Researchers have presented a new direct air capture (DAC) method for separating CO2 from the air. Their technique uses food waste from cheese and tofu production, which is processed into protein beads. The capture and isolation of CO2 uses less energy than in conventional processes and is therefore expected to be more cost-effective.
Strong and consistent evidence shows that the entire climate system is continuing to heat, driving rapid global warming. Human activities pushed global warming to 1.37°C in 2025, and its level is projected to surpass 1.5°C in about four years. Crucially, the rate at which heat is accumulating in the Earth system suggests high levels of future warming. These are some of the key findings from the latest Indicators of Global Climate Change (IGCC) report, published today in Earth System Science Data.
An international team of more than 70 scientists, including IPCC Lead Authors, Contributing Authors, and Chapter Scientists, from 56 institutions across 17 countries contributed to this year’s IGCC study.
Human-caused sea-level rise has dramatically increased the frequency of extreme coastal flooding worldwide, making events once expected every 100 years occur about 12 times more often on average, according to a Tulane-led study published in Nature Climate Change. Using long-term tide gauge records and climate model simulations, researchers found that climate change has made these flooding events roughly four times more likely since 1900.
Storm surges and extreme water levels along coastlines occur significantly more frequently today than at the beginning of the 20th century. A new study in the journal Nature Climate Change shows that what was statistically expected to occur only once every 100 years around 1900 now occurs, in global average, about every eight years. This corresponds to an increase by a factor of about twelve. The team of authors includes Prof. Ben Marzeion from the Institute of Geography and MARUM – Center for Marine Environmental Sciences at the University of Bremen.
Climate change could make historically rare tropical cyclones more common in Southern California, significantly expanding landslide risk across the region by 2050.
