Frequently asked questions

What is the difference between climate change and global warming?

Global warming names one effect: the rise in average global temperature. Climate change is the broader term, covering that warming plus the shifts it drives — altered rainfall, stronger storms, rising seas, ocean acidification. Warming is the cause; climate change is the whole picture.

What is the difference between weather and climate?

Weather is what happens over hours or days in one place; climate is the pattern averaged over decades across a region. A cold week does not contradict a warming climate, in the same way one tall child does not change a school's average height.

Is climate change caused by humans?

The overwhelming scientific consensus is that the warming observed since the mid-twentieth century is predominantly caused by human greenhouse gas emissions. Natural climate change has occurred throughout Earth's history, but it does not account for the current rate or pattern of warming.

What is the meaning of climate change?

"climate change" (noun) means the long-term shift in global temperatures and weather patterns driven mainly by human emissions of greenhouse gases from burning fossil fuels, deforestation and agriculture, producing warming, sea-level rise and more frequent extreme weather.
