Understanding Climate Change

A comprehensive guide to climate science, policy, justice, and action — from tipping points and carbon pricing to migration, geoengineering, and the political forces shaping our response.

13 modules
01

The Physical Foundations of Climate Change

How the greenhouse effect works, why feedbacks amplify warming, and what the carbon budget means for the choices ahead
02

Tipping Points and Cascades

How the climate system can shift suddenly, irreversibly, and in concert
03

The Doubt Machine

How climate denial was manufactured, how it evolved into delay, and why more facts alone won't fix it
04

The Political Economy of Inaction

Why the world has struggled to act on climate change — and what it takes to break that pattern
05

Carbon Pricing

How putting a price on emissions works, where it falls short, and who pays the bill
06

The Renewable Energy Transition

Why the cheapest electricity in history is still losing to the system it should replace
07

Carbon Capture and Removal

What the full portfolio of CDR approaches can — and cannot — do for the climate
08

Solar Geoengineering: Emergency Lever or Planetary Gamble?

What SAI and MCB can and cannot do — and why governing them may be harder than building them
09

Climate Justice

Who bears the burden, and why it is not an accident
10

Climate Migration and Displacement

Who moves, who stays, and who decides
11

Grow Out of It, or Grow Out of It?

Green growth, degrowth, and the question of what the economy is actually for
12

Who Pays for the Transition?

Just transition frameworks, stranded communities, and the politics of decarbonization
13

When Politics Fails, Courts Step In

How climate litigation is reshaping governance, accountability, and who gets to demand action

How this plan was made

Each plan on learnings is built by a hand-crafted agentic pipeline: research agents gather primary sources, a claim reviewer verifies facts against them, and a sequencer orders modules for how people actually learn. The curation — topic selection, framing, editorial standards — is Nicolas's. The research and writing is AI-assembled.
