During the 20 th century, the sea levels rose by 17 cm (6.7 inches); they rose faster in the 2 nd half of this century than in the 1 st. (10)
The sea level rise is consistent with the temperature rise and general warming tendency.
It has been predicted that by the end of the 21 st century the sea level may rise by further 18 to 59 cm (7 to 23 inches), depending on a range of different scenarios. (11)
Loss of snow cover has been another indicator of climate change. Snow cover in the Northern Hemisphere declined by 4% between 1920 and 2005. (12)
As a specific example of this problem, Canada’s eastern Arctic Archipelago decreased by 15% between 1969 and 2004. (13)
The decrease in snow cover has also been consistent with the general warming trend.
What is global warming again ??
Global warming is a very serious issue that affects everyone on the planet.
