A sketch of the founding father of global warming science, Charles Keeling, in today’s NY Times. As a young man he was the first to figure out how to measure the amount of CO2 in the atmosphere.  It was 310 parts per million (ppm).  The year he died, 2005, it had risen to 380 ppm.

The temperature of the air and the ocean, averaged over the world, is following this rise.

At midnight Mauna Loa time, the carbon dioxide level hit 390 — and rising.
