Climate Change - Rising Sea Levels

There is enough water stored in the East Antarctic ice sheet to raise sea levels by 164 feet (50 meters).

CLIMATE CHANGEEffects on sea level

Climate change is a change in global weather patterns because of human actions, such as polluting the atmosphere or burning fossil fuels.

What is climate change?

When sea levels rise rapidly, it has devastating effects on coastal habitats. As seawater reaches farther inland, it can cause destructive erosion, flooding of wetlands, contamination of aquifers and agricultural soils, and lost habitat for fish, birds, and plants.

At the current rate the sea is rising, by 2100, it would of risen but 2 -7 inches.

Why are sea levels rising?

Consequences

As air temperatures rise (due to climate change) the water in the oceans is warmed and expands. This process is called thermal expansion.

As ice sheets and glaciers melt, they increase the amount of water in the oceans.

Glaciers and Polar Ice Caps

Large ice formations, like glaciers and the polar ice caps, naturally melt back a bit each summer.

Recently, though, persistently higher temperatures caused by global warming have led to greater-than-average summer melting This results in a significant gain in runoff causing sea levels to rise.

WHAT YOU CAN DO TO HELP STOP CLIMATE CHANGE

-be energy efficient-choose renewable power-reduce carbon footprint-eat locally grown food
