Two new studies published in leading scientific journals conclude that stabilizing long-term climate risks will require sustained net-negative carbon dioxide (CO₂) emissions for centuries. Approaching the problem from distinct perspectives – legal and technological feasibility on the one hand, and economic optimization under uncertainty on the other – the research converges on a consistent message: reaching net zero is not enough.
New research from the University of Oxford published today (11 March) shows that cold snaps and heavy rain can stunt growth and reduce survival prospects in UK great tit nestlings. However, breeding earlier within a season appears to buffer against many of these weather-related effects.
As part of the Horizon Europe project Capable, researchers surveyed around 19’000 people from 13 European countries on 15 specific climate proposals in the summer of 2024. The aim was to determine how much support there is for the individual proposals and which factors influence opinions.
To this end, participants were asked specifically about the reasons behind their decisions. The analysis reveals that costs are the biggest hurdle to the acceptance of climate regulations among the population.
The innovative methodology of the study can be used in future long-term studies to better understand and track the political decisions of the population.
The tidal environment of mangrove forests serves as nurseries for many fish species. Researchers at the University of Gothenburg have measured carbon dioxide and oxygen levels in 23 of world’s mangrove areas. The study sends out a warning that these ecosystems are increasingly threatened as sea temperatures continue to rise.
