      Climate Change Can Cause Bridges to ‘Fall Apart Like Tinkertoys,’ Experts Say

      by

      Extreme heat and flooding are accelerating the deterioration of bridges, engineers say, posting a quiet but growing threat.On a 95-degree day this summer, New York City’s Third Avenue Bridge, connecting the Bronx and Manhattan, got stuck in the open position for hours. As heat and flooding scorched and scoured the Midwest, a steel railroad bridge connecting Iowa with South Dakota collapsed under surging waters. In Lewiston, Maine, a bridge closed after the pavement buckled from fluctuating temperatures.America’s bridges, a quarter of which were built before 1960, were already in need of repair. But now, extreme heat and increased flooding linked to climate change are accelerating the disintegration of the nation’s bridges, engineers say, essentially causing them to age prematurely.The result is a quiet but growing threat to the safe movement of people and goods around the country, and another example of how climate change is reshaping daily life in ways Americans may not realize.“We have a bridge crisis that is specifically tied to extreme weather events,” said Paul Chinowsky, a professor of civil engineering at the University of Colorado Boulder who researches the effects of climate change on infrastructure. “These are not things that would happen under normal climate circumstances. These are not things that we’ve ever seen at this rate.”Bridges designed and built decades ago with materials not intended to withstand sharp temperature swings are now rapidly swelling and contracting, leaving them weakened.“It’s getting so hot that the pieces that hold the concrete and steel, those bridges can literally fall apart like Tinkertoys,” Dr. Chinowsky said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Is This Massive Attack Concert the Gold Standard for a Green Gig?

      by

      Coldplay and Billie Eilish have tried to drive down carbon emissions while touring, but the British band Massive Attack has tried to take the efforts even further.When the British band Massive Attack was halfway through a West Coast tour in 2019, flying from show to show, the rapper and singer Robert Del Naja had a moment of crisis. Given all the carbon emitted by moving the band and its equipment around, he recalled wondering: Can I justify this anymore?Not long afterward, the band made a decision. It would work with climate scientists to develop a model for touring that made as little climate impact as possible.On Sunday, Massive Attack staged a daylong 35,000-person festival in the band’s home city of Bristol, England, to showcase the carbon-cutting measures it has developed with the Tyndall Center for Climate Change Research, a British organization, and A Greener Future, a nonprofit focused on lowering the music industry’s emissions.The concert on Sunday was powered by batteries charged from wind and solar energy.Sandra Mickiewicz for The New York TimesFans were encouraged to travel to the show by walking, cycling or using public transportation.Sandra Mickiewicz for The New York TimesWhereas other bands, including Coldplay, have staged attention-grabbing stunts to draw awareness to the industry’s climate impacts, they have sometimes ignored the main sources of emissions from gigs, such as audience travel and venues’ power supplies. With its show on Sunday, Massive Attack wanted to show how to tackle all of the polluting parts of a show.In an interview a few days before the event, Del Naja said that previous music industry efforts to cut emissions had not been in line with the United Nations-agreed goal to stop average temperatures rising more than 1.5 degrees Celsius, or 2.7 Fahrenheit.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Climate Change Is Not a Key Talking Point for Harris Campaign

      by

      In the 2020 presidential election, climate activists demanded that Democratic candidates explain, in detail, how they planned to tackle the planet’s greatest environmental threat.But in the weeks since Vice President Kamala Harris ascended the 2024 Democratic ticket, she has mentioned climate change only in passing, and offered no specifics on how she would curb dangerous levels of warming. Climate leaders say they are fine with that.“I am not concerned,” said Jay Inslee, the Democratic governor of Washington, who made climate change the centerpiece of his own 2019 bid for the presidency. Mr. Inslee said he believes it is more important for Ms. Harris to draw a distinction between her and her Republican rival, former President Donald J. Trump, than to drill down on policy nitty-gritty.“I am totally confident that when she is in a position to effect positive change, she will,” Gov. Inslee said.As Ms. Harris prepares to address the nation on Thursday at the Democratic National Convention, she faces the challenge of energizing party loyalists while also reaching out to disaffected Republicans and moderate voters. So far Ms. Harris and her running mate Tim Walz, the governor of Minnesota, have embraced a pragmatic agenda, calling for things like a minimum-wage increase and child-care funding.While President Biden has made climate change a signature issue, signing into law the largest clean energy investments in American history, Ms. Harris has yet to detail for voters her climate or clean-energy positions. Some analysts chalked that up to strategy and said new promises to slash greenhouse gas emissions or rein in fossil fuels could alienate voters particularly in the energy-rich swing state of Pennsylvania.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Deadly Landslides in India Made Worse by Climate Change, Study Finds

