Climate Change over millions of Years.

Tropical seas once covered the Arctic and Climate Change has gone through many changes over the last 400 million years. Fishes that swam in these hot waters, back in those days, now tell scientists about the environmnet and its changes over the ages, as shown through the Fossil Record.

Severe Weather Study

Thunderstorms, tornadoes and other severe weather is being studied under a project called UN-STABLE (understanding Severe Thunderstorms and Alberta Boundary Layers Experiment). It aims at better understanding thunderstorm initiation, which it hopes will improve weather forecasting.
Good Luck

Violent 2008 Summer Weather

Forecasters predict that this summer of 2008 will be hot and dry on the Canadian Prairies and the USA northern States.
This means that the Jet stream is moving further north and Tornado Alley will also move northward from its normal Mid-western position. Tornadoes have already touched down in southern Manitoba.

Arctic Warming

The Arctic is warming at a rate that is three times that of the rest of the world according to Bartley Kives writing in the Winnipeg Free Press after he spent two weeks aboard the ice-breaker Amundsen. He was among scientists trying to learn more about the air, water, ice, plants and animals in the Arctic region. They estimate that completely ice-free Arctic waters are coming to this planet by 2013 to 2030.

Icebergs

Icebergs in the Antarctic area sometimes have stripes,�formed by�layers of snow�that react to different conditions.Blue stripes are often created when a crevice in the ice sheet�fills�up with meltwater�and freezes so quickly that no�bubbles form.When an iceberg falls into the sea, a layer of salty seawater�can�freeze�to the underside. If this is rich in algae,�it can form a green�stripe.Brown, black and yellow lines are caused by sediment,�picked up when�the ice sheet grinds downhill�towards the sea

Wind Power

Wind is air in motion. This invisible force can be powerful and destructive; but it can also be harnessed to generate clean electric power. Wind turbines with long propeller blades, erected in clusters, or wind farms, can be used to replace coal and oil fired plants that are belching pollution into the atmosphere. Farmers living near these turbines are voicing concerns about noise and hazards to birds and planes. In Manitoba the wind farms are being built one kilometer away from residences, so that noise and vision obstructions will be negligible.

Slowing the Warming

Warming of the atmosphere could be slowed down…but it would be expensive and it could have side affects.
The process would involve sending reflective material into the atmosphere, such as sulphur or aerosols that would send the sun’s radiation back into space.
This happened when Mount Pinatubo erupted in 1991. Millions of tons of sulphur dioxide were sent into the air.
Earth’s temperature dropped by 0.25 degrees Celsius.
