Researchers from Lawrence Berkeley National Laboratory and Fathom Bristol used a hydraulic model to consider the degree to which human-caused climate change may have affected flooding in Houston in 2017 during Hurricane Harvey. Resources at the National Energy Research Scientific Computing Center were used to quantify the increase in Houston flood area and depth and to host a portal where other scientists and the public can access and explore the resulting data.
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC) launch a peer-reviewed report based on a 4-day virtual workshop on addressing the biodiversity and climate crises together involving 50 jointly-selected international experts.
Paleoclimatologist Niels de Winter and colleagues developed an innovative way to use the clumped isotope method to reconstruct climate in the geological past on the seasonal scale. They show that dinosaurs had to deal with hotter summers than previously thought. The results suggest that in the mid latitudes, seasonal temperatures will likely rise along with climate warming, while seasonal difference is maintained. This results in very high summer temperatures.
When nature vanishes, people of color and low-income Americans disproportionally lose critical environmental and health benefits--including air quality, crop productivity and disease control--a new study in Nature Communications finds. The research is the first national study to explore the unequal impacts on American society--by race and income--of projected declines in nature and its benefits. Researchers find multiple natural benefits will drop for people of color by an average of 224%-111% between 2020-2100, as white communities see gains.
Every five years, the UNESCO Science Report provides an update of trends in science governance. Written by 70 authors from 52 countries, it aggregates data on spending, personnel, scientific publications and patents. The latest edition tracks progress towards the UN's 2030 Sustainable Development Goals and the rapid progress of the Fourth Industrial Revolution. It also tracks the impact of the COVID-19 pandemic on global research and innovation.
Some four months ago, a devastating flood ravaged the Chamoli district in the Indian Himalayas, killing over 200 people. The flood was caused by a massive landslide, which also involved a glacier. Researchers at the University of Zurich, the WSL and ETH Zurich have now analyzed the causes, scope and impact of the disaster as part of an international collaboration.
The study represents the first systematic attempt to investigate whether a climate future with net-zero carbon emissions is not only possible but also plausible. They conclude that the efforts need to be far more ambitious. The results imply that global surface warming of less than 1.7° Celsius by 2100 is not plausible, but nor is a rise of more than 4.9 degrees.
Using more than 3.4 million citizen scientist observations of 140 different bird species across the continental U.S., researchers found that common bird species avoided areas with excessive noise. In areas where light and noise pollution both occurred, many additional species avoided backyard feeders. Seasonal patterns and variation in the length of night also influenced how species respond to light pollution.
Researchers have created a plant-based, sustainable, scalable material that could replace single-use plastics in many consumer products.
New research led by scientists from the Max Planck Institute for the Science of Human History shows that disruptions to Indigenous land management following Iberian colonization did not always result in widespread forest regrowth in the Americas and Asia-Pacific, as has been recently argued.
