Papaver radicatum (arctic poppy), a flowering plant of the Arctic tundra follows the sun around the sky during the 24-hour daylight of summer north of the Arctic Circle. Changing climate conditions are amplified in polar regions and northern high-latitude areas are projected to warm at twice the rate of the global average. [1]
Krummholz Pinus albicaulis in Wenatchee National Forest Wind-sculpted krummholz trees, Ona Beach, Oregon. Krummholz (German: krumm, "crooked, bent, twisted" and Holz, "wood") — also called knieholz ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds.
The effect is notably found in arctic and alpine permafrost sediments, and occurs where the air temperature falls below 0°C (the freezing point of water) followed by a rapid drop in soil temperature. [1] Because of this effect, the lowering of temperature in moist, cold ground does not happen at a uniform rate.
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest ) and tundra . [ 2 ]
That is the case Sophie Howarth puts forward in her new book, Looking at Trees, published by Hoxton Mini Press, which compiles more than 100 delightful pictures of trees from photographers all ...
David George Barber, OC FRSC (28 November 1960 – 15 April 2022) [1] was a Canadian environmental scientist and academic known for his contributions to Arctic science, in particular the study of Arctic sea ice processes. [2] He held the Canada Research Chair in Arctic-System Science at the University of Manitoba. [3]
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
