Europe’s historic temperature shift, from summer to winter in just one day

Europe’s historic temperature shift, from summer to winter in just one day

fighting frost france april 2023

Europe has experienced one of the most rapid temperature flips on record in April 2024 — moving from numerous record-breaking summer-like temperatures at the beginning of the month to record-breaking late April records and frost. Climatologist Maximiliano Herrera said Europe has never seen a month like that extreme.

Temperatures across Europe during the first two weeks of April were marked by numerous record-high temperatures, with summer-like temperatures bringing the feeling of upcoming summer and promoting early blooming in many plants. However, this was followed by an abrupt weather reversal in mid-April, bringing unusually cold temperatures, freezing rain, and snow.

“Europe, the crib of meteorology, is experiencing its most extreme month ever seen,” said weather historian and climatologist Maximiliano Herrera.

Slovenia has become a notable example of this sharp climatic shift. On April 16, following more than ten days of summer-like weather with highs exceeding 30 °C (86 °F), the country reported a drastic change. Temperatures fell to icy levels accompanied by wind, rain, and snow, causing not only agricultural concerns but also traffic disruptions and minor damage from weather conditions.

As we reported on April 21, the most significant temperature drop was recorded in Podčetrtek, a town in eastern Slovenia, where temperatures fell from 27.2°C (81.0 °F) on the afternoon of April 15 to just 1 °C (33.8 °F) by 15:00 LT the following day, marking a record decline of 26.2 °C (47.2 °F).

A similar rapid temperature shift was recorded across central Europe, severely affecting the region’s agriculture, particularly fruit trees and vineyards now vulnerable after early blooming.

Winemakers in France and other affected regions fought frost with anti-frost candles, evoking a familiar scene that we’ve seen repeating over the past several years. This sequence marks yet another year where early-season warmth promoted plant blooming, only to be followed by a destructive frost.

Protect the Arctic Region: Already Threatened Arctic Ecology Can be Devastated Further by Rapid Militarization

The Arctic region is warming at twice the global rate, leading to rapid melting of ice–some have even predicted ice-free summers by year 2034. This has brought unprecedented threats to various species of the region including the polar bear. Some species are threatened by the shrinking, even vanishing habitats where they have always lived safely and happily, some are threatened by the fast reducing access to their staple food, while some are threatened by weather extremes.

Despite this there is still relentless march to exploit the vast natural resources of the region, including oil, natural gas, rare earth and other minerals. Partly due to the huge natural resources and partly due to strategic and geo-political reasons, big power confrontation in this remote region can also increase.

In fact melting of ice increases the possibility of higher exploitation of natural resources as well as carving out of new maritime routes with all its strategic and commercial implications. Another complication is the increasing confrontational situation of NATO and Russia which may get extended, tragically, even to the Arctic region with very heavy costs to ecology and to native people.

The Arctic region is spread over 8 countries, 7 of which are NATO members. These are USA, Canada, Iceland, Denmark (Greenland), Norway, Sweden and Finland. The eighth country is Russia.

While Russia has a well-established military presence here, this is largely defensive as Russia has important strategic interests to protect here spread over a vast area. With Finland and Sweden recently becoming NATO members and with the situation in Ukraine not working out to be favorable to NATO plans, the USA may just be tempted to try to create difficulties for Russia in this region…

0.04%: Small Does Not = Immaterial

0.04%: Small Does Not = Immaterial

Think CO2 Concentration at 0.04% is Low? These 10 Toxins are Deadly at Far Lower Concentrations.

If you follow me on Twitter , you’re probably familiar with the onslaught of nonsense from the anti-science crowd.

I’m fine with respectful, reasoned responses, but many of the arguments are insulting, childish or conspiratorial.

I know, if I were trying to win these people over I shouldn’t belittle them. But I’m not trying to win them over. There’s plenty of objective data showing why they’re wrong, but they choose to believe their feelings and political loudmouths instead of science. Nothing I do will change their minds. So I continue to make my observations about the world – take it or leave it.

Frankly, I don’t understand how these people have the time to scour Twitter for posts outside their world view. This brigade of deniers with nothing better to do has clearly gone through the same training program. They make the same points and share the same charts. Often, their ‘rebuttal’ has nothing to do with the original tweet. It’s like they’re blindly copy-pasting from their “how to be a science-denier” guidebook.

I usually ignore (or block) these comments, but once in a while something drives me nuts.

