A field guide to a warming world
One atmosphere. One planet. Every degree counts — including at home.
A free, explorative guide to global warming: the physics of why it happens, what it's already doing to rivers, farms and cities across Nigeria and the world, and what you can actually do about it. Built for curious minds of every age.

Who built this
A classroom project, rebuilt as an open resource
This guide started life years ago as a presentation built for a student. It's now been rebuilt from scratch by Babatunde Ayoola Awoyemi — a physicist, STEM educator, and Lead Consultant at Techbase Consultant Services in Ibadan, Nigeria — as a free, open learning tool for anyone curious about the warming world we live in.
Babatunde's own research background is in atmospheric physics and solar radiation modelling, which is part of why this site leans on real instrument-style data wherever it can, instead of vague claims.
