LATEST EVIDENCE. Antarctica’s Thwaites Glacier Ice Shelf Begins To Break Up (Ian Joughin, a glaciologist at the University of Washington in Seattle). Planet Earth may be at greater risk than ever before if global climate change proves to be a long-term threat. Two teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries-long, "unstoppable" process that could raise sea levels by as much as 4 m (15 ft). The glacier serves as a linchpin for the rest of the West Antarctic Ice sheet, which has enough frozen mass to cause another 10 to 13 feet (3 to 4 meters) of sea level rise. Many locations will have environments at higher risk as temperature increases and sea level rises, as hypothesized. Presentation courtesy of Dr. Walter Haye, Global Alliance for Disaster Reduction

Scientific Evidence Points To Earth's Greater Fragility

  3. 3. WEST ANTARCTICA:THWAITES ICE SHELF IS BREAKING UP
  4. 4. THWAITES GLACIER • Thwaites Glacier is losing several meters (tens of feet) of ice elevation every year.
  5. 5. WARNING Planet Earth may be at greater risk than ever before if global climate change proves to be a long-term threat
  6. 6. Source: SCIENCE, May 2014 • Two teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries-long, "unstoppable" process that could raise sea levels by as much as 4 m (15 ft).
  7. 7. Source: SCIENCE, May 2014 • They estimate that Thwaites Glacier will probably disappear entirely in somewhere between 200 and 1,000 years. • That loss alone would raise global sea level by nearly 2 feet (60 centimeters).
  8. 8. Source: SCIENCE, May 2014 • The glacier serves as a linchpin for the rest of the West Antarctic Ice sheet, which has enough frozen mass to cause another 10 to 13 feet (3 to 4 meters) of sea level rise.
  9. 9. IF PLANET EARTH CONTINUES WARMING UP, - - - MANY LOCATIONS WILL HAVE ENVIRONMENTS AT HIGHER RISK AS TEMPERATURE INCREASES AND SEA LEVEL RISES, AS HYPOTHESIZED
