"Together, wind and solar generated 22% of global electricity in April, compared with 20% from gas." More evidence: low cost wins in power generation. Gas is expensive and getting more expensive.

Glaciologists and officials in canton Valais are closely tracking the Oigschtchummun Glacier above the hamlet of Fafleralp in the Lötschental, just a few kilometres from the Birch Glacier and the devastated village.

One more year: Ice loss at Konkordiaplatz on Aletsch #Glacier is just... wow 😲 Minus 4.6 metres of ice. Will there ever be a call: "Make Aletsch Great Again"? It would be about time

Like pulling the plug of a bathtub: an incredible mass of #glacier ice disappearing at Griesgletscher (🇨🇭/🇮🇹) in one century. It felt emotional to visit the exact same spot @swisstopo cartographers chose in 1919. The view was so different. Simply unbelievable!! @vaw-glaciology.bsky.social

Why Switzerland remains heavily dependent on fossil fuels despite its climate goals?

“The 2026 findings point to a psychological turning point for Switzerland,” according to Marcus Burke, a Swiss-based analyst at Ipsos.

Switzerland is among the ten countries warming the fastest in the world. @scnat.ch @soniaseneviratne.bsky.social

“Santa Marta represents a historic breakthrough: it is the first time we bring together a group of nations willing to act,” said Tzeporah Berman, founder and chair of the Fossil Fuel Non‑Proliferation Treaty Initiative. @tzeporah.bsky.social @fossiltreaty.bsky.social

As the Middle East conflict pushes up fuel costs, households across Europe are turning to solar panels, heat pumps and electric cars. In Switzerland, residents face hurdles on the path to renewable energy.

“Unfortunately, when discussing data centre sustainability, nobody considers the IT component,” says Matthias Haymoz of the Swiss Datacenter Efficiency Association (SDEA). “This is a problem because today 80% of a data centre’s energy goes into IT.”

"The conflict in the Middle East serves as a stark, tragic validation of why the Santa Marta Conference is urgent", says Alex Rafalowicz of the Fossil Fuel Treaty Initiative. @alexraf.bsky.social @fossiltreaty.bsky.social

"Fossil fuels are not delivering energy security — they are undermining it", says Paola Yanguas Parra, a policy advisor at the International Institute for Sustainable Development. @iisd.org @paoyanguas.bsky.social

The global rise in oil prices due to the conflict in the Middle East has made the import of fossil fuels more expensive. For Switzerland, the additional energy costs could amount to nearly CHF5 billion ($6.3 billion) per year, according to a researcher at @ethz.ch. @brunncy.bsky.social

“While we hear and see a lot from the people who are really for climate action or the people who are really against it, in fact, these are just two visible groups that may actually be in the minority,” says Keith Smith, a senior researcher at @ethz.ch.

After the Swiss parliament cut funding for a Basel to Malmö night train, Swissinfo journalist Kristian Brandt tried a similar route with his daughter. What followed was a day-long journey that shows the pluses, minuses and new opportunities for this alternative to flying.

Oil-market players in Switzerland: “Our supply of oil products is always guaranteed; there is no fear of shortages".

Even as Switzerland phases out its ageing reactors, the debate on building new ones has been revived.

Researchers from the @unibe.ch are delving into Antarctica’s oldest ice, extracted from a depth of more than 2,500 metres. Join researchers Hubertus Fischer and Florian Kraus as they unveil their groundbreaking work.

When we installed solar panels, it felt like an easy way to help the climate. A year later, that early optimism has stayed with me. But I did not expect that my decision would turn from a climate choice into an exercise in using spreadsheets.

Sudden, spectacular and often deadly: avalanches are among the main natural hazards in the Alps and other mountainous regions. However, their impact is not always purely destructive. They play a crucial role in the survival of many glaciers in Switzerland and worldwide. @wslresearch.bsky.social

Global warming is casting a long shadow over the future of the Winter Games. Could Switzerland’s proposed low-impact 2038 edition be a path forward?

Although the digital world may feel intangible and efficient, it’s a substantial contributor to environmental pollution and depleting the planet’s resources. @greenpeace.eu

Despite years of awareness campaigns and a national project to reduce waste, large amounts of edible food go directly from Swiss kitchens to the trash.

The catastrophic collapse of the Birch Glacier that wiped out the Swiss mountain village of Blatten in May has triggered an unprecedented scientific effort to understand how a mountainside could break up so violently – and what might come next.

