Arctic Heads Into Warmer Future

<b>Arctic Heads Into Warmer Future</b><br /><br />LINK<br /><br />The Arctic is undergoing rapid and possibly irreversible change, according to a new report prepared for the eight nations which rim the region. <br /><br />The Arctic Climate Impact Assessment (ACIA) endorses recent warnings about melting ice, with perhaps all ocean ice disappearing in summers by 2060-2100. <br /><br />The statement, to be published next week, has concerns too about raised levels of ultraviolet light brought about by ozone thinning. <br /><br />It says the coming years will challenge the region's ecosystems and peoples. <br /><br />The ACIA document recognises that average Arctic temperatures have risen at twice the rate seen elsewhere on the planet. It records that permafrost is thawing, trees are moving north and some species, such as polar bears, are having to adapt their ways to survive the changing conditions. <br /><br />Global impact<br /><br />The report does not list simply the negatives that will come from a warmer world. It also says agriculture may become easier in some areas, there should be improved access to oil and gas deposits and new shipping lanes will open up. Some fisheries could become more productive. <br /><br />The ACIA document is the work of about 250 scientists and six circumpolar indigenous peoples' organisations and has taken four years to compile and has undergone a rigorous peer-review process. <br /><br />It is perhaps the most detailed study ever of how current warming trends are changing a single region of the Earth. <br /><br />It was commissioned by the Arctic Council, the intergovernmental forum for countries with territories inside the region's 30 million square km: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the US. <br /><br />"The starting point for the assessment was the recognition that the Arctic was vulnerable in many different ways to climate change, and also that the A

Has anyone ideas on how to reduce CO2 emissions except at very high cost? I suspect it is less costly to trap natural CO2 emissions. CO2 can be pumped deep under ground, to be released if we get new ice age shortly after or instead of green house warming. Neil
