2025 ‘Doomsday Clock’: This is how close we are to self-annihilation, scientists say
(WASHINGTON) — Scientists and global leaders revealed on Tuesday that the “Doomsday Clock” has been reset to the closest humanity has ever come to self-annihilation.
For the first time in three years, the Bulletin of the Atomic Scientists moved the metaphorical clock up one second to 89 seconds before midnight, the theoretical doomsday mark.
“It is the determination of the science and security board of the Bulletin of Atomic Scientists that the world has not made sufficient progress on existential risks threatening all of humanity. We thus move the clock forward,” Daniel Holz, chair of the organization’s science and security board, said during a livestreamed unveiling of the clock’s ominous new time.
“In setting the clock closer to midnight, we send a stark signal,” Holz said. “Because the world is already perilously closer to the precipice, any move towards midnight should be taken as an indication of extreme danger and an unmistakable warning. Every second of delay in reversing course increases the probability of global disaster.”
For the last two years, the clock has stayed at 90 seconds to midnight, with scientists citing the ongoing war in Ukraine and an increase in the risk of nuclear escalation as the reason.
Among the reasons for moving the clock one second closer to midnight, Holz said, were the further increase in nuclear risk, climate change, biological threats, and advances in disruptive technologies like artificial intelligence.
“Meanwhile, arms control treaties are in tatters and there are active conflicts involving nuclear powers. The world’s attempt to deal with climate change remain inadequate as most governments fail to enact financing and policy initiatives necessary to halt global warming,” Holz said, noting that 2024 was the hottest year ever recorded on the planet.
“Advances in an array of disruptive technology, including biotechnology, artificial intelligence and in space have far outpaced policy, regulation and a thorough understanding of their consequences,” Holz said.
Holtz said all of the dangers that went into the organization’s decision to recalibrate the clock were exacerbated by what he described as a “potent threat multiplier”: The spread of misinformation, disinformation and conspiracy theories “that degrade the communication ecosystem and increasingly blur the line between truth and falsehood.”
What is the Doomsday Clock?
The Doomsday Clock was designed to be a graphic warning to the public about how close humanity has come to destroying the world with potentially dangerous technologies.
The clock was established in 1947 by Albert Einstein, Manhattan Project director J. Robert Oppenheimer, and University of Chicago scientists who helped develop the first atomic weapons as part of the Manhattan Project. Created less than two years after the United States dropped atomic bombs on Hiroshima and Nagasaki, Japan, during World War II, the clock was initially set at seven minutes before midnight.
Over the past seven decades, the clock has been adjusted forward and backward multiple times. The farthest the minute hand has been pushed back from the cataclysmic midnight hour was 17 minutes in 1991, after the Strategic Arms Limitation Treaty was revived and then-President George H.W. Bush and Soviet President Mikhail Gorbachev announced reductions in the nuclear arsenals of their respective countries.
For the past 77 years, the Bulletin of the Atomic Scientists, a nonprofit media organization comprised of world leaders and Nobel laureates, has announced how close it believes the world is to collapse due to nuclear war, climate change and, most recently, the COVID-19 pandemic.
(LONDON) — The Israel Defense Forces continued its intense airstrike and ground campaigns in Gaza — particularly in the north of the strip — and in Lebanon, with Israeli attacks on targets nationwide including in the capital Beirut. The strikes form the backdrop for a fresh diplomatic push by the White House ahead of President-elect Donald Trump’s return to the Oval Office in January.
Tensions also remain high between Israel and Iran after the former launched what it called “precise strikes on military targets” in several locations in Iran following Tehran’s Oct. 1 missile barrage.
US envoy en route to Lebanon for cease-fire talks, official says
U.S. envoy Amos Hochstein is on his way to Lebanon for talks on a cease-fire between Hezbollah and Israel, an official familiar with the plans confirmed to ABC News.
Hochstein left from the U.S. for Lebanon on Monday, the official said.
Israel is getting close to being ready to agree to the U.S.-backed cease-fire proposal, which is very similar to the proposal that was floated by the U.S. at the end of September. The U.S. needs to see how Hezbollah feels about this proposal, which is what Hochstein aims to do during his trip, according to the official.

US sanctions entity, 3 individuals tied to West Bank violence
The State Department said Monday it is sanctioning three individuals and one entity for allegedly undermining “peace, security, and stability in the West Bank.”
The department accuses the entity, Eyal Hari Yehuda Company LTD, of having supported Yinon Levi, an Israeli settler who was sanctioned by the Biden administration over accusations of attacks and harassment against Palestinians earlier this year.
The three impacted individuals are Itamar Levi, Shabtai Koshlevsky and Zohar Sabah, the State Department said. Itamar Levi, the brother of Yinon Levi, is being designated for his role as the owner of the aforementioned company, while Koshlevsky is accused of holding a leadership position at Hashomer Yosh, an Israeli nongovernmental organization that provides material support to U.S.-designated outposts in the West Bank and was sanctioned in August of this year.
Sabah is accused of engaging “in threats and acts of violence against Palestinians, including in their homes” as well as “a pattern of destructiveness targeting the livestock, grazing lands and homes of local Palestinians to disrupt their means of support,” the State Department said in a press release.

Hamas denies that leaders relocated from Qatar to Turkey
Hamas denied reports in Israeli media that its leadership has relocated from Qatar to Turkey amid a breakdown in Doha-supported cease-fire talks earlier this month.
Hamas dismissed the news reports as “rumors” spread by Israeli authorities in a statement posted to its official website.
Qatar told Israel and Hamas earlier this month it could not continue to mediate cease-fire and hostage release talks “as long as there is a refusal to negotiate a deal in good faith.”
Doha is under U.S. pressure to expel Hamas leaders. A senior administration official told ABC News earlier this month that the group’s “continued presence in Doha is no longer viable or acceptable.”

