New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years.

A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.

Climate experts project a decline in the frequency of future tropical storms but an increase in their strength across the Ganges and Mekong basins allowing for better future planning.

Many of today's artificial intelligence systems loosely mimic the human brain. In a new paper, researchers suggest that another branch of biology -- ecology -- could inspire a whole new generation of AI to be more powerful, resilient, and socially responsible. The paper argues for a synergy between AI and ecology that could both strengthen AI and help to solve complex global challenges, such as disease outbreaks, loss of biodiversity, and climate change impacts.

An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.

Hadal trenches, with their deepest locations situated in the so-called hadal zone, the deepest parts of the ocean in water depth >6km, are the least-explored environment on Earth, linking the Earth's surface and its deeper interior. An international team conducting deep-subsurface sampling in a hadal trench at high spatial resolution has revealed exciting insights on the carbon cycling in the trench sediment.

As researchers around the world race against time to develop new strategies and technologies to fight climate change, a team of scientists is exploring one possible way to directly reduce the amount of carbon dioxide in the environment: Negative emissions technologies (NETs).

A hydrologist's study provides a global estimate of human destruction of natural floodplains. The study can help guide future development in a way that can restore and conserve vital floodplain habitats that are critical to wildlife, water quality and reducing flood risk for people.

Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a 'brainless' soft robot that can navigate more complex and dynamic environments.

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.

A new artificial intelligence tool can help people with Parkinson's disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care physicians with UPDRS certification.

New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.

As the Earth's human population grows, greenhouse gas emissions from the world's food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions -- reducing more greenhouse gas than food systems add.

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.

Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.

Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.

Atmospheric scientists have discovered abundant fine sea salt aerosol production from wind-blown snow in the central Arctic, increasing seasonal surface warming.

More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common. These so-called global species abundance distributions have become fully unveiled for some well-monitored species groups, such as birds. For other species groups, such as insects, however, the veil remains partially unlifted. A new study demonstrates how important biodiversity monitoring is for detecting species abundances on planet Earth and for understanding how they change.

New research by an international team of scientists explains what's behind a stalled trend in Arctic Ocean sea ice loss since 2007. The findings indicate that stronger declines in sea ice will occur when an atmospheric feature known as the Arctic dipole reverses itself in its recurring cycle. The many environmental responses to the Arctic dipole are described in a recent article. This analysis helps explain how North Atlantic water influences Arctic Ocean climate. Scientists call it Atlantification.

As global ice dams begin to weaken due to warming temperatures, a new study suggests that prior attempts to evaluate the mass of the huge floating ice shelves that line the Antarctic ice sheet may have overestimated their thickness.
