Small ethanol plants key to efficiency: Canada

OTTAWA (Reuters) – Building more and smaller ethanol plants could help overcome concerns that production of the biofuel consumes more in energy than it provides, Canadian Agriculture Minister Gerry Ritz said on Friday.

One of the reasons so much energy is used to make ethanol is that trucks travel long distances carrying corn, chaff or other plant material to ethanol plants.

“Smaller and locally owned I think are the right way to go,” Ritz said as he kicked off debate in the House of Commons on the final stage of a bill that would ensure that gasoline contains 5 percent ethanol by 2010.

UN urges biofuel investment halt 
 
Palm oil is one of the biofuel crops stirring controversy.

The UN’s new top adviser on food has urged a freeze on biofuel investment, saying the blind pursuit of the policy is “irresponsible”.

Olivier de Schutter also wants curbs on investors whose speculation is, he says, driving food prices higher.

UN officials liken the rise in food prices to a silent tsunami, threatening 100 million of the world’s poorest.

Climate change warms Arctic, cools Antarctica

WASHINGTON (Reuters) – The Arctic and Antarctica are poles apart when it comes to the effects of human-fueled climate change, scientists said on Friday: in the north, it is melting sea ice, but in the south, it powers winds that chill things down.

The North and South poles are both subject to solar radiation and rising levels of climate-warming greenhouse gases, the researchers said in a telephone briefing. But Antarctica is also affected by an ozone hole hovering high above it during the austral summer.

“All the evidence points toward human-made effects playing a major role in the changes that we see at both poles and evidence that contradicts this is very hard to find,” said Jennifer Francis, an atmospheric scientist at Rutgers University in New Jersey.

Rain and snow spell relief for Great Lakes

TORONTO (Reuters) – Twice as much autumn rain and early winter ice helped Lake Superior, the biggest of North America’s Great Lakes, bounce back from record low water levels reached last year.

The deep, cold lake on the Canada-U.S. border — the largest freshwater body of water in the world by surface area — rose about 31 cm (1 foot) in seven months, with half of that in April alone as the spring thaw melted heavy winter snowfall that arrived late in the season.

The turnaround in the uppermost of the Great Lakes could literally trickle down to its four lower cousins, spelling relief for shippers who use the major waterway and residents concerned over shallow channels and receding shorelines.
