Russia's invasion of Ukraine has brought the threat of nuclear warfare to the forefront. But how would modern nuclear detonations impact the world today? A new study published today provides stark information on the global impact of nuclear war.

International solutions are needed to protect the ocean. Two sets of regulations currently under development offer an opportunity to expand protections, but a greater degree of alignment between the two must be achieved. In a new scientific article, researchers outline how this could be realized.

As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.

Nearly everyone can identify a pond, but what, exactly, distinguishes it from a lake or a wetland? A new study offers the first data-driven, functional definition of a pond and evidence of ponds' distinct ecological function, which could have broad implications for science and policy.

A white mineral ring as tall as the Statue of Liberty creeps up the steep shoreline of Lake Mead, a Colorado River reservoir just east of Las Vegas on the Nevada-Arizona border. It is the country's largest reservoir, and it's draining rapidly.

If carbon emissions are limited to slow temperature rise, up to an estimated 6,000 child deaths could be prevented in Africa each year, according to new research. New work estimated the impact of climate change on annual heat-related deaths of children under five years old in sub-Saharan Africa, from 1995 -- 2050. It shows that thousands of heat-related child deaths could be prevented if temperature increases are limited to the Paris Agreement's 1.5ºC target through to 2050. However, heat-related child deaths could double in sub-Saharan Africa by mid-century if high emissions continue.

Earth's oceans are crisscrossed with roughly 1.2 million km of fiber optic telecommunication cables. Researchers have now succeeded in using a fiber in a submarine cable as a passive listening system, enabling them to listen to and monitor whales.

The imbalance of energy on Earth is the most important metric in order to gauge the size and effects of climate change, according to a new study.

Recently, a group of 23 science and policy experts from the U.S. and Canada published a review of mining risks to watersheds ranging from Montana to British Columbia and Alaska. The paper brought together experts in salmon ecology, watershed science, mining impacts and mining policy to integrate knowledge across research fields that often work independently from one another.

A 15-year study details the origins and diversity of every known mineral on Earth, a landmark body of work that will help reconstruct the history of life on Earth, guide the search for new minerals and ore deposits, predict possible characteristics of future life, and aid the search for habitable planets and extraterrestrial life.
