Climate change made 2022's UK wildfires 6 times more likely

Climate change made 2022's UK wildfires 6 times more likely

Euronews15-03-2025

Global sea levels rose faster than expected in 2024 as the world experienced its hottest year on record, a new study has found.
This was due to an unusual amount of ocean warming combined with meltwater from land-based ice such as glaciers, according to the NASA-led analysis.
'Every year is a little bit different, but what's clear is that the ocean continues to rise, and the rate of rise is getting faster and faster,' said Josh Willis, a sea level researcher at NASA's Jet Propulsion Laboratory in Southern California.
Since the satellite recording of ocean height began in 1993, the rate of annual sea level rise has more than doubled. In total, the global sea level has gone up by 10 centimetres since 1993.
This long-term record is made possible by an uninterrupted series of ocean-observing satellites starting with TOPEX/Poseidon in 1992.
According to the NASA-led study of the information sourced via the Sentinel-6 Michael Freilich satellite, 2024 saw a rate of sea level rise at 0.59 centimetres per year, compared to the expected rate of 0.43 centimetres per year.
The upcoming Sentinel-6B satellite will continue to measure sea surface height down to a few centimetres for about 90 per cent of the world's oceans.
In recent years, about two-thirds of sea level rise was from the addition of water from land into the ocean by melting ice sheets and glaciers. About a third came from thermal expansion of seawater.
But in 2024, those contributions flipped, with two-thirds of sea level rise coming from thermal expansion.
'With 2024 as the warmest year on record, Earth's expanding oceans are following suit, reaching their highest levels in three decades,' said Nadya Vinogradova Shiffer, head of physical oceanography programs at NASA Headquarters in Washington.
There are several ways in which heat makes its way into the ocean, resulting in the thermal expansion of water.
Normally, seawater arranges itself into layers determined by water temperature and density.
Warmer water is lighter and floats on top of cooler water, which is denser. In most places, heat from the surface moves very slowly through these layers down into the deep ocean.
But extremely windy areas of the ocean can agitate the layers enough to result in vertical mixing.
Very large currents, like those found in the Southern Ocean, can tilt ocean layers, allowing surface waters to slip down deep more easily.
The massive movement of water during El Niño - in which a large pool of warm water normally located in the western Pacific Ocean sloshes over to the central and eastern Pacific - can also result in the vertical movement of heat within the ocean.
The UN has warned that rising sea levels are endangering vast numbers of people living on islands or along coastlines.
Particularly vulnerable areas include low-lying coastal communities in India, Bangladesh, China and the Netherlands, as well as island nations in the Pacific and Indian Oceans.
In 2022, the UK experienced an unprecedented heatwave, with temperatures reaching 40C for the first time in recorded history.
This extreme heat was accompanied by widespread fires across London and elsewhere in England, which destroyed houses and prompted evacuations.
A new study has assessed the contribution of human-induced climate change to the fire and weather conditions over this period.
The analysis, conducted by the Met Office, the UK Centre for Ecology & Hydrology and the University of Exeter, reveals at least a 6-fold increase in the probability of very high fire weather due to human influence.
'As we experience more hotter and drier summers as temperatures continue to rise, the frequency and severity of fires are likely to increase, posing significant risks to both natural ecosystems and human populations,' the authors write.
'This study underscores the need for further research to quantify the changing fire risk due to our changing climate and the urgent requirement for mitigation and adaptation efforts to address the growing wildfire threat in the UK.'
The study highlights how rising temperatures and drier conditions driven by climate change are dramatically increasing the risk of extreme fire weather in the UK.
England emerged as the most vulnerable UK nation in the paper, published in the journal Environmental Research Letters on Tuesday.
The researchers compared the present-day climate to one without human influence through greenhouse gas emissions to understand how climate change had impacted the chance of fire weather.
To do so, they combined data from advanced climate models and a 'fire weather index' - an indicator of hot, dry, windy weather conditions that provoke fires.
They looked at how changes in the weather affected the danger posed by fires - how far they were likely to spread and intensify - once they were ignited.
The results emphasise that climate change is not just a future concern but a present-day reality, with fire risks rising in tandem with global temperatures.
'The 2022 heatwave wasn't just record-breaking - it drastically increased the risk of fires, highlighting the growing danger climate change poses to the UK,' says lead author Dr Chantelle Burton from the Met Office.
'We found that the 2022 UK severe fires were made at least six times more likely due to human influence. With hotter, drier summers becoming the norm, fires are an emerging threat to the UK.'
One of the paper's key messages is the pressing need to adapt to rising fire risks while limiting further warming.
An urgent and significant reduction in global greenhouse gas emissions would limit the increase in future fire risks. Targeted adaptation measures could also help communities and ecosystems cope with the escalating threat.
Some actions to reduce fire risks could include enhanced land management, building away from areas at high risk, enhancing detection of fires or public campaigns to reduce accidental fires.
'The experiences of 2022 serve as a stark reminder of the urgent need to adapt to a changing climate and reduce carbon emissions to limit further warming,' says Burton.
The UK isn't the only place in Europe facing a higher risk of fire. A study published in Nature in 2024 looked at the future of fire risk for Europe as a whole.
The analysis explored the impact of a range of climate change projections on fire events compared to a baseline of fire danger using a 30-year fire weather index analysis.
The results show that areas in southern Europe could experience a tenfold increase in the probability of catastrophic fires occurring in any given year under a moderate warming scenario.
If global temperatures reach the +2C threshold, central and northern Europe will also become more susceptible to wildfires during droughts.
The increased probability of fire extremes in a warming climate, in combination with an average one-week extension of the fire season across most countries, would put extra strain on Europe's ability to cope in the forthcoming decades, the authors say.
As extreme weather events have hit the world hard in recent years, one meteorology term - atmospheric rivers - has made the leap from scientific circles to common language. Particularly in places that have been hit by them.
That stands to reason.
The heavy rain and wind events most known for dousing California and other parts of the West have been getting bigger, wetter and more frequent in the past 45 years as the world warms, according to a comprehensive study of atmospheric rivers in the current issue of the Journal of Climate.
Atmospheric rivers are long and relatively narrow bands of water vapour. They take water from the oceans and flow through the sky dumping rain in prodigious amounts.
The area they soak has increased by 6 to 9 per cent since 1980, they have increased in frequency by 2 to 6 per cent and are slightly wetter than before, the study said.
Scientists have long predicted that as climate change from the burning of coal, oil and gas makes the air warmer, it holds more moisture, which means bigger, nastier atmospheric rivers are coming in the future. This week's study shows that a more moist future is already here.
'This doesn't mean that it's necessarily all because of climate change. We didn't study that, but it does line up, broadly speaking, with some expectations of how (atmospheric rivers) will change in a warming atmosphere,' study lead author Lexi Henny, an atmospheric scientist at the University of North Carolina who did her research while at NASA.
What's happened already 'is still small relative to the changes that we think are going to happen' in a future warmer world, Henny said.
While atmospheric rivers can bring much needed rain to drought-struck places, they are often dangerous when they are strong and last long.
Just over a year ago, a series of atmospheric rivers caused hundreds of mudslides and killed several people in California. In the 1860s, California had to move its capital out of Sacramento because of an atmospheric river flooding.
These events aren't just a California thing. They actually happen all over the United States and the world, though sometimes they don't get recognised as atmospheric rivers, Henry said. An atmospheric river in New England in 2023 brought a foot of rain and 50 mph winds. A 2020 atmospheric river dumped 99 inches of snow on Alaska.
The paper not only makes sense, but is rich with new details and data that will help researchers figure out what will happen with these bouts of intense rain and snow in the future, said Christine Shields, a water scientist at the National Center for Atmospheric Research, who wasn't part of the research.

