Protesters gather at impeached South Korean president’s residence, as arrest warrant nears expiration

(NEW YORK) — A once long-dormant volcano in Iceland is erupting again and impacting activity in a populated region nearby.

The volcano, on the Reykjanes peninsula in southwestern Iceland, began erupting at Sundhnukar on Wednesday night and peaked at about 2 a.m. local time Thursday, according to the Icelandic Meteorological Office. It has prompted evacuations at the Blue Lagoon, an iconic tourist destination, and the nearby town of Grindavik.

West Iceland’s volcano is a rift activity volcano, which involves the earth being pulled apart in two different directions through the Mid-Atlantic Ridge, rather than a cone erupting magma through a central pipe, Thomas Algeo, a professor of earth sciences at the University of Cincinnati, told ABC News. The style of eruption is “much less dangerous, because most of the activity involves slow moving basaltic lava flows,” he added.

“It’s a style of volcanic activity that is effusive, slow flowing, not violently eruptive, like would be the case with a subduction zone volcanic system” Algeo said.

The fissure that was created on Wednesday night stretched about 1.8 miles long, according to the country’s meteorological office. This is the volcano’s seventh eruption this year, according to Iceland’s Department of Civil Protection and Emergency Management.

These types of eruptions are “spectacular” sights, because once a fissure opens up, a large supply of magma oozes out, Tobias Fischer, director of the Volatiles Laboratory at the University of New Mexico, told ABC News.

The eruption activity is “typical” for these types of systems, said Shawn Willsey, a geology professor College of Southern Idaho who has been conducting livestream tours using drones above the lava flows on YouTube. Once the lava erupts, the pressure is relieved and magma starts to fill into the shallow storage zone below — repressurizing the system and setting the stage for the next eruption, Willsey said.

“It’s known that this region goes through these episodes where there are a lot of these eruptions,” said Fischer, who has flown drones into eruption gas clouds to collect samples and analyze the composition of the carbon for his research.

By Thursday afternoon, the lava had reached the parking lot of the Blue Lagoon and consumed a service building, The Associated Press reported. There is no danger to the area, and the flights out of the Keflavik International Airport have not been affected, according to the civil protection agency.

Gas emitted from the eruption is expected to move south and out to sea, according to emergency officials.

Video taken from Grindavik show rivers of fast-moving lava flowing from the rift zones, where the lava can be seen spewing from the ground.

The ongoing eruption is “significantly smaller” than the eruption that took place in August, according to the meteorological agency.

Iceland is known as a “hot spot” for volcanic activity, Algeo said.

There are 32 active volcano systems in the region spread across three rift zones spread to the north, south and west — all part of the Mid-Atlantic Ridge, a mountain range that mostly runs down the middle of the Atlantic Ocean.

But in Iceland, the mountain range comes above the ocean certain due to “an excessively high production of magma in that area,” Algeo said.

Iceland’s western rift zone, also known as the Reykjanes-Langjökull rift zone, was active prior to the 13th century. These types of eruptions tend to have every 1,000 or so years, Fischer said,

“The big question is, is this going to continue on for centuries?” Willsey said.

In 2021, the volcano in western Iceland became active again. There have been 10 eruptions since there, seven of which have occurred in 2024, according to Icelandic officials said.

During the last 800 years, the majority of volcanic activity were in the north and east volcanic zones — both lightly populated regions, Algeo said. But western Iceland, which includes the capital of Reykjavik, is highly populated.

“They were in a nice little valley up in the mountains, and so that lava was pretty well contained,” Willsey said, adding that lava in those regions are “tourist-friendly” eruptions that can be enjoyed with little threat.

The recent eruptions in western Iceland have damaged infrastructure and property and forced residents to relocate, according to AP.

Previous eruptions throughout history have caused destruction in Iceland, Algeo said.

A large eruption that took place in 1783, known as the Laki eruption, is one of the worst in recorded history. It spewed so much toxic volcanic gasses across the landscape that it killed off most of the local farm animals and reduced the harvest, leading to starvation for about 25% of the population, Algeo said.

Eruptions on the Reykjanes peninsula in December 2023 triggered toxic gas warnings, causing emergency managers to fear that the pollution would spread to the capital.

A disruptive eruption at the Eyjafjallajokull volcano in 2010 disrupted trans-Atlantic air travel for months due to ash being spewed into the air.

(BEIT LAHIA, Gaza) – Health officials in Gaza say there is only one hospital remaining that is providing humanitarian aid services in the northern part of the strip amid the ongoing Israel-Hamas war.

