The First-Ever European Climate Risk Assessment Reveals A Continent Unprepared For Rising Extremes In 2024
According to the European Environment Agency’s first-ever risk assessment for the EU, released on Monday, Europe is facing escalating climate dangers and is unprepared for them.
According to the agency, Europe is becoming more vulnerable to more frequent and severe weather extremes, such as wildfires, drought, odd rainfall patterns, and flooding, and it must address them urgently to defend its energy, food security, water, and health.
These climate hazards “are growing faster than our societal preparedness,” according to the EEA’s executive director, Leena Ylä-Mononen.
The First-Ever European Climate Risk Assessment Reveals A Continent Unprepared For Rising Extremes.
The survey identified 36 significant climate hazards for the continent, including challenges to ecosystems, economics, health, and food systems, and discovered that more than half want stronger action now. It identified eight issues that require immediate attention, including ecosystem conservation, heat protection, flood and wildfire mitigation, and disaster assistance funding.
According to the analysis, Europe is the world’s fastest-warming continent, with temperatures rising twice as quickly as in other regions since 1980. The heat has been related to more powerful rains and floods, and the analysis anticipates lower rainfall and more severe droughts in southern Europe.
It warns that many of the climate dangers outlined will become catastrophic unless fast and decisive action is taken. It suggests that the EU and its member states work with regional and local governments to decrease climate risks and increase adaptation to warming.
Manon Dufour, Brussels director for climate think tank E3G, described the research as “a huge wake-up call” for the continent, with consequences for climate policy at the European and national levels.
At the European level, Dufour stated that the research might “open the eyes” of European leaders who are now preoccupied with security concerns, as weather change can impact economic and energy security.
On a national level, Dufour stated that the report should encourage finance ministers, in particular, “to make economic and social resilience the key priority.” She cited the report’s prediction that economic damages from heat waves and floods might total 1 trillion euros ($1.1 trillion) year by the end of the century.
“It’s clearly in our best interests to adapt to changing risks we can no longer avoid, including preparedness for larger extremes and surprises, and to keep the risks from spiraling out of control by reducing greenhouse gases,” said Maarten van Aalst, director-general of the Royal Netherlands Meteorological Institute.

Sven Harmeling, head of climate at Climate Action Network Europe, stated that Europe “can do more, even by 2030,” to reduce emissions from coal, oil, and gas combustion and increase investments in climate adaptation, particularly by preserving ecosystems such as wetlands and forests that can absorb carbon and act as natural extreme weather barriers.
He emphasized that any attempts to mitigate the effects of warming “must deliver this in a way that provides social and economic benefits for all.”
Silvia Pastorelli, a Greenpeace EU climate campaigner, agreed, adding that the bloc’s resilience measures, such as adapting homes to aid with heating in the winter and cooling in the summer, should prioritize the most vulnerable communities. “Fairness in the weather response is essential,” Pastorelli stated.
According to the report, the European Union and its member states have achieved “considerable progress” in recognizing and planning for weather hazards.
Europe, for example, “has done well in relation to coastal flooding,” according to Julie Berckmans, an EEA climate risk expert. She stated that there had been no catastrophic storm floods on the continent in 60 years, and some progress has been achieved in mitigating the health risks of heat and significant river floods.

However, greater action is required in these areas “because the risks are increasing rapidly,” she stated. Berckmans cited heat stress as an example of a serious issue for people. She suggested that countries and cities enhance spatial planning to better prepare for future heat-related health risks.
On Tuesday, the European Commission will unveil its action plan in response to the report.
EU Commission spokesperson Tim McPhie stated that the EEA’s study has “given a very clear warning and a very clear call to action of what’s to come.”

As summer approaches in Australia, residents are warned to look out for the funnel web spider, one of the country’s deadliest species.
In addition to advising the public to avoid funnel-web spiders during mating season, the Australian Reptile Park in New South Wales has even asked people to capture live funnel-web spiders so they can “milk” their venom.
Native to eastern Australia, the funnel web spider can kill humans in as little as fifteen minutes if they do not receive medical treatment for its poisonous bite.
There have been thirteen fatalities attributable to this species, but none since the development of antivenom in 1981. The Australian Reptile Park is appealing to the public for assistance capturing and donating spiders, as the serum relies on milking live spiders.
Hunting for the funnel net spider in residential areas is common practice after a particularly wet and warm season. Look for spiders in cool, dark places like pools, garden residue, heaps of dirty clothing, and outside shoes.
Australian Reptile Park spider keeper Emma Teni recently blogged about how they rely on spider donations more than ever, especially now that breeding season has arrived and the temperature is perfect.
“Male funnel-web spiders have short lifespans, and with approximately 150 spiders required to make just one vial of antivenom, we need the public’s help to ensure we have enough venom to meet demand.”
“If you spot an egg sac while collecting a spider, it’s important to safely collect that as well,” said Teni. “It can provide a robust supply of healthy young spiders to aid in our antivenom production.”
The spiders won’t be able to climb plastic or glass, but Teni suggests capturing funnel webs in a wide-mouthed jar with a cover. Then, you can lead the spiders into the container using a long spoon or something similar.
After that, fill the jar with moist soil, screw on the top, and bring it to the designated drop-off spot.
“We depend on the public for spider donations, and we want to make sure everyone stays safe during the collection process, especially with conditions being so favourable this year,” said Teni.

