A presentation of 12 slides on Global Warming by Arjit Saraswat.

1. 1 STOP!

4. If we did not have the greenhouse effect this world would be about 30 degrees Celsius colder.

6. Some natural causes include solar activity, volcanic emissions, changes in earths orbit and natural greenhouse gasses.

7. Human causes mostly include burning fossil fuels and exerting harmful gasses into the atmosphere.

9. 6 Temperatures Between the years 1860-1900 average temperatures have increased by 0.75 degrees Celsius. Over the past 100 years global temperatures have risen by 1.3 degrees.

10. 7 Weather in recent winters Recent winter was the warmest winter ever recorded( in the history of the planet Earth). 10 out of the past 14 years are the warmest on record.

11. 8 Glacier and Ice Cap Melting Evidence of global warming is very apparent in the recent melting of ice sheets. Two places where melting has become extremely visible are Antarctica and Greenland. One problem with this is that much less heat is absorbed by snow than by water, thus worsening the effect as the ice retreats. left- predicted arctic melting

13. A direct consequence from our polluting actions will be the disappearance of these vital glaciers.

15. Two years ago the entire Larsen B ice shelf broke away into pieces in less than a month. Scientists thought it would be at least a decade before this shelf melted, even with global warming.

16. Both Greenland and Western Antarctica are depleting at shocking rates.
