Transcript of May you imagine the world in 2050 ?

Greenland glaciers have doubled their rate of flow into the sea in the last few years (6km/year in 1997, 9km/year in 2000, 13km/year in 2003), now raising the sea level by 0.83 mm per year. Similar melting of the West Antarctic ice sheet is adding another 0.55 mm per year, and accelerating.

NEW:
- There are 130 million people living within 1 m of mean sea level.

- In Europe, 13 million would be displaced and 600 billions of $ in property would be lost
Consequences
- The Arctic is shrinking 57 km3 of ice per year

- The ice extent of 1980 was 7 million of km2. In just only 30 years, the Arctic ice cap extension is reduced by more than half, and much of his reduction has also have been in the last decade
Increase of sea level
Consequence of the melt of the poles
The planet does not warm equally everywhere. The temperature change is highest at the poles. Some places may even cool down as ocean currents change heat distribution around the planet.


They will be melted the poles in 2100?
Pablo Gurbindo & David Longás
But, what are the causes of the melting of the poles?
Greenpeace found that the burning of fossil fuels is the main cause of climate change
Solution of
End of the dependence of fossil fuels
Increase of temperature
Melt of the poles
IPCC: Intergovernmental Panel on Climate Change
Demographic consequences
Extinction of species
Polar Bear
Emperor penguin
Walrus
Seal
Conclusion
Kyoto Protocol
Conference of Paris
- The objective of the conference was to conclude a global agreement to reduce emissions of greenhouse gases

- The conference reached his goal achieving for the first time of the history a universal agreement of methods to reduce climate change

- The agreement will be implemented in 2020

- According to the organizing committee, the result is key to limit global warming below 2ºC in 2100
-The polar areas are changing fastest.

-Half of the permafrost in the Arctic is expected to melt by 2050 and 90% before 2100, releasing methane, a powerful greenhouse gas.

- If we continue with our consumerist life style the poles will not be completely melted, but if all the ice of the world were melted the Earth would look like this...
