New confirmation of the broad CO2 sensitivity factor. A fundamental tenet of climate science leads to the expectation that higher levels of atmospheric CO2 will over time be reflected in higher surface temperatures, and the reverse. This has been well-demonstrated during the past 800,000 years of ice ages. Now there is new research showing that the relationship holds up just as well for several million earlier years, when temperatures were mostly warmer, in all cases subject to a number of other variables and their calculated effects. This new evidence builds confidence in the basis of future predictions.

A new approach to capturing CO2 emissions. This is considered far superior to current technology, which has so far not proven to be practical. This article says nothing about how the captured gases are to be stored, which has also met up with experimental problems. The new method does offer a ray of hope for the concept of clean coal being realized.
(Here is a report published two weeks ago explaining some of the difficulties found on the sequestration end, that still need to be resolved.)

A fascinating discovery. From Northwestern University, a new way to convert nitrogen into amonia using solar energy. It could eventually replace the Haber-Bosch process, which presently consumes more than 1 percent of the world’s energy supply. Much further development work will be required to justify commercial interest.

An interview with Paul Ehrlich. Paul Ehrlich has been studying the Earth and its ecology intensely for over half a century. He is familiar with all the other senior scientists around the world who are likewise engaged. His views on climate change are well-considered and surely worth one’s attention. This should help you decide whether the subject is really something for the current generation to take seriously. (Be patient while the video loads.)
