Live Chat: Spring Forward--The Ecological Impact of Climate Change on the Seasons
14 March 2012 7:36 am
See below for the chat box. Join us each Thursday at 3 p.m. EDT for a live conversation with leading scientists and expert reporters.
The cherry blossoms in Washington, D.C., have been arriving ever earlier over the past 100 years—just another indication of how global warming is altering the timing of the seasons. All sorts of signs of spring are arriving ever earlier, and summer and fall are also undergoing changes.
What do these changes mean for plants, hibernating animals, migrating birds, or honeybees and other pollinating insects? Which parts of the world are in for the biggest changes? And what can we expect from further climate change?
Join us for a live chat at 3 p.m. EDT on Thursday, 15 March, on this page. You can leave your questions in the comment box below before the chat starts.

David Inouye is an ecologist at the University of Maryland. Since 1973, he has researched the timing (phenology) and abundance of flowering of about 100 species of wildflowers in the Rocky Mountains. He studies how they respond to climate change, and the consequences of their responses for plant communities and interactions with pollinators.
Ecologist Jake Weltzin directs the USA National Phenology Network, which coordinates scientists, land managers, policy-makers, and the public to help assess how global change affects the natural world. He has studied grasslands, woodlands, and other ecosystems.
