since modern meteorological records began in 1880, nine of the last 10 years have been the warmest wherein 2010 was the warmest.
"As greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed, most notably since the late 1970s." NASA
Since 1880 the carbon dioxide level in the atmosphere was approximately 225 parts per million (ppm), but since 1960 the average amount rose to be 315 ppm. Today however it's more than 390 ppm and continues to increase to rise at an accelerating pace.

In Berkeley Earth's video animation below, is a map of the world showing a temperature rise from 1800 to the present. The Berkeley Earth historical analysis demonstrates a 0.911 degrees Centigrade of land warming (+/- 0.042 C) since the 1950s, and the chart at the bottom, shows the global land-surface temperature accelerating exponentially. Reds indicate temperatures higher than the average during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average.
Phew, things are hotting up, eh? If political leaders and governments continue to baulk at addressing climate change and global warming then perhaps we ought anticipate massive increases in trans-migratory shifts of human populations to be seeking cooler climes ?
