Microfossils show promise in prospecting climate history

In 2004 and now in 2005, the hurricane seasons have been horrifyingly intense so how bad is the long-range forecast? Based on a century of data, meteorologists currently believe that a 30-year lull in hurricane activity is over and we are at the beginning of a new multi-decade period of larger and more frequent storms. However, there is other data that suggests we may also be coming to the end o...

'Acid rain' and forest mass: Another perspective

A few years ago the study of the effects of atmospheric deposition on forest ecosystems reached beyond the scientific sphere and the term "acid rain" was coined. This problem, which ignores frontiers, happens because, due to the burning of fossil fuels, the amount of sulphur and nitrogen oxides in the atmosphere is greater than that derived from natural processes. These oxides, in the presence o...

Emerald Spectre haunts Ontario's ash forests

A new study shows that while we're winning isolated battles, we could well lose the war to prevent the devastating spread of the emerald ash borer in eastern Canada and the United States. It's a failure that would cost billions of dollars in lost timber and ornamental trees, and dramatically change the forest and neighbourhood landscape in eastern North America with even more impact than Dutch e...
