The Greenhouse Effect
The greenhouse effect is a natural warming process.

Some sunlight that hits the earth is reflected. Some is trapped by greenhouse gases in the atmosphere and becomes heat.

The amount of greenhouse gases in the atmosphere is increasing rapidly, causing the Earth's temperature to rise quickly.

Sources of GHGs in the US by Human Activity
CO₂: Electricity 35%
CO₂: Transportation 27%
CO₂, N₂O: Industry 20%
N₂O, CH₄: Agriculture 7%
CO₂: Commercial 6%
CO₂: Residential 5%

…Causing Sea Levels to Rise
Expected global sea-level rise by 2100: more than 2 feet

As seawater heats up, it expands, raising sea level.
