Our climate is changing

Observed CO2 emissions, temperature and sea levels are rising faster than expected.

Human activities are changing the climate

Greenhouse gas emissions from human activities are 90% likely to have caused most of the global warming since the mid-20th century.

Climate change science and solutions

Understanding Climate Change

How do we know the climate is changing? By closely monitoring the Earth's climate system and oceans, and studying the influence of greenhouse gases.

Reducing Greenhouse Gas Emissions

How can we reduce, delay or avoid climate change? Reducing greenhouse gas emissions, using clean energy and storing carbon and crucial.

Adapting to Climate Change

What about unavoidable climate change? Identifying ways to adapt can help communities reduce the costs and take advantage of opportunities.
