Can Soils Solve Climate Change?
Another dubious claim of natural climate solutions makes the rounds
A few months ago, I questioned a claim that planting trees could solve climate change. According to some scientists, reforestation “is by far the cheapest solution that has ever been proposed,” and for $300 billion it could sequester 200 gigatons of carbon (GtC, or 733 GtCO2). Many media outlets swooned, but the assertions were weak …

DOJ Sues the State for Its Cap-and-Trade Agreement with Quebec
The Trump attack on California’s climate policies has entered a new phase. In addition to revoking the state’s permission to regulate tailpipe emissions from cars, investigating auto makers for antitrust violations for cooperating with California on reducing car emissions, threatening to revoke highway funds from the state for Clean Air Act violations while simultaneously taking …

A brief report from a recent Emmett-convened event
As the severity of climate change risks and the inability of current efforts to adequately limit risks become clear, geoengineering technologies – active large-scale environmental interventions to reduce disruptions caused by elevated greenhouse gases – are increasingly receiving attention and generating controversy. These proposals would either remove and sequester atmospheric carbon dioxide or modify the …

Australia is leaping from the frying pan into the fire.
Australian climate politics has been strange if not chaotic. And in terms of climate policy, things seems to be going from bad to worse. This is partly a function of general political upheaval. In an enlightening 2018 paper, three University of Melbourne law professors (Baxter. Milligan, and McRae) traced the developments from 2007 to 2016. …

From California to Brazil, state and provinces around the world are stepping up to fight tropical deforestation. They need and deserve more support.
The fires burning in Brazil and the broader Amazon basin have shined a spotlight on the role of forests and land use in the climate change challenge. For the first time in many years, the fate of tropical forests and their connection to our common future have captured the public imagination around the world. There …

China and the United States are the two largest emitters of greenhouse gases in the world, accounting for some 45 percent of global emissions. The world is unlikely to find a solution to climate change without aggressive action from both. With the Trump administration retreating from climate action, U.S. states and cities are pushing to …

Welcoming a famous new faculty member and a critical new initiative.
I have two exciting announcements to make. The first is that Jerry Brown has accepted an appointment as visiting professor at the law school and the College of Natural Resources (CNR) at Berkeley. That appointment would be exciting enough. But it goes hand in hand with my other news: the public launch of the California-China …

New book explores natural capital policy and finance mechanisms from around the world
Since the Industrial Revolution, growth in human numbers and economic activity has dramatically transformed our planet. Rapid economic development has lifted hundreds of millions of people out of poverty and raised the standard of living and life expectancies of many more, but these forms of growth have also deeply eroded the natural capital embodied in …

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 …
