The Third U.S. National Climate Assessment was released by the White House today. It provides an overview of the effects of climate change on a range of issues from agriculture and the oceans to human health and infrastructure. In a related note, the prominent climate scientist Michael Mann published an op-ed today in The Guardian today, reporting that Keystone XL pipeline project will likely fail to pass in the U.S. Senate based on the current estimate of votes. This should be a major victory for those who have opposed the pipeline project since its inception, especially Bill McKibben and 350.org. This could also represent a major turning point in U.S. politics with regards to climate change.
