High in the Alps at more than 3000 m/9700 ft, botanists re-establish plots, set up and inventoried ten years before, to see how climate warming has affected alpine plants. The regional average temperature is up 1.2 C/2.0 F in the last 30 years, and wildflowers and grasses adapted to colder elevations are being forced up the mountain. Botanist Harald Pauli who, with colleagues from University of Vienna, set up the original study, counts individual plants and compares their location with the photos made in 1994. Other effects of climate change can be seen on the glaciers behind.
