At least 5 dead in ‘terrorist attack’ on aerospace facility in Turkey, officials say

(DAMASCUS, SYRIA) — Rebel forces in Syria are building a transitional government after toppling the regime of President Bashar Assad in a lightning-quick advance across the country.

Meanwhile, the ceasefire in Lebanon is holding despite ongoing Israeli airstrikes on Hezbollah targets, which Israeli officials say are responses to ceasefire violations by the Iranian-backed militant group. The Israel Defense Forces continues its intense airstrike and ground campaigns in Gaza.

Tensions also remain high between Israel and Iran after tit-for-tat long-range strikes in recent months and threats of further military action from both sides.

64 patients at Kamal Adwan Hospital still facing relentless bombing

The Kamal Adwan Hospital has been facing relentless and continuous bombing injuring more people in the building.

“The third floor was set on fire, and the water tank was destroyed. The intensive care unit was also targeted while the patients were inside. There were terrifying sounds in the hospital courtyard, and we saw a military vehicle advancing towards the hospital. Barrels were placed, and three of them exploded, causing panic and terror in the hospital,” Dr. Hussam Abu Safia, director of the hospital, told ABC News.

“Drones are constantly dropping bombs on the hospital. Anyone moving in the hospital risks being injured or killed. So far, there is no electricity, water or oxygen at all,” the director said.

Israel will occupy Gaza Strip, defense minister says

Israel will have security control over the Gaza Strip, effectively occupying it, Defense Minister Israel Katz said in a post on X Tuesday.

“After we defeat Hamas’ military and governmental power in Gaza, Israel will have security control over Gaza with full freedom of action, just as in Judea and Samaria,” Katz said.

“We will not allow any terrorist organization against Israeli communities and Israeli citizens from Gaza. We will not allow a return to the reality of before October 7th,” Katz said.

Katz’s predecessor, Yoav Gallant, repeatedly insisted that Israel wanted to avoid the reoccupation of the Gaza Strip.

Ceasefire deal ‘possible’ if Israel does not add new conditions, Hamas says

Amid reports that a ceasefire agreement between Hamas and Israel may be edging closer, Hamas said a “prisoner exchange is possible if the occupation stops putting new conditions.”

More than 45,000 people were killed and over 100,000 injured in Gaza since Oct. 7, 2023, according to the Hamas-run Health Ministry

Over 90% of Gaza’s 2.1 million people have been displaced, according to the United Nations Human Rights Office.

HTS leader criticizes Israeli incursion, occupation

Hayat Tahrir al-Sham head Ahmed al-Sharaa — also known by his nom de guerre Abu Mohammed al-Jolani — told The Times in a new interview that the transitional government in Damascus does “not want any conflict, whether with Israel or anyone else.”

Israel is continuing airstrikes across Syria and has occupied parts of a buffer zone — demilitarized in a 1974 bilateral deal — running between the two nations. Israeli leaders say their military operations are intended to prevent “extremists” from launching attacks into Israel.

But Sharaa said the new administration “will not let Syria be used as a launchpad for attacks.”

“The Syrian people need a break, and the strikes must end and Israel has to pull back to its previous positions,” he added.

Sharaa has asked the international community to pressure Israel to stop its strikes, withdraw from the buffer zone and respect the 1974 agreement.

‘Massive’ Damascus graves could hold 100,000 bodies, NGO says

Mouaz Moustafa, the head of the U.S.-based Syrian advocacy organization, the Syrian Emergency Task Force, told ABC News there are believed to be well over 100,000 bodies in a “massive” burial site discovered 25 miles north of Damascus.

Moustafa told ABC News from the Syrian capital that the site in al-Qutayfah consists of “massive graves” where “lines or trenches were 6 to 7 meters deep, 3 to 4 meters wide and 50 to 150 meters long.”

“In my conversation with the gravediggers, they told me that four tractor trailer trucks each carrying over 150 bodies came twice a week from 2012 until 2018,” Moustafa said.

“The bulldozer excavator driver described how intelligence officers forced workers to use the bulldozer to flatten and compress the bodies to make them fit and easier to bury before digging the next line or trench,” he added.

The mass grave contained men, women, children and the elderly “tortured to death” by former President Bashar Assad’s regime, Moustafa said.

The overthrown president was in power from 2000 to his ousting on Dec. 8. In his first statement since fleeing Syria, Assad on Monday blamed a “terrorist onslaught” for his defeat. His toppling marked the end of a 14-year conflict between Damascus and a collection of rebel groups.

