Introduction

This report presents eight data-driven visualizations exploring key indicators of global climate change. The figures draw on publicly available data from NASA, NOAA, the Global Carbon Project, and Our World in Data. Together they illustrate how atmospheric CO2, global temperatures, sea levels, and extreme weather events have changed — and are continuing to change — over the past century.

Figure 8 — Interactive Bar Chart: Extreme Weather Events by Decade (Interactive)

Conclusion

Across all eight figures, the evidence consistently points in the same direction: atmospheric CO2 has risen steadily since measurements began, global temperatures are warming at an accelerating rate, sea levels are climbing, and the frequency of extreme weather events has roughly quintupled since the 1950s. Encouragingly, Figure 7 shows that renewable energy adoption is increasing across every region — though Figure 4 underscores that the largest emitters still have the farthest to go. Taken together, these visualizations paint both a sobering picture of the challenge ahead and a reminder that measurable progress is possible.
