Hello, Mary! Well, as you can imagine, the subject of global warming is not without controversy! However, there does seem to be some consensus, although it is by no means unanimous, that human activity is indeed contributing to some overall warming of the climate. So, will this prevent the next ice age (which is now thought to be some 10,000 years away, more or less)? Probably not; it may even hasten its arrival, due to shifts in ocean currents! Or it may make no difference whatsoever; there is some thought that the ice ages depend more on fluctuations in solar output than anything else. In this case anything we could do locally (on the earth, that is) would have little effect. Here are some Web pages on the subject: First, there will be a conference on Global Warming and The Next Ice Age in August 2001; you might want to keep an eye out for the proceedings. Here's the conference announcement: http://www.atm.dal.ca/announcement4.htm And now some articles: Global Warming Could Trigger Ice Age http://www.monitor.net/monitor/free2/oceancollapse.html Global warming could lead to another ice age. http://earthobservatory.nasa.gov/Study/PolarParadox/ The Warming of the Earth A beginner's guide to understanding the issue of global warming http://www.whrc.org/globalwarming/warmingearth.htm Global Climate Change ("Global Warming") http://janus.state.me.us/dep/air/global.htm A new European ice age? http://naturalscience.com/ns/cover/cover5.html Freezing future There's now alarming evidence that Europe is facing an ice age http://www.newscientist.com/global/global.jsp?id=22140300 Latest News on Global Warming, from the New Scientist http://www.newscientist.com/global/global.jsp
