WASHINGTON – The cost of fighting climate change will only climb if industrialized nations don’t take steps to reduce greenhouse gas emissions, according to the United Nations.

In its report, the Intergovernmental Panel on Climate Change said it’s more certain than before that the planet is warming and humans are to blame.

The group says climate change is close to creating “severe, pervasive and irreversible impacts for people and ecosystems.”

They said countries should focus on reducing carbon-based emissions from fossil fuels.

Previous rounds of talks have been strained by disputes between the biggest emitters, including China, the United States and European countries, and poorer countries whose populations could see the worst impacts first.
