- Pro to the question "Is Human Activity Primarily Responsible for Global Climate Change?"
“The Earth’s climate is changing. In most places, average temperatures are rising… The most rapid warming has occured in recent decades. Most of this recent warming is very likely the result of human activities.
Many human activities release ‘greenhouse gases’ into the atmosphere. The levels of these gases are increasing at a faster rate than at any time in hundreds of thousands of years.
We know that greenhouse gases trap heat. If human activities continue to release greenhouse gases at or above the current rate, we will continue to increase average temperatures around the globe. Increases in global temperatures will most likely change our planet’s climate in ways that will have significant long-term effects on people and the environment…
Within the past 30 years, the rate of warming across the globe has been approximately three times greater than the rate over the last 100 years. Past climate information suggests the warmth of the last half century is unusual in at least the previous 1,300 years in the Northern Hemisphere…
If humans continue to emit greenhouse gases at or above the current pace, we will probably see an average global temperature increase of 3 to 7°F by 2100, and greater warming after that.”
