New information about the world’s ecological footprint is available. It is still much too high, but there is some hope that it may have leveled off in recent years. Much new data has become available, subject of an overall review in this post. At the end there are links to websites that have additional materials suited to those who may have an active interest.

New ways to improve the efficiency of wind power. Researchers are using supercomputers “to filter out the effects of turbulence and apply control algorithms that can better manage the operation of wind farms. The approach has the potential to increase wind power generation by 6-7 percent.”

The monstrous scale of modern windmills depicted, inside and out (New York Times). You also get views of mass production facilities and output—just amazing.

A look at prospects for renewable heat. Renewable electricity is well on its way to fulfillment and renewable transportation is off to a good start but renewable heating has lagged behind. This post from Australia sees plenty of opportunity for that to change, especially for now in any region that has a mild climate.

Climate science: Why do air temperatures over the continents increase more rapidly than over the oceans? A simple answer to that question has been discovered, the main principle of which can be found by reading this post. For a more complete explanation I suggest that you open the link to the basic study, where the Abstract and a note about Significance are available. This is fascinating information, and I believe there are serious implications for how the picture of Earth’s future climate might evolve, perhaps requiring scientists to rethink their model forecasts. https://phys.org/news/2018-04-ocean-simple.html

Another study has interesting new information about the nature and consequences of an AMOC slowdown. Based on a strange complex of changes that were occurring 12,000 years ago it appears that a weaker AMOC might actually produce heat waves in Europe instead of a cooling effect. “This study has important implications for our ability to predict heat waves and drought in Europe, as the models we use for climate predictions strongly underestimate blocking circulation, and therefore may under-estimate the impact of a weaker AMOC on European climate and water resources.”