Gaza death toll nears 44,000, health officials say
The Hamas-run Gaza Health Ministry said Monday that 43,922 people have been killed in Israeli attacks since Oct. 7, 2023, with nearly 104,000 more injured.
Israeli airstrikes killed at least 96 people and wounded at least 60 in Gaza through the weekend, officials said. The dead included 72 people in north Gaza and more than 20 from other areas of the strip.
Most of those killed were displaced women and children sheltering in residential buildings in the northern town of Beit Lahiya, officials said.
Beit Lahiya is at the heart of the Israel Defense Forces’ recent northern offensive, which has been accompanied with sweeping evacuation orders and spiking civilian casualties.

Hezbollah positive on US cease-fire proposal, reports say
Hezbollah responded positively to the U.S.-proposed cease-fire deal between Israel and Lebanon, Israeli and Lebanese media reported Monday.
U.S. special envoy for Lebanon Amos Hochstein is expected to arrive in Beirut on Tuesday to discuss the proposal before heading to Israel to speak with leaders there.
The proposal is reportedly based on the United Nations Security Council’s resolution 1701 that sought to end the last major cross-border conflict in 2006.
That deal ordered Hezbollah to withdraw all military units and weapons north of the Litani River, which is around 18 miles north of the Israeli border. The resolution also prohibited Israeli ground and air forces from crossing into Lebanese territory.
Israeli leaders have demanded open-ended freedom to act against threats in Lebanon, a stipulation reportedly opposed by Hezbollah and Lebanese leaders.

Hezbollah media relations chief killed in Israeli strike
Mohammed Afif, Hezbollah’s media relations chief, was killed in an Israeli strike Sunday, Hezbollah confirmed.
The strike on central Beirut partially collapsed a building and injured three others, according to the Lebanese Ministry of Health.
The Israel Defense Forces also confirmed Afif’s death. In a statement, the IDF said he joined Hezbollah in the 1980s and went on to become a “central and veteran figure in the organization who greatly influenced Hezbollah’s military activity.”
Citing one particular incident, the statement claimed that he had played a key role in the drone attack on Israel Prime Minister Benjamin Netanyahu’s home in Caesarea in October.

Pope calls for investigation to determine whether Israeli attacks on Gaza are ‘genocide’
Pope Francis, in an upcoming book to be released ahead of his 2025 jubilee, called for an investigation to determine whether Israel’s actions in Gaza constitute genocide, according to the Vatican.
“In the Middle East, where the open doors of nations like Jordan or Lebanon continue to be a salvation for millions of people fleeing conflicts in the region: I am thinking above all of those who leave Gaza in the midst of the famine that has struck their Palestinian brothers and sisters given the difficulty of getting food and aid into their territory,” he wrote in a passage released by the Vatican.
“According to some experts, what is happening in Gaza has the characteristics of a genocide,” the pope wrote. “It should be carefully investigated to determine whether it fits into the technical definition formulated by jurists and international bodies.”
(LONDON) — The Ukrainian Defense Ministry’s Main Directorate of Intelligence said on Monday that at least 30 North Korean soldiers were killed and wounded in weekend battles in Russia’s western Kursk region, prompting commanders to send reinforcements to frontline units.
“North Korean army units are being re-equipped after losses in assaults” around the villages of Plekhovo, Vorozhba and Martynovka in the Kursk region, the GUR wrote in a post to its official Telegram channel.
On Dec. 14 and 15, the GUR said, “units of the DPRK army suffered significant losses — at least 30 soldiers were killed and wounded,” using the acronym for the country’s official name of the Democratic People’s Republic of Korea.
At least three North Korean troops went missing around the village of Kurilovka in Kursk, the post added.
“Due to losses, the assault groups are being replenished with fresh personnel, in particular from the 94th separate brigade of the DPRK army, to continue active combat operations in the area,” the GUR wrote.
Pyongyang is believed to have sent up to 12,000 troops to Russia in recent months, according to a November briefing by Pentagon spokesperson Maj. Gen. Pat Ryder. Their focus is believed to be the Kursk region of western Russia, where Ukrainian forces seized ground in a surprise August offensive.
Sources told ABC News in November that North Koreans may be among the approximately 50,000 troops being readied for a significant counteroffensive in Kursk.
Russian leaders have said they will not consider any peace talks while Kursk remains partially occupied, though officials in Kyiv frame their retention of Russian territory as important negotiating leverage.
North Korea’s provision of troops marked a new level of cooperation between Moscow and Pyongyang. The two neighbors have drawn closer since Russia’s invasion of Ukraine in 2022, with North Korea already providing Moscow with artillery munitions and ballistic missiles.
Ukrainian President Volodymyr Zelenskyy said on Saturday that Kyiv has “preliminary data that the Russians have begun to use North Korean soldiers in their assaults — a significant number of them.”
“The Russians include them in combined units and use them in operations in the Kursk region,” Zelenskyy said in a statement posted to his Telegram page. “So far, only there. But we have information suggesting their use could extend to other parts of the frontline. There are also already noticeable losses in this category.”
“We will defend ourselves, including against these North Koreans,” Zelenskyy added. “And we will continue to act in coordination with all our partners to stop this war — to stop it decisively, with guaranteed peace.”

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.
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.
