A major new report on land degradation and the loss of biodiversity. This was issued by a scientific group backed by the UN, in many ways structured like the IPCC but without the longevity or level of publicity. The message is every bit as important as that of climate change and the two are closely related. I will give you two links to read, the first being more of an introduction and the second a copy of the press release that came directly from the organization following a major conference, loaded with vital information that everyone should know about along with concepts of mitigation addressed mainly to policymakers.

The amazing ability of “blue carbon” ecosystems to store carbon. “Blue carbon coastal ecosystems — such as mangroves, seagrass meadows and tidal wetlands — are named for their place at the boundary between land and sea, and their unmatched ability to suck CO2 out of the atmosphere and store it in the ground below.” They do so at a rate 4o times faster than land vegetation and keep it in place for thousands of years. Reversing the current trend of losses is a major challenge.

“Negative emissions” are clearly required to achieve climate goals. This article takes a look at the latest thinking from science about how this might be achieved. Natural approaches are very doable, relatively inexpensive and have many side benefits but somewhat limited in total opportunity. Technological approaches are still surrounded by questions but some that are in early stages of development are worth watching.

The US has the ability to meet 100% of its electric power needs with clean energy. That is the conclusion of a high-level science team. There is enough capacity of wind and solar resources to achieve 90% of that goal with the help of storage facilities while other options like hydro or nuclear can fill the remaining gap. Cost considerations should work in favor of this happening. They do not predict the timing.
–To be sure, there are still powerful forces at work seeking to keep fossil fuel suppliers in business as long as possible (VOX).
