What are El Niño and La Niña and what's predicted for 2025?
Scientists say that while La Niña conditions could emerge to slightly cool global temperatures in 2025, the planet is still warming at an alarmingly rapid rate.
The past year is certain to be the hottest on record, according to European scientists, and the first to see average global temperatures surpass the Paris Agreement target of 1.5 degrees Celsius above the pre-industrial period.
Soaring temperatures in 2024 were partly boosted by climate conditions known as El Niño (Spanish for “the boy”), according to the World Meteorological Organisation’s data analysis.
In 2025, another phenomenon known as La Niña (Spanish for “the girl”) could emerge to slightly cool global temperatures, meaning it looks unlikely that the 2024 temperature record will be broken next year.
But despite this, 2025 is still likely to be among the three hottest years on record, according to the UK’s weather and climate agency, the Met Office.
What are El Niño and La Niña?
El Niño and La Niña are two opposing climate conditions in the Pacific Ocean that affect the weather across the globe.
Trade winds in the Pacific tend to blow from east to west, pushing warm surface waters towards the western Pacific.
El Niño occurs when these winds weaken or reverse, making the waters in the eastern Pacific – off the coast of the Americas – warmer than normal.
In La Niña periods, the east-to-west trade winds become stronger, pushing warm waters further west towards the coasts of Australia and south-east Asia. This causes cold water to ‘upwell’ or rise from the depths of the ocean, making sea surface temperatures cooler on average, particularly in the Americas.
The episodes happen at irregular intervals every two to seven years, and usually last nine to 12 months.
Both El Niño and La Niña can affect weather patterns across the world. Although each episode is different, La Niña is associated with rainier-than-normal conditions in several parts of the world, such as northern Australia, south-eastern Africa and northern Brazil. It can also make flooding more likely in some regions, and cause a more intense hurricane season.
What are scientists predicting for 2025?
The World Meteorological Organisation (WMO) says La Niña conditions could emerge between November 2024 and February 2025.
But its cooling impact on global temperatures could be “weak and short-lived”, the WMO says.
“Since June 2023 we have seen an extended streak of exceptional global land and sea surface temperature. Even if a short-term cooling La Niña event does emerge, it will not change the long-term trajectory of rising global temperatures due to heat-trapping greenhouse gases in the atmosphere,” WMO Secretary-General Celeste Saulo said.
In fact, meteorologists say the temperature forecasts for 2025 are extremely high considering the probability of La Niña conditions.
“Years such as 2025 which aren’t dominated by the warming influence of El Niño, should be cooler. 2016 was an El Niño year and at the time it was the warmest year on record for global temperature. In comparison to our forecast for 2025 though, 2016 is now looking decidedly cool,” according to Professor Adam Scaife, who leads the UK Met Office’s global forecast for 2025.
Paris Agreement not (yet) breached
It looks likely that 2024 temperatures will for the first time exceed 1.5 degrees Celsius above pre-industrial times, a benchmark set by the 2015 Paris Climate Agreement for the first time.
But passing that threshold for one year is not considered a breach of the Paris threshold. Scientists say that the threshold would need to be breached persistently, over a period as long as 20-30 years.
Some scientists say the link between climate change and the phenomena of La Niña and El Niño is not entirely clear.

Pope Leo says remarks about world being ‘ravaged by a handful of tyrants’ were not aimed at Trump: report
NEWYou can now listen to Fox News articles!
Pope Leo XIV said Saturday that remarks he made this week in which he said the “world is being ravaged by a handful of tyrants” were not directed at President Donald Trump, a report said.
The pope, speaking onboard a flight to Angola during his 10-day tour of Africa, said reporting about his comments “has not been accurate in all its aspects” and his speech “was prepared two weeks ago, well before the president ever commented on myself and on the message of peace that I am promoting,” according to Reuters.
The news outlet cited the pope as saying his comments were not aimed at Trump.
“As it happens, it was looked at as if I was trying to debate the president, which is not in my interest at all,” the pope reportedly said.

Vice President JD Vance later took to X to thank the pope for clearing the record.
“While the media narrative constantly gins up conflict — and yes, real disagreements have happened and will happen — the reality is often much more complicated,” Vance wrote. “Pope Leo preaches the gospel, as he should, and that will inevitably mean he offers his opinions on the moral issues of the day.
“The President — and the entire administration — work to apply those moral principles in a messy world,” he continued. “He will be in our prayers, and I hope that we’ll be in his.”
The vice president’s comments came days after he told Fox News’ Bret Baier on “Special Report” that it would be best for the Vatican to “stick to matters of morality.”
“Let the President of the United States stick to dictating American public policy,” Vance said Tuesday.
Trump last Sunday accused Pope Leo XIV of being “terrible” on foreign policy after the pontiff criticized the U.S.-Israeli war on Iran.
“He talks about ‘fear’ of the Trump Administration, but doesn’t mention the FEAR that the Catholic Church, and all other Christian Organizations, had during COVID when they were arresting priests, ministers, and everybody else, for holding Church Services, even when going outside, and being ten and even twenty feet apart,” Trump wrote in a Truth Social post.
“I don’t want a Pope who thinks it’s OK for Iran to have a Nuclear Weapon.”

