Global climate change crosses state boundaries

Article Abstract:

Climate concerns have forced state governments to establish task forces to suggest possible state action via comprehensive energy conservation and efficiency strategies. Iowa, Washington and Connecticut have been in the forefront in implementing legislation on climate change issues. Illinois has initiated a climate change research program that focuses on the pertinent theme of scientific uncertainties. Both the states and the US are likely to benefit from the former's active participation in issues pertaining to changes in global climate.

Climate change history stored in Greenland ice

Article Abstract:

Drilling of ice samples in Greenland under the European Greenland Ice Core Project and the Greenland Ice Sheet Project have furnished climatic change history from as far back as 250,000 years. Core sampling reveals distinct epochs of moderate conditions followed by sudden warming and gradual cooling. The ice cores also reveal evidence of changes in the atmospheric concentration of carbon dioxide and methane. The current significant levels of these greenhouse gases forebode further shifts in global climatic conditions in the near future.

Downwind, downstream: multicountry megaprojects remediate pollution seeping across national boundaries

Article Abstract:

Multicountry environmental remediation projects usually face tremendous social, political and technological difficulties which are usually similar in complexity to diplomatic negotiations for changing international trade policies or ending regional disagreements. Two examples of such megaprojects are the restoration of the dried-up Aral Sea by former Soviet Union countries and the US-Canadian clean-up of the Great Lakes-St. Lawrence River basin.
