CLIMATE CHANGE

1. CLIMATE CHANGE By: VineeshaSrivastava IX-C D.A.V PUBLIC SCHOOL, NEWPANVEL

2. WHAT IS CLIMATE CHANGE? Changes in : • Sun’s orbit • Earth’s orbit • Drifting continents • Volcanic eruptions • Green house gases

3. WHAT ARE THE CONSEQUENSES OF THESE CHANGES? • natural disasters • hotter summers • unseasonal rainfall • economic losses • loss of life and wellbeing or health • Global warming • loss of biodiversity • spread of infectious diseases

5. LET’S SEE SOME EXAMPLES

6. Starving Children in Nigeria

7. Due to climate, drought, poor agricultural planning, political instability, and ineffectiveness and the mismanagement of natural resources, there are millions of starving people throughout the world.

8. It is estimated that each year between 5 and 20 million people die of starvation, many of them, like those in the photo, are children.

9. Fish River Canyon, Namibia

10. This photograph gives some idea of the power of water and the damage it can do, even in an arid climate such as that of Namibia in southwest Africa. The Fish River is barely a stream for much of the year, and in parts dries up completely.

11. But when it arrives, the short wet season brings torrential rains which run off the rock-hard soils and, within a matter of a few hours, swell the Fish into a raging torrent capable of gouging out a deep canyon such as this.

12. Flooded Cologne

14. In January and February 1994, the German city of Cologne was flooded when the Rhine burst its banks after an exceptional buildup of extra runoff in its mountain headwaters.

15. Described at the time as the “flood of the century”, similar scenes were repeated along the Rhine only a year later.

16. Hubbard Glacier

17. In Alaska many alpine, or valley, glaciers flow down mountainous valleys to the sea. Here, for example, the Hubbard Glacier enters Glacier Bay near Yakutat, Alaska.

18. Icebergs form when pieces break off the snout of the glacier and float around in the sea. This is called calving and is the primary process by which glacial ice is recycled into liquid form.

19. Alaskan Earthquake

20. The Alaskan earthquake of 1964 was rated 9.2 on the Richter scale. One of the most powerful earthquakes ever known to hit North America, it claimed 131 lives and devastated parts of Anchorage and Valdez.

21. The quake destroyed foundations and left gaping cracks in the cement of this street.

22. Smoke Billowing from Industrial Smokestacks

23. Carbon dioxide, sulphur dioxide, and other types of contaminants pouring from industrial smokestacks contribute to worldwide atmospheric pollution. Carbon dioxide contributes significantly to global warming, while sulphur dioxide is the principal cause of acid rain in eastern and northern Europe and northeastern North America.

24. Other environmental problems stemming from smokestack emissions include respiratory diseases, poisoned lakes and streams, and damaged forests and crops.
