Black Carbon, 3 Billion Strong

I have been blogging about climate solutions and barriers to implementation and scale. Among the most important solutions are those that address short lived climate pollutants, primarily methane, black carbon, and HFCs, because if we stop or sequester those emissions, they will disappear from the atmosphere relatively quickly, unlike CO2. According to the UN Climate […]

Uncovering the Origins of False Claims in the Solar Geoengineering Discourse

ISO, the International Organization for Standardization

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.

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 – that are repeated until they acquire a […]

Weaponizing Water in Kashmir

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 […]

Capturing Methane — Agricultural Waste and Landfills

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 […]

The World’s Looming Water Crisis

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 […]

Helter Skelter

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 […]

Methane From Oil and Gas Operations, Update

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 […]

Too Many Climate Solutions

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 […]

Is the Amazon Burning?

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, […]

Trump Administration Attempts to Eviscerate the Endangered Species Act

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 […]
