Whether fires in California or flooding in North Carolina, climate disasters are revealing a major fault line in U.S. emergency response — a serious insurance shortfall that may lead to financial catastrophe. The new Issue Backgrounder explores the risks of underinsured disasters, the limits to the national flood insurance programs and FEMA aid, and the predictable scapegoating that has created solution gridlock.

The displacement of populations by climate impacts, while not a new phenomenon in human history, is worsening in the face of global warming’s extreme weather patterns. Yet the extensive international regime to aid refugees doesn’t cover those migrating due to flooding, drought, natural disasters or climate change. Backgrounder considers the implications and how nations will respond to the new realities.

While Kamala Harris has provided little detail about what her environment and energy policies would be as president, her record has been enough to win her the quick support of most major environmental groups, finds the latest Issue Backgrounder. A look at her record on the Green New Deal and fracking, her presidential environmental platform and her contrasts with GOP rival Donald Trump.

If former President Donald Trump recaptures the White House this fall, it would likely bring back a radical deregulatory, climate change-oblivious, fossil fuel-intensive environmental policy. But could the fallout be even greater? The new Issue Backgrounder examines how the Project 2025 agenda of Trump’s allies takes aim, in particular, at the U.S. Environmental Protection Agency.

A major intergovernmental gathering later this year will address plastic pollution, including in oceans. But an overview from our Issue Backgrounder notes that the likelihood of solving the problem may be small. One reason? Petrochemical industry lobbying. Another? The shifting world market for plastic waste. And there are more concerns, such as the effectiveness of incineration and chemical recycling techniques. More, including questions to ask, in Backgrounder.

A new federal rule to cut power plant pollution and carbon dioxide emissions promises to escalate a yearslong, highly partisan battle at the core of U.S. climate change policy. Our Issue Backgrounder lays out the shifting regulatory approaches from the administrations of George W. Bush to Joe Biden, and notes the legal tug-of-war that has heightened the importance of another big player — the Supreme Court.

For all the talk about the energy transition and the robust growth in electric vehicle sales, there’s one big reason for unease: getting charged. The new Backgrounder takes a deep dive on the state of EV charging stations in the United States, exploring Tesla’s diminishing dominance, coming charger standardization, charging levels, software and for-pay realities, plus the effects of government policy.

A partisan debate has flared over liquified natural gas, as industry, environmentalists and politicians wrangle over LNG’s role in climate change and the energy transition, heating and electricity prices, and international and domestic U.S. politics. Backgrounder lays out LNG’s history, starting with the fracking boom and bringing it up to speed with the war in Ukraine and upcoming presidential elections.

A key U.S. federal agency tasked with investigating the nation’s industrial chemical accidents has been limping along for years. Now, the latest Issue Backgrounder reports that replenished staffing and a funding boost may mean it’s found its footing. But as the pace of chemical accidents accelerates and safety regulations stagnate, will it make a difference?

With the world in the midst of wars in Ukraine and the Gaza Strip, it’s time for journalists to appraise — and report on — the intersection of conflict and the environment, argues the new Backgrounder. That means considering the environment not only as a victim of war, but also as the cause of war and a means of carrying it out.
