RT null T1 Global Outlook for Ice and Snow - Chapter 9 A1 United Nations Environment Programme, A2 Eamer, Joan A2 Lambrechts, Christian A2 Prestrud, Pål A2 Young, Oran K1 ice PB United Nations Environment Programme SN 978-92-807-2799-9 YR 2007 FD 2007 LK https://wedocs.unep.org/handle/20.500.11822/14468 UL https://wedocs.unep.org/handle/20.500.11822/14468 NO The underlying theme in the preceding chapters is that changes are now observed in ice and snow and bigger changes are projected. The greenhouse gases from past and current emissions remain in the Earth’s atmosphere for decades to centuries. Most of the extra heat on Earth caused by emissions of anthropogenic greenhouse gases is stored in the oceans. These two factors will lead to further changes in ice and snow no matter how quickly the world acts to reduce emissions.
