Returning to the lab near Crested Butte to meet with biologists studying climate change and its affects on plants and animals living at high altitudes in Colorado. Story is part of Jim Erickson's climate project. Will be meeting with biologists David Inouye of the University of Maryland and John Harte of the University of California at Berkeley. Inouye has been monitoring plots of flowering plants at the Rocky Mountain Biological Lab since 1973. He is seeing evidence that flowers are blooming earlier in recent years, possibly due to earlier snow melt. He was also the lead author of the paper that tied marmot behavior, earlier arrival of robins, and change in timing of plant flowering to global climate change. David Harte established the meadow-warming experiment more than a decade ago. It was one of the earliest field experiments to simulate global warming. Heaters increase the temperature of the meadow by 3 degrees -- around the clock and 365 days a year. Different mixes of plants have moved into the meadow over the last decade, providing a glimpse into the future of the Gothic area in a warmer world.
