Climate Changes Due To Global Warming: A Global Issue

The Main Culprits For Global Warming

Water Vapour (H2O)Carbon Dioxide (CO2)

Methane (CH4) Ozone (O3)

Some Facts

• Human population x 4 in 100 years• It took 10000 generations of human beings to

reach 2 B• We have tripled that in less that one lifetime

Temperature goes up melting ice caps

• Before the warming: Kilimanjaro, 1970

• After the warming: Kilimanjaro, 2000

Temperature goes up melting ice caps

• Before the warming: Nepal, 1978

• After the warming: Nepal, 2004

Temperature goes up melting ice caps

• Even more obvious from space, this pictures of the North Polar cap from NASA show a melting of 25% in 25 years:

Graphical Data

• At the end of 2002, the concentration of carbon dioxide was just above 370ppm.

• This is probably the highest in at least 400,000 years

Graphical Data- Carbon Footprint

• Every country bears its share of responsibility, The USA being number one.

Some Facts:-

• The number of category 4 and 5 hurricanes has almost doubled in the last 30 years.

• Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level.

• The flow of ice from glaciers in Greenland has more than doubled over the past decade.

• At least 279 species of plants and animals are already responding to global warming, moving closer to the poles.

The Consequences of sticking to ‘Business As Usual”

• Global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide.

• The arctic ocean could be ice free in summer by 2050.

• Heat waves will be more frequent and more intense.

• Droughts and wildfires will occur more often.
