Actually, it's physics. Warmer temperatures will equal warmer ocean temperatures, which are the driving forces of hurricanes. Increasing temperatures will also change and disrupt oceanic water cycles. Simple physics of how things move as they change temperature.
There's already noticeable flora migration. Plants are showing up at elevations and lattitudes they historically have not been seen. Winters here have gotten obviously warmer just in my lifetime. When I was a kid in Morgan Hill, frost and ice on puddles was a common occurrence. Same in San Jose. Now frost in general is rarely seen even in winter.
Regardless, it's STILL a prediction based on conjecture and suppositions.
And isn't an expanded range for plant life actually a GOOD thing? Longer growing seasons and wider ranges of usable land for crops that are now marginal, at best, because of temperatures being too cold? The world CHANGES, which is evident in the geological evidence. The world isn't here merely to suit human beings. It will change whether we like it or not, and whether or not the changes are better for us. We, as a species either have to adapt or, well, die. It is just foolish to expect the world to remain the same just because that is how we have recorded it in the VERY short period of time we have done so. And certainly changes that do take place do not have to be uniformly applied, well, "globally". Why would anyone think it unreasonable to expect that some areas of the globe very well could get warmer, and others get colder? Just as some areas sometimes get wetter and others drier over time. Is not the world littered with ruins from civilizations that existed before us and are now gone? Why is that, do you suppose?
And it is also just as foolish to think of our sun (usually referred to as a
variable star) will be a constant source of exactly the same energy output that warms the earth in the same amount year after year, day after day. Matter of fact there is some evidence that we may be entering a Dalton Minimum, which will mean COLDER temps because of reduced solar activity. I'm sure that anyone can find a theory for just about anything they want if they just look hard enough.
Heck, probably most here don't remember that there was a general concern in the 1970s that we were on the brink of going through a period of global cooling, likely to preface a new ice age. Which, of course, was blamed on human activity.
The universe does not exist merely at our pleasure and for our comfort. And I suggest that scientists are only guessing what is going on around us. Remember, what they are saying are only THEORIES, not proven facts. Theories are only guesses based on other guesses put together in a sales package to the listeners. As I said, little better than weather predictions.
So again, "global warming"? Perhaps "spotty, here and there, now and again warming" might be more accurate.
