The Gulf of Mexico is 5 degrees warmer than normal while the Atlantic ocean is a couple of degrees warmer than normal. THAT is the cause of the hurricanes.
Whether this local water effect is related to global warming is unproved just as whether man is causing any part of the global warming is also unproved.
Global warming, however is a fact.
Glad of it too. Earth would be uninhabitable if it wasn't. -18 degrees C IIRC.
Anthropogenic(man-made) global warming is still just a theory, and likely to remain so.
There is no normal temperature; there are averages for those areas where instruments have been in place for a long enough period to be considered normal from shared experience.
>>Global warming, however is a fact.
If the temperature should go down one year...you'll never hear about it.
True...the earth has been warming ever since the last ice age. Abnormal warming is a theory, a bad one at that.
