A new high-temperature polymer fuel cell that operates at 80-160 degrees Celsius, with a higher-rated power density than state-of-the-art fuel cells, solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses.

New research shows that fuel poverty makes people's physical and mental health worse. Researchers found that not being able to keep homes warm enough affects people's levels of life satisfaction. But they also found that it impacts people's physical health by causing higher levels of inflammation, measured by fibrinogen, a blood-based biomarker.

Earth's global average surface temperature in 2021 tied with 2018 as the sixth warmest on record, according to independent analyses done by NASA and NOAA. Collectively, the past eight years are the warmest years since modern recordkeeping began in 1880.

A 170 m record of marine sediment cores extracted from Adélie Land in Antarctica is yielding new insights into the complicated relationship between sea ice and climate change.

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

More Antarctic meltwater is surfacing than was previously known, modifying the climate, preventing sea ice from forming and boosting marine productivity- according to new research. For the first time, researchers have been able to obtain full-depth glacial meltwater observations in winter, using instruments attached to the heads of seals living near the Pine Island Glacier, in the remote Amundsen Sea in the west of Antarctica.

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.
