When firefighters arrived at a blaze in a pine forest on the Greek island of Rhodes last July, flames were already leaping above the trees into the night sky. The volunteers needed to act fast, but dense vegetation on the forest floor blocked access.

With crews unable to get close, the fire spread and within days had engulfed the Mediterranean island, forcing 19,000 people to flee - one of the biggest disaster evacuations in Greece's history.

"Have you ever tried walking through a forest that has not been cleared for more than 10 years? It's so difficult," said firefighter Nikos Karpathakis, who was at the scene.

As another summer approaches, and as climate change makes wildfires ever more deadly across southern Europe, Greece has developed a new doctrine to contain the damage, including deploying an extra fire truck to each new blaze, speeding up air support and clearing forests.

But five firefighters and three experts said the initiative doesn't address shortfalls in planning and prevention and more devastation awaits.

"We are clinging to a doctrine which insists on fire suppression instead of adopting an integrated fire management strategy," said Theodore Giannaros, a fire meteorologist at the National Observatory of Athens.

Heat waves triggered wildfires across swathes of Portugal, France, Spain and Italy last year and caused dozens of deaths.

The situation is especially dire in Greece, which has just recorded its warmest winter on record, creating ideal conditions for fires that threaten crops, homes and the booming tourism industry.

Last August, a fire in the northern Evros region destroyed an area larger than New York City and killed at least 20 people - the deadliest European blaze of 2023. Fires this year have begun earlier than expected, including one in March in a mountainous area normally blanketed by snow.

"It will be a very tough wildfire season. Climate change is here," Vassilis Kikilias, Minister for Climate Crisis and Civil Protection, told Reuters.

MORE NEEDED

Greece has made strides to combat fires, including building firebreaks around power poles in forested areas and stepping up training.

Some 700 additional forest rangers were hired this year. Crews have cleared 12,000 hectares of forest since 2022 and another 7,000 hectares will be completed by the end of May, the environment ministry said.

"For the first time in 50 years, we're stepping into forests and building firebreak zones," Kikilias said. "Certainly, it won't be done at once throughout Greece but it's a good start."

Under a 2.1 billion euro ($2.25 billion) plan, Greece has concluded tenders for more than 1,000 fire engines and seven DHC-515 aircraft, and plans to install sensors to detect smoke.

Experts worry it won't be enough.

The cleared forests make up only a tiny fraction of the nearly 7.5 million hectares of Greek woodland. Some of the tendered trucks and aircraft will not be delivered for years.

They said more money should be spent creating a corps of wildfire specialists who can draft risk maps and analyze how fires are likely to spread. They recommended embracing firefighting methods used in other parts of the world, such as "backfiring", where firefighters light new fires in the path of existing ones to starve them of fuel.

Volunteer firefighter Karpathakis is haunted by last summer. He said crews laid down 2 km of hoses to get closer to the Rhodes fire. It was too late. Gale force winds blew the blaze beyond their reach.

"I worked non-stop for so many days but the situation didn't get any better."

Scientists have detected the "fingerprints" of a black hole's event horizon -- the boundary from which nothing can escape -- for the first time, according to research published on Wednesday.

The discovery was made by studying ripples in space-time called gravitational waves that were created when two black holes violently smashed into each other.

A black hole's event horizon is known as the "point of no return" because not even light can avoid being swallowed into its darkness.

This has made them incredibly difficult to learn anything about.

However, there is one event of such cataclysmic violence that it could offer a chance to glimpse this extreme phenomenon -- when two black holes merge into one.

When this cosmic death spiral occurs, it shoots gravitational waves across the universe which scientists have been detecting for the last decade.

For the new research published in Nature, an international team of researchers analyzed data from the strongest gravitational wave ever recorded, known as GW250114, detected by the LIGO observatory in January 2025.

By isolating the last burst of waves -- known as "direct waves" -- from this black hole merger, the scientists said they were able to extract information from closer to an event horizon than ever before.

"This black hole horizon concept normally appears in science fiction," lead study author Sizheng Ma of the Perimeter Institute for Theoretical Physics in Canada told AFP.

"But now we are really able to touch the region around the horizon with gravitational data," he added.

"Sometimes I cannot believe this is really happening."

- Causing a stir -

The last stage of two black holes merging is like a spoon stirring a glass of water, Sizheng Ma explained.

