Kudos to Environment Minister Peter Kent for giving Canadians a climate scare-free Earth Day | Frontier Centre

Hopefully Kent’s real-world, science-based approach to this year’s Earth Day is an indication of the beginning of a shift in the Government’s focus away from futile climate control plans to real environmental protection that we can actually accomplish. The approach certainly worked on Earth Day 2013 where, aside from the predictable attacks from climate activists, most coverage of the Government’s announcement was positive.

Bravo, Minister Kent.

Mark Zuckerberg's New Political Group Spending Big On Ads Supporting Keystone XL And Oil Drilling | ThinkProgress

Mark Zuckerberg’s new political group, which bills itself as a bipartisan entity dedicated to passing immigration reform, has spent considerable resources on ads advocating a host of anti-environmental causes — including driling in the Arctic National Wildlife Refuge (ANWR) and constructing the Keystone XL tar sands pipeline.

There is clearly a discrepancy between the paleo and other estimates, with the paleo estimates spanning much wider ranges - these studies are very badly constrained indeed. It seems to me that the best way to deal with this is to recognise that the range of overlap is the area that can explains both sets of results and that this should be treated as the best estimate of ECS. On that basis it's hard to justify a range that spans much more than 1-3°C.
