Evidencefor


 * Green house gas**
 * 1) Carbon dioxide **increasing in atmosphere** from pre-industrial 280 ppm to 377.5 ppm (34% increase--highest in 650,000--caused by the **burning of fossil fuels**—gasoline in a car or coal burning in a power plant
 * 2) methane gas increase (also caused by the burning of fossil fuels) increased by 145%

The recent increases of them have been drastic- much more severe then in decades previous = **Warming the Planet** =**Droughts**
 * 1) **Melting of Polar Ice Caps**(Global Warming's "Canary in the Coal Mine")--highly sensitive region that is experiences **drastic changes due to increase in temperature**--foreshadower of things to come--average temperatures are rising twice as fast as everywhere else--arctic ice is getting thinners, melting and rupturing
 * 2) satellite images of the ice caps have shown ice coverage to decrease by 9% each decade--rate of melting has increased by 300% in the past 20 years on 6 continents
 * 3) When ice over land melts it leads to runoff and flooding.
 * 4) this will mean that with **less ice coverage**, the **earth’s temperature will increase** due to the sun directly hitting the earth’s water, causing them to warm
 * = Warming & Rising Ocean Levels**
 * 1) species from Plankton to Whales are moving North to escape the warming waters off of Greenland and Alaska
 * 2) Ice Caps melting=rise in ocean level and temperatures--change the ecology of the ocean entirely--many species will not be able to adapt
 * 3) evidence of warming supported by seaborne highly accurate computar technology
 * 4) warmer oceans mean harsher storms- hurricanes get strength with warmer waters

Severer droughts are occurring- Lake Chad has dried up, causing conflict. [[[|http://www.ecobridge.org/content/g_evd.htm|]http://www.ecobridge.org/content/g_evd.htm|]]