Opposition groups and rescue workers are still uncovering evidence of the regime’s human rights abuses. SETF believes it has identified three other mass graves so far, as well as two “smaller ones,” Moustafa said.

Israel to have ‘full freedom of action’ in Gaza after war, minister says

Israel “will have security control over Gaza with full freedom of action” after the fighting in the devastated Palestinian territory ends, Israeli Defense Minister Israel Katz said in a post to X on Tuesday.

Katz added that Israeli access to the strip will be comparable to its access to the occupied West Bank, which is nominally controlled by the Palestinian Authority but in coordination with Israel.

“We will not allow any terrorist organization against Israeli communities and Israeli citizens from Gaza,” Katz wrote. “We will not allow a return to the reality of before Oct. 7.”

Prime Minister Benjamin Netanyahu’s government has faced domestic and international criticism for its failure to present a clear vision for post-war Gaza beyond the destruction of Hamas as a ruling force.

President Joe Biden is among the world leaders that have warned Israel against any post-war occupation of Gaza or permanent displacement of Palestinians.

State Department: Search for Tice still possible without team on the ground

The State Department’s lack of boots on the ground in Syria isn’t interfering in its efforts to track down missing American journalist Austin Tice, spokesperson Matthew Miller contended on Monday.

The department has had “more than one communication” with rebel group HTS “over the past week,” he told reporters. It was also in touch with other groups, like the White Helmets, that were helping with the search, he said.

“We feel that right now we are able to get good information,” he said.

Tice, an American freelance journalist and Marine Corps veteran, was kidnapped while reporting in Syria more than a decade ago.

In a recent letter to Israeli Prime Minister Benjamin Netanyahu obtained by ABC News, Tice’s family “urgently” asked the Israelis to pause their strikes in a neighborhood in Damascus where they believe he may be held prisoner and to deploy assets to the area to help search for him.

“I’m going to be looking for help anywhere I can, and what I’ve learned in 12 years and four months is go to the top first,” Tice’s mother, Debra Tice, told reporters on Monday when asked about the outreach.

“I think it would be polite to say the least, that perhaps they’re not bombing as people are trying to clear the prison. That would be my first suggestion,” she added.

ABC News has reached out to the prime minister’s office for comment.

Israeli defense minister expresses optimism for ceasefire deal

Israeli officials are expressing optimism about the prospects of a ceasefire deal in Gaza.

“We are closer to a deal than in any other point since the previous deal, the matter is top priority,” Israeli Defense Minister Israel Katz said while addressing the Knesset on Monday, according to the spokesperson of the foreign affairs and security committee.

The remarks come after Mossad chief David Barnea traveled to Doha, Qatar, last week for ceasefire negotiations.

Assad says he fled Syria after drones attacked Russian air base

Former Syrian President Bashar Assad on Monday released his first statement since the collapse of his regime, posting a statement to the presidency’s official Telegram channel.

“My departure from Syria was neither planned nor did it occur in the final hours of the battles,” Assad said. “As terrorist forces infiltrated Damascus, I moved to Latakia in coordination with our Russian allies to oversee combat operations.”

“Upon arrival at the Khmeimim air base that morning, it became clear that our forces had completely withdrawn from all battle lines and that the last army positions had fallen,” the statement continued.

“As the field situation in the area continued to deteriorate, the Russian military base itself came under intensified attack by drone strikes.”

“With no viable means of leaving the base, Moscow requested that the base’s command arrange an immediate evacuation to Russia,” Assad wrote.

“This took place a day after the fall of Damascus, following the collapse of the final military positions and the resulting paralysis of all state institutions,” he added.

Gaza death toll passes 45,000, officials say

A series of Israeli airstrikes across Gaza over the weekend and into Monday morning pushed the total death toll in the strip since Oct. 7, 2023, to more than 45,000 people, according to data from the Health Ministry in the Hamas-run territory.

Per ministry figures, more than 2% of Gaza’s total pre-war residents of 2.23 million people have been killed in 14 months of conflict with Israel.

Israel has ‘no interest’ in Syria conflict, Netanyahu says as strikes continue

Israeli Prime Minister Benjamin Netanyahu said Sunday that his nation has no interest in conflict with the incoming Syrian government, though indicated that Israeli airstrikes and occupation of Syrian territory will continue.

“We have no interest in a conflict with Syria,” Netanyahu said in a statement. “We will determine Israeli policy regarding Syria according to the reality on the ground.”

“I recall that for decades Syria was an active enemy state toward Israel,” he said. “It has attacked us repeatedly.”

