Understood, but when you say "warmest in history" you need to qualify that statement. "Warmest in the continental US since they've kept records" is a completely different statement than "warmest in history." I'm not as concerned with what I am too stupid to understand, but rather, what other morons are too stupid to understand, and we need to clarify things like this.
Now, because you may have evidence to suggest that we've recently seen the warmest recorded temps in the continental US since they've been keeping records, this does not prove that man is causing global warming. Just as when ANY record is set, and this happens all the time, it doesn't mean that man caused it to happen. One thing is, we've only recently reached a level of technology and accuracy with regard to measuring, to actually record accurate data. In 1776, there wasn't a NOAA weather station in Colorado, recording the highs and lows. So this whole "warmest in history" argument becomes even more moot. There is simply a lot of information missing, that was never recorded, and we can't make assumptions based on no information. To draw obscure conclusions based on such little actual data, is foolish at best.
It is a FACT, the planet has endured much warmer climates and much colder climates through history. Since this has never resulted in some irreversible cataclysm, it's safe to say that isn't going to happen now. The old Earth will always find a resilient way to overcome, because it always has. Man has dumped millions of tons of toxins and pollutants into the air and water, and as bad and harmful as this is, it pales in comparison to what mother nature herself has contributed, but still, the old Earth continues on. In time, it filters and cleans up the mess, and returns to relative stability in short order. This doesn't mean we shouldn't be good stewards of the planet, or that we shouldn't be conscious of what we are doing with regard to pollution, but the extremist alarmist "sky is falling" paranoia is totally unwarranted.
