What is Global Warming?

What is Global Warming?

Global warming is the increase of the Earth’s average surface temperature due to a build up of green house gases in the atmosphere.

Carbon dioxide is the most common gas that causes global warming.

As temperatures increase, the climate changes.

Greenhouse EffectGreenhouse Effect Sunlight enters the earth’s atmosphere and most of the light is reflected back by the earth’s surface.

Greenhouse gases act as a shield trapping the sun’s energy and preventing it from leaving our atmosphere.

The trapped sunlight causes the earth temperatures to rise and change our climate and weather.

Twice in the past ten years, we’ve had the hottest temperatures ever recorded in the planet’s history.

Deforestation is responsible for 20-25% of all carbon emissions entering the atmosphere

Burning of fossil fuels

Temperatures of waters rise, so it is hard for fish to adapt this change.

As the earth warms, plants will have to migrate at a rate of 1.6 km per year which is 5 times higher than normal migration rate.

Polar bears are drowning because they are unable to swim the longer distances between land and the receding ice.
