Yeah, in some ways, it would be "better" if we had a string of weather catastrophes. In a general sense, human beings are fairly selfish. We don't really take action unless something personally affects us. While the data indicates things are getting hotter, it is not in a way that can really be measured by anecdotal recollections. We only remember the extremes that stand out to us because those affected us personally ("I remember the summer of '83 being so hot.....").
If a catastrophe happened like what happens in some of those disaster movies, it would be easy for us to say, "Yup, this is a problem, and it's big enough we need to do something about it." Since we can't really "feel" the difference because it has stretched over decades, we can't mobilize enough people to change accordingly.
One thing I noticed a few years ago that I am curious about is fall foliage. Two years ago, the leaves didn't start to turn until much later than usual (at least, here in central Ohio). When they did turn, they didn't start to fall until the first week of November or later. Last year was closer to normal (mid-October), but this is something I am going to pay attention to a bit more this year to see if two years ago was just a one-off or whether there is a trend. I seem to recall that when I was younger, the leaves were always on the ground by mid-October (anyone else remember those Hefty garbage bags that were bright orange with a jack-o-lantern face that you could use as a cheap Halloween decoration when you filled it up with yard leaves? I don't think I've seen those in a long while now and I'm wondering if it is because the leaves aren't falling as early as they used to). My understanding is that there are several factors that can go into that besides temperature (rainfall, number of hours of daylight, etc.), but just something to keep an eye on, you know, from an anecdotal standpoint.....
