Thousands of companies around the world now regularly disclose aspects of their water use as part of corporate commitments to environmental, social, and governance goals. Yet reliable measures of corporate water withdrawals and discharges—and their impacts on local water quality and ecosystems—have been limited.... Read more

A research team at The Hong Kong University of Science and Technology (HKUST) has analyzed 40 years of data covering about 1,500 tropical cyclones and discovered that average rain rates surge by more than 20% in the 60 hours before landfall. The study is also the first to clearly identify... Read more

Particles in the atmosphere, known as aerosols, cool the climate by acting as cloud condensation nuclei. The more cloud droplets form around these particles, the less sunlight penetrates a cloud. This cools the climate, although this process is outweighed by the much stronger greenhouse effect.... Read more

A leading climate scientist has sought to set the record straight over "demonstrably incorrect" claims made in a major U.S. government report that misrepresented his work and downplayed the role of human activity in global warming.... Read more

Wildfires in the northern boreal forests of Alaska, Canada, Scandinavia, and Russia may be more damaging to the climate than previously thought, a new UC Berkeley-led study suggests. That's because these fires don't just burn through trees; they can also penetrate deep into the carbon-rich layers of soil underneath many... Read more

Efforts to advance toward a more sustainable world focus heavily on a limited set of actions and actors while overlooking key strategies and sectors needed to address the climate crisis and biodiversity loss, according to a new study published in Nature Sustainability. Conducted by the Institute of Environmental Science and... Read more

Changes in rainfall within global monsoon regions affect the livelihoods of billions. For years, climate models have suggested that the fingerprint of human-caused climate change on monsoons would become visible by a certain time. But what if that timeline is wrong? A new study published in Advances in Atmospheric Sciences... Read more

The South China Sea Throughflow (SCSTF) serves as a critical oceanic conveyor belt for heat and freshwater, mediating water exchanges between the South China Sea (SCS) and the Pacific and Indian oceans while regulating key processes such as heat and salt budgets, eddy activities, and marine biogeochemical cycles. It also... Read more

A research team led by University of Tsukuba has developed a new method to estimate long-term debris supply from steep slopes by measuring debris accumulated on decades-old abandoned roads. Debris supplied by rockfall and related slope processes is a key factor controlling the frequency and magnitude of debris flows. However,... Read more

Japan is an archipelago with diverse climate zones and complex topography that is prone to heavy rain and flooding. Add the growing effects of global warming. These disaster risks are heightened with an increased frequency and intensity of extreme precipitation events. Thus, predicting when and where these events might strike... Read more

Cities are rapidly becoming the defining residential space of human life. Over 55% of the global population lived in urban areas in 2018, a proportion projected to reach nearly 68% by 2050, according to the United Nations (UN).... Read more

From a bird's eye view, the Amazon rainforest appears as a lush green mosaic of treetops stretching as far as the eye can see. It is home to countless animal and plant species, many of which are endemic, and the forest plays an important role in the global climate as... Read more

Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially relevant for children and adolescents, whose developing bodies will experience the longest cumulative... Read more

Greenland's largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published in Climate of the Past. The study reconstructs more than 100 years of freshwater discharge... Read more

As you pass the popcorn or settle in to binge a new series, the carbon footprint of the on-screen world is unlikely to be at the front of your mind. But the reality is that, like many industries, film and television production can be startlingly resource-hungry. Part army, part circus,... Read more
