Consequences of Global Warming Global Climate Change

Global Warming Vs. Global Climate ChangeGlobal warming refers to the rising of Earth’s surface

temperature.

Global climate change refers to warming and the “side-effects” of warming.

Current Concerns: Sea Level is Rising

Land Ice Melting! Thermal Expansion!

Sea Level: Environmental Implications

Saltwater introduced into freshwater habitats, like coastal wetlands.

Saltwater will contaminate freshwater aquifers.Flooding will damage habitats.

Sea Level: Economic Implications

Tourism will decline as recreational areas are flooded.

Flooding and Relocation of Communities

It’s Already Happening!

Home to the Biloxi-Chitimacha-Choctaw and the United Houma Nation Tribes

Since 1955, the island has lost 98% of its land.

Climate Models

Average temperature increase of 1.8 to 4°C

by 2100

Future Concerns: The Oceans• People are concerned with the changes that might

occur if things continue to get warmer. • More intense/more frequent hurricanes. • Ocean acidification and Coral Bleaching • Vertical mixing and thermohaline circulation may be

affected.
