GG, isn't it a bit odd to look at the average temp in one place at a particular date to "debunk" global warming or climate change? How have your average or extremes changed over time when including the whole year? Just cherry picking one date may be massaging the data.
Of course I agree that for the last 10,000 or so years we have been experiencing global warming. I'm going to go out on a limb and suggest that what may be the worrisome part to some is the RATE at which the change is occuring. Obviously there are non human factors warming and cooling the planet. What if those factors would actually be cooling the planet now but due to human over consumption the trends still get warmer?
Global temps have risen and fallen in the past. For much of that time the EARTH has existed without much opportunity for human life. It sounds like you are not concerned because the earth's temp can go up and down naturally. I think those people who look at the data are not so much concerned for the earth but for human existence thereon. To be sure, when the globe has warmed enough that humans (and much else) die off then we will no longer be contributing to climate change and if still possible the earth may cool again....
If my use of oil contributes to wars and unrest in certain parts of the world, some of their suffering is because of me. If in future we are fighting over clean water instead of oil, and I waste or contaminate more than my share, then I am unfairly contributing to my neighbor's suffering. If my gluttonous consumption of the earth's resources contributes to California fires, I have a large debt. It is hard for me to imagine that priveleged, wealthy people (us Americans), would continue to exploit other's and then be surprised they don't like us. If I am so complacent in my own life, while maintaining innocence from having any affect on anything, I am naive indeed. And surely, it is for us in the privileged, wealthy part of the world to make the most and substantial changes. Because we have the means to. Expecting others to do more than we do, or to pave the way, is a sure fire way to loose our moral and technological advantage in the future. For the rest of the world we already have, we just don't believe in it yet. It is true, we don't have to care, but the longer it takes us to catch on the harder it will be. I think we will be better off starting now. If we are right we will continue to survive and maybe even thrive for centuries to come. And if we are wrong? Well then at least we won't have made it worse.