The resulting swirl in space creates the ripple of gravitational waves that travel at the speed of light in all directions.

If the metaphorical spoon is stirring close enough to the black hole's event horizon, "this offers us a chance to decode the physics around that region", Sizheng Ma said.

By supporting the theory of general relativity, the results "proved that Einstein was correct again," he added.

The scientists emphasized that more research was needed to decipher what can be gleaned about event horizons using this method.

But they did detect information about how black holes twist space around themselves as they rotate -- a phenomenon known as "frame dragging".

"This is similar to pushing a glass into a table and twisting it, so that the tablecloth winds up around it," Maximiliano Isi, a gravitational wave astrophysicist at Columbia University, told AFP.

In the future, the team of scientists hope to find signs of tiny changes known as quantum fluctuation.

"In this way, we can really probe this near horizon region to look for a new physics," including searching for a deviation from general relativity, Sizheng Ma said.

- Reaction mixed -

Experts not involved in the study urged caution.

Francesco Sannino, an Italian theoretical physicist who studies black holes, told AFP it was "compelling analysis" but needed to be checked by other researchers.

Still, it was "striking" that the scientists were able to show that gravitational waves carried the event horizon's "fingerprints," he said.

The astrophysicist Isi described the work as "tantalizing".

"More generally, understanding the physics of black holes and their mergers is important as it might shed light on how space and time are woven together at a more fundamental level," he told AFP.

Sean McWilliams, an astrophysicist at West Virginia University, was skeptical that the gravitational wave frequency analyzed by the scientists was actually "dictated" by the event horizon.

For this reason, "the actual observed signal doesn't really tell us anything about the horizon or the other properties directly related to it", he told AFP.

Sizheng Ma said McWilliams's statement was "not correct," suggesting he had conflated two different aspects in the paper.

"There is often considerable resistance and criticism in the early stages of promoting a new concept," he said, adding he is working on another paper to "clarify these confusions and possible misinterpretations".

A large asteroid that will zoom harmlessly past Earth on Saturday will be visible to stargazers using a small telescope or large binoculars, the European Space Agency announced Wednesday.

The asteroid will come within 2,560,000 kilometers of Earth at 1114 GMT on Saturday, which is more than six times the distance between the Earth and the Moon.

Called (152637) 1997 NC1, the asteroid will be speeding along at nearly nine kilometers a second, posing no threat to Earth as any chance of an impact has been ruled out.

Discovered in 1997, the asteroid is estimated to be between 750 and 1,650 meters wide, according to calculations based on how much sunlight it reflects.

However other estimates suggest it could be smaller, AFP quoted the ESA as saying in a statement.

"A close approach to Earth by an object this size only occurs every few years, although this time the bright nearby Moon might impede its observability at closest approach," Juan Luis Cano of the ESA's Planetary Defense Office said in a statement.

For stargazers with telescopes or binoculars, the asteroid will be visible in parts of the Northern Hemisphere as it approaches, almost everywhere as it speeds past Earth, and only from the Southern Hemisphere as it departs.

But this depends if people are in areas of the world where the sky is dark enough as it passes.

Singapore, Indonesia, Malaysia and Brunei face a high risk of severe haze this year due to hot and dry weather conditions, biofuel demand and economic pressures, a research institute said Wednesday.

The Singapore Institute of International Affairs said it was the second time it had issued a red risk rating since launching its Haze Outlook report in 2019. The previous red risk rating was in ⁠2023, Reuters reported.

Here are some ⁠details:

August to September is the peak danger period for haze in the Southeast Asian region, driven by the El Niño and Indian Ocean Dipole weather phenomena, the report said.

The ⁠return of El Niño is expected to create a longer and stronger dry season at a time when fire preparedness could be adversely affected by economic uncertainty and cost pressures.

The SIIA said rising costs of fertilizer and fuel as a result of the Iran war could lead to unsustainable activity such as the use ⁠of ⁠fire rather than machinery to clear land and dispose of waste.

Land use could also intensify as demand for biofuels rises due to energy supply disruptions.

"This trend will continue even if the US-Iran agreement holds, as countries now want energy independence," said SIIA associate director Khor Yu-Leng.

ASEAN cooperation and sustainable land management will be critical to reducing risks, the report said.
