Restoring nature equitably

Efforts to restore degraded ecosystems have so far fallen short of meeting global targets. Sound restoration must better incorporate social processes promoting equity in order to effectively benefit people, climate and biodiversity, says Sara Löfqvist.

Researching, learning and adapting

One of the greatest unknowns in climate change is the question of how particulate matter affects clouds. Yu Wang is using machine learning and satellite data to investigate the surprising role of these tiny particles in the atmosphere.

Alien plant species are spreading rapidly in mountainous areas

Until now, mountain regions have been largely spared from biological invasions. But a new monitoring study shows that alien plants are spreading rapidly to higher altitudes along transport routes worldwide.

A snow-free Switzerland?

There has been a great deal of media focus on the near-total lack of snow in Swiss ski resorts at the beginning of the year. Sonia Seneviratne explains why we will have to get used to this scenario and what needs to be done about it.

Immediate uptick in investment needed to reach net zero

A new study by ETH Zurich researchers reveals that if Europe fails to immediately invest 302 billion euros in climate-relevant infrastructure, it will not reach its target of net-zero greenhouse gas emissions by 2050.

Climate action: Methane is our most powerful lever

While the insufficient measures increasingly argue against reaching the 1.5-degree target, we could still achieve it with a rapid reduction in methane emissions, writes Cyril Brunner.
