Answer:
Global warming is a slow and steady rise in earth's surface temperature. Temperatures today are 0.74°C (1.33°F) higher than 150 years ago. Many scientists say that in the next 100-200 years, temperatures might be up to to 6°C (11°F) higher than they were before the effects of global warming were discovered.
