Uncovering the Origins of False Claims in the Solar Geoengineering Discourse
The story behind a recent news article reveals how activist groups—with the media’s help—cause misleading and false assertions to arise, persist, and spread.
Originally posted at Harvard’s Solar Geoengineering Research Program. Much of my work concerns solar geoengineering, a set of proposals to block or reflect a small portion of incoming sunlight in order to reduce global warming. Unfortunately, the discourse is rife with specious, misrepresented, and outright false statements – many of which are consistent with intuition – …

India’s legal moves on water put Pakistan on edge
A month after India’s move to exert more direct control over Jammu & Kashmir, the Indian state that occupies part of the larger Kashmir region, the country is also now in a position to exert control – in both illegal and legal ways – over important river waters that Pakistan relies upon to sustain people …

Barriers to Solutions, continued
In California, over fifty percent of methane emissions come from the agriculture sector and over twenty percent from landfills. Most of the agriculture emissions come from manure and enteric fermentation, sometimes referred to as “cow burps.” As is the case with many sources of greenhouse gas emissions, there are many potential solutions for limiting and …

Climate Change Worsens Chronic Water Shortages for One-Quarter of Earth’s Population
The World Resources Institute recently released a disturbing report chronicling increased, dire water shortages around the globe that threaten millions of the earth’s inhabitants. Climate change is a major contributing factor. Public health crises, social unrest and global political conflicts are the inevitable consequences if the problem is not addressed successfully–and soon. “17 Countries, Home …

Even for deregulators, the latest rollback makes no sense.
The Washington Post reported this morning that EPA is getting ready to roll back yet another Obama Administration climate regulation — this time, one regulating natural gas leaks. I wanted to add a brief postscript to Ken Alex’s post on this. What struck me most immediately was the sheer economic weirdness of making this rollback …

Another Trump Rollback
A quick and depressing update to my post yesterday about methane emissions from oil and gas operations. According to the NY Times, the Trump administration “will aim to eliminate federal requirements that oil and gas companies install technology to inspect for and fix methane leaks from wells, pipelines and storage facilities.” This, to use a …

It’s all about implementation
It turns out that there are lots of very promising climate solutions. Drawdown, for example, provides an excellent list. Implementing those solutions – moving them to pilots, policy, and scale – remains very challenging, for a variety of reasons, some legal and regulatory, some political, economic, and technical. I have started Project Climate at the …

The current panic may not be justified, although long-term worries are
The environmental community is presently up in arms about fires in Brazil’s Amazon. The number of fires have dramatically increased over this time last year. A Greenpeace worker said, “This is not just a forest that is burning. This is almost a cemetery. Because all you can see is death.” France’s president Emmanuel Macron tweeted, …

Rather Than “Improve” ESA, Newly-Adopted Regulations Dramatically Erode Its Historic Protections
The Endangered Species Act, enacted in 1973, has for most of its history been the most controversial and politically-charged of all the foundational environmental laws adopted by Congress in the 1970’s. But despite its contentious history, opponents of the ESA have been unsuccessful in their efforts to weaken the law, either through significant Congressional amendments …

An innovative approach to ambitious goals
Last week, the Los Angeles County Board of Supervisors unanimously approved the LA Countywide Sustainability Plan. Along with my colleagues Sean Hecht and Nat Logar and other faculty across UCLA, I assisted in the drafting process and witnessed the shaping of the Plan from the ground up. The final Plan provides a best practices model …