One argument I’ve heard on repeat recently is that CO2 is only 0.04% of the atmosphere, therefore it cannot affect the climate.

I’m being kind when I say this is a simplistic argument.

Small does not = immaterial.

To prove my point, here are 10 things that are deadly at levels far below 0.04% concentration:

  1. Botulinum toxin: It can be lethal at about 1 nanogram per kilogram of body weight. This equates to incredibly minute concentrations, roughly 0.0000000001% in the body.
  2. Ricin: A dose of about 22 micrograms per kilogram of body weight can be lethal. This is also a very low concentration, about 0.0000022%.

Accepting Our Lack of Agency

Accepting Our Lack of Agency

An early morning picture at Black Rock Mountain State Park in Georgia

The last month has been focused on acceptance, and has been building up to the inexorable, immutable, and irrevocable truth that besets us within the confines of the set of predicaments we face. The one thing I constantly see and hear is about all the things that “we” can do to mitigate the situation –  all the ways we can “regenerate” nature – and all the ways we can “save the planet.” While I do think that society is beginning to realize that something is wrong, most people are still following the constant narratives being delivered in an attempt to keep the public calm. George Tsakraklides says it best right here, quote:

The toxic positivity theatre isn’t confined to the corporatocracy. Hope, whether real and justified or morbidly delusional, is an irresistible narcotic for humans.

A hopeful message will always win over bitter truths, and our information machine knows this: news media habitually turn even the most sobering news into fast-consumable entertainment, making a mockery of reality.

It used to be that this was the role of movies: to allow us to experience a funny or terrifying world and entertain ourselves either way, knowing that it is all fake and we are watching from the safety of our sofa. But now the same is done to real, actual news coming from around the world: reality has been gamified, turned into amusement, into a video game in the most morally corrupt, sick, and irresponsible way possible. All of this, in the name of “hope” and “bringing lightness” to our collapse predicament.

‘We were in disbelief’: Antarctica is behaving in a way we’ve never seen before. Can it recover?

‘We were in disbelief’: Antarctica is behaving in a way we’ve never seen before. Can it recover?

Deception Island, Antarctica.

Look out over Antarctica in the summer, and time seems frozen. The South Pole’s midnight sun appears to hover in place, never dropping below the horizon for weeks between November and January.

But the Antarctic’s timelessness is an illusion. Only a decade ago, on summer nights across the coast, the sun would glide ever so slightly over the ocean, dusting its ice floes in golden light.

Yet today, much of this sea ice is nowhere in sight. And scientists are increasingly alarmed that it may never come back.

Antarctica feels very distant, but the sea ice there matters so much to all of us,” Ella Gilbert, a polar climate scientist at the British Antarctic Survey, told Live Science. “It’s a really vital part of our climate system.”

Until recently, Antarctic sea ice fluctuated between relatively stable summer minimums and winter maximums. But after a record minimum in 2016, things began to shift. Two record lows soon followed, including the smallest minimum ever in February 2023 at just 737,000 square miles (1.91 million square kilometers).

As winter began in March of that year, scientists hoped the ice cover would rebound. But what happened instead astonished them: Antarctic ice experienced six months of record lows. At winter’s peak in July, the continent was missing a chunk of ice bigger than Western Europe.

South Koreans sue government over climate change, saying policy violates human rights

Plaintiffs, lawyers and activists gather outside South Korea’s constitutional court in Seoul ahead of a public hearing for a climate lawsuit on Tuesday, April 23, 2024.

SEOUL — As plaintiffs, lawyers and activists chanted slogans outside South Korea’s constitutional court on Tuesday, 17-month-old Woodpecker giggled, sending ripples of laughter through the crowd.

Woodpecker is the nickname of Choi Heewoo, the youngest among more than 250 plaintiffs involved in Woodpecker et. al. v. South Korea, one of four petitions filed since 2020 that the court is considering together in a landmark case.

The plaintiffs argue that by not effectively tackling climate change, their government is violating its citizens’ human rights.

While there are other cases in progress elsewhere, this is the first in Asia to have a public hearing and plaintiffs say that the court’s verdict, when it comes, is also likely to be the first in Asia.

Woodpecker’s mom and legal representative Lee Donghyun made him a plaintiff while he was still in her womb. She says South Korea’s government is deferring the task of reducing carbon emissions to future administrations and younger generations.