In early October, Israel Defense Forces reportedly ordered evacuations of several regions in the north of Gaza, doctors at the hospitals told ABC News, including Beit Hanoun, Jabalia and Beit Lahia, as they work to surround Hamas fighters who are allegedly in the area.

Dr. Hussam Abu Safiya, director of Kamal Adwan Hospital in Beit Lahia, said in a recorded message shared over the weekend on an X account by the director general of the Hamas-run Gaza Ministry of Health that his hospital is “currently the only hospital still providing humanitarian services in northern Gaza.”

Between 50,000 and 75,000 residents are estimated to remain in northern Gaza, according to the United Nations Office for the Coordination of Humanitarian Affairs.

In additional comments Sunday, sent via a WhatsApp group the Gaza Ministry of Heath uses to share updates with the media, Safiya said there are currently 400 civilians inside Kamal Adwan Hospital, including babies in the neonatal unit who are in incubators and in need of oxygen. He further said that despite orders from the IDF to evacuate Kamal Adwan Hospital, there is no way to safely evacuate patients from the hospital.

“We have repeatedly requested assistance and have openly invited [Israeli forces] to see for themselves the internal workings of our hospitals so that we may continue to serve our population without fear of attack and death. These calls were rejected,” Safiya said in Sunday’s comments. “We also call on the world to witness, that if Kamal Adwan Hospital is decommissioned, there will be no way of preserving conditions of life to the remaining 75,000+ civilians in north Gaza.”

ABC News has not been able to confirm if and when Israeli forces were invited to enter Kamal Adwan Hospital, as Safiya claims, nor when the invitation was allegedly rejected.

Safiya also said that Kamal Adwan Hospital has been the target of IDF attacks as recently as Sunday.

“Direct attacks on the hospitals began with no warnings and no civilian protection permitted by the occupation, in the way of normal procedures expected in a combat zone,” he said in the Sunday message to reporters. “[International Committee of the Red Cross] and other U.N. bodies were consistently denied access to intervene. As a result, significant harm and loss to civilian life and means of preserving life resulted in these attacks on hospitals.”

“Regarding Kamal Adwan Hospital, IDF forces are operating in its vicinity but not within its premises,” the IDF said Monday in response to an ABC News request for comment, adding that the IDF “is unaware of any evacuation order of the hospital.” The IDF response did not address whether they attacked the hospital.

Israel has claimed that Hamas uses hospitals, and networks of tunnels beneath them, as bases to conduct and promote terrorist activity, and U.S. officials have backed this claim. Hamas, however, has repeatedly denied it.

Israeli forces have also insisted that they have tried to limit civilian casualties as much as possible over the course of the war.

The latest update from the Gaza Ministry of Health comes as UNICEF says children in the most northern part of Gaza have been largely unable to receive humanitarian assistance for more than 10 weeks due to the ongoing siege.

More than 96% of women and children in Gaza are currently surviving on a diet of rationed flour, lentils, pasta and canned food, which does not meet their nutritional needs, according to UNICEF.

“Gaza must be one of the most heartbreaking places on earth for humanitarians. Every small effort to save a child’s life is undone by fierce devastation,” UNICEF Communication Specialist Rosalia Bollen said during a press briefing at the Palais des Nations in Geneva on Friday.

“For over 14 months, children have been at the sharp edge of this nightmare, with more than 14,500 children reportedly killed, thousands more injured,” she continued. “As we approach the end of the year, a time when the world strives to celebrate family, peace and togetherness, in Gaza the reality for over a million children is fear, utter deprivation and unimaginable suffering.”

Since Hamas launched its surprise terrorist attack on Israel on Oct. 7, 2023, more than 1,700 Israelis have been killed and more than 8,700 have been injured, according to Israeli officials. In Gaza, more than 45,300 people have been killed, and more than 107,700 people have been injured, according to the Gaza Ministry of Health.

(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.

What caused the extreme flooding in Spain that killed more than 60 people?

The weather phenomenon responsible for the extreme rainfall and flooding in Valencia, Spain, isn’t rare or even uncommon. It was also well forecasted in the days leading up to the storm.

The Mediterranean region, including parts of eastern Spain, is frequently affected by heavy rainfall and significant flash flooding events. This recent disaster saw a year’s worth of rainfall in just eight hours. In September 2019, the same region saw 12 to 18 inches of rain in 48 hours.

What’s responsible for these events is a weather system known as a cut-off low. This happens when a low-pressure area is separated from the primary airflow.