In the ever-evolving landscape of space exploration, NASA's quest to uncover the mysteries of our solar system takes a fascinating turn. While the Europa Clipper mission was initially poised to unlock the secrets of Jupiter's icy moon, Europa, the focus has now shifted to another celestial body. Enceladus, Saturn's enigmatic moon, with its potential subsurface oceans and intriguing plumes, beckons scientists with the promise of discovering extraterrestrial life. This article delves into the journey of innovation and exploration that has led us to this pivotal moment in space exploration. The Allure of Icy Moons The allure of Europa and Enceladus lies in their potential to harbor life, hidden beneath their icy surfaces. These celestial bodies offer a tantalizing possibility of subsurface oceans, where life could potentially thrive. Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have captured the imagination of scientists for decades. Their icy crusts, concealing vast oceans, make them two of the most promising candidates for the search for extraterrestrial life within our solar system. Despite the initial excitement surrounding the Europa Clipper mission, NASA faced significant challenges. Europa's intense radiation, stemming from Jupiter, posed a severe threat to the mission's success. The lander's electronics would have been vulnerable, and communication would have been limited due to Europa's unique orbit. Moreover, the harsh cold and lack of communication satellites further complicated the mission. Nonetheless, NASA's Jet Propulsion Laboratory (JPL) persevered, developing a prototype robot capable of withstanding Europa's icy terrain. This innovation laid the groundwork for future missions, albeit on a different moon. 'Tesla's Dream, Hyundai's Reality': Ten Years Later, the Electric Car King Faces a Brutal Fall From the Top Technological Innovations for Space Exploration The Europa Clipper mission, although redirected, brought forth remarkable technological advancements. The prototype lander designed for Europa was a marvel of engineering, equipped with legs for safe landings and a stereoscopic camera for navigation. One of its standout features was the 'ICEPICK' tool, capable of collecting samples from 7.87 inches deep, a crucial capability for analyzing potential biosignatures. Moreover, the lander boasted autonomous software, allowing it to make critical decisions with limited power and communication time. Rigorous field tests on Alaska's Matanuska Glacier validated the lander's capabilities, simulating the harsh conditions it would face on Europa. These innovations not only demonstrated NASA's prowess but also paved the way for exploring other icy worlds, such as Enceladus.

