Beginning in the early 1980s, a constellation of Ea rth-observing satellites has provided a unique vantage point for observing the remote and dynamic Arctic tundra biome—the treeless environment encircl ing most of the Arctic Ocean. The satellite record shows that the productiv ity of tundra vegetation has increased since the late 20th century, a pheno menon commonly referred to as “the greening of the Arctic.” Trends in tundr a productivity, however, have not been uniform in direction or magnitude ac ross the circumpolar region and there has been substantial variability from year to year. This variability arises from a web of complex interactions t hat link the vegetation, atmosphere, sea-ice, seasonal snow cover, ground ( soils, permafrost, and topography), and animals of the Arctic system. In th is talk JJ will begin with an overview of the tundra biome and address the questions: what are the drivers of Arctic vegetation change?

Seminar Abstract:

Arctic la nds and seas have experienced dramatic environmental and climatic changes i n recent decades, and the pace of change is expected to accelerate in the f uture. Beginning in the early 1980s, a constellation of Earth-observing sat ellites has provided a unique vantage point for observing the remote and dy namic Arctic tundra biome—the treeless environment encircling most of the A rctic Ocean. The satellite record shows that the productivity of tundra veg etation has increased since the late 20th century, a phenomenon commonly re ferred to as “the greening of the Arctic.” Trends in tundra productivity, h owever, have not been uniform in direction or magnitude across the circumpo lar region and there has been substantial variability from year to year. Th is variability arises from a web of complex interactions that link the vege tation, atmosphere, sea-ice, seasonal snow cover, ground (soils, permafrost , and topography), and animals of the Arctic system. In this talk JJ will b egin with an overview of the tundra biome and address the questions: what a re the drivers of Arctic vegetation change? What types of change would be a pparent to an observer on the ground? And, what are the consequences of the se changes for Arctic residents and the rest of the globe? JJ will explore these questions through the lens of the satellite record, field studies, an d the rich knowledge-base of Arctic residents to understand the drivers and impacts of ecological change in the Arctic tundra biome.

The ARCUS A rctic Research Seminar Series invites leading Arctic researchers and commun ity leaders to share the latest findings in Arctic research and what they m ean for decision-making. The events are free and open to the public, and wi ll be of particular interest to the international Arctic research community , Arctic educators, non-governmental organizations, federal agency official s, and the public.

For those on Twitter, we invite you to join us in live-tweeting the event using the hashtag #arcuswebinar.
