Why does climate change matter?

In Climate change

Climate change is one of the most pervasive and threatening issues of our time, with far-reaching impacts in the twenty-first century.

Climate change is expected to have unprecedented implications on where people can settle, grow food, build cities, and rely on functioning ecosystems for the services they provide. In many places, temperature changes and sea-level rise are already putting ecosystems under stress and affecting human well-being.

Our work on climate change cuts across the fields of science, policy, technology and finance. We help countries pursue low-emission development and boost their capacity to adapt and be resilient to climate change. We empower countries to seize new investment opportunities that reduce greenhouse gas emissions from deforestation and forest degradation. And we support the development of new finance models to accelerate the transition to a green economy.

We are also working to implement the Paris Agreement, the world’s roadmap for tackling climate change. Our contributions include bringing science to policymakers, playing a leading role in transformative global partnerships, and helping dozens of countries develop national plans to cut greenhouse gas emissions.
