Does carbon dioxide generated by human activities cause global warming? Can i have two points of view?
There are many basic scientific facts which can only be explained if the current global warming is being caused by an increased greenhouse effect due to carbon dioxide accumulating in the atmosphere from humans burning fossil fuels. For example, the planet is warming as much or more during the night than day. If the warming were due to the Sun, the planet should warm a lot more during the day when the Sun has influence. Greenhouse gases trap heat all the time, so they warm the planet regardless of time of day. Another example is that the upper atmosphere is cooling because the greenhouse gases trap the heat in the lower atmosphere. If warming were due to the Sun, it would be warming all layers of the atmosphere. http://answers.yahoo.com/question/index;… We know it’s warming, and we’ve measured how much:
