    A Heat Wave Hits New York Earlier Than Usual for a Second Year in a Row

    by

    Climate change is increasingly making weather extremes more common.Scorching, record-breaking temperatures on Tuesday kept many people indoors throughout the metropolitan region, strained the electrical grid and stoked concerns among those who are the most vulnerable to the heat, including older New Yorkers and the very young.It was 99 degrees in Central Park this afternoon, the hottest June 24 temperature since records started there in 1869. Kennedy Airport recorded the hottest June day since the site was built in 1948, at 102 degrees.It is the second year in a row that a heat wave has hit the New York City region earlier than usual, as global warming is projected to worsen heat waves and make them more frequent, climate experts say.“Our warming climate underlies everything,” said David Robinson, the New Jersey state climatologist and a geography professor at Rutgers University. “It’s not about the highest temperature; it’s about how long it stays hot and the area of coverage of that heat. It’s 100 up in New England today and down here as well.”Of the 69 weather stations in New Jersey, Mr. Robinson said, over 30 hit 100 degrees. He added that the 10 hottest summers on record for the state had all occurred since 2005.As climate change wreaks havoc with the traditional calendar, the familiar rhythms of the seasons have begun to shift. New York City pools, for example, are not scheduled to open for the summer until Friday.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Dangerous Heat Wave Expands Over Central and Eastern United States

      by

      A multiday heat wave is bringing high temperatures and health risks from the Midwest to the Northeast, prompting warnings and emergency measures.A relentless and intensifying heat wave is expanding across the central and eastern United States this week, bringing well-above-average heat to millions of people from the Midwest to the East Coast and prompting health advisories across several states.After pushing temperatures to around 100 degrees in parts of Iowa, Minnesota, Nebraska and South Dakota on Saturday, the heat is expected to continue over the Midwest and shift eastward on Sunday.By midweek, the heat is expected to affect major urban areas, including New York City, Philadelphia and Washington.“This is the deadliest weather threat we face in New York City — treat it that way,” the city’s Emergency Management said on social media on Saturday. “Don’t wait until you feel sick. Heat builds. It compounds. It kills quietly.”New York City officials noted that more than 500 residents die prematurely each year from heat-related causes, and they expect oppressive temperatures to persist through at least Tuesday.In Philadelphia, the Department of Public Health issued a heat health emergency, beginning at noon on Sunday and continuing through Wednesday evening.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Midwest Cities Bake as Heat Wave Blankets the Central U.S.

      by

      St. Louis, Omaha and Des Moines were among the cities that saw heat indexes rise toward triple digits, with similar temperatures expected on the East Coast by Monday.Dick Kraklow rolled into Minneapolis earlier this week with three generations of his family and several vintage vehicles in tow, excited for an annual gathering of the Minnesota Street Rod Association that celebrates classic cars.But instead of setting up on Saturday morning to display their collection, Mr. Kraklow, 42, and his family were loading up to drive back to Wisconsin. Several members of the group are in their late 70s, and the heat radiating off the asphalt at the state fairgrounds in St. Paul on Friday caused the family to change plans.“We love the show,” Mr. Kraklow, a welder from Muskego, Wis., said as his uncle angled a yellow 1957 Ford Thunderbird onto a trailer. But ultimately, he said, “It’s too hot.” Millions of Americans on Saturday faced sweltering conditions as a dangerous heat wave brought rising temperatures to the Midwest and Central Plains. By early afternoon, the National Weather Service reported that the heat index — a measure of how hot it feels that accounts for both heat and humidity — had hit 93 degrees in Minneapolis, 98 in Des Moines, 99 in Sioux Falls, S.D., and 105 in St. Louis. In Omaha, forecasters said that it would feel like it was 100 to 110 degrees this weekend — in the shade.The most extreme heat was expected to move east and south over the next several days. New York City, Washington and Philadelphia could all break 100 degrees on the heat index by the end of the weekend. Several cities could see heat records broken. Over the entire country, more than 64 million people were under an extreme heat warning.Climate scientists have found that climate change has made heat waves more common, more intense and longer lasting worldwide, though attributing a specific heat wave to climate change is tricky.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Sweating to Shivering: Study Finds Rapid Swings in Temperature Have Increased

