How Humboldt founded climate research
How Humboldt founded climate research
Alexander von Humboldt was a pioneer of climate research. On his voyages to America (1799-1804) and Asia (1829), he conducted meteorological measurements that he used to develop a modern, holistic model of the Earth's climate.

Revisiting the past in Greenland
Revisiting the past in Greenland
SLF biologists are retracing two expeditions undertaken 20 and 90 years ago. Like their predecessors, they will be recording the plant populations they come across, and analysing how these have changed over recent decades. They expect this to provide new insights into the effects of climate change. Biologists Christian Rixen and Andreas Gygax from the WSL Institute for Snow and Avalanche Research (SLF) set off for Greenland on 25 July, following in the footsteps of two earlier scientists.

Scientists gain insight into geothermal-technology induced seismicity
Scientists gain insight into geothermal-technology induced seismicity
Scientists have developed a model that sheds light on the seismic risks arising from subsurface fluid injections carried out as part of geothermal energy extraction. To support the shift to a carbon-free economy, energy producers are eagerly looking for ways to safely extract geothermal energy from deep underground.

Future image of Weidteile - an attractive urban quarter
Following the suspension of the A5 Westast implementation project at the end of 2020, Stadtlabor Biel/Bienne is presenting a further developed vision of the future for the redesign of the Bernstrasse axis in the direction of Brügg.

Widespread illegal trade of hazardous chemicals
Widespread illegal trade of hazardous chemicals
Researchers from Switzerland and China have studied the global trade in highly hazardous chemicals subject to a global treaty - the Rotterdam Convention. The results are sobering: Nearly half of the total trade volume of these chemicals crosses national borders illegally, calling for strong international and national action.

Why there are no kangaroos in Bali (and no tigers in Australia)
Why there are no kangaroos in Bali (and no tigers in Australia)
Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role. If you travel to Bali, you won't see a cockatoo, but if you go to the neighbouring island of Lombok, you will.

Climate-neutral air travel: Is it possible?
Climate-neutral air travel: Is it possible?
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have performed calculations to work out how air traffic could become climate-neutral by 2050. They conclude that simply replacing fossil aviation fuel with sustainable synthetic fuels will not be enough. Air traffic would also have to be reduced.

The summer solstice effect
The summer solstice effect
Spring keeps getting earlier, but the timing of leaf fall in autumn has been more of a mystery. For the first time, a study helps solve this mystery by revealing the pivotal role of the summer solstice. The research shows that warming before the solstice triggers an earlier onset of leaf senescence, while warming after the solstice slows down the discoloration process.

Global warming caused 60 percent of Swiss heat deaths in the summer of 2022
Global warming caused 60 percent of Swiss heat deaths in the summer of 2022
Climate change is intensifying heat, leading to a significant increase in heat-related health problems. About 60 percent of the more than 600 heat-related deaths in the summer of 2022 in Switzerland can be attributed to human-induced global warming. This is shown by a study led by the University of Bern.

A dazzling white ghost
A dazzling white ghost
The woodcock's habits are discreet and nocturnal. A true ghost of the forest, it is rarely seen. We now know that its tail feathers are the purest white in the bird world. Sempach. The woodcock is active at night and lives secluded in damp forests. A veritable ghost of the forest, it is usually discovered by scaring it off on a hiking trail: a brown-spotted bird the size of a pigeon.

4000 scenarios for a climate turnaround
4000 scenarios for a climate turnaround
Using an extensive computer simulation of the climate, the global economy and the global energy system, researchers at PSI have been analysing different ways of mitigating climate change, together with colleagues from the US, China, Ireland, Finland and Sweden. CO2 emissions from human activities account for about 42 billion tonnes per year.

EPFL spin-off closes the loop on PET recycling
EPFL spin-off closes the loop on PET recycling
EPFL spin-off DePoly has developed a method for recycling polyethylene terephthalate (PET) at ambient temperature, even when it's dirty or mixed with other plastics.

FireDrone supports the fire department
FireDrone supports the fire department
Researchers from Empa and Imperial College London are developing a heat-resistant drone that can analyze the source of danger at close range in the event of a building or forest fire. This allows firefighters to optimize the strategy of a high-risk operation before entering the danger zone. Where others rush out, they have to go in: Firefighters put themselves in dangerous situations during rescue operations - sometimes right in the midst of a sea of flames.

How an ocean-fertilising bacterium forms aggregates
Trichodesmium, a common and ecologically important bacterium, fertilises nutrient-poor regions of the oceans and thereby enables higher life. Crucial to its success is its ability to form aggregates in order to react quickly to changes in its environment. researchers have shown how the microbes organise themselves in this process.

Global warming accelerates CO2 emissions from soil microbes
Global warming accelerates CO2 emissions from soil microbes
When Microorganisms decompose organic material in the soil, they actively release CO2 into the atmosphere. This process is called heterotrophic respiration. A novel model shows that these emissions could surge by up to 40 percent by the end of the century - most significantly in the polar regions. In brief It is projected that by the end of the century, CO2 emissions from soil microbes will escalate.

The 2°C warming target remains in sight
The 2°C warming target remains in sight
Can the 120 countries that signed the Glasgow Climate Pact keep to the pledges they made for 2100? Researchers at EPFL have developed detailed models for calculating long-term CO2 emissions-reduction trajectories and analyzing their impact on global warming. Their findings offer a glimmer of hope. The study by EPFL's Laboratory of Environmental and Urban Economics (LEURE) has sounded a rare note of optimism amid an otherwise bleak climate outlook.

Climate Change Releases Carbon Stocks Deep Underground
Climate Change Releases Carbon Stocks Deep Underground
Subsoils are the largest storehouses for carbon, as well as one of the most important sources of carbon dioxide in the atmosphere. Global warming is accelerating the decomposition of soil humus. It is also affecting the waxy and woody compounds which help plants store carbon in their leaves and roots and were previously thought to be stable.

Climate Change: Rising Rainfall, not Temperatures, Threaten Giraffe Survival
Climate Change: Rising Rainfall, not Temperatures, Threaten Giraffe Survival
Giraffes in the East African savannahs are adapting surprisingly well to the rising temperatures caused by climate change. However, they are threatened by increasingly heavy rainfall, as researchers from the University of Zurich and Pennsylvania State University show. Climate change is expected to cause widespread declines in wildlife populations worldwide.

How much microplastics is there in Swiss rivers and lakes?
How much microplastics is there in Swiss rivers and lakes?
Plastic particles less than five millimeters in size, also known as microplastics, often settle far away from their point of origin. researchers have now developed a model that can be used to calculate the concentration of microplastics in Swiss lakes and rivers. Every year, 14,000 tons of plastic end up in Swiss soils and waters, in part in the form of microplastics: Particles in the micro to millimeter range.
