Arctic plant study reveals an ‘early warning sign’ of climate change upheaval

 Scientists studying Arctic plants say the ecosystems that host life in
some of the most inhospitable reaches of the planet are changing in
unexpected ways in an “early warning sign” for a region upended by
climate change.

In four decades, 54 researchers tracked more than 2,000
plant communities across 45 sites from the Canadian high Arctic to Alaska
and Scandinavia. They discovered dramatic shifts in temperatures and
growing seasons produced no clear winners or losers. Some regions witnessed
large increases in shrubs and grasses and declines in flowering plants –
which struggle to grow under the shade created by taller plants.

Those findings, published in Nature, fill key knowledge gaps for teams on the
frontlines of a changing climate.
