Lauren Sommer

Lauren Sommer covers climate change for NPR's Science Desk, from the scientists on the front lines of documenting the warming climate to the way those changes are reshaping communities and ecosystems around the world.

Prior to joining NPR, Sommer spent more than a decade covering climate and environment for KQED Public Radio in San Francisco. During her time there, she delved into the impacts of California's historic drought during dry years and reported on destructive floods during wet years, and covered how communities responded to record-breaking wildfires.

Sommer has also examined California's ambitious effort to cut carbon emissions across its economy and investigated the legacy of its oil industry. On the lighter side, she ran from charging elephant seals and searched for frogs in Sierra Nevada lakes.

She was also host of KQED's macrophotography nature series Deep Look, which searched for universal truths in tiny organisms like black-widow spiders and parasites. Sommer has received a national Edward R. Murrow for use of sound, as well as awards from the Society of Professional Journalists and the Society of Environmental Journalists.

Based at NPR's San Francisco bureau, Sommer grew up in the West, minus a stint on the East Coast to attend Cornell University.

Off the coast of England, there's a tiny, wind-swept island with the remains of a lifeboat rescue station from the mid-1800s. The workers who once ran the station on Hilbre Island did something that, unbeknownst to them, has become crucial for understanding the future of a hotter climate: They recorded the tides.

In a flurry of first-week executive orders, President Biden sent a definitive message that his administration would move faster on climate change than any before. Now, the question is whether it will be fast enough.

And for more on what today's executive actions mean, we are joined by Lauren Sommer of NPR's climate team, who's been listening in to that conversation.

Hi, Lauren.

LAUREN SOMMER, BYLINE: Hi, Ari.

President Biden is moving quickly on climate change on his first day in office, saying he plans to sign a sweeping executive order to undo many of the Trump administration's environmental rollbacks.

As commuters stayed home in 2020 and airplanes remained on the ground, the nationwide slowdown led to a sizable drop in heat-trapping emissions. U.S. greenhouse gas emissions fell by 10 percent, the largest annual drop since World War II, according to a report by the Rhodium Group.

Still, the climate diet isn't likely to stick. The reductions were largely due to temporary changes during lockdown orders. By the end of the year, Americans were already back to driving and flying more.

In addition to being the year of COVID, 2020 was also a year of extreme wildfires and hurricanes, in part because global temperatures were among the hottest ever recorded. Here's NPR's Lauren Sommer.

With just a few weeks left, 2020 is in a dead-heat tie for the hottest year on record. But whether it claims the top spot misses the point, climate scientists say. There is no shortage of disquieting statistics about what is happening to the Earth.

The pandemic is having some unintended consequences on the environment. There's less air pollution. And now scientists are finding that water quality is improving, too. NPR's Lauren Sommer reports.

After record-breaking wildfires this year, thousands of people across the West are still clearing piles of charred debris where their homes once stood in the hope of rebuilding their lives.

With climate change fueling bigger, more destructive wildfires, rebuilding offers an opportunity to create more fire-resistant communities by using building materials that can help homes survive the next blaze.

Firefighters in Colorado are battling explosive wildfires at a time of year when things are normally quieter. As NPR's Lauren Sommer reports, climate change is extending the fire season across the West.

Jennifer Montano watches her two kids' faces as they quietly clamber out of the car in their driveway in Vacaville, Calif. It's been a week since the children were last home, but where their house once stood, there's ash and rubble now.

In August, the Montanos' house was destroyed by the LNU Lightning Complex Fire, one of more than 10,000 structures lost in record-breaking blazes across the West this year.

Bigger and more destructive wildfires are on the rise in the U.S., driven in great part by a changing climate. More than 40 million Americans live in high-risk zones because towns have increasingly expanded into fire-prone landscapes. Even if a home seems far from forests or grasslands, wildfires can easily spread into towns and suburbs, as thousands of homeowners in the West have experienced recently in deadly fires.

Each family had their reasons for ending up in harm's way.

For the Harts, it was the chance to have a large backyard in a quiet part of Ashland, Ore. The porch of the Baltimore house was perfect for Scott Harris' barbecue equipment. Kevin Boudreaux had grown up on the bayou and wanted to settle near his childhood home in Cameron, La.

California will phase out the sale of all gasoline-powered vehicles by 2035 in a bid to lead the U.S. in reducing greenhouse gas emissions by encouraging the state's drivers to switch to electric cars.

Gov. Gavin Newsom signed an executive order Wednesday that amounts to the most aggressive clean-car policy in the United States. Although it bans the sale of new gas cars and trucks after the 15-year deadline, it will still allow such vehicles to be owned and sold on the used-car market.

It's become a near-annual occurrence. A massive wildfire forces thousands of people to flee their homes. Exhausted firefighters warn of its speed and intensity. Smoke smothers cities and states hundreds of miles away.

The upshot of climate change is that everyone alive is destined to experience unprecedented disasters. The most powerful hurricanes, the most intense wildfires, the most prolonged heat waves and the most frequent outbreaks of new diseases are all in our future. Records will be broken, again and again.

But the predicted destruction is still shocking when it unfolds at the same time.

Millions of people rely on real estate websites when they're hoping to buy or rent a home. Major sites such as Zillow, Redfin, Trulia and Realtor.com feature kitchens, bathrooms, mortgage estimates and even school ratings. But those sites don't show buyers whether the house is likely to flood while they're living there.

On a cool February morning, around 60 people gathered in the Sierra Nevada foothills to take part in a ceremony that, for many decades, was banned.

At 3 a.m. on Friday morning, biologist Kelly Sorenson was awake, nervously watching the live webcam feed of a California condor nest on the Big Sur coast. He could see a 5-month-old chick, still unable to fly, as the flames of the Dolan Fire came into view.

"It was just terrifying," Sorenson said. "Having the live-streaming webcams was both a blessing and a nightmare because we had to watch the fire as it burned through the canyon."

Scorching heat across the Western United States has left California scrambling to avoid rolling blackouts, as air conditioners send electricity use soaring.

They're wiggly and slimy and live inside the flesh of other animals. Now, scientists are making a new case for why they should be saved.

Parasites play crucial roles in ecosystems around the world, making up around 40% of animal species. As wildlife faces the growing threats of climate change and habitat loss, scientists warn that parasites are equally vulnerable.

That's why a team of scientists has released a "global parasite conservation plan."

President Trump is attacking Democrats on a new front: suburbia.

"They want to eliminate single-family zoning, bringing who knows into your suburbs," Trump said on a July campaign call.
