Answer:

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
