … Continue reading

Absorption of long wave, or thermal radiation by CO2 at 667 per cm

On infrared radiation and Earth temperature
Good to review the basics once again. Professors Dave Archer and Ray Pierrehumbert do, in my opinion, some of the best introductions: Infrared radiation and planetary temperature.

Rabett Run reprises the Carbon Cycle … and very well, too
Eli condenses the problem with the Carbon Cycle and excessive emissions of fossil fuel CO2 to a few paragraphs, a great figure, and a trio of linear differential equations.
