Climate Long term weather patterns www.blueplanetbiomes.org Factors Affecting Climate Altitude www.cappadocia.travel Latitude www.mrdowling.com Currents go-passport.grolier.com Altitude How far above sea level you are The farther up, the cooler the climate is. With climate change, people are moving farther up mountains to avoid mosquitoes.How does this impact other organisms? news.bbc.co.uk/2/low/science/nature/5348692.stm Latitude How far north or south of the equator you are. Equator receives direct sun rays. The farther from the equator the greater the angle of incidence of light, thus the cooler the climate schools-wikipedia.org/wp/e/Effect_of_sun_angl... Currents Wind Currents Ocean Currents Wind Currents Air moving across the warm waters of the North Atlantic moderate the Climate of Northern America and Western Europe Wind Currents The Jet Stream moves south of us during the winter, pulling cold Artic air from the NW into Michigan. Fast moving systems from the Canadian Rockies are called Clippers. www.jeffsweather.com www.accuweather.com Wind Currents During the summer, the Jet Stream moves to the north of Michigan. Air from the Gulf of Mexico travels from the SW to bring moisture and warmth to Michigan www.fas.org/.../docs/rst/Sect14/Sect14_1c.html Wind Currents Test Yourself.

Atlantic pick up the heat and transfer it to W. Europe and N. America thedifferencemagazine.blogspot.com/2007/08/no... Ocean Currents Glacial melt at the poles creates cold dense water that sinks and travels to the equator. This drives the warm less dense water to the surface and pushes it northward nsidc.org/.../factors/land_sea_distribution.html Ocean Currents What is the future of the N. Atlantic Current if there is no glacial melt? What becomes of the Climate in the Northern Hemisphere? Earths Climatic History 1.6 mya Earth’s Climate is like a pendulum. It naturally swings between extreme heat and cold over long periods of time.

The most likely cause is a disruption in the N. Atlantic current. These have been natural occurring events over Earth’s history. Greenhouse Earth Effect CO2 is rising faster than at any period in recent history. Will man cause the next climate change before its time? If so what is the effect on Michigan? www.webwombat.com.au
