1. Impacts of Climate Change – sea levels WORLD AT RISK

2. What is the connection?

3. What’s happening to Greenland? ‘If you’re a fisherman in Greenland global warming is doing wonders for your business because the harbour no longer freezes over’‘If you’re a fisherman in Greenland global warming is doing wonders for your business because the harbour no longer freezes over’ Economic boost through tourism for the 56,000 Inuit inhabitantsEconomic boost through tourism for the 56,000 Inuit inhabitants Air Greenland started their first direct flights from Baltimore to attract American touristsAir Greenland started their first direct flights from Baltimore to attract American tourists So what is all the fuss about?

4. What’s happening to Greenland? Since 1992 glaciologist have reported:Since 1992 glaciologist have reported: 5°C increase in winter temperatures5°C increase in winter temperatures 3°C spring and autumn temperatures3°C spring and autumn temperatures Increased speeds of ice meltIncreased speeds of ice melt Increased speeds of glacier movement towards the oceansIncreased speeds of glacier movement towards the oceans Glaciers retreating up to 10kmGlaciers retreating up to 10km

6. Greenland Ice Sheet Global sea level would rise 7m (23ft) this is called eustatic sea level changeGlobal sea level would rise 7m (23ft) this is called eustatic sea level change Thermal expansion is also leading to a rise in sea levels Thermal expansion is also leading to a rise in sea levels On your A3 hand-out I would like you to highlight/annotate the global impacts that a rise in sea level would have.On your A3 hand-out I would like you to highlight/annotate the global impacts that a rise in sea level would have. http://flood.firetree.net/http://flood.firetree.net/http://flood.firetree.net/

7. Greenland ice sheet I would like you to write downI would like you to write down What is happening in Greenland as a result of global warmingWhat is happening in Greenland as a result of global warming Why is this such a big issueWhy is this such a big issue What impact this will have on global sea levelsWhat impact this will have on global sea levels

8. Ocean circulation Thermohaline Warmer waters near the equator Water move towards the poles Water cools and freezes As water freezes it leaves behind the salt meaning water become more saline Colder, denser more saline water sinks

9. Thermohaline circulation

10. Impacts of global warming Warmer waters near the equator Water move towards the poles Ice sheets are melting meaning there is more freshwater Water is not sinking so no longer pulling warmer waters pole ward

11. Impacts of Global warming

12. Impacts of global warming Warmer waters near the equator Water move towards the poles Ice sheets are melting meaning there is more freshwater Increased river runoff (glacial melt water)

13. Ocean circulation I would like you toI would like you to Explain why ocean circulation currents such as thermohaline circulation is importantExplain why ocean circulation currents such as thermohaline circulation is important What impacts will global warming have on thisWhat impacts will global warming have on this
