Global warming, the phenomenon of rising average air temperatures near Earth's surface over the past 100 to 200 years. Although Earth's climate has been evolving since the dawn of geologic time, human activities since the Industrial Revolution have a growing influence over the pace and extent of climate change. What is global warming? A: Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature. This poses many Global warming describes the current rise in the average temperature of Earth's air and oceans. Global warming is often described as the most recent example of climate change.
