How Hot Will Things Get?
Identifying a realistic worst case scenario is complicated.
How hot will the world be in 2100? The answer partly depends on how much carbon we dump in the atmosphere between now and then. It also depends on how sensitive the climate system is to those emissions. Scientists have used 4.5 °C as the high end of the likely possibilities. That estimate derives from …

The president’s embrace of massive tree planting has a remarkable — and questionable — backstory
During last week’s State of the Union address, US President Donald Trump said: To protect the environment, days ago I announced that the United States will join the One Trillion Trees Initiative, an ambitious effort to bring together government and private sector to plant new trees in America and all around the world. Astute regular …

Trump’s NEPA proposal flunks Torts as well as Environmental Science 101.
Last week’s NEPA proposal bars agencies from considering many of the harms their actions will produce, such as climate change. These restrictions profoundly misunderstand the nature of environmental problems and are based on the flimsiest of legal foundations. Specifically, the proposal tells agencies they do not need to consider environmental “effects if they are remote …

State and Local Governments’ Common Law-Based Lawsuits Against the Energy Industry Are Steadily Gaining Traction
The latest chapter in American climate change litigation has been launched by local governments–and one state–across the U.S. against domestic and international fossil fuel companies. These lawsuits have been brought under one of the oldest and most venerable legal doctrines–state common law. They seek compensation from the energy industry for the myriad, adverse effects of …

Reflections on Stopping Speeding Locomotives and Falling Off Cliffs
In my last post, I sketched a few of the many intense tensions and contradictions swirling around this year’s Conference of the Parties (COP25) to the UN Framework Convention on Climate Change (FCCC). In this post, I’ll try to make some sense of the biggest tension of all, one that folks working on climate are …

The Montreal Protocol offers lessons for climate change, but not a role model
In an extended piece yesterday, The New York Times editorial board wrote that “The World Solved the Ozone Problem. It Can Solve Climate Change. The same tools that fixed the ozone hole — science, innovation and international action — can address.” Although the editorial was mostly correct, it missed what I believe to be the …

EPA Cites an Inapplicable “Housekeeping Statute” to Justify Its Rule to Limit the Use of Science In Important Regulatory Decisions
Over a year ago, EPA issued a proposed rule , ostensibly to promote transparency in the use of science to inform regulation. The proposal, which mirrors failed legislation introduced multiple times in the House, has the potential to dramatically restrict EPA’s ability to rely on key scientific studies that underpin public health regulations. The rule, …

Surprise, surprise, EPA has tried to stonewall an investigation.
EPA’s Acting Inspector General Charles J. Sheehan took the extraordinary step last week of notifying Congress that EPA was stonewalling his investigation of potential misconduct involving EPA’s Chief of Staff. This was a gutsy move for Sheehan, especially given the extra vulnerability created by his Acting status. Sheehan, it is worth noting, is a career …

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 …

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 …
