Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:
Tipping, tipping ... And Thar She Goes! As Arctic summer ice likely disappears by 2022, most Arctic experts say, after being taken aback by the swiftness of this summer's record-breaking melt, reports Fen Montaigne at Environment360. Most experts now agree that the polar summer ice is beyond the point of return, and consequences will be profound, including significant changes in weather patterns for the U.S. and other countries in the northern hemisphere. And you thought 2012 was interesting....
Global Warming Is Real! says an organization of American weather broadcasters, the American Meteorological Society, reports Joe Romm at ClimateProgress. Important, since most Americans rely on and trust their weather broadcasters on weather and climate -- and most Americans want to learn more about climate change from them.
Hot Times in Siberia: Record wildfires in Siberian forests and boglands have burned close to a half million acres during their unusually hot summer, reports Brian Dunbar at the National Atmospheric and Space Administration website. Hotter times for all of us, since the wildfires' huge emissions of carbon dioxide further accelerates global warming..."

The cool La Niña phase of the cyclically variable Southern Oscillation of tropical temperatures has been dominant in the past three years, and the deepest solar minimum in the period of satellite data occurred over the past half dozen years. We conclude that the slowdown of warming is likely to prove illusory, with more rapid warming appearing over the next few years."

Democratic Party Platform Engages Climate Change. I'm still waiting to see if the Republican platform makes any attempt to quantify climate change as an issue, or if it ultimately gets swept under the rug. Here's an overview of the Democratic position on climate change from getenergysmart.com: "In contrast to its total absence from the Republican Party platform (as a sign of the GOP’s anti-science global warming denial), the Democratic Party platform directly engages on climate change issues — with the term appearing 18 times in the platform.
Not surprisingly, the environment section has direct discussion of climate change issues.
We know that global climate change is one of the biggest threats of this generation – an economic, environmental, and national security catastrophe in the making. We affirm the science of climate change, commit to significantly reducing the pollution that causes climate change, and know we have to meet this challenge by driving smart policies that lead to greater growth in clean energy generation and result in a range of economic and social benefits."
