The global warming speech you will find below discusses a topic close to the hearts of many of us. It's a topic that is likely to remain current until measures designed to protect the environment are seen to be having a positive impact. Global warming is the gradual increase of the temperature of the earth's atmosphere and oceans.
Over the past century, the average temperatures have gone up by just over one degree. This may not seem like much, but many scientists agree that the earth's temperatures are starting to increase at a faster rate.
"That so many of us are here today is a recognition that the threat from climate change is serious, it is urgent, and it is growing. Our generation's response to this challenge will be judged by history, for if we fail to meet it - boldly, swiftly, and together - we risk consigning future generations to an irreversible catastrophe."
These are the words President Obama used to begin his global warming speech before the United Nations Summit in 2009.