Speaking of former President Bashar Assad’s close ties with Iran and its proxies, Netanyahu continued, “It allowed others to attack us from its territory. It allowed Iran to arm Hezbollah through its territory.”

The prime minister issued the statement after another night of heavy airstrikes across Syria. The Syrian Observatory for Human Rights said Monday there have been around 473 Israeli airstrikes on the country since Assad’s fall on Dec. 8.

“Over the course of several days, we have destroyed the capabilities that the Assad regime took decades to build,” Netanyahu said. “We have also struck the weapons supply routes through Syria to Hezbollah.”

Netanyahu said he and Defense Minister Israel Katz had instructed the Israel Defense Forces “to thwart the potential threats from Syria and prevent terrorist elements from taking control close to our border,” a reference to Israeli occupation of a buffer zone between the two nations established in a 1974 peace deal.

“We are committed to preventing the rearming of Hezbollah,” Netanyahu said. “This is a prolonged test for Israel, which we must meet, and which we will meet. I unequivocally declare to Hezbollah and to Iran: In order to prevent you from attacking us, we will continue to take action against you as necessary, in every arena and at all times.”

Over the weekend, Netanyahu’s government also approved a plan to double the territory of the Golan Heights, which has been occupied by Israel since 1967 but is still recognized as Syrian territory by the vast majority of the international community.

“We will continue to hold onto it, cause it to blossom and settle in it,” Netanyahu said.

Israel unilaterally annexed the strategic area — which overlooks Damascus from the southwest — in 1981. The U.S. recognized Israeli sovereignty over the region in 2019.

US embassy tells Americans to leave ‘volatile’ Syria

The U.S. Embassy in Damascus — which suspended operations in 2012 — said in a Monday post to X that the “security situation in Syria continues to be volatile and unpredictable with armed conflict and terrorism throughout the country.”

U.S. citizens, it said, “should depart Syria if possible. U.S. citizens who are unable to depart should prepare contingency plans for emergency situations and be prepared to shelter in place for extended periods.”

U.S. officials have said they are in touch with the most prominent rebel groups now building a transition government after toppling former president Bashar Assad’s regime, but the eventual shape of U.S.-Syrian relations remains unclear.

Hayat Tahrir al-Sham — the most prominent of the rebel groupings — has roots in al-Qaeda and is still listed as a terrorist organization in the U.S. and European Union. Its leader, Ahmed al-Sharaa, better known by his nom de guerre Abu Mohammed al-Jolani, is still the subject of a $10 million U.S. bounty.

The U.S. government “is unable to provide any routine or emergency consular services to U.S. citizens in Syria,” the embassy said. “U.S. citizens in Syria who are in need of emergency assistance to depart should contact the U.S. Embassy in the country they plan to enter.”

The embassy urged citizens in Syria to be “prepared to shelter in place should the situation deteriorate” and to ensure access to all required travel documents.

Netanyahu says he spoke with Trump on Syria

Prime Minister Benjamin Netanyahu on Sunday night released a video in Hebrew addressing Israel’s actions in Syria. He says he discussed this with President-Elect Trump “last night.” He called it a “very friendly, very warm and very important conversation,” and said they spoke about “the need to complete Israel’s victory,” as well as freeing the hostages in Gaza.

On Syria, Netanyahu said he has instructed the Israel Defense Forces “to thwart potential threats from Syria, and to prevent terrorist elements from taking over near our border.” He also said the IDF’s airstrikes in Syria have destroyed “capabilities that the Assad regime had built over decades,” as well as the “arms supply routes from Syria to Hezbollah.”

Netanyahu said Israel has “no interest in confronting Syria” but also said Israel will continue to act to stop Hezbollah from rearming “as much as necessary, in every arena and at any time.”

(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.

Study finds use of renewable energy sources reduces risk of blackouts

The Texas freeze of 2021 knocked out power for more than 10 million people, leaving some without heat for days. In the aftermath of the storm, Texas Gov. Greg Abbott told a national news network that “Wind and solar got shut down.” He added, “They were collectively more than 10% of our power grid, and that thrust Texas into a situation where it was lacking power on a statewide basis.”

However, in the aftermath, a research study found that renewable energy sources (RES) weren’t to blame. Instead, the researchers found that Texas “failed to sufficiently winterize its electricity and gas systems after 2011.”

Other blackouts have also been blamed on RES, including the 2016 blackout in South Australia and a 2019 outage in the U.K., both of which involved disruptions to wind farms.