“The more we think this task can be delayed now, the bigger the burden our future generations will have,” she says. “I think it’s the same as passing on a debt to your children.”

Environmentalists criticize carbon emission reduction goals

Plaintiffs argue that South Korea’s goal of reducing carbon emissions by 40% by 2030 compared to 2018 levels is insufficient — it will lead to disastrous climate change and violate their constitutional rights.

South Korea’s human rights watchdog has filed an opinion with the government, stating that climate change is a human rights issue, and that the government is therefore obligated to protect citizens from it.

Should we tweak the atmosphere to counteract global warming?

Should we tweak the atmosphere to counteract global warming?

With severe climate impacts becoming more and more apparent, many scientists think we should explore ways to block out solar radiation, but doing so would be risky.

Earlier this month, on the deck of a second world war aircraft carrier docked in San Francisco, a giant fan began spraying sea salt particles into the air.

Few people, beyond those on the ship and bystanders on the nearby dock, would have taken much notice of the resulting plume of salt spray drifting upwards.

But this fan, and the spray it pumps out, has global significance. It marks one of the first real-world trials of a climate intervention known as marine cloud brightening – essentially an attempt to cool the planet by making clouds more reflective, so that they bounce more of the sun’s energy back into space.

Our chances of limiting global warming to 1.5°C above pre-industrial levels are rapidly slipping away, with a recent analysis suggesting the world will burn through the remaining carbon budget for this temperature goal by 2029 or earlier.

Meanwhile, global temperatures rose to record levels in 2023. And that extreme heat has brought extreme impacts, with widespread coral reef bleaching, severe marine heatwaves and rapid glacier loss just some of the consequences. Time is running out, scientists agree, to avert disaster.

Could geoengineering buy us time to get our house in order?

Solar radiation modification (SRM) is a type of geoengineering that involves modifying the atmosphere to tweak how much of the sun’s radiation makes it to Earth. Essentially, it would involve pumping tiny reflective particles into the atmosphere to bounce more solar radiation back into space.

Pandemics in Roman Empire correlate with sudden climate changes

Plankton living in the Mediterranean Sea some 2000 years ago have helped researchers to uncover a correlation between climate change and the spread of disease in ancient Roman Italy and into the early Middle Ages.

Using a sediment core recovered from the Gulf of Taranto, in the arch of Italy’s boot, Karin Zonneveld of the University of Bremen in Germany and colleagues reconstructed the regional climate from 200 BCE to 600 CE. The sediment record reveals that periods of rapid cooling and drying in the heart of the Roman Empire align with documented major disease outbreaks, the researchers report in a new study.

The core’s plankton fossils are from dinoflagellate cysts, also known as dinocysts. Dinoflagellates bloom in late summer and early fall, with thousands of species that thrive under varying surface temperatures and nutrient levels. By comparing the ratios of dinocyst species that flourish in warmer waters with those that flourish in cooler waters, researchers can precisely estimate historical temperatures. Dinocysts also respond to the water’s changing nutrient levels, which are controlled by precipitation. Rain and snowfall over the Italian Peninsula are channeled by rivers into the Adriatic Sea, where currents carry the nutrient-enhanced water southward around Italy’s heel and into the gulf.

The core was recovered from a location with a rather high deposition rate, with 1 cm of sediment deposited roughly every 10 years (compared with about 1 cm/1000 yr in the open Mediterranean Sea)…

Europe is the fastest-warming continent, at nearly twice the average rate, report says

Europe is the fastest-warming continent, at nearly twice the average rate, report says

The latest 5-year averages show that temperatures in Europe are running 2.3 degrees Celsius above pre-industrial levels, compared to 1.3 degrees higher globally.

Europe is the fastest-warming continent and its temperatures are rising at roughly twice the global average, two top climate monitoring organizations reported Monday, warning of the consequences for human health, glacier melt and economic activity.

The U.N.’s World Meteorological Organization and the European Union’s climate agency, Copernicus, said in a joint report that the continent has the opportunity to develop targeted strategies to speed up the transition to renewable resources like wind, solar and hydroelectric power in response to the effects of climate change.

The continent generated 43% of its electricity from renewable resources last year, up from 36% the year before, the agencies say in their European State of the Climate report for last year. More energy in Europe was generated from renewables than from fossil fuels for the second year running.

