On a yearly basis, an estimated 500 million people are
affected by flooding. Due to climate change, flooding
events are increasing in frequency and severity.
In recent years, global disasters have demonstrated the
dangers of relying on single suppliers, single factories, or
single logistics operations.
Iceland’s volcanic ash cloud that swept across
Northern Europe in 2010.
Japan’s nuclear disaster at Fukushima.
The floods in Thailand in 2011.
Question # 5
What changes in the earth’s
crust are happening?
The largest earthquakes happen when 2 plates move towards
each other. Typically when this happens, one plate starts sliding
under the other.
The friction involved in this “subduction” will produce both
earthquakes, such as the tsunami-generating one off Japan in
2011, and volcanoes, the fires of which are fed by the melting of
the deep crust.
There are 7 large plates made up from the earth’s crust:
The African plate.
The Antarctic plate.
The Eurasian plate.
The Indo-Australian plate.
The North American plate.
The Pacific plate.
The South American plate.
Question # 6
What changes are
happening to glaciers?
From 1902 to 2001, the Jakobshavn Glacier near Ilulissat, Greenland retreated
8 miles. From 2000 to 2010, the glacier has retreated more than that.
