The landmark National Climate Assessment report was written by 300 experts, guided by a 60-member Federal Advisory Committee, and reviewed by a panel of the National Academy of Sciences. It documents climate changes, makes future projections, and analyses impacts nationally and regionally on seven sectors – human health, water, energy, transportation, agriculture, forests, and ecosystems. The report is available in a variety of formats – go to http://nca2014.globalchange.gov/highlights. On May 14th, the U.S. Center for Naval Analyses and its Military Advisory Board (composed of 16 retired generals and admirals) released a “bipartisan call to action” in the form of its report: National Security and the Accelerating Risks of Climate Change at: http://www.cna.org/sites/default/files/MAB_2014.pdf. The report argues that climate-related events such as flooding, drought and rising sea levels bring population dislocation and food insecurity, and therefore act as “catalysts for instability and conflict”. Importantly for Canadians, they warn that an ice-free Arctic will bring competition for shipping lanes and access to undersea oil deposits – see an article in The Guardian at: http://www.theguardian.com/environment/2014/may/14/climate-change-arctic-security-threat-report?CMP=EMCENVEML1631.
