The story of climate science has evolved over the past 150 and more years. This timeline shows how climate science has built over time, with each discovery adding another piece to the puzzle, and how even overlooked scientists like Eunice Foote made crucial discoveries that we are still learning from today.

What's remarkable is that despite using such different scientific approaches - from simple glass jars to advanced satellites - scientists have repeatedly confirmed that human-produced CO2 drives climate change.

This conclusion has remained consistent since the late 1800s, with each new method and technology providing additional confirmation. By the 1980s, the scientific consensus was clear enough to prompt international action through the IPCC, though the first warnings came nearly a century earlier.
