“The science is unequivocal: human influence has warmed the atmosphere, ocean, and land.”
What the Science Says
The science behind climate change is clear and undeniable. Global temperatures have risen by over 1°C since pre-industrial times, primarily due to human activities like burning fossil fuels. The Earth’s atmosphere now contains higher levels of carbon dioxide than at any point in the last 800,000 years, and the consequences are stark. Polar ice caps are melting, leading to rising sea levels, and extreme weather events such as hurricanes and wildfires are becoming more frequent and severe.
- Global temperatures are rising at an average rate of 0.2°C per decade.
- CO2 levels are now over 420 parts per million (ppm), the highest in human history.
- Sea levels could rise by 1 to 4 feet by 2100, displacing millions of coastal inhabitants.
