On Feb. 3, 2023, a train carrying chemicals jumped the tracks in East Palestine, Ohio, rupturing railcars filled with hazardous materials and fueling chemical fires at the foothills of the Appalachian Mountains. The disaster drew global attention as the governors of Ohio and Pennsylvania urged evacuations for a mile around the site. Flames and smoke billowed from burning chemicals, and an acrid odor radiated from the derailment area as chemicals entered the air and spilled into a nearby creek. Three days later, at the urging of the rail company, Norfolk Southern, about 1 million pounds of vinyl chloride, a chemical that can be toxic to humans at high doses, was released from the damaged train cars and set aflame. Federal investigators later concluded that the open burn and the black mushroom cloud it produced were unnecessary, but it was too late. Railcar chemicals spread into Ohio and Pennsylvania. The scene after a train carrying haz...

The heat dome that descended upon the Pacific Northwest in late June 2021 met a population radically unprepared for it. Almost two-thirds of households earning US$50,000 or less and 70% of rented houses in Washington’s King, Pierce and Snohomish counties had no air conditioning. In Spokane, nearly one-quarter of survey respondents didn’t have in-home air conditioning, and among those who did, 1 in 5 faced significant, often financial, barriers to using it. Imagine having no way to cool your home as temperatures spiked to 108 degrees Fahrenheit (43 Celsius), and 120 F (49 C) in some places. People in urban heat islands – areas with few trees and lots of asphalt and concrete that can absorb and radiate heat – saw temperatures as much as 14 F (7.8 C) higher than that. Extreme heat disasters like this are becoming increasingly common in regions where high heat used to be rare. Blackouts during severe heat waves can also leave residents who believe they are...

Fossil fuels are the leading driver of climate change, yet they are still heavily subsidized by governments around the world. Although many countries have explicitly promised to reduce fossil fuel subsidies to combat climate change, this has proven difficult to accomplish. As a result, fossil fuels remain relatively inexpensive, and their use and greenhouse gas emissions continue to grow. I work in environmental and energy law and have studied the fossil fuel sector for years. Here’s how fossil fuel subsidies work and why they’re so stubborn. What is a subsidy? A subsidy is a financial benefit given by a government to an entity or industry. Some subsidies are relatively obvious, such as publicly funded crop insurance or research grants to help pharmaceutical companies develop new drugs. Others are less visible. A tariff on an imported product, for example, can subsidize domestic manufacturers of that product. More controversially, some would argue that when a gov...
