May 27, 2022 Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad ...
Dec. 9, 2021 While climate change is the primary driver of permafrost degradation in Arctic Alaska, a new analysis of 70 years of data reveals that tundra fires are accelerating that decline, contributing ...
Feb. 24, 2022 New research shows rising temperatures are causing Earth's coldest forests to shift northward, raising concerns about biodiversity, an increased risk of wildfires and mounting impacts of climate ...
Nov. 1, 2021 A new study that modeled changes in the world's 45 different 'life zones' from climate change revealed that climate impacts may soon triple over these areas if the earth continues ...
Feb. 21, 2023 Scientists set out to address one of the biggest uncertainties about how carbon-rich permafrost will respond to gradual sinking of the land surface as temperatures rise. Using a high-performance ...
July 19, 2022 Scientists investigating the growth of Arctic vegetation have found that seed dispersal and fire will slow its land expansion in the long term, despite more favorable conditions from a warming ...
Aug. 16, 2023 Human-caused climate change is shortening the snow cover period in the Arctic. But according to new research led by Earth system scientists, some parts of the Arctic are getting deeper snowpack than ...
June 21, 2023 As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by ...
Mar. 31, 2022 For a long time, ecologists assumed tree rings to be absent in tropical trees because of a lack of temperature and rain fluctuations in the trees' environment. But in recent decades, the ...
Dec. 14, 2023 A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the ...
