The United States has nearly 100,000 miles of coastline and much of it is at risk of flooding. But what that inundation looks like varies widely from place to place. From storm surges to land subsidence, the latest Backgrounder details the different types of flooding and the threats they pose to coastal communities, especially sea level cities.

Wildfire’s immensely destructive power is not just about what it burns. The smoke from more frequent fires, too, has real potential to harm human health, the new Backgrounder explains, releasing particulate matter, carbon monoxide, nitrogen oxides, sulfur oxides and worse. Learn more about the hazards and historical perspective, along with what journalists should tell their communities can be done.

It’s not just scientists who are being lost to the new administration’s extensive firings of federal workers. A Backgrounder Analysis argues it’s the science itself. It’s happening at the U.S. Environmental Protection Agency, but also across agencies that conduct research to protect health and the environment, whether around toxic chemicals or on the battleground of climate change science. A frank look at the reality and what’s being lost for journalists and the communities they serve.

The judiciary is looking to become a major environmental battleground for journalists to watch in the coming months and years, as activists confront the Trump administration over its deregulatory campaign.

Anti-science policies are being instituted by the Trump administration at the U.S. Environmental Protection Agency and other federal offices, reports the latest Backgrounder. That makes it especially challenging to keep politics out of decision-making around everything from natural disasters to public health.

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.