Cut-off lows are common and can happen at any time of the year, anywhere in the world. When there is an extended stretch of cloudy, damp, and dreary weather, this is often related to a cut-off low.

However, the slow-moving nature of a cut-off low can set the stage for devastating extreme rainfall events when it interacts with other favorable factors, like the warm waters of the Mediterranean Sea and nearby mountains. Because it is slow-moving, it can quickly pound areas with relentless rounds of heavy rain, resulting in significant flooding.

In Spain, these weather events are often called a “gota fría,” which translates to “cold drop.” But that term doesn’t tell the whole story. What happened in Valencia wasn’t caused by a sudden cold blast sweeping across the region but by the unique characteristics of a cut-off low.

That’s not to say that cold air in the atmosphere doesn’t play a role in enhancing the precipitation. It does bring more frequent rounds of heavy rain. As the system pushes the colder air over the very warm waters of the Mediterranean Sea, it helps trigger and enhance areas of heavy rain.

Because the low-pressure system moves very slowly, it keeps sending waves of heavy rain over the same areas for an extended period, bringing extreme rainfall totals and catastrophic flash flooding.

The nearby mountains also likely enhanced the precipitation and impacts. Plus, the infrastructure in the Valencia region, like many municipalities, isn’t built to handle this amount of rainfall. Add in all of those factors, and you get catastrophic flash flooding.

What role, if any, does climate change play in these extreme weather events?

Climate attribution science will look at how much worse the rain was because of human-caused emissions, but we know that human-amplified climate change is supercharging the water cycle, bringing heavier rainfall and related flood risks. More intense extreme rainfall events increase the frequency and scale of flash flooding as the influx of water is more than the infrastructure of many municipalities was built to handle.

According to the U.S. Government’s Fifth National Climate Assessment, human-amplified climate change is contributing to increases in the frequency and intensity of the heaviest precipitation events. So, in a way, we are all making it rain more.

Reducing food waste is good for your budget and the planet

We waste a lot of food. According to the U.N., over a billion tons of it are wasted each year globally, most of it from households. Not only does wasting all this food cost the average American family $1,200 a year, but it’s a significant source of greenhouse gas emissions.

The EPA says food waste in the U.S. is equivalent to the greenhouse gas emissions of more than 50 million passenger cars and is responsible for 58% of methane emissions from municipal landfills.

Methane is a particularly potent greenhouse gas because it traps more heat in the atmosphere than carbon dioxide. The U.N. Environment Programme says methane is “responsible for more than 35 percent of the global warming we are experiencing today.”

How does our food waste become methane?

Landfills act like big diaper linings on the ground, so nothing we throw away decomposes into the soil. There’s a barrier preventing it. Our food waste gets sandwiched between all the plastic, metal and non-organic trash, and without oxygen, it mummifies and releases methane. So, every time we throw away leftover food, we create methane and speed up climate change.

There are, however, ways to curb food waste at home. Composting can turn leftovers into fertilizer for your plants and homegrown produce. If you don’t have a garden, you can use a product like the Mill Kitchen Bin to turn your food waste into clean, dry grounds that don’t smell. Those grounds can then be used as part of the composting process at home or given to a local community garden or farm.

The Too Good To Go app is another way of keeping food out of landfills. The service allows people to purchase surprise bags of surplus food from nearby restaurants, bakeries and grocery stores, preventing perfectly edible items from being thrown away. The bags, priced between $5 and $10, are packed with various items that are still good to eat but would have been thrown away.

Understanding food labels can also significantly reduce your waste. The often confusing terms “use by,” “best by,” and “expiration dates” sound similar but mean different things.

A “use by date” is the last date recommended for eating a product while it’s still at its peak quality. After this date, the food might still be safe, but the quality may decline. For perishable items like dairy or meats, it’s often best to follow this date closely, but use your nose and eyes to help determine whether it’s still good.

“Best by” or “best before” dates are about the product’s quality, not safety. It indicates when the food will be at its best flavor or texture. After this date, the food is usually still safe to eat, but it might not taste as good or have the same texture. Often, you won’t even notice a difference.

“Expiration dates” are dates found on products where safety is a concern, like baby formula or certain medications. After this date, the product should not be consumed, as it may not be safe or effective.

Greenhouse gas concentrations reach new record high in 2023

Our planet is facing another unfortunate climate milestone.

According to a new report from the World Meteorological Organization (WMO), carbon dioxide concentrations have increased by more than 11% in just two decades, making 2023 a record for the amount of the greenhouse gas currently in our atmosphere.

