TLDR
In this paper, the authors used ground observations, remote sensing, and analysis of the atmospheric CO2 signal to estimate the progression of vegetation activity in the spring season, and found that the correlation between estimates of the initiation of spring activity derived from ground observations and remote sensing at interannual time scales is often weak.Abstract:
Summary
Climate change effects on seasonal activity in terrestrial ecosystems are significant and well documented, especially in the middle and higher latitudes. Temperature is a main driver of many plant developmental processes, and in many cases higher temperatures have been shown to speed up plant development and lead to earlier switching to the next ontogenetic stage. Qualitatively consistent advancement of vegetation activity in spring has been documented using three independent methods, based on ground observations, remote sensing, and analysis of the atmospheric CO2 signal. However, estimates of the trends for advancement obtained using the same method differ substantially. We propose that a high fraction of this uncertainty is related to the time frame analysed and changes in trends at decadal time scales. Furthermore, the correlation between estimates of the initiation of spring activity derived from ground observations and remote sensing at interannual time scales is often weak. We propose that this is caused by qualitative differences in the traits observed using the two methods, as well as the mixture of different ecosystems and species within the satellite scenes.read more

Influences of species, latitudes and methodologies on estimates of phenological response to global warming
TL;DR: In this paper, a meta-analysis spanning 203 species was conducted on published datasets from the northern hemisphere, showing that the difference in estimated response is primarily due to differences between the studies in criteria for incorporating data.

A globally coherent fingerprint of climate change impacts across natural systems

TL;DR: A diagnostic fingerprint of temporal and spatial ‘sign-switching’ responses uniquely predicted by twentieth century climate trends is defined and generates ‘very high confidence’ (as laid down by the IPCC) that climate change is already affecting living systems.

Increased plant growth in the northern high latitudes from 1981 to 1991
TL;DR: In this paper, the authors present evidence from satellite data that the photosynthetic activity of terrestrial vegetation increased from 1981 to 1991 in a manner that is suggestive of an increase in plant growth associated with a lengthening of the active growing season.
