Greenhouse Gas Regulation

If you ask Americans who pay attention to climate change what they think about our climate policy, it is more than likely that you will get opinions about the 2022 Inflation Reduction Act. The IRA gets a lot of press for the very good reason that it is by far the most far-reaching law Congress … Read more

State of the Climate

Greetings! Belated Happy New Year to all, and welcome back to Earthward for 2024. We said goodbye to 2023 on an optimistic note – an unprecedented pledge at the UN’s December COP28 meeting calling for a “transition away” from fossil fuel energy, and new leadership from the US and China that produced a resolution for … Read more

COP28

As the hoopla around the latest annual UN climate summit begins to die down, it seems appropriate for healthy climate advocates to set aside a moment to ponder what just happened. The long runup to the 28th meeting of the Conference of the Parties (COP28), and the two-week meeting itself, generated some clear breakthroughs yet … Read more

Carbon Dioxide Pipelines

This Fall, the Oregon Department of Environmental Quality released an apparently routine notice requesting comments on a proposal to sell ethanol into the state. Like everywhere in the US, almost all commercial gasoline in Oregon is blended with 10-15% ethanol to raise the octane level and (according to the Department of Energy) improve “drivability.” The … Read more

Ocean Iron Fertilization

In the past few years, industrial-scale atmospheric carbon removal has moved from the fringes of respectable discourse to a mainstream part of the climate policy conversation. The 2022 Inflation Reduction Act, with its tax credits of up to $180 per ton for directly captured and safely sequestered carbon dioxide, was a key driver of this … Read more

White Gold

All eyes in the climate world are preparing to turn toward the UN’s annual two-week Conference of the Parties, which begins on November 30 in Dubai. This is the 28th such meeting under the 1992 international treaty known as the United Nations Framework Convention on Climate Change, which coordinates the worldwide response to global warming. … Read more

Ice Melt

Accelerated melting of sea ice, glaciers and ice sheets is among the most immediate consequences of global warming. An important benchmark for assessing these changes came two years ago, when the Intergovernmental Panel on Climate Change offered its latest synthesis of observations and computer modeling  on how melting of Earth’s ice (the cryosphere) may progress … Read more

Green Finance

Transitioning from fossil fuels to renewable energy requires mobilizing large amounts of money. This is a basic principle that has been executed with remarkable efficiency by the Biden administration. Within nineteen months of taking office, and with a unified Democratic Congress behind him, President Biden signed three major pieces of legislation that have greatly accelerated … Read more

Green Growth?

Earlier this month, the Executive Director of the International Energy Agency, Fatih Birol, made a provocative statement to accompany release of the agency’s latest World Energy Outlook, perhaps the most comprehensive analysis of the state of the global energy system and where it is heading. Looking at the data, Dr. Birol concluded that “…the transition … Read more

Methane Capture

International concern is growing over the rising level of atmospheric methane, a greenhouse gas second in influence only to carbon dioxide, and responsible for 25-30% of global warming since the start of the Industrial Revolution. Methane is a naturally occurring trace gas in Earth’s atmosphere that was present at a preindustrial concentration of 700 parts … Read more
