Evidence of Climate Change Climate Change Climate Change

Rising Temperatures avg temp in Canada inc by 1 o C in past 55 yrs (2.5 o C in Arctic) avg temp in Canada inc by 1 o C in past 55 yrs (2.5 o C in Arctic)

Melting Glaciers, Ice Sheets & Sea Ice ½ of world’s population depend on Glaciers for fresh water (China & India) ice shelves in Greenland and Antarctica breaking off – rising sea levels and increasing fresh water in oceans (can affect ocean currents) Arctic could be ice-free in summer in a few years (reflect less sun)

Changes in Severe Weather hurricanes/typhoons stronger and more frequent due to warmer ocean temp hurricanes/typhoons stronger and more frequent due to warmer ocean temp more warm air rises creating pressure differences more warm air rises creating pressure differences Changes in Precipitation Patterns northern hemi. getting more rain less snow northern hemi. getting more rain less snow areas near equator becoming drier areas near equator becoming drier
