Climate change impacts everyone — from record-breaking heat waves, to physical and mental health impacts, to food shortages. Understanding the science behind climate change provides you with the foundational knowledge necessary for taking action in your community and enhancing your career. No matter your age, job, goals, or interests, this course will enable you to meaningfully engage with one of the defining challenges facing humanity today.
What is the evidence for climate change? What key concepts describe the physical science of climate change? And are there ways to predict how the climate could change in the future? This short course provides everyone an entry-level overview of climate change science, with no science background needed!
By the end of the course, you should be able to explain the causes of climate change and its impacts. Along the way, you’ll be given opportunities to consider how to apply this knowledge in your own life or career. Learning about climate science is the first step in your journey to becoming a more engaged global citizen as you help determine our planet’s future.
Welcome to Climate Science for Everyone! We’ll begin this week by introducing the course and explaining why understanding climate change science is important to you. Then, we’ll quickly discuss a short history of climate change science. Finally, you will learn about the increase in global average surface temperature since the pre-industrial era in the context of international agreements to limit warming. This will provide foundational knowledge for the rest of the course material.

Drivers of Climate Change: Carbon Dioxide, Methane, and Aerosols
Module 3•1 hour to complete
Module details
This week, you will learn about how human activities have changed the atmospheric concentrations of the two main greenhouse gasses, carbon dioxide and methane. We will also touch on how the atmospheric concentration of anthropogenic sulfate aerosols, which have offset some of the warming from greenhouse gasses, is changing because of pollution control measures.

When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
