Seth Borenstein

Seth Borenstein is a national science writer at The Associated Press who covers climate change, extreme weather, disasters and the physics behind them. His reporting is distinguished by a tight focus on what scientific findings mean for people, infrastructure and policy, translating complex climate and technology research into clear, consequence‑driven stories. He connects global diagnostics of Earth’s condition with granular accounts of hurricanes, heat waves, droughts and wildfires, often quantifying risk in terms that are easy to grasp. He has covered science and the environment for decades, including work on hurricanes, space shuttle accidents and long‑running climate impacts.

The new abnormal of climate extremes

Borenstein returns repeatedly to the theme of climate‑driven extremes, treating them as a “new abnormal” rather than isolated events. His coverage of deadly heat waves links rising temperatures and humidity with public‑health data, grid strain and the expanding reliance on air conditioning to save lives. He reports on hurricanes and tropical cyclones with an emphasis on measurable impacts, such as trillions of gallons of rain dumped on regions like the U.S. Southeast in a single week and the number of people exposed to high flood risk along Atlantic and Gulf coasts.

Wildfire coverage in his work traces how climate change alters fire behavior, including longer burning periods at night and more intense events in regions traditionally seen as less vulnerable. Drought and marine heat waves appear as part of the same pattern, with stories that tie record dryness and ocean warmth to food prices, water supply concerns and “supercharged” hurricane damage.

Across these pieces, he consistently anchors climate science in concrete metrics - rainfall totals, burn times, exposure counts - that underscore the scale of change.

Earth’s worsening environmental ills

A second strand in Borenstein’s work examines broad assessments of Earth’s health, often through major international reports and landmark studies. He has described the planet as “really quite sick now” and in a danger zone across most ecological dimensions, summarizing research that spans biodiversity loss, pollution, climate stress and human mortality.

His coverage of United Nations environment reports highlights how multiple environmental crises interact, emphasizing that millions of people die each year from worsening air, water and climate‑related hazards even as experts maintain that the situation is not hopeless.

In writing about the Anthropocene epoch, he explains how mid‑20th‑century human activity created a distinct geological era, using clear language to walk readers through concepts like stratigraphic markers and global signals of human impact. He also reaches back into deep time with stories on topics such as how changes in Earth’s rotation and longer days may have helped kick‑start oxygen development, showing a willingness to connect present‑day concerns with fundamental questions about planetary history.

These pieces combine accessible explanation with a sober view of cumulative damage, reinforcing his tendency to frame environmental issues as systemic rather than episodic.

AI, energy and the climate footprint

Borenstein has carved out a distinctive niche at the intersection of climate, energy systems and digital technology.

His reporting on artificial intelligence and data centers quantifies their environmental footprint, detailing electricity use that rivals large countries, associated carbon emissions and the trillions of gallons of water consumed to keep servers cool. He shows how rapid growth in AI could double these impacts within a few years, projecting data‑center energy demand to account for a notable share of global electricity use by 2030. In companion coverage, he breaks down how everyday online queries and AI applications add to individual and collective climate burdens, then explores practical steps people and institutions can take to reduce that footprint.

During high‑profile climate weeks and global gatherings, his stories frame AI and renewables together as a paradox - technology that can both worsen and help solve environmental problems - capturing the tension that policymakers and businesses face. This line of work is characterized by precise numbers, clear explanations of technical reports and a steady focus on how invisible digital infrastructure translates into real‑world emissions and water stress.

Hurricanes, wildfires and a long‑running science beat

Beyond his recent climate‑technology coverage, Borenstein maintains a broad disaster and risk beat that reflects years of specialized reporting.

His stories for news and insurance audiences delve into Atlantic hurricane seasons, explaining how phenomena like El Niño can suppress or intensify storms and what that means for coastal communities and insurers. He writes on flood‑risk studies that identify tens of millions of Americans at the highest risk along the Atlantic and Gulf coasts, translating technical mapping into clear takeaways about exposure and preparedness.

Wildfire pieces examine both the physical science - how warming and changing wind patterns lengthen burn times - and the practical side, including testing of home designs and construction standards to improve resilience.

Over his career he has also covered space and physics, including being part of a team recognized as a Pulitzer Prize finalist for reporting on the Columbia space shuttle disaster, and has received major awards for environment beat reporting from national journalism organizations and environmental journalism societies. Taken together, his output shows a reporter comfortable moving from field‑level disaster scenes to high‑level science and policy, with consistent attention to how evidence translates into risk and response.