      by

      Flips between warm temperatures to cold and vice versa have become quicker, more frequent and more intense in recent decades, a new study shows.Wildfire smoke tinged the sky orange in Fort Collins, Colo., in the Rocky Mountains region on Sept. 7, 2020, during a heat wave, before temperatures dropped significantly overnight and a snowstorm hit the area.A September heat wave switching into a snowstorm over one day in the Rocky Mountains. Winter snowfall suddenly melting and saturating fields of dormant crops, before refreezing and encasing them in damaging ice. Early spring warmth prompting plants to blossom followed by a cold snap that freezes and drops their petals.Rapid temperature change events like these have increased in frequency and intensity over recent decades, a new study found.The transition periods for these abrupt temperature shifts have also shortened, according to the study, published Tuesday in the journal Nature Communications.Because the quick changes in temperature give communities and ecosystems little chance to respond, they may pose greater challenges than heat waves or cold snaps alone, said Wei Zhang, an assistant professor of climate science at Utah State University and one of the lead authors of the study.“The impact could really be cascading on a different level,” he said.The researchers warned these temperature flips could have damaging effects on people and natural environments, including destruction of crops, harm to ecosystems and strains on power infrastructure. And low-income countries, where there is less access to weather forecasting and infrastructure is less resilient, are more vulnerable.The researchers examined temperature data from 1961 to 2003 to identify global patterns in sudden weather shifts, where temperatures in an area either jumped from cold temperatures to warm or plunged from warm to cold within five days. They found that instances of these flips increased in more than 60 percent of regions they surveyed.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      The Vicious Cycle of Extreme Heat Leading to More Fossil Fuel Use

      by

      A new report illustrates a concerning dynamic: Record heat last year pushed countries to use more planet-warming fossil fuels to cool things down.Last year was the hottest on record, and global average temperatures passed the benchmark of 1.5 degrees Celsius above preindustrial times for the first time. Simultaneously, the growth rate of the world’s energy demand rose sharply, nearly doubling over the previous 10-year average.As it turns out, the record heat and rapidly rising energy demand were closely connected, according to findings from a new report from the International Energy Agency.That’s because hotter weather led to increased use of cooling technologies like air-conditioning. Electricity-hungry appliances put a strain on the grid, and many utilities met the added demand by burning coal and natural gas.All of this had the makings of a troubling feedback loop: A hotter world required more energy to cool down homes and offices, and what was readily available was fossil-fuel energy, which led to more planet-warming emissions. This dynamic is exactly what many countries are hoping to halt through the development of renewable energy and the construction of nuclear power plants.Put another way, the I.E.A. estimated that if 2024’s extreme weather hadn’t happened — that is, if weather was exactly the same in 2024 as in 2023 — the global increase in carbon emissions for the year would have been cut in half.It’s not all bad news: Increasingly, the global economy is growing faster than carbon emissions. “If we want to find the silver lining, we see that there is a continuous decoupling of economic growth from emissions growth,” said Fatih Birol, the executive director of the agency.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 Made South Sudan Heat Wave More Likely, Study Finds

