Drought
Regions near desert it is worst
Inadeute food source
Wildfires
Very dry , they lose leaves
Canadian wildland Fire information system spreads news publishes fire weather and fire behaviour maps
Storms
Effect of rapid increase in average global temperature and movement of energy
Flood
When spring comes to quickly
Hydrosphere effects
Melting ice
Ocean warming
Ocean currents
Melting ice
Northwest passage Causing loss of property Changing habitats of hairline plants animals and micro organisms Flooding land that is above sea level Changing geographical coastlines Reducing amount of fresh water available
Ocean increase
20%
Water expands as warms
Glaciers on land retreat
Greenland and Antarctica glaciers melting
Ocean warming
Water eas water increases
Warm water absorbs less carbon dioxide less effective carbon sink
Not ideal for plankton growth
More intense hurricanes
Ocean currents
Salinity increases
Wind does currents in top
Deep currents pushed by dense salty water
Birth altlantic deep water current could slow down to about half its speed disrupting the global ocean current system
Effects on wildlife
Range shifts
Threatened species
Range shifts
Species move farther north to find ideal place Grey jays Dan Strickland study Hard food for winter Moved northward Opossums and ticks have moved Wildflowers bloom 26 days earlier o
Threatened sketches
40-70 percent of all species risk of extinction if 3.3 degrees more
2008 international union for the conservation of nature began to identify species
Coral secrete skeleatlns related to jellyfish
Oceans resolve more carbon dioxide more acidic kill most coral reefs
Species that benefit
Jellyfish
