A new study concerning the effect of higher CO2 levels on agricultural crop production. The main point is that the benefits due to increased photosynthesis can be negated by certain feedback effects that are commonly overlooked. This varies from region to region. Overall, “the modeling showed that plant life in most regions of the world suffers considerably due to rising temperatures and decreased precipitation.” Some of the specific details in the argument, based on work undertaken at Purdue University, are of especially unusual interest.

Small ponds are known to be a major source of natural methane emissions. What happens when they get warmer? Researchers in the UK have performed tests, and find that the rate of methane release accelerates. At the same time their ability to absorb CO2 from the air declines. The combined effect, “which could have serious impacts on climate change,” is presently not accounted for in IPCC models. (I wonder if the same point is meant to include reference to the substantial amount of methane released by rice paddies?)

Two well-known scientists speak out in praise of the way science is actually done, while deploring the methods of badly motivated politicians who try to undermine their work (from Scientific American). This conflict has suddenly risen to a crescendo in Washington. It is unclear how well the broad public understands the danger of what is happening, or how it will react. It should be emphasized that not all science is under attack right now, just the segment that is threatening to major financial powers.

The amazing progress being made by offshore wind. In Europe construction costs have fallen 46% in five years, and are now closing in on the cost of building new coal plants. (That’s before considering subsequent energy costs.) One big advantage of going offshore is that wind speeds are almost triple the average onshore speed. Offshore oil producers, having the right skills to deal with the harsh operating conditions, are getting more and more interested.
