             The Antarctic continent
• Coldest, driest, windiest, highest, and least accessible
• Winter population 1000 people, 10,000 in summer
• 10,000 tourists visit for a few days in summer
• Ice covered for the last 25 million years
• Less than 1% of continent is ice free
• Once the home of dinosaurs, trees and plants
• An insect is the “lion” of the Antarctic
               The Southern Ocean
• Fifty million seals & 15 million penguins
• Regional fishery of global economic value
• History of over-exploitation. Seals, whales. penguins
  and fish
• Fishery for krill and fish regulated by science-backed
  international body under Antarctic Treaty
• Pirate fishing due to lack of effective policing
• Decline of albatross due to mortality on long lines of tuna
  fishermen in sub-Tropics
              The Antarctic Treaty
• Antarctica is “a natural reserve devoted to peace and
• The Antarctic Treaty manages the region’s wildlife
• Mining is forbidden
• The Treaty runs indefinitely
• Forty-four countries have acceded to the Antarctic Treaty
  (80% of the world population)
• All 44 countries have to agree to Treaty revisions
    “Green” fallacies about the Antarctic
• The Antarctic Treaty expires in 50 years
• Mining is only banned for 50 years
• Antarctica is under threat from developers
• People working in the Antarctic have polluted the
• Antarctica still has to be saved
• Penguins fall over backwards when planes fly overhead!
       Home truths from the Antarctic
• The Antarctic is the most rigorously protected region of
  the world
• The protection is legally backed
• International inspection teams monitor compliance with
  the Antarctic Treaty
• Man’s footprint on Antarctica is practically invisible
• More “pollution” enters the region through the
  atmosphere than is generated there (DDT, CFCs )
              Antarctic discoveries
• The destruction of the ozone layer
• A 400,000 year demonstration of the link between
  greenhouse gases and climate
• The global impact of the Industrial Revolution
• A reduction of the height of the ionosphere consistent
  with “global warming”
• Lakes beneath the Antarctic ice sheet believed to contain
  life forms possibly millions of years old
        Antarctica is part of the world
• The Earth system involves the whole Earth
• Antarctic studies are essential
• There can be no weak link in understanding the Earth
• Climate feedbacks involving ice, snow, sea ice and ocean
  currents provide the greatest challenges in predicting the
                      The Arctic
• Contains cities, towns and universities
• Indigenous population share the region with new settlers
• All Arctic land is under the jurisdiction of a sovereign
• UK scientists regularly work in the Arctic
• There is far more science activity in the Arctic compared
  to the Antarctic
             The Antarctic ice sheet
• Ice up to three miles (4500 m) thick
• Coldest surface temperature -89 degrees C
• Enough ice for each person in the world to have a block
  180 m by 180 m by 180 m
• If all melted, sea level could rise 65 metres
• If all the glaciers doubled their speed of flow it would
  take 12,000 years for the ice to float into the Southern
           Antarctic ice and sea level rise
• A small change in the size of the      • The disintegration of ice shelves

     Future developments in Antarctica
• Exploring the largest lake under the ice sheet
• Obtaining a reliable climate record over half a million
• Exploiting natural “antifreeze” in Antarctic organisms
• Studying the effects of increased UV-radiation and
  “global warming” on Antarctic life
• Celebrating the centenaries of the historic expeditions of
  Scott, Shackleton and Bruce
