In 2024, global temperatures exceeded 1.5°C for the first time, signaling that the world is on track to pass this limit within the next decade. In a new commentary, IIASA experts and collaborators argue that this new reality requires a rethink of accountability in climate policy.
Climate worry is associated with depressive and anxiety symptoms among Finns of all ages. However, these symptoms are less common among individuals whose climate-related hope is combined with various forms of action, such as volunteering, following a plant‑based diet or avoiding air travel. Hope that society is capable of mitigating climate change is also associated with fewer depressive and anxiety symptoms.
Cities occupy just a small fraction of Earth's land, but they act as the planet's massive carbon engines, pumping out the lion's share of global CO2 emissions. To stop climate change, we first have to measure it accurately—street by street and chimney by chimney. A comprehensive new review published in Carbon Research takes a deep dive into the sophisticated networks designed to "sniff out" these emissions, highlighting both the technological triumphs and the massive gaps still remaining in our global monitoring net.
A new peer-reviewed study evaluating climate policies in 40 countries over a 32-year period finds that carbon pricing and taxation—combined with investments in renewable energy and research—are among the most effective tools governments can use to reduce CO₂ emissions.
The fight against climate change relies heavily on finding better ways to capture carbon dioxide before it escapes into our atmosphere. While carbon nanotubes have long been seen as a "wonder material" for this task, their internal structures are often locked away like a closed pipe. Now, a research team from the Skolkovo Institute of Science and Technology (Skoltech) has pioneered a deceptively simple way to pop those caps open and supercharge their adsorption capacity.
Climate change is not only disrupting supply chains and asset values, it is also quietly reshaping companies’ choice of business partners.
