Driven by Warming, Plants in Western Europe are Climbing to Higher Altitudes

To escape warming temperatures, some plants are taking up residence in higher, cooler locales, but the upward climb of these forest plants could disrupt mountain ecosystems, says new research in the 27 June issue of Science.Jonathan Lenoir and his research team surveyed 171 plant species in Western Europe and found an average upward shift of 29 meters per decade, give or take about 11 meters. The shift happened over the course of the 20th century, with the steepest climb occurring between 1971 and 1993, when the average shift was nearly 65 meters per decade.

Study Shows Human-Caused Climate Change Responsible for Global Impacts

Study Shows Human-Caused Climate Change Responsible for Global Impacts

A vast array of physical and biological systems across the earth are being affected by warming temperatures caused by human activity, says a new Columbia study. These impacts include earlier leafing of trees and plants over many regions; movements of species to higher latitudes and altitudes in the Northern Hemisphere; changes in bird migrations in Europe, North America and Australia; and shifting of the oceans’ plankton and fish from cold- to warm-adapted communities. Based on an analysis of aggregated data, this study is the first to link observed global changes in diverse systems to human-caused, or anthropogenic, climate change. The study appears in the May 15 issue of the leading scientific journal Nature.

Facing an "Extreme Future," Nations—and Researchers—Must Collaborate, Experts Say

With the world facing stresses on energy, water, food supplies and social services that seem destined to grow more dire, 21st century science will have to adopt new, more global approaches in organization and funding to provide solutions, experts told an 8 May session of the 33rd annual AAAS Forum on Science and Technology Policy.
