Weather squeezes Great Lakes

Historic low water levels are an emerging concern for shippers and everyone else who uses the St. Lawrence River and the Great Lakes. The St. Lawrence was more than a foot lower than normal last fall. Lakes Michigan and Huron are even worse. The water is so low that 1000-foot cargo ships are running aground. The issue appeared on Governor Spitzer's radar last week in his State of Upstate speech. He called on the legislature to pass the Great Lakes Compact, which would limit water diversions out of the Lakes. Illinois and Minnesota are the only states to ratify the compact so far. All eight Great Lakes states must pass it before it can go before Congress for final passage. Drought in the southeast and southwest are adding new urgency to the compact. There's debate about whether the low water levels are just part of the historic ups and downs of the Great Lakes, or if it's the effects of global warming. Lester Graham reports from Lake Michigan's Muskegon River, a trouble spot for some of the big ships.  Go to full article

Hydrogen from hydro power planned for Olympic village

Across the North Country, there are dozens of old dams and millponds sitting unused. A century ago, they provided vital hydro-power for the region's industries. Now the mayor of Lake Placid hopes to see a dam on one Adirondack river brought back to life. The goal is to put the Olympic village on the cutting edge of the new post-oil economy, testing a new system for producing environmentally friendly hydrogen. Independent producer Jacob Resneck has our story.  Go to full article

Ottawa lawmaker braces for global warming

Many people think of climate change as a national, even international, problem. But a growing number of local officials are beginning to see it as a local problem as well. Census figures show that more and more North Americans are now living in cities. For those who want to fight climate change, that means changing the way these urban folks live. Karen Kelly has the story of one Ottawa city councilor who's made that his mission.  Go to full article

Water levels a concern along Seaway

Boaters and businesses along the St. Lawrence River and Lake Ontario are suffering through lower-than-normal water levels this summer. Earlier this month, freighters on the St. Lawrence were cautioned to go slow because of low water. The low water is expected to prompt high turnout at a summit meeting called by the International Water Levels Coalition at the Clayton Opera House Saturday morning. Local conditions depend partly on how much water is coming downstream from Great Lakes at the head of the seaway system in the Midwest. There's increasing concern about lower water levels all along the Great Lakes system, both due to increased drainage, and possibly global climate change. Chuck Quirmbach has more.  Go to full article

Climate Change will alter Northeast

40 scientists from across the Northeast have collaborated to project the region's climate through the end of the century. The conclusion of the Northeast Climate Impacts Assessment, released last June, is that the very character of the Northeast is in danger. Cameron Wake is one of the team's co-leaders. He's a researcher at the University of New Hampshire's Climate Change Center. Wake told David Sommerstein the scientists used two future scenarios.  Go to full article

Climate Change: Will CO2 help farms?

For years, researchers studying the effects of climate change on agriculture have focused on two big issues: the availability of water and the impact of increasing carbon dioxide levels in our atmosphere. Carbon dioxide released from our cars and factories is the number one cause of global warming. But scientists have long theorized that more of the gas in the atmosphere could actually help grow bigger plants. New research is challenging that assumption. David Sommerstein went to the breadbasket in Illinois to learn more.  Go to full article

Canada CO2 plan called scam

Canada's conservative government recently unveiled the final details of its long awaited policy on fighting climate change... and it says it will not meet its Kyoto targets. And as Dan Karpenchuk reports, so far the proposed $8 billion policy has been a tough sell.  Go to full article

Global warming on the farm: adaptation and risk

The global scientific community has reached consensus - the Earth's climate is getting warmer and humans are a major cause of it. Most of the country is projected to experience milder winters, more hot summer days, and stronger storms. This week we're looking at how global warming will affect the North Country. It's already affecting agriculture, the region's biggest industry. Plants are sprouting sooner. New crops are being sown. But fields are flooding more often. And new pests are taking hold. Farmers who adapt can take advantage of the changes, but the financial risks are great. David Sommerstein reports.  Go to full article
