TLDR
In this paper, remote sensing data indicate that contemporary climate warming has already resulted in increased productivity and increased productivity in the tundra biome (Tundra Tundra Bi biome).Abstract:
Temperature is increasing at unprecedented rates across most of the tundra biome(1). Remote-sensing data indicate that contemporary climate warming has already resulted in increased productivity ov ...read more

Vulnerability and resilience of the carbon exchange of a subarctic peatland to an extreme winter event
Frans-Jan W. Parmentier,Daniel P. Rasse,Magnus Lund,Jarle W. Bjerke,Bert G. Drake,Simon Mark Weldon,Hans Tømmervik,Georg Hansen +7 more
TL;DR: In this paper, the authors report eddy covariance fluxes of CO2 from a peatland in northern Norway and show that vegetation CO2 uptake was delayed and reduced in the summer of 2014 following an extreme winter event earlier that year.

Shrub decline and expansion of wetland vegetation revealed by very high resolution land cover change detection in the Siberian lowland tundra
Rúna Í. Magnússon,Juul Limpens,David Kleijn,Ko van Huissteden,Trofim C. Maximov,Trofim C. Maximov,Sylvain Lobry,Monique M. P. D. Heijmans +7 more
TL;DR: In this article, the authors quantified changes in land cover and transition probabilities in a representative tundra site in the Indigirka Lowlands using a timeseries of three very high resolution (VHR) (0.5 m) satellite images acquired between 2010 and 2019.

TL;DR: These findings indicate that C, recently fixed by trees and tall shrubs, makes a substantial contribution to soil respiration, and it is critically important that these processes are taken into consideration in the context of a greening arctic.

Biotic forcing: the push–pull of plant ranges
TL;DR: General predictions about the biotic envelopes of plants, and how climate change will alter these envelopes, are provided, while highlighting uncertainties in applying these predictions beyond range edges.

Controlling the false discovery rate: a practical and powerful approach to multiple testing
Yoav Benjamini,Yosef Hochberg +1 more
TL;DR: In this paper, a different approach to problems of multiple significance testing is presented, which calls for controlling the expected proportion of falsely rejected hypotheses -the false discovery rate, which is equivalent to the FWER when all hypotheses are true but is smaller otherwise.

Rapid Range Shifts of Species Associated with High Levels of Climate Warming
TL;DR: A meta-analysis shows that species are shifting their distributions in response to climate change at an accelerating rate, and that the range shift of each species depends on multiple internal species traits and external drivers of change.

TL;DR: In this article, the NDVI 8-km equal area dataset from July 1981 through December 2004 for all continents except Antarctica was used to produce a Normalized Difference Vegetation Index (NDVI) 8.
