Evan Bush

Evan Bush is a science journalist at NBC News who covers climate change and the environment through the lens of hard science and its impact on daily life. His reporting stands out for connecting technical research, government rules and long-term risks to concrete questions such as whether a home is safe after a wildfire or how a flood map shapes a neighborhood. He builds stories around recent scientific findings, the measures taken to address climate change and the ways communities adapt, rather than around isolated weather events.

Wildfire contamination and when a home is safe

Bush devotes significant attention to fire, but his work does not stop at flames or acreage burned; it tracks the toxic legacy that follows and the systems meant to manage it. In one investigation into the aftermath of fires near Los Angeles, he reports on contamination from heavy metals and other pollutants, detailing how burn patterns, debris and testing regimes determine whether properties can be cleaned or must be abandoned. He follows that thread into policy, covering California legislation that creates the first smoke contamination standards for homes after wildfires and explaining what regulators consider acceptable exposure before people move back in. In his coverage of giant, out-of-control fires in France and Spain, he ties fire behavior to climate-driven changes in heat and drought, showing how ecosystems, firefighting capacity and land-use decisions are being pushed into a new era of risk. Across these pieces, he uses expert interviews, on-the-ground examples and regulatory language to spell out how fire transforms landscapes, housing stock and public health far beyond the initial emergency.

Flood maps, property risk and living under water

Bush approaches flooding as a story about information and incentives as much as rainfall. In his reporting on FEMA’s outdated flood maps, he describes how properties are legally treated as lower risk than they are, and how owners use engineering analyses to challenge designations and avoid insurance or construction limits.

He highlights specific cases where new surveying changes a property’s status, showing how map revisions alter whether a family must carry flood insurance or can rebuild as they did before. The coverage brings technical cartography and federal bureaucracy down to the level of individual lots and mortgages, illustrating how climate-driven changes in precipitation collide with static maps and financial systems.

His framing makes clear that climate risk is embedded in paperwork and property records as much as in storm forecasts.

Explaining climate science, from El Niño to new species

Bush regularly uses new studies as the backbone of his stories, translating dense scientific work into plain narratives about changing conditions.

In his coverage of research finding that El Niño has become more intense because of climate change, he walks through long-running debates over whether the pattern is natural or human influenced and then explains how the new evidence shifts that discussion. He shows how changes in El Niño affect storms, temperatures and everyday weather, grounding abstract ocean processes in familiar consequences. In another piece, he reports on the identification of a new wild cat species for the first time in a century, outlining how researchers distinguished it from related species and why that matters for conservation and ecology.

These stories reflect his stated mission to communicate the latest scientific findings and explore their practical implications, whether the subject is atmospheric oscillations or hidden biodiversity.

Policy, politics and the fight over climate information

Bush’s work often sits at the intersection of science and power, tracking how political decisions shape what information reaches the public and how it is used. He has reported on climate scientists who were fired from a federal assessment and later stepped in to produce an independent collection of findings, explaining how their work was meant to fill a gap in official reporting.

In covering the Environmental Protection Agency’s rollback of emissions limits for coal- and gas-fired power plants, he connects regulatory language to expected changes in pollution and climate outcomes.

He also examines how misinformation and conspiracy theories influence lawmaking, as in his piece on “chemtrails,” where he distinguishes fictional spraying narratives from real geoengineering proposals and documents bills that have been shaped by those beliefs. Across these stories, he treats climate policy as a product of both scientific evidence and contested narratives, showing how the credibility of experts, the structure of agencies and the beliefs of voters and legislators interact.

His broader beat includes environment and science reporting for other outlets before joining NBC News, giving him a long-running perspective on how institutions and communities respond to climate pressures over time.
