Global Warming refers to the increase in global average temperature since the Industrial Revolution. Since 1850, the global annual temperature has increased by .07°C every 10 years, a number that has more than doubled in the past few decades! In total, the average, annual, global temperature has increased by a little over 1°C and is mostly due to human impact. This steep rise in temperature has led to a rapid change in climate all around the world, otherwise known as climate change.
