There is overwhelming scientific evidence for climate change:
1. Rising Global Temperatures - Global surface temperatures have risen by about 1.2°C (2.2°F) since the late 19th century.
2. Ice Sheets and Glaciers - Greenland and Antarctic ice sheets have lost hundreds of billions of tons of ice per year.
3. Rising Sea Levels - risen by about 8–9 inches (21–24 cm) since 1880 due to melting ice and thermal expansion.
4. Ocean Warming and Acidification - 90% of excess heat from greenhouse gases is absorbed by the oceans, causing marine heatwaves.
5. Extreme Weather Events - More intense heatwaves, droughts, wildfires, and hurricanes have been recorded.
6. Changes in Plant and Animal Behaviour - Species are migrating toward poles
7. Carbon Dioxide and Greenhouse Gas Levels have risen from 280 ppm (pre-industrial) to over 420 ppm today, the highest in at least 800,000 years.
