Climate and environment updates: Dangerous hurricanes made worse by climate change

(NEW YORK) — The climate crisis is not a distant threat; it’s happening right now and affecting what matters most to us. Hurricanes intensified by a warming planet and drought-fueled wildfires are destroying our communities. Rising seas and flooding are swallowing our homes. And record-breaking heatwaves are reshaping our way of life.

The good news is we know how to turn the tide and avoid the worst possible outcomes. However, understanding what needs to be done can be confusing due to a constant stream of climate updates, scientific findings, and critical decisions that are shaping our future.

That’s why the ABC News Climate and Weather Unit is cutting through the noise by curating what you need to know to keep the people and places you care about safe. We are dedicated to providing clarity amid the chaos, giving you the facts and insights necessary to navigate the climate realities of today — and tomorrow.

Dangerous hurricanes are being made even worse because of climate change, study finds

Hurricanes are getting stronger, and humans are primarily to blame. A new study from Climate Central adds to a growing body of evidence that human-amplified climate change is indeed leading to more intense storms.

The study, published in the journal Environmental Research: Climate, found that 84% of Atlantic hurricanes between 2019 and 2023 were, on average, 18 mph stronger because of climate change. That additional wind speed resulted in 30 hurricanes reaching an entire category higher in strength (Category 3 to Category 4 or Category 4 to Category 5, for example) compared to a world without human-amplified climate change.

The researchers say sea surface temperatures are being made hotter by global warming, fueling these rapidly intensifying cyclones. The authors cite Hurricane Milton as an example. They found that Milton intensified by 120 mph in under 36 hours. At the time, ocean temperatures were at record levels or near record levels, which Climate Central’s Climate Shift Index: Ocean determined were made 400 to 800 times more likely by climate change.

Over the past half-century, the ocean has stored more than 90% of the excess energy trapped in Earth’s system by greenhouse gases and other factors, according to the National Oceanic and Atmospheric Administration.

“Every hurricane in 2024 was stronger than it would have been 100 years ago,” Dr. Daniel Gilford, climate scientist at Climate Central and lead author of the study and report, said in a statement. “Through record-breaking ocean warming, human carbon pollution is worsening hurricane catastrophes in our communities.”

The researchers identified three storms between 2019 and 2023 that became Category 5 hurricanes, the highest level on the scale, because of our changing climate.

When the scientists applied the same study methodology to storms in 2024, they determined it was unlikely Beryl and Milton would have reached Category 5 status without the impact of climate change. And they found that every Atlantic hurricane in 2024 saw an increased maximum wind speed, ranging from 9 to 28 mph, because human-amplified climate change resulted in elevated ocean temperatures.

Since 1980, tropical cyclones, a generic term for hurricanes and tropical storms, have cost communities $1.4 trillion in damages and claimed more than 7,200 lives, according to The National Center for Environmental Information.

Biden pledges $325 million in clean tech funding for developing nations

On Tuesday, the Biden administration announced $325 million in funding to the Clean Technology Fund (CTF) for global clean energy projects. The funding comes as climate leadership conferences continue worldwide, with COP29 underway in Azerbaijan and the G20 summit in Brazil.

Projects range from implementing renewable energy sources, like solar and wind, to more efficient energy use in transportation.

The Clean Technology Fund provides money for permanent climate projects for middle-income and developing countries, allowing them to jump the financial hurdle and implement much-needed new green tech and energy.

Nine countries currently give money to the Fund through grants and loans. Operated by the World Bank, the program distributes money to eligible countries through global development banks.

This financial commitment is another example of the Biden administration trying to lock in climate funding and programs before President-elect Donald Trump takes office.

Since 2022, the U.S. has contributed $1.56 billion in concessional loans to the fund, and in October of this year, they contributed another $20 million in grants. Since it was established in 2008, the Fund has contributed $7.28 billion in loans and grants globally.

A report released last week highlighted that advancing climate progress in middle-income countries is crucial for setting the world on a path to achieving carbon neutrality by 2050. These countries are not only the most vulnerable to the impacts of climate change, but they also host the majority of the world’s nature and biodiversity.

Countries pledge to reduce potent greenhouse gas that comes from food waste at COP29

As the world’s nations try to decide on a plan of action for limiting the impacts of climate change, the head of the United Nations Environment Programme says reducing methane emissions could be the “emergency brake” the world needs.

Methane is a potent greenhouse gas responsible for about 30% of the rise in global temperatures since industrialization, according to the International Energy Agency.

“Reducing methane emissions this decade is our emergency brake in the climate remit,” Martina Otto, head of the Secretariat, Climate and Clean Air Coalition at the UNEP, said at a press conference with the COP29 presidency.

“To cut the emergency we need to harness the fact that methane has a much higher global warming potential and is shorter lived in the atmosphere, which means we can curb near-term warming.”

