Many signs are now apparent, including rising average annual temperature, sea level rise, and changing ecosystems.
Explanation:
The evidence that global warming is occurring is now overwhelming and includes:
- concentrations of greenhouse gases continue to rise causing the natural greenhouse effect to be enhanced.
- as a result, average Earth's temperature is continuing to rise
- warmer air means the ocean waters are expanding, glaciers are melting and this is raising global sea levels.
- the big ice sheets, and smaller ones, are melting back.
- average ocean temperatures are rising (heat from the atmosphere gets transferred to the oceans).
- oceans becoming more acidic as excess CO2 from the air is absorbed into the oceans.
- spring is arriving earlier around the world
- rainfall distribution patterns are changing.
- more frequent heat waves are occurring