Trump-Musk showdown threatens US space plans

So when President Donald Trump threatened on Thursday to cancel Elon Musk's federal contracts, space watchers snapped to attention. Musk, the world's richest person, shot back that he would mothball Dragon -- the capsule NASA relies on for crew flights -- before retracting the threat a few hours later. For now, experts say mutual dependence should keep a full-blown rupture at bay, but the episode exposes just how disruptive any break could be. Founded in 2002, SpaceX leapfrogged legacy contractors to become the world's dominant launch provider. Driven by Musk's ambition to make humanity multiplanetary, it is now NASA's sole means of sending astronauts to the ISS -- a symbol of post–Cold War cooperation and a testbed for deeper space missions. Space monopoly? The company has completed 10 regular crew rotations to the orbiting lab and is contracted for four more, under a deal worth nearly $5 billion. That's just part of a broader portfolio that includes $4 billion from NASA for developing Starship, the next-generation megarocket; nearly $6 billion from the Space Force for launch services; and a reported $1.8 billion for Starshield, a classified spy satellite network. Were Dragon grounded, the United States would again be forced to rely on Russian Soyuz rockets for ISS access -- as it did between 2011 and 2020, following the Space Shuttle's retirement and before Crew Dragon entered service. "Under the current geopolitical climate, that would not be optimal," space analyst Laura Forczyk told AFP. NASA had hoped Boeing's Starliner would provide redundancy, but persistent delays -- and a failed crewed test last year -- have kept it grounded. Even Northrop Grumman's cargo missions now rely on SpaceX's Falcon 9, the workhorse of its rocket fleet. The situation also casts a shadow over NASA's Artemis program. A lunar lander variant of Starship is slated for Artemis III and IV, the next US crewed Moon missions. If Starship were sidelined, rival Blue Origin could benefit -- but the timeline would almost certainly slip, giving China, which aims to land humans by 2030, a chance to get there first, Forczyk warned. "There are very few launch vehicles as capable as Falcon 9 -- it isn't feasible to walk away as easily as President Trump might assume," she said. Still, the feud could sour Trump on space altogether, she added, complicating NASA's long-term plans. SpaceX isn't entirely dependent on the US government. Starlink subscriptions and commercial launches account for a significant share of its revenue, and the company also flies private missions. The next, with partner Axiom Space, will carry astronauts from India, Poland, and Hungary, funded by their respective governments. Private power, public risk But losing US government contracts would still be a major blow. "It's such a doomsday scenario for both parties that it's hard to envision how US space efforts would fill the gap," Clayton Swope, deputy director of the Aerospace Security Project at the Center for Strategic and International Studies, told AFP. "Both sides have every reason to bridge the disagreement and get back to business." Signs of a rift emerged last weekend, when the White House abruptly withdrew its nomination of e-payments billionaire Jared Isaacman -- a close Musk ally who has twice flown to space with SpaceX -- as NASA administrator. On a recent podcast, Isaacman said he believed he was dropped because "some people had some axes to grind, and I was a good, visible target." The broader episode could also reignite debate over Washington's reliance on commercial partners, particularly when one company holds such a dominant position. Swope noted that while the US government has long favored buying services from industry, military leaders tend to prefer owning the systems they depend on. "This is just another data point that might bolster the case for why it can be risky," he said. "I think that seed has been planted in a lot of people's minds -- that it might not be worth the trust."

