What Is the Climate Crisis?

The climate crisis describes the urgent risks associated with human-driven climate change. Burning fossil fuels and changing how land is used release greenhouse gases that warm the planet.

The consequences reach beyond rising temperatures. Changes in extreme heat, rainfall, oceans and ice affect ecosystems and the conditions people depend on. The risks vary by location, and communities differ in their ability to prepare and respond.

Understanding these connections helps turn a broad global issue into questions we can investigate—and decisions we can improve.

Understand the Evidence Behind Climate Change

How do scientists distinguish a changing climate from a run of unusual weather?

The answer comes from comparing records across time and place. Surface temperatures, ocean observations, ice measurements and atmospheric data provide different views of the climate system. Together, they help researchers assess long-term change and investigate its causes.

Our evidence guide explains what these measurements show, how to read them, and why the timeframe behind a claim matters.

Put Your Carbon Footprint in Context

A carbon footprint estimates the greenhouse gas emissions associated with an activity, person or organisation. Its usefulness depends on what is included and the assumptions behind the calculation.

Learn how to interpret an estimate, identify areas to investigate and track changes without treating a single number as the whole story.