During a speech in Cameroon on Thursday, the pope said, “We must make a decisive change of course — a true conversion — that will lead us in the opposite direction, onto a sustainable path rich in human fraternity.
“The world is being ravaged by a handful of tyrants, yet it is held together by a multitude of supportive brothers and sisters.

Bulgaria votes in eighth election in five years
Bulgarians headed to the polls Sunday for the eighth time in five years, with anti-corruption candidate and former president Rumen Radev’s bloc tipped to win.

The European Union’s poorest member has been through a spate of governments since 2021, when large anti-graft rallies brought an end to the conservative government of long-time leader Boyko Borissov.
Eurostat data shows Bulgaria consistently ranks last in the EU by GDP per capita. In 2025, Bulgaria (along with Greece) was at 68% of the EU average.
Radev, who has advocated for renewing ties with Russia and opposes military aid to Ukraine, was president for nine years in the Balkan nation of 6.5 million people.
He stepped down in January to lead newly formed centre-left grouping Progressive Bulgaria, with opinion polls before Sunday’s vote suggesting the bloc could gain 35% of the vote.
The former air force general has said he wants to rid the country of its “oligarchic governance model”, and backed anti-corruption protests in late 2025 that brought down the latest conservative-backed government.
“I’m voting for change,” Decho Kostadinov, 57, told reporters after casting his ballot at a polling station in the capital, Sofia, adding corrupt politicians “should leave — they should take whatever they’ve stolen and get out of Bulgaria”.
Polls are forecasting a surge in voter participation, with more than 3.3 million Bulgarians expected to cast ballots according to the Bulgarian News Agency.
Voting will close at 1700 GMT, with exit polls expected immediately afterwards. Preliminary results are expected on Monday.
‘Preserve what we have’
Borissov’s pro-European GERB party is likely to come second, according to opinion polls, with around 20%, ahead of the liberal PP-DB.
“I’m voting to preserve what we have. We are a democratic country, we live well,” said Elena, an accountant of about 60, who did not give her full name, after casting her vote in Sofia.
Front-runner Radev has slammed the EU’s green energy policy, which he considers naive “in a world without rules”.
He also opposes any Bulgarian efforts to send arms to help Ukraine fight back Russia’s 2022 invasion, though he has said he would not use his country’s veto to block Brussels’ decisions.
Pushing for renewed ties with Russia, Radev denounced a 10-year defence agreement between Bulgaria and Ukraine signed last month – drawing fresh accusations from opponents of being too soft on Moscow.
The ex-president also stoked outrage online for screening images at his final campaign rally of his meetings with world leaders including Russia’s Vladimir Putin.
“We need to close ranks,” he told around 10,000 cheering supporters at the rally, presenting his party as a non-corrupt “alternative to the perverse cartel of old-style parties”.
Borissov, who headed the country virtually uninterrupted for close to a decade, has dismissed suggestions that Radev brings something “new”.
At a rally of his party earlier this week, he insisted GERB had “fulfilled the dreams of the 1990s” with such achievements as the country joining the eurozone this year.
‘No one to vote for’
Radev is aiming for an absolute majority in the 240-seat parliament.
A lack of trust in politics has affected voter turnout, which slumped to 39% in the last election in 2024.
But with Radev rallying voters, high turnout is expected this time, according to analyst Boryana Dimitrova from the Alpha Research polling institute.
Miglena Boyadjieva, a taxi driver of about 55, said she always votes, but the “problem is that there is no one to vote for”.
“You vote for one person and get others. The system has to change,” she told reporters.
Political parties have called on Bulgarians to show up for the polls, also to curb the impact of vote buying.
In recent weeks, police have seized more than one million euros in raids against vote buying in stepped-up operations.
They have also detained hundreds of people, including local councillors and mayors.

How Cheap Drones Are Changing Wars Like the Ones in Ukraine and Iran

One of the biggest takeaways of the war with Iran is that it has proven itself to be a surprisingly capable adversary against the United States. In addition to its willingness to go on the offensive, Iran has forced the U.S. and its regional allies to confront the rise of cheap drones on the battlefield.
Iranian drones, made with commercial-grade technology, cost roughly $35,000 to produce. That is a fraction of the cost of the high-tech military interceptors sometimes used to shoot them down.
Cheap drones changed the war in Ukraine, and they have enabled Iranians to exploit a gap in American defense investments, which have historically prioritized accurate but expensive solutions.
Countering drones has been a major priority for the Pentagon for years, according to Michael C. Horowitz, who was a Pentagon official in the Biden administration. “But there has not been the impetus to scale a solution,” he said.
In just the first six days, the U.S. spent $11.3 billion on the war with Iran. The White House and Pentagon have not provided updated estimates, but the American Enterprise Institute, a conservative-leaning think tank, estimated in early April that the U.S. had spent approximately between $25 and $35 billion on the war, with interceptors driving much of the cost. Many missile defense experts also fear interceptor stockpiles are now running dangerously low.
Here is a breakdown of some of the ways the U.S. and its allies have countered Iran’s drones, and why it can be so costly.
Air-based strikes
In an ideal scenario, an early warning aircraft spots a drone when it is still several hundred miles out from a target, and a fighter jet, like an F-16, is dispatched from a military base. The F-16 can then use Advanced Precision Kill Weapon System (APKWS) II rockets to shoot a drone from about six miles away.