The latest five-year averages show that temperatures in Europe are now running 2.3 degrees Celsius (4.1 degrees Fahrenheit) above pre-industrial levels, compared to 1.3 degrees Celsius higher globally, the report says — just shy of the targets under the 2015 Paris climate accord to limit global warming to 1.5 degrees Celsius.

“Europe saw yet another year of increasing temperatures and intensifying climate extremes — including heat stress with record temperatures, wildfires, heat waves, glacier ice loss and lack of snowfall,” said Elisabeth Hamdouch, the deputy head of unit for Copernicus at the EU’s executive commission.

Cities are often 10-15 °C hotter than their rural surroundings

A recent global study conducted by the Joint Research Centre looks at the difference between surface temperatures of urban areas and their neighbouring rural areas in summer.

Worldwide, more than half of the people live in cities, and the share of city dwellers is projected to grow further. Cities often suffer from ‘heat islands’, the phenomenon of temperatures being higher within cities than in neighbouring rural zones. This amplifies the effect of heatwaves in cities and increases the risk to human health.

Scientists at the European Commission’s Joint Research Centre examined the difference between land surface temperatures in urban areas with a population over 50,000 people and in their rural surroundings in summer between 2003 and 2020.

Working with satellite data, scientists measured that surface temperatures in cities were sometimes up to 10-15°C higher than in their rural surroundings. The study also estimated that the temperature in extreme heat islands in cities around the world has risen on average by 1°C in since 2003.

The global scale of the study and high-resolution of the spatial analysis make it possible to compare cities in different climate zones and even different parts within megacities.

Hotspots and cooler areas within global megacities

Across global megacities, such as Tokyo, New York, Paris and London, the study observed a very high intra-city variability in temperature. Hotspots are often found in industrial areas, where waste heat, the use of dark construction material and absence of vegetation can result in very high land surface temperatures. For example, in Paris hotspots are found east of Saint-Denis and near Chevilly Larue, around large industrial complexes.

The study highlights that slums can also form hotspots of heat due to their chaotic, dense and unregulated urbanisation. Intense heat exposure, combined with poverty, poor housing conditions and reduced access to cooling options poses serious health threats to people.

Plastics industry heats world 4 times as much as air travel, report finds

Pollution from the plastics industry is a major force behind the heating of the planet, according to a new report from the federal government.

The industry releases about four times as many planet-warming chemicals as the airline industry, according to the paper from scientists at the Lawrence Berkeley National Laboratory.

Its emissions are equivalent to those of about 600 coal plants — about three times the number that exist across the U.S.

And if plastic production remains constant, by 2050 it could burn through nearly a fifth of the Earth’s remaining carbon budget — the amount of carbon dioxide climate scientists believe can be burned without tipping the climate into unsafe territory.

The report from the national lab comes out as civil society and public health groups, plastics industry representatives and members of national governments prepare to travel to Ottawa, Canada, for the fourth meeting of the International Negotiating Committee, which seeks to create a legally binding treaty to reduce plastics pollution.

Those negotiations are likely to be split by stark divisions. Representatives of environmental groups and countries across the Global South have called for limits on production of plastics, while the plastics industry insists that plastic pollution can be eliminated by stricter rules around recycling.

In last fall’s negotiations in Kenya, public health and environmental campaigners focused on the dangers posed by plastics — including microplastics and nanoplastics — in the human body and environment.

But these negotiations left out a key part of the plastics problem, the Lawrence Berkeley researchers note: the role of plastic in climate change.

Understanding climate warming impacts on carbon release from the tundra

The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into carbon sources, exacerbating the effects of climate change.

A team of more than 70 scientists from different countries used so-called open-top chambers (OTCs) to experimentally simulate the effects of warming on 28 tundra sites around the world. OTCs basically serve as mini-greenhouses, blocking wind and trapping heat to create local warming.

The warming experiments led to a 1.4 degrees Celsius increase in air temperature and a 0.4 degrees increase in , along with a 1.6 percent drop in . These changes boosted ecosystem  by 30 percent during the growing season, causing more carbon to be released because of increased metabolic activity in soil and plants. The changes persisted for at least 25 years after the start of the experimental warming—which earlier studies hadn’t revealed.

“We knew from earlier studies that we were likely to find an increase in respiration with warming, but we found a remarkable increase—nearly four times greater than previously estimated, though it varied with time and location,” says Sybryn Maes of Umeå University, the study’s lead author.

