Marine ecosystems are centrally important to the biology of the planet, yet a comprehensive understanding of how anthropogenic climate change is affecting them has been poorly developed.The impacts of anthropogenic climate change so far include decreased ocean productivity, altered food web dynamics, reduced abundance of habitat-forming species, shifting species distributions, and a greater incidence of disease. Although there is considerable uncertainty about the spatial and temporal details, climate change is clearly and fundamentally altering ocean ecosystems. Further change will continue to create enormous challenges and costs for societies worldwide, particularly those in developing countries.

Are hungry kids a priority for the Harper government? by Larry Powell The forum (for the riding of Dauphin - Swan River - Neepawa) was sponsored by the Mission and Services Committee of the Neepawa United Church. It drew about 80 people to the church on Wednesday. But only four of the five candidates (see below) took part in the debate -  Ray  Piché  (Liberal),   Kate Storey (Green Party),  Inky Mark (Ind.) and  Laverne Lewycky (NDP) . The 5th candidate, the sitting Conservative MP for the area, Robert Sopuck (represented by the empty chair on the right), did not attend. His office manager in Neepawa, Christine Waddell, said he was in Inglis, a small community in the western part of the riding for the evening. She did not elaborate. But she did explain that a campaign worker was mistaken when he told forum organizers earlier that Mr. Sopuck would, in fact be there. Piché , the Liberal candidate, said the MP's absence showed “disrespect” for the rest of the candidates

A Candidate's Forum on Child Poverty Touches a Nerve in Manitoba.

by Larry Powell Planet In Peril has sorted through some of the confusion surrounding the absence of Robert Sopuck (above), the Conservative Member of Parliament for Dauphin-Swan River-Neepawa,  from a candidates' forum on child poverty in Neepawa on Wednesday.  About a month ago, his office told forum organizers that he would be attending.  But his office manager in Neepawa, Christine Waddell, later announced he could not attend due to "scheduling conflicts." She said the night of the event, he was in Inglis, a small town in the western part of his riding.  This morning, however, Sopuck himself told PinP he had actually been in Roblin, a larger town just north of Inglis. A newspaper ad indicated it was a "meet and greet" affair. But that was in the morning in Roblin, a town within a 3-hour drive of Neepawa. So it's still not clear what the event in Inglis was which took priority over a candidate's forum. The MP bristled at my suggestion th
