Sea level changes in the Pacific Ocean are providing good predictions of global air temperatures. A fascinating new study demonstrates the accuracy of this strange connection, which basically depends on the way sea level in the Pacific tilts back and forth during El Nino/La Nina cycles. That allows the warmest waters to either pile up in depth or spread out over more of the surface, thus changing its exposure to the air above. By carefully measuring how that level swings one can predict air temperatures a whole year ahead! This will be of great help toward explaining the principal cause of observed variation in annual temperature cycles.

A critique of Bill McKibben’s war metaphor. This thoughtful piece makes a number of good points and raises valid questions about the effectiveness of brandishing the language of full mobilization, but doesn’t dispute the underlying need. Real mobilization requires the coming together of many diverse parties, which in this case must expand to take in much of the whole globe. For victory to be achieved the target is not simply the producers of fossil fuels but the consumers too, which includes almost all of us. It would not be so difficult if there were plenty of time. That option has already been taken away by the successful delaying tactics employed by the opposition, which are continuing to this day.

What James Hansen was predicting in 1981, and how things have actually turned out. That was 35 years ago, when the science was still quite new but obviously worth listening to. Today the science is much broader and stronger, and Hansen is still writing papers that carry messages no one wants to hear. Peter Sinclair’s video at the end is interesting.

Climate change clearly observed in one’s own time, within the lower 48 states. This happened while global temperatures, on average, were rising only about one-half degree C. Everywhere, more and more older people are reporting things in the natural world they have never before observed.
