Hurricanes are becoming stronger, droughts are lasting longer, and wildfires are spreading through areas once thought to be safe. As these events grow more frequent and intense, it becomes more important to understand what is driving the rise in global temperatures.
At the center of this issue is the greenhouse effect—a natural process that has been pushed out of balance by human activities.
This learning journey explores how greenhouse gases and feedback loops shape the climate while also looking at the ways our everyday choices—like what we consume, how we travel, and the energy we use—contribute to the problem.
Measuring greenhouse gas emissions helps policymakers see which regions and communities carry the most responsibility for climate change, and it also guides the world’s efforts to work together toward climate solutions.