The increase in ecosystem respiration also varied with local soil conditions, such as nitrogen and pH levels. This means that differences in soil conditions and other factors lead to geographic differences in the response—some regions will see more carbon release than others. Understanding the links between soil conditions and respiration in response to warming is important for creating better climate models.

The vast ravines swallowing whole neighbourhoods around the world

This was once a bustling street in Buriticupu, a city in north-east Brazil.

Now it is a vast chasm 80m deep – a 20-storey building could fit inside it.

Canyons like this are known locally as “voçoroca” or “torn land” in the indigenous Tupi-Guarani language.

The phenomenon is a result of gully erosion, one of the most aggressive forms of soil degradation caused by rain and waste water.

And it is advancing at a worrying speed, destroying thousands of homes in Latin America and Africa.

Former police officer José Ribamar Silveira was nearly killed when he fell into this gully.

He got lost as he was driving home from a party one night in May 2023.

As he turned the car around, the 79-year-old reversed and accelerated backwards. It was dark, there were no warning signs or barriers around the voçoroca, and before he knew it, the car – with him inside – plunged into the vast hole.

“When the car slid, even though it was falling quickly, I thought of my youngest son,” he tells the BBC.

Baby Gael had turned four months old the day before. “I asked God to protect me so that I could raise my little son,” says Lt Silveira.

He was knocked unconscious and woke up at the bottom of the ravine three hours later. After a complicated rescue operation and months of convalescence, he can now walk without crutches.

His experience is a vivid example of the risks facing Buriticupu’s 70,000 residents.

As more gullies appear, there are fears that the city in Maranhão state, on the edge of the Amazon rainforest, could be split in two. At 350m above sea level, Buriticupu has about 30 gullies, with the largest two separated by less than 1km.

“If the authorities don’t contain this, they will meet and form a river,” says Edilea Dutra Pereira, a geologist and professor at the Federal University of Maranhão.

Gullies have been part of the Earth’s geological history for millions of years.

Don’t Talk To Me About Solutions

Don’t Talk To Me About Solutions

The System Itself is the Problem

It’s 2024 and I’m suspicious of “solutions”. Solutions to what, exactly? The excess greenhouse gases in the atmosphere that have already seen us breach the 1.5 degree limit set by the Paris Agreement? The ocean acidification that’s bleaching corals en masse? The rampant deforestation and habitat destruction that’s seen half of the world’s wilderness turned into farmland? How about the economic system with its limited prescription of value that converts what is priceless into profit? The political gridlock on climate thanks to our addiction to fossil fuels? The record-breaking profits of those energy companies with plans to double global extraction? Or the debt bondage that keeps the global south trapped in poverty? The political hierarchy that means the world’s most war-mongering country calls the shots? How about resource scarcity for an energy transition? How about water shortages? Genocide?

There’s no magic bullet for this level of complexity. What is clear—more and more as the months go on and climate goals, peace goals and equity goals are sacrificed in the name of imperialism—we need systems revolution, not systems reform. The world is looking at food shortages, droughts, a financial crisis, world war three and worsening impacts of the climate and biodiversity crisis, not to mention the likelihood of an authoritarian elected to the most powerful position in the world. This is an unprecedented eco-crisis. We need to change how we organise. And we need to organise.

I like “eco”: it comes from the Ancient Greek “οἶκος”, (pronounced eek-os) meaning household, which is the root of ecosystem, ecology, ecophilosophy etc etc. We consider “eco” to signify the environment, but what it reveals is that the environment is our home; the wide-scale wilderness of the planet itself is our home; our household, if we can step up to the role of stewards…

As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study by Earth scientists at the University of Hawai’i (UH) at Mānoa has compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.

The research is published in the journal Annual Review of Marine Science.

“While it has been recognized that shallowing  will eventually result in chronic flooding as it surfaces, what’s less known is that it can start causing problems decades beforehand as groundwater interacts with buried infrastructure,” said Shellie Habel, lead author and coastal geologist in the School of Ocean and Earth Science and Technology (SOEST) at UH Mānoa. “This  often results in coastal groundwater changes being fully overlooked in infrastructure planning.”

The research team aimed to create awareness about these issues and offer guidance from world experts on managing them. Habel and co-authors reviewed existing literature to examine the diverse effects on different types of infrastructure. Additionally, by employing worldwide elevation data and geospatial data that indicate the extent of urban development, they identified 1,546 low-lying coastal cities and towns globally, where around 1.42 billion people live, that are likely experiencing these impacts.
