Ice was the same thickness in 1958 as today, and “steadily thinning.”

Arctic Ocean is ice free during ice ages. This is plausible. We know that the Bering Strait was ice free when people crossed from Asia to North America.

This is what I have been saying. In situ melt is not the cause Arctic ice loss over the last 20 years. The whole summer extent game is a mindless distraction.

Rising sea levels trigger ice ages

Scripps used to do actual climate science!
