Comfort with a smaller carbon footprint      (via sciencedaily.com)     Original source 

Researchers have developed a data-driven AI algorithm for controlling the heating and cooling of an office building. The system does not require ambient sensors or specific knowledge of the building's rooms. During heating operations, the system was able to achieve energy savings of up to 30%, which can represent significant reductions to cost and environmental impact.

Two-dimensional compounds can capture carbon from the air      (via sciencedaily.com)     Original source 

Some of the thinnest materials known to humankind -- MXene and MBene compounds -- may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb carbon dioxide molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.

Study identifies jet-stream pattern that locks in extreme winter cold, wet spells      (via sciencedaily.com)     Original source 

Winter is coming—eventually. And while the earth is warming, a new study suggests that the atmosphere is being pushed around in ways that cause long bouts of extreme winter cold or wet in some regions. The study’s authors say they have identified giant meanders in the global jet stream that bring polar air southward, locking in frigid or wet conditions concurrently over much of North America and Europe, often for weeks at a time. Such weather waves, they say, have doubled in frequency since the 1960s. In just the last few years, they have killed hundreds of people and paralyzed energy and transport systems.

Controlled burns help prevent wildfires; Climate change is limiting their use      (via sciencedaily.com)     Original source 

Climate change means the American West will have 17% fewer safe days to light prescribed fires for wildfire management, according to new research. Winter, however, will see a net 4% increase in the number of favorable days. Implementing controlled burns in the West will require changes to policy and the availability of firefighters.

Study on mysterious Amazon porcupine can help its protection      (via sciencedaily.com)     Original source 

A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.

Climate and human land use both play roles in Pacific island wildfires past and present      (via sciencedaily.com)     Original source 

It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.

Whales Around the World Play With Kelp Clumps      (via sciencedaily.com)     Original source 

A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.

Riddle of varying warm water inflow in the Arctic now solved      (via sciencedaily.com)     Original source 

In the 'weather kitchen,' the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time. Experts finally have an explanation for why: Due to unusual atmospheric pressure conditions over the North Atlantic, low-pressure areas are diverted from their usual track, which disrupts the coupling between the Azores High, the Icelandic Low and the winds off the Norwegian coast. This finding is an important step toward refining climate models and more accurately predicting the fate of Arctic sea ice in the face of progressing climate change.
