Everybody is talking about "global warming" and "climate change" but what is global warming actually? Is it true about the theory that human activity is responsible for global warming?

It's when the earth becomes too warm due to carbon dioxide accumulation and other factors that the ice in the northern and southern hemispheres begin to melt. Global warming is bad because there will be drought in many places like in Africa and humans, animals, and plants will perish. Yes, it is caused by human activity such as using your car too much or any other activity that emits carbon...

Thanks for your response..But im just curious if there is a convincing scientific evidence that human release of carbon dioxide will cause catastrophic heating of the earth's atmosphere and disruption of the earth's climate?
