Boreal Forests Store More Carbon than Tropical Forests

Report Calls for Global Climate Talks to Consider Boreal’s Impact

cbi-bsi-logo OTTAWA, Ontario—When the world thinks of forests and their value to offset global warming, tropical forests come to mind. A report released today shows that the global impact of Canada’s boreal forest, which stores nearly twice as much carbon per hectare as tropical forests, has been vastly underestimated.

“The Carbon the World Forgot” identifies the boreal forests of North America as not only the cornerstone habitat for key mammal species, but one of the most significant carbon stores in the world, the equivalent of 26 years of global emissions from burning fossil fuels, based on 2006 emissions levels. Globally, these forests store 22 percent of all carbon on the earth’s land surface.

“Past accounting greatly underestimated the amount and depth of carbon stored in and under the boreal forest,” said Jeff Wells, an author of the report. In addition to carbon storage in trees, organic matter accumulated over millennia is stored in boreal peatlands and areas of permafrost. Some of this boreal carbon has been in place for up to 8,000 years.

The boreal forest’s status as the most intact forest left on earth also offers a unique opportunity for plants and animals forced to adapt to shifting habitats. Most other habitats today are highly fragmented by human activity, creating a variety of additional obstacles for species survival.

In light of these findings, today’s report urges that international negotiations on carbon and forest protection consider ways to account for and protect the boreal.

“Any effective and affordable response to climate change should include preserving the world’s remaining, carbon-rich old-growth forests,” said Steve Kallick, director of the Pew Environment Group’s International Boreal Conservation Campaign. “This report makes clear that nations must look not just at the tropics but at all the world’s old-growth forests for climate change solutions.”

“Keeping that carbon in place by protecting boreal forests is an important part of the climate equation,” said Dr. Andrew Weaver, “If you cut down the boreal forest and disturb its peatlands, you release more carbon, accelerating climate change.” Dr. Weaver of the University of Victoria is a lead author for the United Nations Intergovernmental Panel on Climate Change, which was awarded the Nobel Prize.

“The collision of climate disruption and massive human degradation of ecosystems is seriously worrying globally,” said leading conservation biologist Dr. Stuart Pimm of Duke University. “These changes are surely novel in earth’s history.” Maintaining the boreal forest’s intactness will be critical to slowing ecosystem shifts and to providing migratory corridors for displaced wildlife.

“Conservation can be an important tool in the fight to mitigate climate change” said Larry Innes, Director of the Canadian Boreal Initiative. “International protocols and legislation need to create opportunities to maintain the carbon stored in intact boreal forest soils, peatlands, and wetlands while enabling indigenous and local communities to take a leadership role in determining how to best conserve not only carbon, but the full suite of ecological, cultural and economic values that the boreal forest represents.”

More than 1,500 international scientists led by authors for the United Nations’ Intergovernmental Panel on Climate Change recommended in 2007 that at least half of Canada's boreal forest be protected from further disturbance - in large part to keep both the boreal forest carbon bank and internationally significant wildlife habitats intact. Despite the current lack of international protocol, several Canadian First Nation, provincial, and federal governments have taken important steps to protect hundreds of millions of acres of Canada’s carbon rich boreal forest. In all, scientists are recommending that at least 300 million hectares be protected.

Conservative MP Absent From a Child Poverty Forum in Southwestern Manitoba.

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
