Climate Change

Ice streams are moving huge amounts of ice into the oceans from the centre of Antarctica-a continent three-quarters as large as North America.

The possibility of a substantial sea level change was made all too clear in a recent article in Climate Alert, the newsletter of the prestigious Climate Institute of Washington, DC. In that publication, researchers examined the potential for a breakup of the already two-thirds-collapsed west side of Antarctica, the West Antarctic Ice Sheet (WAIS), and the chance of a six-metre increase in the global sea level.

Reading Stormy Weather is an inspiring and invigorating experience that we wanted to share with our readers in the excerpts that follow. In dozens of short segments, the authors outline practical and do-able steps for changing from a fossil fuel economy to new technologies -- solutions for citizens organizations, governments from town to federal, businesses and organisations, energy and automobile companies, and, of course, for individuals.

So far the climate change models omit the effects of trees and plankton.

As we enter 2002, let's examine our understanding of the science and politics of climate change. In November 1989, Dr. Gordon McBean, then a UBC geography professor and a lead author of the first report of the Intergovernmental Panel on Climate Change (IPCC), was giving a speech at the Vancouver Court House just prior to the release of the 1st IPCC Scientific Assessment.

The greenhouse effect is not a static process. It only seems that way because the past 10,000 years have been so stable. But this is not the way the world's climate works. If you think the enhanced greenhouse effect is troublesome, wait until the runaway greenhouse effect kicks in. As the saying goes, "You ain't seen nothin' yet."

Both the Pacific Coast and the South BC Mountain regions received more than 30% less moisture than normal. And when it did rain in those regions, in some cases higher than average amounts, it came all at one time which is hardly the type of precipitation beneficial to growing crops. As the climate changes so should your plans in the garden.

Once winter is upon us it can be difficult to make good, conscious plans to change our gardens for next year's growing season. Even if we winter garden, we must plan carefully now, not just where to plant our crops, but also which varieties will do best in increasing summer heat and longer growing seasons.

Diplomacy is traditionally a game of alliance and compromise. Yet, in the early hours of Saturday, 11 Decem­ber, Bolivia found itself alone against the world, the only nation to oppose the outcome of the United Nations cli­mate change summit in Cancun. We were accused of being obstructionist, obstinate and unrealistic. Yet, in truth we did not feel alone, nor are we of­fended by the attacks. Instead, we feel an enormous obligation to set aside diplomacy and tell the truth.

Mainstream climate scientists agree (with some exceptions and quibbles) that Earth's climate is changing, that humans are helping turn up the heat, and that the changes may cause serious damage.

In view of this often-repeated consensus, which has become a boring truism, why do political/economic leaders of industrial countries fall short of effective action to reduce the danger? The authors of Ice Chronicles do not frame the question in such stark terms; they lean over backwards to be cautious and

Five years ago a group of leading biologists met at Willach in Austria to discuss how much global warming plants and animals could stand. One degree Celsius per century was their estimated maximum.

What is the extent of our understanding how climate change will impact water supplies in British Columbia? The Canadian Water Resources Association stated that the “incidence of extreme hydrological events and new and unforeseen climatic records is on the increase…” A few communities are
