Thirty Million (direct Vimeo link), a U.N.-funded half-hour film about the expected effects of climate change on the country of Bangladesh. Radio interview with one of the directors on Radio New Zealand. Bangladesh will lose 70% of its land area if there is a one-meter sea level rise, displacing thirty million people. [more inside]
By comparison to what it could have been, it’s a miracle. By comparison to what it should have been, it’s a disaster. - A historic deal has been struck in Paris to reduce carbon emissions and reduce global warming, with a ceiling of 2 degrees centigrade and a goal of 1.5C. 2015 has been the hottest year on record.
Scripps Institute of Oceanography projects that next month its monitoring station will for the first time measure CO2 at 400 parts per million. Atmospheric CO2 has risen from 280 parts per million before the Industrial Revolution. 400 ppm is an arbitrary milestone that we'll blow right past on our way to 450 ppm within a few decades. This is an unprecedentedly fast rate of increase and it's getting faster. Not all measuring stations are exactly the same: A NOAA station in the Arctic measured CO2 at 400 ppm last year.

Dramatic and unprecedented plumes of methane have been have been seen bubbling to the surface of the Arctic Ocean. [more inside]
Building a Green Economy, Paul Krugman on the economics of Climate change.
A solar updraft tower generates electricity with nothing more than a greenhouse and a tall chimney. A 195 meter tall prototype in Spain cheaply operated at 50 kW for years. Now there are plans to build others, including a 40 MW tower, 750 meters tall (near twice as tall as the current tallest structure in the EU). Two others, a 200 MW tower in Australia (previously discussed) or a 400 MW tower in Namibia could become the tallest structure of any kind if built: 1km and 1.5km tall, respectively. Yet even those are dwarfed by the theoretical super chimney which could stand 5km tall and 1km wide. Such a tower would use the Earth's atmosphere itself as the greenhouse, could cause rain, reduce global warming and generate over 300,000 MW of "green" electricity. [more inside]
The thaw of political ice has freed up data from impressive Russian research projects documenting and analysing the accelerating thaw of real ice. A multi-generational study (Mikhail M. Kozhov, his daughter, her daughter...) of Lake Baikal has unexpectly demonstrated that the lake is warming....At higher latitudes, Sergei Zimov has not just documented the thaw of Siberian permafrost, he is attempting to mitigate it....
CO2 'highest for 650,000 years' Current levels of the greenhouse gases carbon dioxide and methane in the atmosphere are higher now than at any time in the past 650,000 years. (Found via Treehugger) Sounds like it's time to buy that lovely oceanfront property in Kansas.
Alberta will face a disastrous competitive and economic disadvantage if Canada signs the Kyoto accord. Meanwhile, this year has been one of the worst for smog in Toronto. Some municipalities in Ontario are voluntarily looking towards alternate energy sources because they feel, in the long run the costs will be lower (lower health costs, avoiding higher fossil fuel costs, etc. - sorry, no link) What do you think? Is it possible to have economically viable alternative energy, and is the US setting a bad example for countries that feel they need to compete?
