@onguard, @josefw, @PianoGuy24:Ninety-seven point two percent (97.2%) of climate scientists self-rating their papers endorse the consensus that global warming is real and human caused. Period. Debate over.http://iopscience.iop.org/1748-9326/8/2/024024/As for your comments presumably intended to counter the overwhelming scientific evidence:1. Al Gore is irrelevant. Referring to him does not help your cause.2. Yes, climate has gone up and down. We also know why. In addition to solar cycles, orbital cycles, and so forth, a critical factor is the CO2 levels in the atmosphere. In this case, the climate shift is NOT natural. If humans caused it, presumably humans can do something about it. If nothing else, when you are in a hole, STOP DIGGING.3. Yes, CO2 is “natural.” So is arsenic (an element!). Doesn’t mean it is good for you. I suggest NOT going into a room filled with it and lacking oxygen.4. CO2 is a small percentage of the atmosphere. But it is large enough to do damage through the greenhouse effect, and we now have record-breaking levels of it. High levels of CO2 are associated with higher climactic temperatures throughout Earth’s history. High CO2 then = high climactic temperatures; rising CO2 levels now = rising climactic temperatures. There are some inherent contradictions in your approaches to deny the reality that is anthropogenic global warming, too: claiming that climate change is natural while ignoring that CO2 is a contributing factor to past climate change, for example.You are not having an informed discussion; you are repeating slogans that are increasingly absurd in the face of the evidence. In fact, you are becoming flat-Earthers at just the time when astronauts orbited the very spherical Earth.I would simply feel sorry for you were it not so critically important that people be informed of what is going on, and to take what action we can, before the climate soars beyond what we can manage with our civilization.
