We heard the comments during the tour and I just saw this article - http://sg.search.yahoo.com/search/news_sg_pf?p=ukey%3A5652211

Our local weather guy says that we, FL, have had probably the coolest summer on record, determined by the total number of June/July days that were in the 90's. It really has been a great summer thusfar, albeit too much rain.

It seems that one can find facts and data to support whatever position he wants to take. What is your take?

Of course it's warming, due to a strange phenomenom called "summer."

The facts are that nobody really knows for sure. There isn't enough data available that supports any of the extrapolations made today about our future. What do we have, maybe 100 years of temperature readings for a few locales? Considering the age of the Earth, I'd say that's basically insignificant data.

Let's not forget that the Earth has gone through several ice ages where things got pretty cold, and somehow it heated up again. Why? There are theories, but no one knows. Could that same effect be happening now? In other words, is it all natural? I'm not arrogant enough to claim it is or not.

In the meantime, I'm going to take off all my clothes...

Using 1 cool summer in one small location does not refute proof of global warming. We are talking about global temp., not just FL. The globe is warming, that is pretty much universally accepted. The debate is on the cause of the warming (natural, greenhouse gas increases, something else entirely).

I'm only about 80% convinced that greenhouse gasses are the culprit, but the problem is that we'll only know for sure when it's too late to do anything.

One of the main effects of Global Warming is supposed to be an increase in severe weather. Droughts, blizzards, huricanes, el-nino, heat waves, cold spells will all increase in severity, leangth, and frequency. Anybody who points to a single cold weather event (like the blizzards out east this winter) and declares global warming a farce pretty much shows their hand (a straight flush of ignorance)to anyone with even the most basic understanding of the problem.

From everything I've read and seen (including some good science shows on tv) we're definitely in a warming trend. However, it's not too dissimilar supposedly from other heating/cooling cycles according to the fossil records. From my personal perspective, if the glacier melts in the Canadian Rockies are any indication, we are definitely are in a warming period. The European and Asian glaciers supposedly are also following similar declines.

The sixty-four dollar question seems to be whether the trend is part of a normal ecological swing or if and how much is due to a manmade greenhouse effect. And I think the fact is no one really knows.

as somebody else said, there is no long term data to support either side of this issue. Long term data required to support either side might be in order of tens of thousands of years of weather data or even more. As the other person said, the earth has gone through ice ages and warm periods, way before people were burning carbon based fuels.

However, there is a definite political agenda in this argument. Just remember, there is no long term scientific data to support either side.

Funny how some of the hottest temps and heat waves on record were set in the 1800's. The earth just cycles.
