As part of this year’s Climate Forward conference, the team wanted to find a new way for attendees to understand how our planet is changing. Producer Evan Roberts talked to scientists and researchers who are capturing natural soundscapes before they change forever. The Climate Forward team compiled the work of three field recordists to create an audio installation, called the Sounds of Climate Change. This soundscape offers a sonic tour of the Amazon rainforest. Izabela Dluzyk, a field recordist originally from Poland, grew up memorizing bird calls and listening closely to sparrows. Inspired by a fascination with parrots, she crowd-funded her way to the Tambopata National Reserve in Peru to record the dusk and dawn symphonies of the rainforest. Blind since birth, Ms. Dluzyk was accompanied into acoustically lush areas of the Amazon by her brother and her Amazonian guide. She captured a thunderous ritual of macaws gathering at eroding clay banks along the Tambopata River, eating the sodium-rich soil that is essential to their health and to raising their chicks. But years of severe droughts threaten to disrupt that delicate balance and turn the sound-rich canopy into grassland. “Rainforests are so fragile,” Ms. Dluzyk said. “ We need to become fascinated with what we can hear.” To learn more, sign up for the Climate Forward newsletter.

As part of this year’s Climate Forward conference, the team wanted to find a new way for attendees to understand how our planet is changing. Producer Evan Roberts talked to scientists and researchers who are capturing natural soundscapes before they change forever. The Climate Forward team compiled the work of three researchers to create an audio installation, called the Sounds of Climate Change. This soundscape offers a sonic tour of a melting glacier. Ludwig Berger, a German sound artist from Alsace in France, first recorded the sounds of the Morteratsch Glacier in Switzerland more than a decade ago. What he heard astonished him: deep resonances of ancient air bubbles being released from crevices and making sounds like wailing synthesizers. As Mr. Berger put it, he records “last sounds.” Each time he returns to record, he has to climb farther up the mountain to reach the ice, as the glacier has retreated. The locations of many of the sounds you’ll hear in his soundscape are now gone, he said. “There’s no ice left there, there’s just a bare rock,” he said.

As part of this year’s Climate Forward conference, the team wanted to find a new way for attendees to understand how our planet is changing. Producer Evan Roberts talked to scientists and researchers who are capturing natural soundscapes before they change forever. The Climate Forward team compiled the work of three researchers to create an audio installation, called the Sounds of Climate Change. This soundscape offers a sonic tour of the underwater Arctic. Bernie Krause, a prominent audio ecologist, coined the term “biophony” to describe earthly sounds from nonhuman organisms, like the calls, songs and buzzes produced by animals and insects. Paired with nonbiological sounds of the Earth, or the “geophony,” these layers of sound make up the ambient symphony of our planet. And as our planet warms, this natural soundscape is shifting in surprising ways. For those who have spent their careers listening closely, these changes are not abstract. “When I started going up to the Arctic, I thought I would be spending my career listening to bowhead whales,” said Kate Stafford, a bioacoustician at Oregon State University, who recorded this soundscape. “But what I’ve ended up doing is listening to climate change.” Dr. Stafford records what she calls the “underwater jungle.” By lowering hydrophones, or waterproof microphones, into the frigid ocean, she captures bowheads moaning, belugas whistling and even the deafening sound of air guns being used in oil exploration. She has heard the shrinking sea ice disrupt animal migration patterns and introduce new predators. As the planet warms, the waters of the ice-covered Arctic is becoming louder and stormier.

For the first time in a generation, demand for electricity in the U.S. is growing, fueled by A.I.’s insatiable thirst for power. And yet, President Trump has taken severe steps to slow the deployment of solar and wind. At the Climate Forward live event, Scott L. Strazik, the C.E.O. of GE Vernova, spoke about what his company is doing to meet the demand, what A.I. means for the American grid and how Trump’s war on wind power has affected his company.

President Trump has rapidly pulled the U.S. out of the fight against climate change, fired scientists, rolled back regulations and gutted the nation’s largest-ever law to address climate change. That has left climate activists reeling. Abigail Dillen, president of Earthjustice; Manish Bapna, president of the Natural Resources Defense Council; and Bill McKibben, an author and activist, talk with Cara Buckley about what has worked — and failed — in the climate movement.

At the Climate Forward live event, Melanie Nakagawa and Kate Brandt, the chief sustainability officers at Microsoft and Google, discussed how the boom in artificial intelligence was affecting their companies’ goals to achieve net-zero emissions or better by 2030.The industry is building out data centers at a breakneck pace, which has led to a rise in technology companies’ emissions in recent years. What will it take to power the A.I. revolution without further fueling the climate crisis? Nakagawa and Brandt discuss their companies’ investments in nuclear energy, carbon capture and other clean energy technologies.

As climate change accelerates, its consequences are reshaping global security. At the Climate Forward live event, Jake Sullivan, President Joe Biden’s national security adviser, said the Trump administration’s climate policies could pose a national security threat to the United States. This risk is already real to many in the military, he said. “Any man or woman with stars on their shoulders or general officers,” Sullivan said, “and they will tell you the climate crisis is real and has an operational impact on them.”In a conversation with Helene Cooper, Sullivan discussed about how climate change was shaping the U.S. competition with China and how a rapidly warming planet was creating new threats, from growing food insecurity in developing nations to transforming the battlefields of the future.

Gov. Gavin Newsom of California, a Democrat, runs a state that is in the middle of several high-stakes court battles against the Trump administration, including over its rollback of automobile emission standards and other moves. But California has also experienced a wave of climate-driven natural disasters and rising home insurance prices. In a conversation with David Gelles, Newsom discussed the Los Angeles fires, the state’s rapidly changing climate and why he calls President Trump’s recent speech to the United Nation’s General Assembly “an abomination.”

As energy secretary under President Trump, Chris Wright, a former fracking executive, has helped to shape an energy agenda defined by deregulation and fossil fuel expansion. In a conversation with David Gelles, Mr. Wright explained why he would “absolutely” like to see countries follow the lead of the United States under the Trump administration and withdraw from the Paris Agreement on climate change. Wright also forcefully defended the Trump administration’s crackdown on wind and solar power, claiming that there was a “fever pitch” of opposition around the country to the technologies.

Few people in the world are more responsible for climate change being part of the public discourse than former Vice President Al Gore, a recipient of the Nobel Peace Prize for his environmental activism. But, as President Trump has swiftly pulled the U.S. away from the global fight against climate change, the future of the movement is uncertain. In a frank conversation with David Gelles, Gore talks about the future of the battle to save our rapidly warming planet.
