Is there any evidence that the world is getting hotter?

There is some evidence to suggest that temperatures are increasing. The Intergovernmental Panel on Climate Change (IPCC) has found that global surface air temperature increased by about 0.85°C (1.5°F) from 1880 to 2012, and the rate of warming over the last century is unprecedented in at least the last 1,000 years.
