Climate

I got drawn into climate science because of it's overlap with astronomy. For example, the pacing of ice ages is determined by changes in Earth's orbit, which in turn gives scientists a record of known changes in Earth's energy budget that can be used to assess how Earth's climate responds to disturbances. After studying climate science and realizing how little I know, I was appalled by how many people in the US disparage climate science while knowing much less than I did. Thus, I started sharing my learning as a test of myself and as teaching aids to those who are interested.

Climatology

The science of climatology is well founded in astronomy. To the right are illustrations and presentations that reside in the overlap between these fields.

Below is a graph showing Earth's orbit parameters, incident solar radiation at a few latitudes, levels of the greenhouse gases CO2 and CH4, and temperatures relative to a 1970-2000 baseline. Click the range bars (in white) on the timeline or drag the sliders to examine time periods.Click any graph to bring it to the front. Hover over a data point to read its value. Click a vertical scale marker (when displayed) to pin it; click again to remove it. (See bottom of page for revision notes.