'Nasa Confirms the Unthinkable': China's Giant Water Diversion Project Will Slow Earth's Rotation and Disrupt Global Timekeeping

IN A NUTSHELL 🌍 NASA confirms that human-made structures, like the Three Gorges Dam, subtly affect Earth's rotation. confirms that human-made structures, like the Three Gorges Dam, subtly affect Earth's rotation. 🏗️ The Three Gorges Dam in China is the largest hydroelectric dam, impacting both energy production and global dynamics. in China is the largest hydroelectric dam, impacting both energy production and global dynamics. 🔄 Mass movements, from natural events to infrastructure projects, can alter the planet's rotation by microseconds. ⚠️ The interplay between human activity and natural systems raises questions about unforeseen global consequences. Human-made structures have always pushed the boundaries of what's possible, affecting not just our landscapes but also, according to NASA, the very rotation of our planet. As we continue to develop massive infrastructures, we inadvertently cause minute changes in Earth's rotation. This phenomenon is compounded by climate change, which alters the distribution of the Earth's mass. The implications of these changes are not entirely understood, but they underscore the interconnectedness of our actions and the environment. Let's delve deeper into some of the most significant structures that illustrate this impact on a global scale. Ever Taller and More Massive The era of skyscrapers and colossal constructions is well upon us. Iconic structures like the Burj Khalifa, the Shanghai Tower, and The Clock Towers symbolize humanity's drive to reach new heights. However, few structures can compare to the Three Gorges Dam in China when it comes to sheer mass and impact. Situated in Hubei Province, this hydroelectric dam is the largest in the world and took nearly 18 years to complete, from 1994 to its final phase in 2012. The dam serves multiple purposes: it asserts China's newfound power, controls a dangerous river, and supports the country's energy needs. 'We'll See Gravity Like Never Before': NASA's Wild Quantum Gradiometer Will Map Earth's Invisible Forces From Orbit According to the National Center for Space Studies (CNES), the dam aims to balance territorial dynamics by emphasizing the interior over the coastal regions. This underlines a strategic goal to integrate less developed areas into the national economy. As we construct ever more massive infrastructures, we must consider their broader implications, not just their immediate benefits. 'Nuclear Breakthrough at NASA': New Space Power System Passes First Test Using Fuel That's Five Times Cheaper Than Before The Largest Hydroelectric Dam in the World China stands as the world's leading producer of hydroelectric power, both in capacity and output. Yet, despite its monumental size, the Three Gorges Dam only meets a mere 3% of China's energy demands, far less than the initially projected 10%. This discrepancy highlights the challenges of meeting national energy needs even with massive projects. However, the dam's significance extends beyond energy production; it may slow Earth's rotation. 'China Disrupts Earth's Rotation': NASA Confirms Massive Project Is Slowing the Planet With Unprecedented Global Consequences A 2005 NASA article suggests that global events involving mass movement, such as the 2004 earthquake and tsunami, can influence Earth's rotation. Dr. Benjamin Fong Chao of NASA's Goddard Space Flight Center points out that all mass movements, from seasonal weather patterns to driving a car, have an effect. This theory raises intriguing questions about the cumulative impact of our constructions and activities on a planetary scale. 0.06 Microseconds To better understand these changes, consider an analogy from IFLScience: an ice skater increases their spin by bringing their arms closer to their body. Similarly, the 2004 earthquake altered Earth's seismic structure, shortening the day by 2.68 microseconds. If the Three Gorges Dam's reservoir were filled to capacity, it would hold 10 trillion gallons of water. This mass redistribution could increase the length of a day by 0.06 microseconds, making Earth slightly more oblate. While these changes may seem negligible, they exemplify the profound influence of human activity on our planet. The potential implications for timekeeping, navigation, and even climate patterns warrant further investigation. As we continue to build and expand, understanding these subtle shifts becomes increasingly important. As humanity continues to construct monumental infrastructures, the intricate relationship between our endeavors and natural systems becomes ever more apparent. While the direct impacts of such projects are often well-studied, their broader effects, like those on Earth's rotation, remain largely speculative. What other unforeseen consequences might arise as we push the boundaries of engineering and technology? Our author used artificial intelligence to enhance this article. Did you like it? 4.4/5 (24)
