 Well, actually, yes, there's a lot of confusion and I don't understand the argument over empirical evidence and observations of things like ice, because ice is nature's best thermometer. When it warms up, it melts. If it's cold, it doesn't melt. And so the earth is clearly warming because we're losing a lot of ice, especially from glaciers. And all you have to do is look at sea level. Sea level is the best indicator of whether the climate is warming or cooling, because when the climate is cooler, then you have more ice from the oceans, which falls as snow. It's stored on land and sea level falls. When it's warmer, you are melting ice on land and that's raising sea level. And sea level has been rising and is continuing to rise. There's no question about this. So I'm really puzzled and don't understand why a very vocal small minority of people ignore very simple empirical evidence that the earth is warming.