The WMO says CO2 is now building up in the atmosphere faster than at any time in human existence. They say massive vegetation fires, which emit greenhouse gases, and El Niño, which can reduce our forests’ ability to absorb CO2 due to drought, contributed to the recent surge. However, the U.N. agency also points out, “The reason behind this decade-long significant increase in CO2 is historically large fossil fuel CO2 emissions in the 2010s and 2020s.”

The WMO began reporting on greenhouse gas emissions in 2006. That year, they found that atmospheric CO2 levels for 2004 were at 377.1 parts per million. Last year, they were recorded at 420 parts per million. That puts CO2 concentrations at 151% above the preindustrial era.

Methane, one of the worst greenhouse gases in terms of global warming, also reached a record level for atmospheric concentrations. It is now 265% higher than preindustrial readings at 1,934 parts per billion.

Because CO2 stays in the atmosphere for 300 to 1,000 years, according to NASA, the WMO is warning that these high levels of greenhouse gases “lock in future temperature increase” even if emissions are cut to net zero.

October record heat made more likely because of climate change

It may be fall, but it feels a lot like summer in much of the country. That has some people wondering: Is climate change responsible for these record-high temperatures? With climate attribution science, we can now answer that question and determine when human-amplified climate change is responsible for extreme weather events and the significance of that impact.

Using advanced computer models, climate attribution science takes a real-world weather event, such as a record high-temperature day or a hurricane, and compares it to the world where human-caused, post-industrial greenhouse gas emissions don’t exist. By comparing what is actually happening with what would have happened without human intervention, science can estimate how likely or severe a weather event has become due to climate change.

Climate Central, a nonprofit climate research and communications organization, uses climate attribution science to provide real-time data that shows “how much climate change influences the temperature on a particular day.” The information is displayed on a global interactive map called the Climate Shift Index.

For example, the Index showed that human-amplified climate change made Sunday’s record high in Tucson, Arizona of 98 degrees at least three times more likely. The same was true for Waco, Texas, which broke a record with 92-degree heat, and Mobile, Alabama, which hit a record 90 degrees.

Extreme heat is the deadliest weather-related hazard in the U.S., with children and adults over 65 being among the most vulnerable to heat-related illnesses and death. And the average number of heat waves that major U.S. cities experience each year has doubled since the 1980s, according to the federal government’s Fifth National Climate Assessment.

How crops will fare with 45% of the US experiencing drought

The U.S. is experiencing the driest fall on record, which could potentially impact the quality of upcoming autumn harvests, experts told ABC News.

About 77% of the mainland U.S. is abnormally dry, and almost half of the country is experiencing drought, according to the U.S. Drought Monitor. The spatial pattern of the dry conditions varies widely across the continent, Josue Medellin-Azuara, a professor of civil and environmental engineering at the University of California Merced, told ABC News.

Improvement in the drought is not expected for most of the South, the Plains and parts of the Upper Midwest due to expected La Nina conditions this winter that would further reinforce the dryness, according to forecasts by the National Oceanic and Atmospheric Administration.

However, a lot of the crops in these regions that harvest in the fall had good growing conditions throughout the summer and are in the process of being harvested, meaning overall output should not be heavily impacted, Joseph Glauber, senior research fellow at the International Food Policy Research Institute and former chief economist for the U.S. Department of Agriculture, told ABC News.

EPA cancels toxic pesticide used in growing produce

The United States Environmental Protection Agency (EPA) said it’s canceling any product containing the pesticide dimethyl tetrachloroterephthalate (DCPA), also known as Dacthal.

According to the EPA, their decision is based on comprehensive scientific studies that indicate potential thyroid toxicity linked to DCPA. The agency says research suggests that exposure to this pesticide during pregnancy can lead to changes in thyroid hormone levels in unborn children. Studies cited by the EPA indicate that these hormonal changes could be associated with various health concerns, including low birth weight, impaired brain development and reduced IQ. That research suggests that these developmental challenges may also have long-term effects on motor skills.

DCPA is used in the industrial farming of broccoli, Brussels sprouts, cabbage and onions. While pregnant women working in agriculture are most at risk, pesticides can travel into neighboring communities via the air and runoff, putting non-agricultural workers at risk as well.

In a press release, EPA’s assistant administrator for the office of chemical safety and pollution prevention, Michal Freedhoff, wrote, “With the final cancellation of DCPA, we’re taking a definitive step to protect pregnant women and their unborn babies. The science showing the potential for irreversible harm to unborn babies’ developing brains, in addition to other lifelong consequences from exposure, demands decisive action to remove this dangerous chemical from the marketplace,” Freedhoff added.
