"It seems incontrovertible to me that there is a global warming effect and that it is going to be serious, probably not in the amount of, say, six degrees warming, but it's likely that we'll get two to three degrees warming and that will be serious enough"

This quote by Bjorn Lomborg suggests that worldwide warming is an obvious reality which its effects will certainly be serious. He believes that the temperature level of the Earth will climb by two to three degrees, which suffices to cause severe damages. He does not believe that the temperature level will increase by six degrees, which would be catastrophic. Lomborg's quote indicates that we have to do something about it to reduce the results of global warming, as 2 to 3 levels of warming will still have a considerable effect on the environment. Lomborg's quote is a suggestion that we need to take actions to minimize our carbon exhausts and also protect the atmosphere, as the impacts of global warming are real as well as will be significant.
