What is global warming?

The changes in the surface air temperature, referred to as the global temperature, brought about by the enhanced greenhouse effect, which is induced by emissions of greenhouse gases into the air.

The Sun’s energy passes through the car’s windshield.

This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.

Example of the Greenhouse Effect

What’s the difference between “global warming” and “climate change”?

GLOBAL WARMINGCLIMATE CHANGE

Is the increase of the Earth’s average surface

temperature due to a build-up of greenhouse

gases in the atmosphere.

Is a broader term that refers to long-term changes in climate, including average temperature and

precipitation.

Simple Things To Do

Turn off your computer or the TV when you’re not using it.

Take shorter showers. Heating water uses energy.

Keep rooms cool by closing the blinds,

shades, or curtains.

Turn off the lights when you leave a room.

Use compact fluorescent bulbs.

Simple Things To Do

Dress lightly when it’s hot instead of turning up

the air conditioning. Or use a fan.

Dress warmly when it’s cold instead of turning up the heat.

Offer to help your parents keep the air

filters on your AC and furnace clean.

Walk short distances instead of asking for a ride in the car.

Plant a tree.

Recycle.

Facts and Predictions

from the IPCC

The fourth Human activity

is heating up the planet. Various scenarios show where global

warming could take us by the

end of the century.
