The report finds it's more certain than before that humans are the cause for increased temperatures world wide.
The authors wrote climate change is close to creating a severe impact on us, that if not fixed in a few decades, we will not be able to reverse.
It offered solutions, including reducing emissions from fossil fuels, like oil and coal.
