Earth Talk: Losing Winter

From the Editors of E/The Environmental Magazine
Dear EarthTalk:
The 2008 Summer Olympics in China are drawing a lot of attention right now for political reasons. I’ve heard, though, that one ray of light is China’s effort to make the event as green as possible. What’s going on in that regard?

It’s true that China is using the upcoming Beijing Olympics as a sustainability showcase, going so far as to dub the event the “Green Olympics.” Through a partnership with the U.S. government and the Maryland-based International Center for Sustainable Development, China is giving Beijing a green makeover to make the city a model for net zero pollution, green building and sustainable community development.
According to China’s Technology Minister Wan Gang, the Beijing Olympics are expected to generate some 1.2 million tons of carbon dioxide, in large part because of the flying the world’s athletes will do to get to and from the games. To offset these potent greenhouse gases, China will take a series of measures, Wan says, including planting trees, closing 1,000 small coal mines before and during the games and banning up to a million cars from city streets.
Beijing’s Olympic Village, where the Chinese government has been busy erecting dozens of stadiums and other structures according to rigorous green standards, is emerging as quite an example of sustainable community development. The steel-looped Beijing National Stadium, for instance, includes a rainwater collection arrangement, a natural ventilation system and a clear roof with inflatable cushions made from ETFE (Ethylene Tetrafluoroethylene), a kind of plastic that increases light and heat penetration.
Another example is the “Water Cube,” a spectacular-looking structure that looks like a building made of bubble-wrap. Officially known as the National Aquatics Center, it is completely surrounded with ETFE pillows and is expected to cut energy use by 30 percent. And when it has finished serving its purpose as an Olympic venue, it has been built to be converted to a shopping area and leisure center with tennis courts, retail outlets, nightclubs and restaurants.
All seven main Olympic stadiums are equipped with solar generators capable of outputting 480 kilowatts of energy at any given moment. Ninety percent of the lighting outside the stadiums, as well as the entire hot water supply for the Olympic Village will be powered by solar energy. Also, the main stadiums will receive power from Beijing’s first wind farm.
While the Olympic Games will only last for two weeks, environmentalists hope the greening of Beijing will indeed continue beyond the summer ‘08. Some proposals include building 14 wastewater treatment facilities to achieve 90 percent treatment rate in Beijing, and extending potable water to the entire city.
Also, the municipal government of Beijing has invested in expensive energy-efficient heating and transportation equipment that will greatly improve environmental quality for decades hence. Beijing, where 1,000 new cars roll onto the streets every day, also plans to source clean energy from other parts of China and through the purchase of pollution offsets on a quickly expanding international market.

Dear EarthTalk:
How is it said that we are “losing winter” because of climate change? It didn’t seem so last winter, when it even snowed in places for the very first time.
Peter Kim, Duxbury, MA
The effects of global warming manifest themselves differently in different locations, and winter is no doubt getting shorter and warmer across New England, the Canadian Maritimes and Northern Europe.
In New England, average winter temperatures have increased 4.4 degrees Fahrenheit since 1970. The years 2006 and 1998 were the first and second warmest years on record in the U.S. since we started counting, with the last eight five-year periods the warmest in history. According to the National Climatic Data Center, that warming has been accelerating over the last three decades, from just over a tenth of one degree Fahrenheit per decade to almost a third of a degree now.
By 2100, temperatures in the Northeastern U.S. are predicted to have risen by 8-12 degrees Fahrenheit, with the number of snow days half of what we are used to now. A recent study by the Union of Concerned Scientists on the effects of global warming in the Northeast concluded that, under some scenarios, “Only western Maine is projected to retain a reliable ski season by the end of the century, and only northern New Hampshire would support a snowmobiling season longer than two months.”
And it seems that as one moves farther north, more and more winter is lost. The Arctic Climate Impact Assessment of 2004 reported that Arctic temperatures are now rising at nearly twice the rate of the rest of the world (as much as 14 degrees Fahrenheit over the next 100 years), reducing sea ice and melting frozen soils. It’s been widely reported that Alaska’s polar bears are probably doomed by 2050, but the scale of this climatic shift will likely do much more—completely changing the culture of the Arctic.
Global warming impacts are far from monolithic: Some parts of the planet are heating up and others are experiencing colder than average temperatures and record snowfalls, just as climate models predict. But the overall trend is clear: It’s getting warmer, and winter is losing intensity and duration. “If you’ve ever enjoyed ice skating, sledding, skiing, snowboarding or building a snowman, writes E – The Environmental Magazine, you should know that the future of these enshrined institutions is by no means guaranteed.”
Winter’s retreat may be sad for children intent on sledding, but it also augurs badly for the economy, especially for businesses reliant on snow. New England’s ski industry has experienced sharp declines in the number of days their lifts are shuttling people up the mountain. Snowmaking machines, originally intended to just cover any slack left by Mother Nature, now operate to capacity throughout the winter.
And snowmobile manufacturers report a 50 percent drop in sales over the last decade as the number of snow-covered days diminishes. Yet another business casualty is New England’s maple syrup industry, which has been thwarted in recent years by early thaws which have depleted production capacity by as much as 50 percent. According to Tom McCrumm of the Massachusetts Maple Producers Association, there may no longer be a maple sugar industry in New England by 2100.
