(LONDON) — Residents of Delhi woke up to a thick blanket of toxic smog, prompting the city to cancel in-person classes, halt construction and limit traffic, as the Indian capital city’s air-pollution levels surged past 60 times the World Health Organization’s recommended daily maximum.
Government officials warned the 33 million residents of Delhi to stay inside and use air purifiers as the smog increased in severity. The city implemented GRAP 4, the highest stage of pollution-related emergency measures, which kick into effect during “severe” air pollution.
GRAP 4 forbids trucks — except those carrying essential goods — from entering the city and bans construction and demolition projects. The government may also consider programs where only vehicles with license plates ending in odd or even numbers may drive on a given day.
Last week, Delhi’s environment minister announced the addition of over 100 more buses to the city’s fleet in response to the worsening pollution. The Delhi metro also announced it will run 60 extra trips as the city tries to minimize the number of cars on the road.
Most students will attend remote classes, and only half of employees will go into offices. Children and those with respiratory illnesses were advised to minimize any time outdoors.
Delhi’s air-quality index, or AQI, shot up past 1,000 on Monday, more than five times higher than Sarajevo, the second most-polluted major city, according to the Swiss air monitoring company IQAir.
The WHO estimates that air pollution kills 7 million people annually. IQAir has consistently ranked Delhi amongst the world’s most-polluted cities.
Toxic smog in the region gets worse every year as winter sets in and smog from crop-burning, brick kilns and heavy traffic settles for extended periods due to the cold, dense air.
Atishi Marlena Singh, the chief minister of Delhi, blamed the deadly pollution on the national government’s insufficient measures.
“The Central Government is sitting idle. Today, all of north India has been pushed into a medical emergency,” she said at a press conference.
Forecasts predict the air pollution will continue throughout this week.
(LONDON) — Iran launched missiles at Israel on Tuesday in an attack it said was retaliation for a wave of assassinations carried out by Israel over the last several weeks targeting Hezbollah, an Iran-backed, Shiite Muslim political party and militant group based in Lebanon.
Iran has also said the attacks were for Israel’s extensive attacks on Hezbollah, the destruction in Gaza as well as the assassinations of key Hamas and Hezbollah leaders, including Hamas’ political leader Ismail Haniyeh.
Hezbollah has clashed with Israel for decades, going back to Israel’s occupation of southern Lebanon in 1978, according to the Council on Foreign Relations, a New York City-based independent think tank.
Hezbollah and Israel have repeatedly attacked each other, trading fire across the Lebanese-Israeli border for months.
Tuesday’s strike marks the latest development in an intensifying series of attacks in the region.
Here’s a look at the timeline of the recent conflict:
On Oct. 8, 2023, Israel invaded the Palestinian territory of the Gaza Strip. The invasion was in retaliation for Hamas’ terror attack on Israel on Oct. 7, where Hamas killed roughly 1,200 people and around 250 others were taken hostage, according to the Israeli government.
Hezbollah then began renewed attacks on Israel in opposition to the Gaza invasion, and since Oct. 8, the two sides have been trading attacks with increased intensity in recent months.
In Gaza, about 41,638 people have been killed amid Israeli attacks on the region, according to the Hamas-run Gaza Ministry of Health. Hezbollah has said it will continue its attacks against Israel until the Israel Defense Forces withdraw from Gaza.
Hezbollah controls much of the Shiite-majority areas of Lebanon, including parts of the capital, Beirut. Iran has long been known to provide support, training and weapons to the group.
The IDF said that its special operations teams have been operating in southern Lebanon since November. Hezbollah has denied this and says the IDF has not crossed Lebanon’s border.
Cease-fire negotiations to end Israel’s ongoing war in Gaza and return Israeli hostages have stalled after repeated attempts by the U.S. and others to mediate a deal, and Israeli Prime Minister Benjamin Netanyahu has declined a cease-fire proposal concerning its operations in Lebanon.
The conflict intensified with the detonation of Hezbollah communication devices in Lebanon and Syria. Thousands of people were injured and dozens were killed across Lebanon and Syria by remotely detonated pagers on Sept. 17, according to Lebanese officials. ABC News sources confirmed it was an Israeli covert operation.
The Israeli military also ramped up its airstrikes in Lebanon in recent weeks, including striking thousands of apparent Hezbollah targets in southern Lebanon and killing more than 1030 people and injuring thousands more,according to the Lebanese Ministry of Public Health. Israeli officials said they believe about 30 top Hezbollah leaders have been killed.
On Sept. 26, 2024, Iranian Foreign Minister Abbas Araghchi told reporters on the sidelines of the United Nations General Assembly in New York City that Iran “will not remain indifferent in case of a full-scale war in Lebanon.”
Araghchi also warned that Israel’s “crimes will not go unpunished” and said the Middle East region “risks full-scale conflict” if the U.N. Security Council does not “act now to halt Israel’s war and enforce an immediate ceasefire.”
On Sept. 30, the IDF announced it had begun a ground incursion into Lebanon. The IDF described the operations as “limited, localized, and targeted ground raids based on precise intelligence against Hezbollah terrorist targets and infrastructure in southern Lebanon.”
On Oct. 1, Iran launched missiles into Israel. The Islamic Revolutionary Guard Corps (IRGC) said the missile attack was retaliation for different assassinations carried out by Israel.
President Joe Biden said on Oct. 1 that the U.S. is prepared to help Israel defend against the Iranian missile attack.

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.

U.S. Embassy in London, United Kingdom (L. Toshio Kishiyama/Getty Images)
(LONDON) — A suspicious package was discovered outside the United States embassy in London on Friday morning, police said.
The London Metropolitan Police immediately closed Ponton Road outside of the embassy in “an abundance of caution,” according to their statement, before they destroyed it in a controlled explosion.
“We’re aware of speculation online about an incident in the vicinity of the US Embassy in Nine Elms,” the Met Police said. “Cordons are in place in the area as a precaution while officers investigate a suspect package.”
Authorities updated the situation approximately an hour later after reports of a “loud bang” began circulating online.
“We can confirm that the ‘loud bang’ reported in the area a short time ago was a controlled explosion carried out by officers. Enquiries are still ongoing and cordons will remain in place for the time being,” police said.
The U.S. embassy in London moved to a brand-new purpose-built location in January 2018. The 12-story government office — complete with a moat surrounding it — cost approximately $1 billion to construct and was funded entirely from proceeds of sale from other U.S. government property in London, according to the U.S. government.
