By parsing data on weather, deer populations and deer-vehicle collisions in Wisconsin, investigators show spatial synchrony could be driving population cycles, rather than the reverse.

Earth's global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.

The SUTD study will be crucial for assessing future climatic changes and making more informed water management decisions.

Scientists describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation.

Soon, ecologists thinks we'll be able to pull off the same forecasting feat for bird migrations and wildlife populations as for climate forecasts. That's because just as those recurring changes in climate have predictable consequences for humans, they also have predictable effects on plants and animals.

A new study generated improved annual maps of tropical forest cover in the Brazilian Amazon in 2000-2017 and provided better characterization on the spatio-temporal dynamics of forest area, loss and gain in this region. The Amazon basin has the largest tropical forests in the world. Rapid changes in land use, climate and other human activities have resulted in substantial deforestation in the Brazilian Amazon over the past several decades.

Researchers have revealed that atmospheric waves originating from convection over the Indian Ocean had a dramatic impact on climate conditions over South America and South Atlantic, leading to drought and marine heatwaves. Importantly, these conditions are not a one-off and are likely to happen again.

A new study documents an unprecedented number of southern marine species moving northward into California and as far north as Oregon during the 2014-2016 marine heatwave. Of 67 rare, warm-water species sightings observed, 37 had never been documented so far north before.

Climate change could have devastating effects on vulnerable residents in the Andes mountains and the Tibetan plateau, according to researchers who have been studying glaciers in those areas for decades.

A new study has uncovered the history of bleaching on a reef in the epicenter of El Nino, revealing how some corals have been able to return after facing extreme conditions.

Pioneering new research has given a new perspective on the crucial role that 'natural factors' play in global warming.

Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research.

A new study isolates key mechanisms that cause El Niño events to differ. Researchers found that the complexity and irregular occurrence of El Niño and La Niña events can be traced back to the co-existence of two coupled atmosphere-ocean oscillations, with different spatial characteristics and different frequencies.

We know heatwaves over land have been increasing, but now new research reveals globally marine heatwaves have also been increasing in length, number and intensity over the past century. More intriguing still, this trend has accelerated markedly since 1982.

A major hurricane struck the islands of Hawai'i and Maui on Aug. 9, 1871, and wrought widespread destruction from Hilo to Lahaina. A recent study revealed how historical Hawaiian-language newspapers expand knowledge of this and other natural disasters of the past.

Ocean conditions off most of the US West Coast are returning roughly to average, after an extreme marine heat wave from about 2014 to 2016 disrupted the California Current Ecosystem and shifted many species beyond their traditional range, according to a new report from NOAA Fisheries' two marine laboratories on the West Coast. Some warm waters remain off the Pacific Northwest, however.

A new study reveals that strong El Nino events can cause significant ice loss in some Antarctic ice shelves while the opposite may occur during strong La Nina events.

Researchers have addressed an international environmental problem by developing a model that can predict how certain chemicals amplify the effects of pesticides and other chemical compounds. Pesticide expert hopes that it will make environmental legislation easier.

The 2016 mass bleaching event on Western Australia's coastline is the most severe global bleaching event to ever be recorded. New research records the impact of this event to the rugged reefs of Western Australia.

On 24th October 2017, the first group of nine kulan (Asiatic wild ass) was released into an acclimatization enclosure on the edge of the Altyn Dala protected area in central Kazakhstan. The animals had been transported 1200 km by helicopter from Altyn Emel National Park in the southeast of the country. They will be released in early spring. This is the first step in a multi-year project that aims to restore the full range of large herbivores to this unique area of steppe habitat.
