Isn’t the cause more or less irrelevant? The Earth IS getting warmer; there is irrefutable evidence of that as each year sets new heat records in several areas of the globe and extreme weather increases in frequency and intensity. Whether we caused it or not, we are the only force on Earth that can alleviate it. It is in our own best interest to preserve a habitable planet as long as possible. Science tells us that greenhouse gases are a driving force and controlling our own contributions to the atmosphere will help slow down the rate of heat increase. The people who are in a hurry to see the Earth become uninhabitable are the same people who believe that Jesus’ second coming is on the way and the Great Apocalypse will soon be at hand. Anyone anxious to meet their maker is welcome to do so. There are much faster ways to that end.
