    Greenland, Antarctica Melting Six Times Faster Than in the 1990s

    Observations from 11 satellite missions monitoring the Greenland and Antarctic ice sheets have revealed that the regions are losing ice six times faster than they were in the 1990s. If the current melting trend continues, the regions will be on track to match the "worst-case" scenario of the Intergovernmental Panel on Climate Change (IPCC) of an extra 6.7 inches (17 centimeters) of sea level rise by 2100......

    The resulting meltwater boosted global sea levels by 0.7 inches (17.8 millimeters). Together, the melting polar ice sheets are responsible for a third of all sea level rise. Of this total sea level rise, 60% resulted from Greenland's ice loss and 40% resulted from Antarctica's.......

    The IPCC in its Fifth Assessment Report issued in 2014 predicted global sea levels would rise 28 inches (71 centimeters) by 2100. The Ice Sheet Mass Balance Intercomparison Exercise team's studies show that ice loss from Antarctica and Greenland tracks with the IPCC's worst-case scenario........

    A Security Threat Assessment of Global Climate Change

    ......The panel, made up of national security, military and intelligence experts, analyzed the globe through the lens of the U.S. Geographic Combatant Commands, and concluded that:

    “Even at scenarios of low warming, each region of the world will face severe risks to national and global security in the next three decades. Higher levels of warming will pose catastrophic, and likely irreversible, global security risks over the course of the 21st century.”.......

    Key recommendations
    1. Mitigating these risks requires quickly reducing and phasing out global greenhouse gas emissions. We call for the world to achieve net-zero global emissions as soon as possible in a manner that is ambitious, safe, equitable, and well-governed, in order to avoid severe and catastrophic security futures.
    2. The world must also “climate-proof” environments, infrastructure, institutions, and systems on which human security depends, and so we call for rapidly building resilience to current and expected impacts of climate change. With future-oriented investments in adaptation, disaster response, and peacebuilding
    3. In the United States, we call for renewed efforts to prioritize, communicate, and respond to climate security threats, and to integrate these considerations across all security planning.
