EVIDENCE OF PLANET EARTH’S FRAGILITY May 12, 2014 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA

LATEST EVIDENCE May 12, 2014 ANTARCTICA’S THWAITES GLACIER ICE SHELF BEGINS TO BREAK UP Ian Joughin, a glaciologist at the University of Washington in Seattle
3
WEST ANTARCTICA:THWAITES ICE SHELF IS BREAKING UP
4
THWAITES GLACIER Thwaites Glacier is losing several meters (tens of feet) of ice elevation every year.
5
WARNING Planet Earth may be at greater risk than ever before if global climate change proves to be a long-term threat
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
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
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
IF PLANET EARTH CONTINUES WARMING UP, - - - MANY LOCATIONS WILL HAVE ENVIRONMENTS AT HIGHER RISK AS TEMPERATURE INCREASES AND SEA LEVEL RISES, AS HYPOTHESIZED
10
CITIES (PEOPLE, PROPERTY, AND INFRA- STRUCTURE) MAY BE AT HIGHER RISK
11
IMPACT: NORTHEAST USA: 1 METER RISE IN SEA LEVEL
12
IMPACT:FLORIDA: 1 METER RISE IN SEA LEVEL
13
IMPACT: LOUISIANA: 1 METER RISE IN SEA LEVEL
14
MONITORING, MITIGATION, AND ADAPTATION MEASURES: WAYS TO COPE WITH GLOBAL CLIMATE CHANGE
15
CURRENT NEEDS Planet Earth’s changes in exposure and risk over time have created a need for: Technology to monitor global climate change, warn people, and protect property, and infrastructure.
