Climate Science and Energy SolutionsCornell Certificate Program

Effective climate action begins with a clear understanding of how climate science is established and evaluated. In this course, you will assess and quantify the forces that stabilize and disrupt Earth's climate system, with a focus on carbon dioxide and its associated downstream impacts that influence climate stability over time. Using examples from Earth's history, you'll examine how natural climate shifts have occurred in the past and why those shifts differ fundamentally from the pace, scale, and causes of contemporary climate change.

You will then evaluate how climate claims are made, challenged, and misrepresented in public discourse. The course focuses on distinguishing credible scientific reasoning from misinformation, denialism, and distortions of scientific uncertainty, while clarifying how scientific consensus is established through evidence and expert evaluation. You'll also assess the feasibility of energy alternatives and carbon reduction strategies across sectors, connecting scientific credibility to the practical evaluation of climate solutions.

By the end of the course, you will be prepared to interpret climate arguments more critically with a stronger grasp of the scientific principles, credibility standards, and solution pathways that underpin climate projections, policy, energy transition, and implementation.

In this course, you will examine how climate models are used to simulate Earth systems, replicate geological and historical climate events, and estimate possible future outcomes under different conditions. This course then explores the validity, assumptions, and limitations of climate modeling, which will help you interpret what models can reliably show, where uncertainty enters the picture, and why uncertainty is a normal and necessary part of scientific forecasting rather than a sign of failure.

As the course progresses, you will move from model interpretation to practical application, using projections to guide regional adaptation decisions. You'll focus on the challenges of applying global climate knowledge to develop locally meaningful planning insights, especially where risk, timing, and vulnerability vary by geography. By the end of this course, you'll be able to interpret projected climate impacts more thoughtfully and use model-based evidence more effectively in regional resilience and adaptation planning.

You are required to have completed the following course or have equivalent experience before taking this course:

• Evaluating Climate Evidence, Claims, and Solutions

In this course, you will examine how climate science, economic reasoning, and international cooperation interact to guide climate decisions. You'll explore how foundational research is synthesized into broader climate assessments and consensus-based guidance, with a focus on the editorial and review processes of the Intergovernmental Panel on Climate Change (IPCC) that shape the clarity, credibility, and utility of those assessments. You'll then examine the constraints involved in producing accurate and relevant climate guidance for the mitigation of climate impacts, including the need to balance scientific precision, accessibility, and policy relevance.

You will also examine how a response can be coordinated on the basis of those assessments, focusing on the economic and political dimensions of mitigation and international cooperation. You'll evaluate the costs of delayed action, the case for early investment in mitigation, and the challenges of aligning diverse interests and values across countries and stakeholder groups.

This course serves as a bridge from climate science and projection to economically sound and cooperative climate action decision making to understand how rigorous assessments, economic reasoning, and equity considerations inform a coordinated approach at national and international levels.

You are required to have completed the following courses or have equivalent experience before taking this course:

• Evaluating Climate Evidence, Claims, and Solutions
• Applying Climate Projections to Regional Planning

In this course, you will examine one of the most important areas for large-scale climate action: energy transition. You'll explore how modern energy systems developed over time, how patterns from past energy transitions continue to shape present-day infrastructure and consumption, and why moving from fossil-fuel dependence to renewable energy involves much more than replacing one technology with another. This course emphasizes the systemic nature of a transition to renewable energy, showing how technical performance, economic incentives, institutions, infrastructure, and public acceptance collectively influence how quickly and effectively energy systems can change.

Throughout this course, you will analyze the major obstacles to renewable deployment, including grid constraints, storage needs, financing challenges, policy barriers, manufacturing gaps, resource constraints, and social resistance. From this analysis, you'll begin designing integrated strategies to advance energy transitions in complex real-world contexts. This course focuses on operational realities of modern energy systems and prepares you to assess energy transition pathways with greater strategic and systems-level insight.

You are required to have completed the following courses or have equivalent experience before taking this course:

• Evaluating Climate Evidence, Claims, and Solutions
• Applying Climate Projections to Regional Planning
• Bridging Climate Science, Economics, and Cooperation

In this course, you will bridge scientific, policy, and energy systems perspectives to apply them to the broader challenge of mobilizing climate impact across individuals, organizations, communities, and governments. You'll examine how climate action takes shape through the interaction of personal choices, organizational strategy, municipal decision making, and multi-level policy frameworks. Rather than focusing primarily on climate science, projections, or energy transition mechanics, this course emphasizes how different actors and different levels of the government influence one another and how meaningful progress depends on collective effort rather than isolated action.

As the course progresses, you will explore how personal and local initiatives can build broader momentum, how corporate and municipal efforts can reinforce or complicate broader climate goals, and how policy frameworks can connect actions across scales to produce larger impact. This course highlights both the opportunities and tensions that emerge when different governments, organizations, and individuals bring various obligations, incentives, and capacities to the table.

By the end of this course, you will think holistically about implementation and how multi-level climate solutions can be aligned to support durable, coordinated, and collective impact.
