Global Temperature Increase

The average air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century.
As Earth warms, NASA observed that sea levels are rising
Melting ice from glaciers and ice sheets flows into the ocean.

Ocean Acidification

Ocean acidification is a phenomenon that can be harmful for marine life
As warm water gets warmer, it takes up more room in the oceans.

Climate Change Data

Climate change describes a change in the typical weather for a region, such as high and low temperatures and amount of rainfall, over a long period of time.
Scientists have observed that, overall, Earth is warming.
The rise in global temperature is sometimes called global warming.

Greenhouse effect

Some of the gases in Earth’s atmosphere trap heat from the Sun, like the glass roof and walls of a greenhouse
Human activities, such as the destruction of forests and burning fossil fuels, create extra greenhouse gases.
When we burn fossil fuels, the carbon that was in the ground goes into the air as a gas called carbon dioxide
Plants and trees can absorb some of this extra carbon dioxide, but a lot of it stays in the atmosphere as a greenhouse gas.
Over millions of years, Earth's climate has warmed up and cooled down many times, often influenced by the sun’s activity.

Test your knowledge on the differences between climate and weather, the mechanisms of climate change, and the evidence supporting global warming. This quiz covers essential concepts such as the greenhouse effect and human contributions to climate change. Prepare to learn more about one of the most pressing issues of our time!