Two to three interceptors fired per drone
These types of defensive air patrols are cost-efficient, but haven’t always been available because of the vast scope of the conflict. Iran has also targeted early warning aircraft that the U.S. needs to detect a drone from that distance, according to NBC News.
The other option for detecting and shooting down drones is a variety of different ground-based detection systems, but these systems are all at a disadvantage, as their ability to spot low-flying drones is limited by the curvature of the earth.
Anti-drone defense systems
One ground-based defense system the U.S. and its allies have built specifically to counter drones at a shorter range is the Coyote. It can intercept drones up to around nine miles away.

The Coyote is significantly cheaper than many of the other ground-based defense systems available to the U.S. and its allies and historically effective at defending important assets. But despite being both effective and cost-efficient, relatively few Coyotes have been procured by the U.S. military in recent years.
When Iran-backed militias launched attacks on U.S. ground troops in the region in 2023 and 2024, there were so few Coyotes available that troops had to shuffle the systems between eight different bases in the region almost daily, according to a report from the Center for a New American Security, a Washington think tank.
Ship-based anti-missile defenses
Many of the longer-range ground-based defense systems the U.S. and its allies can use to combat drones are more expensive, as they are designed to shoot down aircraft and ballistic missiles, not drones. A Navy destroyer’s built-in radar system, for instance, can detect drones from 30 miles away and shoot it down with Standard Missile 2 (SM-2) interceptors. As in the air-based strikes, military protocol stipulates that at least two missiles be fired.

This misalignment between America’s defense systems and current warfighting tactics started after the Cold War, when the anticipated threats were fewer, faster, higher-end projectiles, not mass drone raids.
Iran often launches multiple Shahed-136 drones at a time, given their low price tag. The drones are also programmed with a destination before launch and can travel roughly 1,500 miles, putting targets all across the Middle East within reach.
“This category of lower-cost precision strike just didn’t exist at the time that most American air defenses were developed,” said Mr. Horowitz.
Ground-based anti-missile defenses
The Army’s standard air-defense system is the Patriot. Typically stationed at a military base, it can shoot down a drone from up to around 27 miles away with PAC-3 Missile Segment Enhancement interceptors. Military protocol stipulates that at least two missiles be fired.

Patriot missile defense system
Air defense training teaches service members to prioritize using longer-range defense systems first to “get as many bites at the apple as you can,” but those are the most expensive, said Stacie Pettyjohn, a senior fellow and director of the defense program at the Center for a New American Security.
But a costly defense can still make economic sense to protect a valuable target, especially those that are difficult to repair or replace, such as the nearly $1.1 billion radar at a military base in Qatar and the $500 million air defense sensor at a base in Jordan that were damaged early in the conflict.
Ground-based guns
Finally, there is what one might call a last resort: a ground-based gun. When a drone is about a mile away or less than a minute from hitting its target, something like the Centurion C-RAM can begin rapidly firing to take down the drone.

Even though it is fairly cost-effective, the Centurion C-RAM is not the best option because it has such a short range.
Interceptor drones
There’s also what one might call the future of fighting drones: A.I.-powered interceptor drones. Interceptor drones like the Merops Surveyor can theoretically hunt and take down enemy projectiles from a short range.
A 3-D rendering of a Surveyor drone, which looks like a three-foot tube with wings and a tail. The Merops drone costs approximately $30,000, a little less than a single Iranian Shahed-136.
Merops system: Surveyor drone
Eric Schmidt, the former Google chief executive, founded a company to develop the Merops counter-drone system in conjunction with Ukrainian fighters, who have already been combatting Iranian drones in the war with Russia for years.
The U.S. sent thousands of Merops units to the Middle East after the conflict began, but it is unclear whether they have been deployed. The military set up training on the system in the middle of the war, as reported by Business Insider.
Other attempts to lower the cost-per-shot ratio of taking out a drone have failed.
The Pentagon invested over a billion dollars in fiscal year 2024 researching directed energy weapons, or lasers, that would cost only $3 per shot and have a range of 12 miles. Those systems have yet to be used in the field.
Despite the cost imbalance, the real fear for many in the defense community is the depleted stockpile of munitions.
“What scares me is that we will run out of these things,” said Tom Karako, the director of the Missile Defense Project at the Center for Strategic and International Studies in Washington. “Not that we can’t afford them, but that we’ll run out before we can replace them.”
