Well, climate change occurs when changes in Earth's climate system result in new weather patterns that remain in place for an extended period of time.
What's climate change?
It's the greenhouse effect and human activities that have contributed to climate change by adding carbon dioxide and other heat-trapping gases to the atmosphere.
So, human activities, such as the burning of fossil fuels and changes in land use, release large amounts of CO2, causing concentrations in the atmosphere to rise.
But why is this happening?
The planet's average surface temperature has risen about 1.62 degrees Fahrenheit since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.
Earth’s climate is changing very quickly and global climate change has already resulted in a wide range of impacts.
Greenhouse gas emissions have increased the greenhouse effect and caused Earth’s surface temperature to rise. The primary human activity affecting the amount and rate of climate change is greenhouse gas emissions from the burning of fossil fuels.
