Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.

The findings indicate that stronger declines in sea ice will occur when an atmospheric feature known as the Arctic dipole reverses itself in its recurring cycle. The many environmental responses to the Arctic dipole are described in a recent article. This analysis helps explain how North Atlantic water influences Arctic Ocean climate. Scientists call it Atlantification.

Since marine zooplankton respond to the available light, this is also changing their behavior -- especially how the tiny organisms rise and fall within the water column. As an international team of researchers has now shown, in the future this could lead to more frequent food shortages for the zooplankton, and to negative effects for larger species including seals and whales.

In 2018, researchers found two roundworms (nematode) species in the Siberian Permafrost. Radiocarbon dating indicated that the nematode individuals have remained in cryptobiosis since the late Pleistocene, about 46,000 years ago. Researchers have now used genome sequencing, assembly, and phylogenetic analysis and found that the permafrost nematode belongs to a previously undescribed species, Panagrolaimus kolymaensis.

Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.

This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea surface. Clumps of dead algae also transport the plastic with its pollutants particularly quickly into the deep sea -- and can thus explain the high microplastic concentrations in the sediment there.

The investigators report that many of the woolly mammoth's trademark features -- including their woolly coats and large fat deposits -- were already genetically encoded in the earliest woolly mammoths, but these and other traits became more defined over the species' 700,000+ year existence. They also identified a gene with several mutations that may have been responsible for the woolly mammoth's miniscule ears.

But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data and climate models, that while the 'Warm Arctic-Cold Continent' pattern will continue as the climate continues to warm, Arctic warming will become a less reliable predictor of extreme winter weather in the future.

When the ground thaws and becomes unstable in response to climate change, it can lead to the collapse of industrial infrastructure, and in turn to the increased release of pollutants. Moreover, contaminations already present will be able to more easily spread throughout ecosystems. According to new findings, there are at least 13,000 to 20,000 contaminated sites in the Arctic that could pose a serious risk in the future.

They linked airborne repeat lidar data to time-series Landsat products (satellite images) to delineate thaw settlement patterns across six large fires that have occurred since 2000. The six fires resulted in a loss of nearly 99,000 acres of evergreen forest from 2000 to 2014 among nearly 155,000 acres of fire-influenced forests with varying degrees of burn severity. This novel approach helped to explain about 65 percent of the variance in lidar-detected elevation change.

A study of Glacier National Park hiking trails during and after a COVID-19 closure adds evidence to the theory that humans can create a 'landscape of fear' like other apex predators, changing how species use an area simply with their presence. Researchers found that when human hikers were present, 16 out of 22 mammal species, including predators and prey alike, changed where and when they accessed areas. Some completely abandoned places they previously used, others used them less frequently, and some shifted to more nocturnal activities to avoid humans. 星期四,2023年1月19日09:31:30 EST //www.koonmotors.com/releases/2023/01/230119093130.htm //www.koonmotors.com/releases/2023/01/230118111656.htm A temperature reconstruction from ice cores of the past 1,000 years reveals that today's warming in central-north Greenland is surprisingly pronounced.

Humans have been continually interested in discovering how to better move across wet or frozen surfaces safely -- whether to improve shoes for walking on sidewalks or tires to maneuver the roadways. But what makes it possible for some Arctic animals to walk and run across the ice so effortlessly and gracefully without slipping and falling? Researchers took a deep dive into the paws of polar bears to find out. What the team discovered was that all bears (except sun bears) have papillae on their paw pads, but that the papillae on polar bears were taller -- up to 1.5 times. And, that the taller papillae of polar bears help to increase traction on snow relative to shorter ones. Even though polar bears have smaller paw pads compared to the other species (likely because of greater fur coverage for heat conservation), the taller papillae of polar bears compensate for their smaller paw pads, giving them a 30-50% increase in frictional shear stress.

Sea ice greatly modifies the exchanges of heat, momentum and mass between the atmosphere and the ocean. So, the timings of the sea ice melt and freeze onsets, as well as the length of the melt and freeze seasons, play a key role in the 'heat budget' of the atmosphere-ice-ocean system.

A new analysis shows that while forecasts accurately predicted the massive storm, models seriously underestimated its effect on sea ice. Results suggest where forecast models for a changing Arctic Ocean could improve.

In this region alone, a previously unknown transport route uses the biological carbon pump and ocean currents to absorb atmospheric CO2 on the scale of Iceland's total annual emissions, as researchers report.

These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers have now shown that different plant communities in the tundra play a key role in this energy exchange but are not taken into account in climate models.