A Spacecraft Is On Its Way To A Harmless Asteroid Slammed By NASA In A Previous Save-The-Earth Test
CAPE CANAVERAL, Florida – A spacecraft launched Monday to probe the site of a cosmic accident.
The European Space Agency’s Hera spacecraft launched on a two-year trip to the little, harmless asteroid slammed by NASA two years ago as a practice run for the day when a murderous space rock threatens Earth. It’s the second phase of a planetary defense experiment that could one day save the globe.
SpaceX’s Falcon rocket vanished with Hera into the late morning clouds. An hour later, cheering erupted in the control center in Germany as the spacecraft split from the rocket’s upper stage and returned home. “It’s an amazing day,” the space agency’s director general, Josef Aschbacher, said later.
The 2022 crash of NASA’s Dart spacecraft reduced Dimorphos’ orbit around its larger companion, indicating that if a harmful rock was heading our way, it might be pushed off course with adequate warning.

Scientists are eager to analyze the aftermath of the impact up close to determine how effective Dart was and what improvements may be required to protect Earth in the future.
“The more detail we can glean the better as it may be important for planning a future deflection mission should one be needed,” University of Maryland astronomer Derek Richardson stated before launch.
Researchers want to know if Dart (short for Double Asteroid Redirection Test) created a crater or changed the 500-foot (150-meter) asteroid more dramatically. It seemed to be a flying saucer before Dart’s blow and may now resemble a kidney bean, according to Richardson, who participated in the Dart mission and is assisting Hera.
Dart’s wallop sent rubble and boulders hurtling off Dimorphos, adding to the impact’s momentum. For months, the debris track extended thousands of miles (almost 10,000 kilometers) into space.
According to flight director Ignacio Tanco, some rocks and debris may still be hovering about the asteroid, posing a threat to Hera.

“We don’t really know very well the environment in which we are going to operate,” Tanco informed me. “But that’s the whole point of the mission is to go there and find out.”
European authorities refer to the $400 million (363 million euros) effort as a “crash scene investigation.”
“Hera is going back to the crime scene and getting all the scientific and technical information,” said project manager Ian Carnelli.
Carrying a dozen science instruments, the compact car-sized Hera must swing past Mars in 2025 for a gravitational boost before landing at Dimorphos by the end of 2026. It’s a moonlet of Didymos, the Greek word for twin, a five-times larger asteroid that spins quickly. At that point, the asteroids will be 120 million miles (195 million kilometers) from Earth.
Hera will attempt to enter orbit around the rocky duo, progressively reducing flyby distances from 18 miles (30 kilometers) to a half-mile (1 kilometer). The spacecraft will examine the moonlet for at least six months to determine its mass, shape, composition, and orbit around Didymos.
Before the crash, Dimorphos circled its larger partner from three-quarters of a mile (1,189 meters) away. Scientists believe the orbit has become tighter and more oval-shaped, and that the moonlet may be tumbling.
Two shoebox-sized Cubesats will launch from Hera for even closer drone-like examinations, with one employing radar to peek beneath the moonlet’s boulder-strewn surface. Scientists believe Dimorphos was produced from particles shed by Didymos. The radar measurements should assist in determining whether Didymos is the small moon’s parent.

After their survey, the CubeSats will attempt to land on the moonlet. If the moonlet tumbles, the situation will become more complicated. Hera may potentially conclude its mission with a perilous touchdown but on the bigger Didymos.
Asteroids, which are remnants of the solar system’s origin 4.6 billion years ago, circle the sun principally between Mars and Jupiter in what is known as the main asteroid belt, where millions of them live. When they fall from the belt and land in our area, they become near-Earth objects.
NASA now has around 36,000 near-Earth objects, the majority of which are asteroids, although there are also some comets. More than 2,400 of them are deemed potentially dangerous to the Earth.

NEW YORK — Prepare to spot a rare and dazzling comet.
The space rock is hurling toward Earth from the far reaches of the solar system and will make its closest approach on Saturday. It should be visible through the end of October, assuming clear skies.
A Rare Comet Brightens The Night Skies In October
Comet Tsuchinshan-Atlas should be visible to the naked eye, but binoculars and telescopes will provide a clearer view.
“It’ll be this fuzzy circle with a long tail stretching away from it,” explained Sally Brummel, planetarium manager at the Bell Museum in Minnesota.
What is a comet?
They are frozen remains from billions of years ago when the solar system was formed. They heat up as they swing toward the sun, revealing their distinctive streaming tails.
In 2023, a green one that had last visited Earth 50,000 years ago flew past again. Other significant flybys were Neowise in 2020 and Hale-Bopp and Hyakutake in the mid to late 1990s.
Where did Tsuchinshan-Atlas come from?
Also known as C/2023 A3, was found last year and named after the observatories in China and South Africa that spotted it.
It originated in the Oort Cloud, which extends far beyond Pluto. After making its closest approach to Earth at 44 million miles (71 million kilometers), it will not return for another 80,000 years, provided it survives the journey.
A Rare Comet Brightens The Night Skies In October
Every year, several comets are detected, but many of them burn up near the sun or are too far away to be observed without special equipment, according to Larry Denneau, a key researcher with the Atlas telescope that helped discover it.
How to View
Those seeking to see Tsuchinshan-Atlas should go outside about an hour after sunset on a clear night and look to the west.
The comet should be visible from both the Northern and Southern Hemispheres.