      by

      Years of war and food insecurity in the region made the extreme heat especially dangerous.After a blistering February heat wave in South Sudan’s capital city caused dozens of students to collapse from heat stroke, officials closed schools for two weeks. It was the second time in less than a year that the country’s schools closed to protect young people from the deadly effects of extreme heat.Climate change, largely caused by the burning of fossil fuels in rich nations, made at least one week of that heat wave 10 times as likely, and 2 degrees Celsius hotter, according to a new study by World Weather Attribution. Temperatures in some parts of the region soared above 42 degrees Celsius, or 107 degrees Fahrenheit, in the last week of February.The analysis used weather data, observations and climate models to get the results, which have not been peer reviewed but are based on standardized methods.South Sudan, in the tropical band of East Africa, was torn apart by a civil war that led to independence from Sudan in 2011. It’s also one of the countries least responsible for the greenhouse gas emissions that are heating up the globe. “The continent has contributed a tiny fraction of global emissions, but is bearing the brunt of climate change,” said Joyce Kimutai, a researcher at the Center for Environmental Policy at Imperial College London.Heat waves are one of the deadliest extreme weather events and have become more frequent and more severe on a warming planet. But analysis methods connecting heat to mortality vary between and within countries, and death tolls can be underreported and are often unknown for months after an event.Prolonged heat is particularly dangerous for children, older adults and pregnant women. For the last three weeks, extreme heat has settled over a large region of continental Eastern Africa, including parts of Kenya and Uganda. Residents have been told to stay indoors and drink water, a difficult directive for countries where many people work outdoors, electricity is sporadic, access to clean water is difficult and modest housing means there are few cooling systems.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Trading Hope for Reality Helps Me Parent Through the Climate Crisis

      by

      When I gave birth to my first child, in 2019, it seemed like everything that could possibly go wrong went wrong. He came out white and limp, his head dangling off to the side. People swarmed into the hospital room, trying to suction his lungs so he could breathe. Hours later, my husband and I stood in the NICU, looking down at this newborn baby, hooked up to wires and tubes.We had spent months talking about how to protect him from various harmful influences, and here we were, an hour out of the gate, dealing with a situation we hadn’t even considered. Had his brain been deprived of oxygen for too long? Would there be lifelong damage?That night in the hospital, I learned the first lesson of parenting: You are not in control of what is going to happen, nor can you predict it. This applies to your child’s personality, many of his choices and to some extent his health. It also applies to the growing threat of climate change.The climate crisis is bad and getting worse. Here in Oregon, we’ve endured several severe heat waves and wildfires in recent years. As the impacts compound, it’s clear a lot of people around the world — many of them children — are going to suffer and die.Globally, one in three children is exposed to deadly heat waves, and even more to unclean water. A study estimated wildfire smoke to be 10 times as harmful to children’s developing lungs as typical pollution. Researchers also concluded that nearly every child in the world is at risk from at least one climate-intensified hazard: extreme heat, severe storms and floods, wildfires, food insecurity and insect-borne diseases.If you are someone like me who has children and lies awake terrified for their future, you should not let hopelessness about climate change paralyze you. In fact, I would argue that right now the bravest thing to do — even braver than hoping — is to stop hoping.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Wildfire Erupts in Orange County, Forcing Evacuations

      by

      A small brush fire in Southern California quickly grew into a nearly 2,000-acre blaze, threatening nearby suburban neighborhoods.A brush fire that erupted on Monday afternoon in the hills of Orange County in Southern California exploded to nearly 2,000 acres within a few hours, prompting evacuation orders for nearby communities as the blaze burned uncontrolled.Known as the Airport fire, it began just before 1:30 p.m. about 15 miles east of Irvine, Calif., near an airport for remote-controlled model airplanes. Officials have ordered evacuations in parts of Trabuco Canyon, a community in the foothills of the Santa Ana Mountains, and have recommended evacuations for surrounding neighborhoods as well.The fire broke out during a prolonged heat wave that has pushed temperatures in many parts of Southern California into the triple digits in recent days. A fire in the San Bernardino Mountains that began on Thursday, about 55 miles northeast of Trabuco Canyon, has swelled to threaten more than 33,000 structures and is only 5 percent contained.In Trabuco Canyon, temperatures reached about 98 degrees on Monday, above normal for early September, said Samantha Zuber, a meteorologist with the National Weather Service in San Diego. Wind speeds were about 15 miles per hour, she said.The winds are expected to slow into the evening, but overnight temperatures will remain unusually high, unlikely to drop below 70 degrees, she said. Similar conditions have been fueling wildfires in the state all summer. “Unfortunately, temperatures won’t cool that much,” Ms. Zuber said.She said that temperatures in the fire zone would begin to drop on Tuesday — a high of 95 is expected — before a significant cool down, which is forecast to start on Wednesday and continue for the rest of the week.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
