Now you can read in full the IPPC’s report from Working Group II on Climate Change Impacts, Adaptation, and Vulnerability. Find it here.

The report’s release coincides with eerie hints of our future in resource management. The water level of the Great Lakes — the largest freshwater reservoir in the world — has been unusually low recently. This is not entirely due to climate change, but is very likely exacerbated by it.

If you go to page 628 of the full report (page 12 of the North American chapter), you’ll be treated to a terrific chart on the interconnected impacts of increasingly low water levels in the Great Lakes (reprinted below). Impacts include decreased potential for hydropower, loss of habitat and species, difficult navigation, and issues with water quality and water access.

If you’re looking for general background on the IPCC report, you can follow Climate Progress’s coverage of this Working Group’s Summary for Policymakers, released in April. Here’s a post anticipating the Summary for Policymakers and then a three-part summary of the Summary for Policymakers: Part I, Part II, and Part III.

A somewhat more technical resource on the full report is Real Climate’s review, found here: Regional Climate Projections.

    Joe,
    It would be interesting to compare lake levels to the known 20th century warming and cooling periods. The linked article seems to discount GW as the cause for lower lake levels, which do rise and fall over time. Please indulge some family history. Way back in 1919, my great grandparents built a cottage on the Michigan shore near Benton Harbor. The lake was then at or near its historic low. There was almost a quarter mile of beach between the tree line and the water with a sandbar large enough for touch football games 15 – 20 yards offshore. By the time of my childhood in the Fifties, about 1/4th of the beach was gone and the sandbar was covered by six inches of water. By the late seventies the beach had pretty much disappeared. I don’t know when the lake level peaked, but is has been falling for a few years.

    I for sure would love to see the calorie count on fast food items. I am always on the go and sometimes fast food is my only choice, so I just guess at which item has the least calories. And I’m not always right! I thought I was doing good with a chicken BLT salad from wendys and that has more calories than a burrito from taco bell!
