The Antarctic ice sheet is melting, and some of the damage is irreversible! Over the next 200 years, the ocean is expected to rise 10 feet, putting many major cities worldwide underwater! Laci reports on this news, and discusses why immediate action is necessary.

Tidally adjusted estimates of topographic vulnerability to sea level rise and flooding for the contiguous United States sealevel.climatecentral.org/research/papers/tidally-adjusted-estimates-of-topographic-vulnerability-to-sea-level-rise-a/ "Because sea level could rise 1 m or more during the next century, it is important to understand what land, communities and assets may be most at risk from increased flooding and eventual submersion." Sea Level Rise: The Risk, The Facts www.globalgreen.org/articles/global/95 "Among other challenges, climate change is causing our sea levels to rise and putting our coastal cities -- and billions of people -- at risk across the globe." As West Antarctica melts, the urgency for climate change adaption rises thebridge.agu.org/2014/05/12/west-antarctica-melts-urgency-climate-change-adaptation-rises/ "As if the recent reports from the Intergovernmental Panel on Climate Change (IPCC) and the National Climate Assessment (NCA) weren't enough of a reminder of the ways in which human actions are changing our planet, new research published in the current edition of Geophysical Research Letters (GRL) presents evidence that part of the West Antarctic Ice Sheet has passed a tipping point."