Tuesday is food, water and agriculture day at COP29 – an occasion marked this year by a new agreement to cut methane emissions from food waste.

Over 30 countries have already committed to the Declaration on Reducing Methane from Organic Waste, which targets methane emissions from organic waste like food. The move complements additional global efforts to tackle methane emissions, including the Global Methane Pledge, which aims to reduce methane emissions by 30% by 2030.

“Urgent work is needed to help the agricultural sectors adapt to a warming planet,” COP29 lead negotiator Yalchin Rafiyev said.

Rafiyev explained that the Baku Harmoniya Climate Initiative for Farmers — an effort launched by the UN Food and Agriculture Organization (FAO) and the COP29 presidency — will give farmers tools for building climate resilience and secure funding.

“We are also committed to taking every opportunity for mitigation, particularly on methane,” Rafiyev said, noting previous COP’s progress on methane emissions. “We must address all the major sources of methane emissions, including fossil fuels, agriculture and organic waste.”

“Transforming agriculture and food systems is going to be critical if we are to achieve the Paris Agreement, whether it’s on the side of adaptation and building resilience, or indeed on the side of mitigation,” Kaveh Zahedi, director of the Office of Climate Change, Biodiversity and Environment at the FAO, said. “And on this food, agriculture and water day, we’re so delighted that the cop 29 presidency has been shining a light on this.”

UN climate lead says millions of lives are at stake and delegates should ‘cut the theatrics’

As COP29, the annual U.N. global climate conference, heads into its second and final week, the United Nations’ top climate representative is reminding delegates of what’s at stake if they fail to act now.

During his opening remarks on Monday, Simon Stiell, the U.N. climate change executive secretary, chastised the delegates, warning them that they are losing sight of the forest because they are “tussling over individual trees” and that “bluffing, brinksmanship and pre-mediated playbooks burn up precious time.”

“So let’s cut the theatrics and get down to real business,” he said.

Later in the day, Stiell urged climate leaders and public officials to unite on adaptation policy and finance.

“This year, we saw how every bit of preparation – every policy, every plan – is the difference between life and death for millions of people around the world,” Stiell said.

Stiell emphasized that we know how to adapt to our changing climate technologically but need the will to act.

“We have the tools, the science, the ability to achieve these outcomes,” he said.

The biggest roadblock, he said, is ensuring countries have enough money to do the work.

“Of course, we cannot ignore the adaptation elephant in the room: there is a stark financial gap we must bridge,” Stiell said.

According to Stiell, the expenses associated with adaptation are rapidly increasing, especially for developing nations. By 2030, these expenses could amount to $340 billion annually and soar to $565 billion annually by 2050.
Without proper funding, he said billions of lives are on the line.

“The IPCC’s Working Group II report told us that almost half the human population live in climate vulnerable hotspots, where people are 15 times more likely to die from climate impacts,” Stiell said.

Stiell encouraged public and private sector funders to rise to the occasion and meet global needs in new ways.

“Think beyond traditional grants and loans,” Stiell said. “Philanthropies, the private sector, and bilateral donors must step up with the urgency that this crisis demands.”

He added, “The funding exists. We need to unlock and unblock it.”

Hundreds of US counties lack sufficient air quality monitoring

Cities, counties and government agencies use air quality monitors to measure the pollutants and particulates that can cause significant health problems. However, according to a new report, hundreds of counties across the United States lack these essential measurement tools.

According to the American Lung Association’s 2024 State of the Air report, more than two-thirds of U.S. counties do not have official ground-based air quality monitoring stations. As a result, dangerous levels of pollution are going undetected and unaddressed.

The association used satellite data to estimate that 300 of the 2,700 U.S. counties with incomplete or no air monitoring data had potentially failing grade levels of fine particulate matter between 2020 and 2022.

Lexi Popovici, lead report author and a senior manager of the American Lung Association, said satellite data could help fill the data gap left by the missing air monitors and help people and officials, particularly in rural areas, take protective measures. She said the technology could also supplement existing ground monitors and ultimately create a more comprehensive air quality monitoring system.

“Using satellite data actually helps fill in those gaps to identify pollution in places that might otherwise go undetected, and this can help millions of Americans understand what air quality they are breathing,” Popovici said.

Earlier this year, the Environmental Protection Agency introduced a more stringent national annual average standard based on the risk to human health.

Fine particulate pollution is a mix of solid or liquid particles suspended in the air – smaller than a strand of human hair – that can be present even in air that looks clean, according to the EPA. These pollutants are considered the most dangerous forms of air pollution and are linked to asthma, lung and heart disease, and other respiratory health issues.

Popovici said subsequent reports will focus more on the potential of community air quality resources and ways to mitigate environmental injustices.
