Since the start of the 20th century, humans have propelled the rise of the average global temperature by 1 degree. Just for some comparison, during the ice age, the average global temperature was 9 degrees lower than it is today.
"Since the Industrial Revolution began in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methane levels have increased 148 percent".
