This is shown in a new Uppsala University research study now published in the scientific journal Proceedings of the Royal Society B. (2021-02-02)

Increasing snow depth prevented wintertime soils from cooling during the warming hiatus
Scientists investigated snow cover along with other direct and indirect soil temperature influences in northeastern China. The research further showed that the increasing snow depth in northeastern China may be the main reason for the continued warming trend in soil temperatures. In addition to the thermal insulation effect of snow cover, the ability for soil to record human changes and environmental influences, or ''soil memory'' is also important, especially at greater depths.

Marine heatwaves becoming more intense, more frequent
When thick, the surface layer of the ocean acts as a buffer to extreme marine heating--but a new study from the University of Colorado Boulder shows this ''mixed layer'' is becoming shallower each year. The thinner it becomes, the easier it is to warm. The new work could explain recent extreme marine heatwaves, and point at a future of more frequent and destructive ocean warming events as global temperatures continue to climb. (2021-01-28)

Copper-indium oxide: A faster and cooler way to reduce our carbon footprint
Emergent e-fuel technologies often employ the reverse water-gas shift (RWGS) reaction to convert atmospheric CO2 to CO. While efficient, this reaction requires high temperatures and complex gas separation for high performance. However, for the first time in the world, scientists from Japan have now demonstrated record-high CO2 conversion rates at relatively low temperatures in a modified chemical-looping version of RWGS using a novel copper-indium oxide. (2021-01-13)

Northern lakes at risk of losing ice cover permanently, impacting drinking water
Close to 5,700 lakes in the Northern Hemisphere may permanently lose ice cover this century, 179 of them in the next decade, at current greenhouse gas emissions, despite a possible polar vortex this year, researchers at York University have found. Those lakes include large bays in some of the deepest of the Great Lakes, such as Lake Superior and Lake Michigan, which could permanently become ice free by 2055. (2021-01-13)

Research shows rising lizard temperatures may change predator-prey relationship with snakes
Researchers from the University of Hong Kong and Toho University have discovered that predation by snakes is pushing lizards to be active at warmer body temperatures on islands where snakes are present, in comparison to islands free from snakes. The findings show that lizard thermal biology is highly dependent on predation pressures and that body temperatures are rising suggest that such ectothermic predator-prey relationships may be changing under climatic warming. (2021-01-07)

Christmas trees can be green because of a photosynthetic short-cut
How can conifers that are used for example as Christmas trees keep their green needles over the boreal winter when most trees shed their leaves? Science has not provided a good answer to this question but now an international team of scientists, including researchers from Umeå University, has deciphered that a short-cut in the photosynthetic machinery allows the needles of pine trees to stay green. The study was published in the journal Nature Communications. (2020-12-23)

SwRI-led team finds meteoric evidence for a previously unknown asteroid
A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago. The composition of a piece of the meteorite Almahata Sitta (AhS) indicates that its parent body was an asteroid roughly the size of Ceres, the largest object in the main asteroid belt, and formed in the presence of water under intermediate temperatures and pressures. (2020-12-21)

Compressive fluctuations heat ions in space plasma
New simulations carried out in part on the ATERUI II supercomputer in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from compressive turbulent fluctuations in the plasma. These finding have important implications for understanding observations of various astronomical objects such as the images of the accretion disk and shadow of the M87 supermassive black hole. (2020-12-18)
