Rebecca Hersher

Rebecca Hersher (she/her) is a reporter on NPR's Science Desk, where she reports on outbreaks, natural disasters, and environmental and health research. Since coming to NPR in 2011, she has covered the Ebola outbreak in West Africa, embedded with the Afghan army after the American combat mission ended, and reported on floods and hurricanes in the U.S. She's also reported on research about puppies. Before her work on the Science Desk, she was a producer for NPR's Weekend All Things Considered in Los Angeles.

Hersher was part of the NPR team that won a Peabody award for coverage of the Ebola epidemic in West Africa, and produced a story from Liberia that won an Edward R. Murrow award for use of sound. She was a finalist for the 2017 Daniel Schorr prize; a 2017 Pulitzer Center on Crisis Reporting fellow, reporting on sanitation in Haiti; and a 2015 NPR Above the Fray fellow, investigating the causes of the suicide epidemic in Greenland.

Prior to working at NPR, Hersher reported on biomedical research and pharmaceutical news for Nature Medicine.

The National Oceanic and Atmospheric Administration upgraded the computer model that forecasters use to predict the weather one to two weeks in the future, called the Global Forecast System. The new model is better at predicting where hurricanes will form and how intense they will be as well as where and when snowstorms and rainstorms will occur, and how much precipitation will fall.

"This is going to have a fundamental impact on the forecasts that are provided day to day," says Louis Uccellini, director of the National Weather Service.

Humans have changed the Earth in such profound ways that scientists say we have entered a new geological period: the Anthropocene Epoch.

But when did the new epoch officially begin? And how, exactly, should it be defined?

Those are the questions that geologists are pursuing with increasing urgency at sites around the world. Teams are studying 11 locations on five continents, looking for a place where rock, mud or ice perfectly capture the global impact of humans.

Pastor Aaron Trigg was at home when the water arrived in Rainelle. It had been raining hard all day, filling the creeks and rivers that run through southern West Virginia. In the past, such intense downpours would last only a few hours, but this storm brought wave after wave of torrential rain.

"You could hear the water up in the mountains just crashing trees," Trigg remembers.

Rainelle is a small town in a steep valley. When the creek near downtown jumped its banks on the evening of June 23, 2016, the water immediately flooded into every home on Trigg's block.

A suspected oil tanker leak off the coast of Israel last week has led to Israel's biggest maritime ecological disaster in many years, with authorities closing the country's beaches and beginning a massive cleanup effort.

Millions of Texas residents suffered last week when a winter storm caused a statewide electrical grid failure. But those who had power, even intermittently, are also paying a price — literally.

Many residents face enormous bills for the electricity they used during the storm.

Residents with variable-rate power plans are being hit the hardest. Such plans charge different prices for electricity depending on how much demand there is. The more demand, the higher the price.

Federal scientists have confirmed that 2020 basically tied with 2016 for the hottest year recorded since 1880. The Earth is about 2 degrees Fahrenheit warmer today than it was in the mid-20th century. Scientists warn that humans must keep global temperatures from rising more than about 3 degrees Fahrenheit in order to avoid the most catastrophic effects of climate change.

Devon Hall has lived most of his nearly seven decades in Duplin County, N.C. The land is flat and green there in the southeastern part of the state, about an hour's drive from the coast. It's lovely unless you live downwind of one of the county's many industrial hog farms.

"It can get really bad," says Hall, the co-founder of the Rural Empowerment Association for Community Help in Duplin County.

The Supreme Court heard arguments on Tuesday in a case brought by the city of Baltimore against more than a dozen major oil and gas companies including BP, ExxonMobil and Shell. The city government argued that the fossil fuel giants must pay for the costs of climate change because they knew that their products cause potentially catastrophic global warming.

The Environmental Protection Agency adopted a new rule restricting the types of scientific studies its own regulators can use to rein in pollution, in the Trump administration's latest effort to undercut the use of science in establishing public health standards.
