Climate Change Deep Dive Quiz
From IPCC tipping points to the Keeling Curve, test your deep knowledge of climate science and global warming data.
From IPCC tipping points to the Keeling Curve, test your deep knowledge of climate science and global warming data.
Atmospheric CO2 reached 424 ppm in 2024 — the highest concentration in at least 800,000 years, and up from 280 ppm in pre-industrial times. This 50-question quiz dives deep into climate science, covering IPCC reports, emissions data, tipping points, sea level rise, and the Paris Agreement. With 2023 confirmed as the hottest year on record, understanding climate change has never been more critical.
Atmospheric CO2 hit 424 ppm in 2024, the highest level in at least 800,000 years of ice core records. The Earth has warmed 1.2°C above pre-industrial levels, and 2023 was confirmed as the hottest year ever recorded. This quiz goes deep into the data, science, and policy of climate change.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll explore the Keeling Curve, understand why methane is 80 times more potent than CO2 over 20 years, learn what the Thwaites 'Doomsday Glacier' means for sea levels, and discover how ocean acidification has already increased 30% since pre-industrial times. Every explanation is grounded in peer-reviewed science and IPCC data.
The Earth has warmed approximately 1.2°C above pre-industrial levels. The IPCC warns warming will likely reach 1.5°C between 2030 and 2052 at current rates.
Tipping points are thresholds that trigger self-reinforcing, irreversible changes. Key ones include Amazon dieback (3-4°C), AMOC collapse, permafrost thaw (1,500 Gt of carbon), and coral die-off (1.5-2°C).
The IPCC AR6 report says the world must reach net zero CO2 emissions by approximately 2050 to limit warming to 1.5°C. This requires cutting emissions by about 45% from 2010 levels by 2030.