The #WSL #CCAMM research programme ends after eight years: researchers reveal how #climatechange is altering #naturalhazards in the Alps – and where action is now required. More details in the news article: www.slf.ch/en/news/ccam...

More people are turning to courts to push states and companies to do more for the climate. What’s been the result? We asked one of the world’s leading experts in environmental law and climate litigation. @sabincenter.bsky.social

Glaciers of the world - local melting and global impacts

Zurich is home to a unique housing cooperative meant to model sustainable living. A decade on, some residents have found changing their habits to be more challenging than expected.

Against the backdrop of COP30 – the first United Nations climate conference held in the Amazon – Indigenous communities whose rainforest preservation efforts are key to climate solutions are facing new, violent threats as a UN carbon scheme struggles to take hold.

Four residents of the small Indonesian island of Pulau Pari have vowed to fight one of the most climate-damaging industries: cement. @greenpeace.eu

CAT Global Update 2025 🚨 Ten years after the #ParisAgreement we see little to no measurable progress in warming projections - for the fourth consecutive year. The 2035 #NDCs have made no difference to our warming outlook. 🔗 bit.ly/CAT_Global_2...

"Developed countries should not use Article 6 (of Paris Agreement) to meet their climate targets. They bear significant historical responsibility for emissions and must prioritise domestic action", says Federica Dossi of @carbonmarketwatch.bsky.social. @fridaysforfuture.bsky.social

“Today we are fully capable of giving up fossil fuels, both for heating buildings and for transportation,” says Martine Rebetez, professor of applied climatology at the University of Neuchâtel and the @wslresearch.bsky.social. @ethz.ch

“Discouragement and sadness prevail when I consider what has been done politically,” says Sonia Seneviratne, climatologist at @ethz.ch. @soniaseneviratne.bsky.social @retoknutti.bsky.social

The goal of limiting global warming to 1.5°C above pre-industrial levels will not be achieved. We outline the possible consequences of crossing this threshold for life on Earth and in Switzerland, a country already heavily affected by rising temperatures. @wmo-global.bsky.social

Ten years after the Paris Agreement, a survey of climate scientists in Switzerland shows they no longer expect the world to limit warming to 1.5°C. On average, they expect warming of 2.5°C by 2100. @ethz.ch @unibe.ch @unil.bsky.social

“The decade following the Paris Agreement in 2015 saw an unprecedented acceleration in wind and solar generation growth like no other electricity technology has seen before,” Kostantsa Rangelova, an analyst at @ember-energy.org.

The glaciers of the Pamirs in Central Asia were among the few in the world that remained stable – or even grew – as others melted. According to a study, this anomaly may have come to an end. @vaw-glaciology.bsky.social

Farmers around the world are adapting to rising temperatures. In Switzerland they are experimenting with new crops that can withstand heat and drought. @sustainablefarming.bsky.social @fao.org

[2/2] This year’s melt was driven by a snow-poor winter and summer heatwaves. Glaciers below 3k m lost over 2 m of ice. Shrinking glaciers also destabilize mountains, as seen in May, when a rock–ice avalanche buried Blatten in the Lötschental. 🔗 to #GLAMOS report: doi.glamos.ch/pubs/annualr...

[1/2] 📢 GLAMOS @scnat.ch press release out today: Swiss glaciers lost another 3% of their volume in 2025, the 4th-largest decline ever measured. In just 10 years, they’ve lost a quarter of their ice mass. Over 1k small glaciers have already vanished. 🔗 to press release: scnat.ch/en/uuid/i/9d...

“This year turned out to be a little less extreme than we feared", says Matthias Huss, director of GLAMOS. “However, what worries me is that we’re getting used to these very negative years. It’s a new normal, but one that shouldn’t be there.” @matthias-huss.bsky.social @vaw-glaciology.bsky.social

Holcim holds the first line of defence for all companies worldwide whose business harm the climate.

In Switzerland, it’s worth taking extra care when moving house or clearing out a flat: it’s not uncommon to find a Vreneli hidden away in a drawer, a bag or even in the lining of an old coat.

The worst disaster in Swiss history, in which 88 people perished after two million cubic metres of ice and debris plunged onto a dam construction site, was dismissed as an “unforeseeable event”. Sixty years after the Mattmark tragedy, the survivors’ memories persist.

Twenty years after the “flood of the century”, the Swiss approach to hazard insurance, based on solidarity, could inspire other countries dealing with increasingly frequent disasters.
