All worthless myths!!!!!!!!!!!!!!!

Well, Tommy, I wouldn't go as far as calling it myths. I guess that nobody on the forum is a climatologist with data available for an extensive period of time... etc. You know what I mean. Where's that warming? Mainly in the southern Northern Hemisphere and Southern Hemisphere.

The effects visible at your or my latitude don't really reflect global warming per say, but precipitation changes, dry/wet period changing, weather extremes etc - those are what is visible. And considering the amount of precipitation in the southern America and Africa this year, floods in Pakistan and India, 100°F drought in Russian plains lasting for weeks, 2 significant volcano eruptions in the northern and one in the southern hemisphere... this year ought to be extreme.

Even so, climate science doesn't reflect short term extremes, it reflects long term trends in general. And global, because it is measured globally. So if N.America, Europe and Asia get colder, but Africa, South America and Australia get significantly hotter, it still, in general, counts as global warming.

Even the Basjoos suffered the last few days' chill.

For Italy, search the winter records of 1985-1987. ;)



Human memory is prone to subjective errors. Historical records should reflect the real status.

Just looked at the records that go back to 1924 and found that since January 1990, there have only been 4 hard freezes (below 28). Two of them have happened in the past 2 years. I was quite surprised to find that during 2 periods we were very freeze prone 1956-1966 and 1977-1989

I know it's based on averages, the whole 'global warming' thing, over the course of what, since 1890s or so, something like that. But the reality is in one calendar year, literally 12 months, month 1 and month 12, I've had to cover up, which means "hard freeze". I do not consider that 'normal'. Maybe I've just not adjusted to living where I do from where I did live, which was New Orleans. It's a whole different thing 24 miles across the lake.

But back to the 'global warming' thing. That just doesn't add up to "warming" to me. I know the term 'global warming' is not accurate, as it should be more along the lines of 'global change'. That it actually involves extremes, not constants, not averages - and certainly what one should not expect.

But with the supposed La Nina in action it shouldn't theoretically get cold. Right?

That's how it's been hyped to believe with the weather casts on the news. And that leads to people BELIEVING that they don't need to take precautions. Etc. Now, of course, pay attention to the weather cast at 5 and 10 but come on, stop saying it's going to be 'above average' - which for the Gulf Coast means a relatively "warm winter"!!!!!! Because suddenly if I'm not home...and it gets down to 26...that does not add up to the hype of 'warmer than average winter' and so on. I can't leave my plants in my studio for 3 weeks if I'm not home. Right?

Not so however. I need to get a sun lamp and just stick it out. Low of 29F Sunday morning for the Northshore, which means for where I live it will be 31-34F. So how do I play that one? I'll end up putting everything back in the studio just to be safe.

I need to get my hot house built. Maybe in January when I have some time ha ha.

.

Actually not quite, it depends on where you live. And it mostly affects the regions along the Pacific Rim, though El Niņo seems to reduce, while La Niņa is reputed to increase the frequency and severity of hurricanes on your side of the continent.
See: El Nino La Nina
But keep in mind, that you are dealing with meteorology, like astrology not really an exact science. ;)
Best, Olaf