      by

      Extreme rainfall made 10 percent heavier by human-caused climate change triggered landslides that killed hundreds, according to a new study.A sudden burst of rainfall on July 30 caused a cascade of landslides that buried hundreds of people in the mountainous Kerala region of southern India.That downpour was 10 percent heavier because of human-caused climate change, according to a study by World Weather Attribution, a group of scientists who quantify how climate change can influence extreme weather. Nearly six inches, or 150 millimeters, of rain fell on soils already highly saturated from two months of monsoon and marked the third highest single-day rain event on record for India.“The devastation in northern Kerala is concerning not only because of the difficult humanitarian situation faced by thousands today, but also because this disaster occurred in a continually warming world,” said Maja Vahlberg, a climate risk consultant at the Red Cross Red Crescent Climate Centre. “The increase in climate-change-driven rainfall found in this study is likely to increase the number of landslides that could be triggered in the future.”In a state that is highly prone to landslides, the Wayanad district is considered the riskiest part. As of Tuesday, at least 231 people had died and 100 remained missing.The Kerala landslides were the second extreme landslide event in July, following one in Ethiopia that killed 257 people. July was the second-worst month on record, after July 2019, with 95 landslide events that caused 1,167 fatalities, according to data maintained by Dave Petley, the vice-chancellor of the University of Hull. Together, they caused roughly one-third of the more than 3,600 deaths resulting from some 429 fatal landslides recorded this year, Dr. Petley said in an email.Already, 2024 is an outlier, Dr. Petley posted to The Landslide Blog on Tuesday. He wrote that he could “only speculate on the likely underlying reasons for this very high incidence of fatal landslides,” but “the most likely cause continues to be the exceptionally high global surface temperatures, and the resultant increase in high intensity rainfall events.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Heat Contributed to 47,000 Deaths in Europe Last Year, but Relief Programs Helped

      by

      A new study shows that behavioral and social changes can reduce heat mortality. But challenges remain as temperatures continue to rise.More than 47,000 Europeans died from heat-related causes during 2023, the world’s hottest year on record, a new report in Nature Medicine has found.But the number could have been much higher.Without adaptations to rising temperatures over the past two decades — including advances in health care, more widespread air-conditioning and improved public information that kept people indoors and hydrated during extreme temperatures — the death toll for Europeans experiencing the same temperatures at the start of the 21st century could have been 80 percent higher, according to the new study. For people over 80 years old, the death toll could have doubled.“We need to consider climate change as a health issue,” said Elisa Gallo, a postdoctoral researcher at the Barcelona Institute for Global Health, a nonprofit research center, and the lead author of the study. “We still have thousands of deaths caused by heat every year, so we still have to work a lot and we have to work faster.”Counting deaths from extreme heat is difficult, in part because death certificates don’t always reflect the role heat played in a person’s death. The study used publicly available death records in 35 countries, representing about 543 million Europeans and provided by Eurostat, the statistics office of the European Union.The researchers used an epidemiological model to analyze the deaths alongside 2023 weekly temperature records to estimate what fraction of deaths could be attributable to heat.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Heat Raises Fears of ‘Demise’ for Great Barrier Reef Within a Generation

      by

      A new study found that temperatures in the Coral Sea have reached their highest levels in at least four centuries.This generation will probably see the demise of the Great Barrier Reef unless humanity acts with far more urgency to rein in climate change, according to scientists in Australia who released new research on heat in the surrounding ocean.The Great Barrier Reef is the largest coral reef system in the world and is often called the largest living structure on Earth. The study, published on Wednesday in the journal Nature, found that recent extreme temperatures in the Coral Sea are at their highest in at least 400 years, as far back as their analysis could reach.It included modeling that showed what has been driving those extremes: Greenhouse gas emissions caused by humans burning fossil fuels and destroying natural places that store carbon, like forests.“The heat extremes are occurring too often for those corals to effectively adapt and evolve,” said Ben Henley, a paleoclimatologist at the University of Melbourne and an author of the new study. “If we don’t divert from our current course, our generation will likely witness the demise of one of Earth’s great natural wonders, the Great Barrier Reef.”The study’s scientific prose put it this way: “The existential threat to the Great Barrier Reef ecosystem from anthropogenic climate change is now realized.”Tanya Plibersek, Australia’s environment minister, said in a statement that the government understood its responsibility to act on climate change and safeguard the reef. She pointed to a recent law that calls for a 43 percent reduction of emissions by 2030 and to $1.2 billion in measures to protect the reef.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
