Sea levels around the world are rising because of climate change, as warming ocean waters and melting ice cause the oceans to encroach on the world's coasts.

Coastal ecosystems, formed by plants that can thrive in saltwater, are especially good at storing carbon because of the thick, rich layers of soil they build up.

Hurricanes are intense tropical cyclones. These storms are becoming stronger as climate change warms the oceans.

Freight transportation moves billions of tons of cargo around the world each year. Nearly all freight transportation runs on oil and gas.