Now, according to a new study from The University of Tennessee, grids with higher renewable energy penetration are actually less vulnerable to blackouts than those more reliant on traditional, non-renewable sources.

The analysis found that as the proportion of renewable energy in the grid increases, the intensity of blackouts — measured by the number of affected customers and the length of outages — decreases. This finding challenges the notion that renewable energy inherently makes power grids more fragile.

The researchers analyzed over 2,000 blackouts across the U.S., looking specifically at how renewable energy levels and various weather patterns influenced outage severity. They discovered that high levels of renewables didn’t contribute to an increase in weather-related blackouts.

In grids where renewables made up more than 30% of the energy supply, blackout events were generally less intense and shorter in duration. This trend held even during extreme weather, like high winds and storms, which can place heavy demands on power systems.

Researchers say they’ve devised the perfect placement for EV chargers

When you buy a gas-powered car, you rarely worry about where to fill it up. That’s because gas stations are everywhere. A 2022 McKinsey survey found that more than 40% of prospective electric vehicle (EV) buyers want that same degree of convenience when it comes to public charger availability for EVs.

Engineers at Cornell University say they have devised a solution for where to place EV charging stations so they are convenient for drivers and profitable for companies.

Using Bayesian optimization, a mathematical method that efficiently analyzes complex data to achieve these results, the research team discovered that for urban areas that it’s best to install an equal percentage of medium-speed and fast chargers. And because motorists use different speed chargers for different reasons, the researchers said it is essential to consider how they are being used when placing them around town.

For example, the engineers found that fast charging is more important at grocery stores when consumers are only inside for 20 minutes. Work and home charging stations should be medium speed because drivers usually park for hours at a time at those locations.

The researchers say their approach can boost investor returns by 50% to 100% compared to random placement strategies.

The team simulated the behavior of 30,000 vehicles over 113,000 trips in the Atlanta region, considering various traffic patterns and driver decisions. This method allowed them to determine optimal charging station placements.

Yeuchen Sophia Liu, the study’s lead author, told the Cornell Chronicle that, “Placing publicly available charging stations around cities sounds like a simple thing, but mathematically, it’s actually very hard.”

She added, “Economically strategic placement of charging stations could play a pivotal role in accelerating the transition to zero-emission vehicles.”

Nearly 40% of the world’s trees face extinction, according to new assessment

Climate change, deforestation, invasive pests and disease all threaten to permanently wipe out nearly 40% of the earth’s trees, according to a new assessment by the International Union for the Conservation of Nature (IUCN).

The organization, comprised of 1,400 member organizations worldwide and 16,000 experts, said more than one in three tree species across 192 countries is now facing extinction, especially trees found on islands.

development and agriculture, as well as the other threats faced by tree species across the globe.

Since 1964, the IUCN has hosted its “Red List,” a database of threatened species from around the world. The research group found that 16,425 of the 47,282 tree species on their list are at risk of extinction — more than 2,000 of which are used for medicines, food, and fuels.

“Trees are essential to support life on Earth through their vital role in ecosystems, and millions of people depend upon them for their lives and livelihoods,” said Grethel Aguilar, IUCN director general, in a statement.

According to their analysis, “the number of threatened trees is more than double the number of all threatened birds, mammals, reptiles and amphibians combined.”

The group is calling for more habitat protection and restoration to protect these species and the creation of seed banks and botanical gardens to ensure they don’t disappear forever.

“The significance of the Global Tree Assessment cannot be overstated, given the importance of trees to ecosystems and people. We hope this frightening statistic of one in three trees facing extinction will incentivize urgent action and be used to inform conservation plans,” said Eimear Nic Lughadha from the Royal Botanic Gardens, in a statement.

Report finds climate change increased heat deaths among older adults by 167%; worsened food security

The health and economic costs of climate change are rising worldwide, according to the newly released 2024 Lancet Countdown, a yearly report hosted by University College London and involving more than 300 researchers.

According to the report, “Of the 15 indicators monitoring climate change-related health hazards, exposures, and impacts, ten reached concerning new records in their most recent year of data.”

With global communities facing an additional 50 days of “dangerous heat,” heat-related deaths among older adults increased by a record-breaking 167% in 2023 compared to the 1990s, according to the report’s findings.

In addition to the heat impact, the Lancet report found that climate change is significantly worsening food insecurity, with 151 million more people facing shortages compared to previous decades. And more than 3 million people died in 2021 because of air pollution and fine particulate matter.

The researchers also found that global extreme weather costs have increased by 23% from 2010-14 to 2019-23, amounting to $227 billion annually.
