Indicators of a warming world
Humans are warming the planet[1] by increasing the greenhouse gases in the atmosphere. Scientists have many lines of evidence that consistently show that the world is getting warmer. These indicators of global warming (see figure 1 below) include:[1]
- Rising sea levels
- Increased greenhouse gas levels (see carbon cycle)
- Global mean surface temperature increase
- Glacial retreat
- Extreme weather events
- Ocean acidification
- Ocean heating
- Melting sea ice
Visit the above pages for information about each.
