Hank Green: My Advice to the UN: Trash the Kyoto Protocol

The United Nations is meeting this week in Poland, trying to figure out how best to tackle Climate Change. And as they deliberate about how exactly to change their approach to climate change and prepare for the 2009 meeting in Copenhagen, where they will replace the Kyoto Protocol set to expire in 2012 -- all I can say is, Kyoto is done. We need to move on. Now.

Climate Science: Roger Pielke Sr. Research Group News » Are There Long-Term Trends in The Start Of Freeze-Up And Melt Of Arctic Sea Ice?

The finding in this data is that there is no clear evidence of a delay in the start of the later summer/early fall freeze up or the start of the late winter/early spring melt despite the well below average areal sea ice coverage.

A priority in the climate modeling community should be an examination of their predictions of trends in the start of freeze up and start of melt dates, in order to see how they conform to the observational data. Also, the reason that the added atmospheric concentrations of well-mixed greenhouse gases are not changing the dates as expected needs to be provided.
