Research published in Regional Environmental Change has shown that as climate zones shift toward hotter and drier conditions, ecological diversity will decline, posing a major threat to terrestrial ecosystems with far-reaching social and ecological impacts. The research team analyzed Kenya’s geographic distribution and arrangement of climate zones between 1980-2020. Over that time, tropical climate regions ...

‘Tis the season for flooding and road washouts. Not only can they create inconvenient, time-consuming detours and safety risks, but they’re also expensive to repair. And as climate change brings more extreme weather, including heavier rains, the cost of adapting infrastructure is expected to go up, along with the cost of repairing damage. But a ...

Small ponds emit a surprisingly large amount of methane compared with larger water bodies. Because ponds are so tiny, they have been difficult to track, and their contributions to terrestrial greenhouse gas emissions are largely unaccounted for. In a new study, Mullen et al. used deep learning to construct a fine-grained map of ponds in ...

Norwegian and Estonian researchers have developed a method to map hidden meltwater paths in glaciers. Having a better understanding of how water moves inside and under the glaciers helps to better predict the motion, melting rates, and possible sudden collapses of glaciers. The small floating drifters, about the shape, size, and weight of an average ...

Auf dem Geoportal des Bundes ist eine neue Karte aufrufbar. Die Karte stellt für jedes Schweizer Wohngebäude dar, wie viel CO2 unter Normbedingungen ausgestossen wird. Dies teilt das Bundesamt für Umwelt (Bafu) mit. Mit einem interaktiven CO2-Rechner kann demnach zudem simuliert werden, wie sich ein Heizungswechsel und energetische Sanierungen auf den CO2-Ausstoss auswirken. Die Karte ...

While the push to mandate EVs aims to reduce tailpipe emissions such as carbon dioxide — the federal government has set a target of complete EV adoption by 2035 — swapping every vehicle on the road still won’t eliminate all the sources of air pollution that can impact human health. That’s because brake pads, rotors ...

The researchers, from the University of Cambridge, developed the algorithm, which gives an accurate measurement of tree diameter, an important measurement used by scientists to monitor forest health and levels of carbon sequestration. “When you’re trying to figure out how much carbon a forest is sequestering, these ground-based measurements are hugely valuable, but also time-consuming,” ...

At the feet of mountain glaciers, melting ice forms pools of water that can be trapped behind moraines. And with warming temperatures, these pools are surging in both size and number. In Alaska and northwestern Canada, 183 new lakes appeared between 1984 and 2019, covering 483 square kilometers (190 square miles). New research showed that ...

A first count of trees in Africa’s drylands has enabled scientists to calculate how much carbon they store and could help devise better conservation strategies for the region and beyond, a study said Wednesday. The number of trees in the vast region—the count came to nearly 10 billion—has not been known up to now, and ...

Researchers from Florida Atlantic University, in collaboration with the United States Army Corps of Engineers Cold Regions Research & Engineering Laboratory, and Alaska Ecoscience, systematically analyzed the effects of six large fires that have occurred since 2000 on the Tanana Flats lowland in interior Alaska on land cover change, vegetation dynamics, and terrain subsidence, or ...

Above the islands of Hawaii on January 28, a green laser was seen piercing the night sky, silently tracing a path towards the horizon like a stutter in the Matrix’s code.
