Geoff Brumfiel

Geoff Brumfiel works as a senior editor and correspondent on NPR's science desk. His editing duties include climate and environment, while his reporting focuses on the intersection of science and national security.

From April of 2016 to September of 2018, Brumfiel served as an editor overseeing basic research and climate science. Prior to that, he worked for three years as a reporter covering physics and space for the network. Brumfiel has carried his microphone into ghost villages created by the Fukushima nuclear accident in Japan. He's tracked the journey of highly enriched uranium as it was shipped out of Poland. For a story on how animals drink, he crouched for over an hour and tried to convince his neighbor's cat to lap a bowl of milk.

Before NPR, Brumfiel was based in London as a senior reporter for Nature Magazine from 2007-2013. There, he covered energy, space, climate, and the physical sciences. From 2002 – 2007, Brumfiel was Nature Magazine's Washington Correspondent.

Brumfiel is the 2013 winner of the Association of British Science Writers award for news reporting on the Fukushima nuclear accident.

Satellite imagery suggests North Korea is preparing an intercontinental ballistic missile or satellite rocket launch at one of its test sites.

Satellite imagery suggests that North Korea may be taking steps to reactivate a partially decommissioned long-range rocket test site on the country's west coast.

North Korea's main nuclear reactor for making weapons-grade plutonium may be operating, just days before this week's summit between President Trump and North Korean leader Kim Jong Un.

When President Trump and North Korean leader Kim Jong Un discuss denuclearization in Hanoi, they are likely to focus on one North Korean nuclear facility in particular. NPR's Geoff Brumfiel introduces us to it.

Satellite imagery of a space launch center in northern Iran suggests a second attempt to launch a satellite has failed.

The imagery, taken Wednesday by San Francisco-based company Planet and shared with NPR, shows burn scars on a newly painted launchpad at the Imam Khomeini Space Center. The burns appeared after days of activity at the site, which suggested Iran had been preparing for a launch.

At a Russian base on the Baltic Sea, construction is underway to house a new generation of nuclear-capable missiles.

Tentlike structures have popped up to shelter the mobile missile system, known as Iskander, which is capable of firing weapons with both conventional and nuclear warheads. Recent satellite imagery of the territory, known as Kaliningrad, also shows that old buildings on the base are being demolished.

The U.S. has begun production of a new nuclear weapon. Supporters of the weapon say it's needed to counter Russia, but critics worry it's taking America back to a time when nuclear weapons were more likely to be used. NPR's Geoff Brumfiel has more.

The U.S. Department of Energy has started making a new, low-yield nuclear weapon designed to counter Russia.

The National Nuclear Security Administration says production of the weapon, known as the W76-2, has begun at its Pantex Plant in the Texas Panhandle. The fact that the weapon was under production was first shared in an e-mail to the Exchange Monitor, an industry trade magazine, and independently confirmed by NPR.

Earlier this week, Iran attempted to launch a rocket carrying a satellite into space. The Trump administration says their goal is really to develop long-range weapons. NPR's Geoff Brumfiel looks into what Iran is up to.

President Trump unveiled a sweeping plan Thursday to defend the U.S. and its allies from missile attack.

The plan is the first update to the nation's missile defense strategy in nearly a decade, but in many ways it is reminiscent of President Ronald Reagan's Strategic Defense Initiative, a pie-in-the-sky program that was later dubbed "Star Wars."

About once a day, little satellites zip over northern Iran and snap a few pictures of the Imam Khomeini Space Center. The satellites, operated by a company in San Francisco called Planet, haven't recorded much — until recently.

Big, important scientific breakthroughs are built of small, incremental experiments. And the partial government shutdown is already interfering with some of that research.

Scientists often depend on the government for grant funding, expertise and — in some cases — even regulatory approval. With the shutdown, some researchers are missing those key elements of scientific collaboration. Here's how some scientists say the shutdown is affecting their work.

Carbon dioxide emissions in the U.S. are on the rise again after several years of decline, and a booming economy is the cause.

That's according to a report out today from the Rhodium Group, an independent research firm that tracks CO2 emissions in the U.S.

Shoot it down. Jam it. Use a missile or maybe a net.

There's no shortage of ideas about how to stop a drone, but as the past few days at London's Gatwick Airport show, the reality is far more difficult.

From Wednesday night to Friday morning, flights in and out of Gatwick were halted after a small drone, or perhaps multiple drones, were spotted over the airfield. Hundreds of flights were canceled and thousands of passengers saw their holiday travel plans grounded.

For years, the world has imposed strict sanctions on North Korea in an attempt to stop its development of nuclear weapons. Officials from nations across the globe have seized shipments of raw materials, shut down shell companies and interdicted ships smuggling equipment.

But despite these efforts, last year North Korea tested the most powerful weapons known to humanity: a nuclear device far larger than any it had tested before, and an intercontinental ballistic missile that put much of the world, including the U.S., within range.

North Korea appears to be expanding a missile base in a remote, mountainous part of the country, according to new commercial satellite imagery studied by independent researchers.

After meeting with North Korea's leader Kim Jong Un in Singapore this past June, President Trump was effusive.

"Our conversation was open, honest, direct and very, very productive," he said. "We produced something that is beautiful."

But after five months of canceled meetings and muted statements of dissatisfaction by both countries, experts say there is no sign of progress toward the Singapore goal of so-called "denuclearization" of the North.

Commercial satellite imagery has revealed the location and layout of a previously undisclosed North Korean missile base, including deep underground tunnels designed to house the weapons.

The Trump administration is imposing major sanctions on Iran, effectively ending America's participation in a nuclear deal it helped forge in 2015.

Effective Nov. 5, Iran will see sweeping sanctions imposed on its banking, shipping and petroleum sectors. The move will "put a vise on Iran's ability to conduct economic activities internationally," says Corey Hinderstein, a vice president at the nonprofit Nuclear Threat Initiative.
