What is Climate Change

The What is Climate Change? course, offered by the University of Colorado Boulder through Coursera, is an introductory online program designed to build foundational understanding of climate science, the causes of global climate change, and the critical impact of human activities. This course is part of the Exploring Our Responses to Climate Change Specialization and is taught by Dr. Joseph Casola, making it suitable for learners from all backgrounds, including professionals and students aiming to understand the evidence and consequences of climate change. There are no prerequisites, and upon successful completion, students earn a shareable certificate that can enhance their LinkedIn profiles or resumes for careers related to environmental science, policy, or community leadership.

Core Content

The curriculum spans three comprehensive modules delivering evidence-based insights into the science of climate change. Learners explore the major components of the climate system and examine how anthropogenic greenhouse gas emissions drive global warming. The course presents key physical and ecological impacts, from temperature and precipitation changes to sea level rise and ocean acidification, and assesses the consequences for ecosystems, infrastructure, and communities. Special focus is given to the scientific consensus on climate change, future projections based on emission scenarios, and the negative effects already underway and expected to intensify this century. Students also gain a unique perspective on how scientific knowledge is produced and how credible information is distinguished from misinformation in the public discourse. Real-world case studies, readings—including extracts from the Fourth National Climate Assessment—and interactive assignments help bring the content to life for practical climate communication and action.

Key Skills

Participants develop essential skills in climate science literacy, persuasive communication, and community engagement. They learn to identify credible scientific information, explain greenhouse gas dynamics, analyze climate risks, and evaluate the societal challenges posed by climate change. The course encourages evidence-based thinking, natural resource management, and an understanding of the political and community dimensions of climate action. By engaging with assignments and quizzes, learners become adept at communicating climate science to diverse audiences—an increasingly valuable skill for community leaders and professionals.

Target Learners

This course is tailored for a diverse audience, including college students, educators, environmental professionals, policy-makers, and concerned citizens. Its accessible content and flexible online format make it ideal for anyone interested in gaining foundational expertise in climate science, whether for academic pursuits, enhancing workplace skills, or informed civic engagement. The focus on science communication and audience-tailored strategies also makes it valuable for those involved in public outreach and education around climate issues.

Learning Format

What is Climate Change? is delivered entirely online via Coursera, featuring a blend of brief video lectures, key readings, interactive assignments, and collaborative discussion forums. Learning activities are self-paced, allowing for flexibility and individualized learning journeys. Real-world scenarios and peer reviews support the development of practical communication skills. Upon completion of the required modules and assessments, learners receive a University of Colorado Boulder certificate, serving as a mark of their foundational understanding in climate change science.

Additional Benefits

Participants emerge with a solid grounding in the scientific foundations of climate change, preparing them to navigate misinformation and engage effectively in climate conversations. Graduates join a global Coursera network and gain practical tools for translating science into action, both personally and professionally. The curriculum’s integration of the latest public science assessments and applied communication strategies ensures readiness to lead or support initiatives addressing climate change at community, organizational, or policy levels.
