The Science Is Not Controversial
Among actively publishing climate scientists, over 97% agree that human activities are causing global warming. This isn't a "both sides" debate — it's a scientific consensus as strong as the link between smoking and cancer.
Fact 1: The Planet Has Warmed 1.1°C Since Pre-Industrial Times
That might not sound like much, but global averages are deceptive. A 1.1°C global average means some regions have warmed 3-4°C. The Arctic has warmed nearly four times faster than the global average.
Fact 2: CO₂ Levels Are the Highest in 800,000 Years
Ice core data lets us measure atmospheric CO₂ going back hundreds of thousands of years. Current levels (over 420 parts per million) are unprecedented in human history. The last time CO₂ was this high, sea levels were 15-25 meters higher than today.
Fact 3: Sea Levels Are Rising Faster
Global sea level has risen about 21-24 cm since 1880, and the rate is accelerating. Thermal expansion (warmer water takes up more space) and melting ice sheets both contribute. Even a 30cm rise threatens coastal cities where hundreds of millions of people live.
Fact 4: Extreme Weather Events Are Increasing
Warmer air holds more moisture, which makes rainfall events more intense. Ocean heat fuels stronger hurricanes. Heatwaves are becoming more frequent and more deadly. These aren't predictions — they're observed trends over the past 50 years.
Fact 5: The Ocean Absorbs 30% of Our CO₂
This causes ocean acidification, which threatens coral reefs, shellfish, and the entire marine food chain. If current trends continue, many coral reef ecosystems will collapse within decades.
Fact 6: Solutions Already Exist
Renewable energy is now cheaper than fossil fuels in most countries. Electric vehicles are reaching price parity with combustion engines. The technology to address climate change exists — the challenge is deployment speed and political will.
Fact 7: Individual Actions Matter, But System Change Is Essential
Reducing your carbon footprint helps, but 100 companies are responsible for 71% of global emissions. Voting, advocating for policy change, and supporting clean energy companies amplify your impact far beyond personal choices.
