Yes I'm concerned. Climate change aka Global Warming isn't just something that will happen in the future. It's happening now. Widespread drought, rising sea levels, ocean acidification, etc. These are the sort of things that were predicted decades ago. Whatever happens, damage is already done. Species are disappearing at a historic rate, and extinction if forever. Temperature is rising faster than any time in 10,000 years. Feedback processes have not prevented rising temperatures, and aren't likely to do so in the future. Wish I was wrong about all this, but all the evidence says otherwise.

They are recorded in the ice cores, 02 isotopes, mud cores, etc.
Still a guess.

Here are two pictures, one from 1995 and the other from 2015, a span of 20 years. You can replicate this and look at the ebb and flow of the waters over the years using Google Earth's "view historical data".

I hate to disappoint you, but, it looks like the ocean is receeding, not overtaking. The area I chose was the Gulf Coast of FL .... west of Tampa,

That's nice. What were the tides when these were taken? Two points in time, with no knowledge of the tides are hardly evidence of anything. Not disappointed tonight.

Global mean sea level (GMSL) has risen over the past century, largely in response to global warming (~0.19 m rise in GMSL between 1901 and 2010) (1). The response to global warming includes thermal expansion of ocean water as well as mass loss from glaciers and ice sheets, all of which increase the volume of water in the ocean and cause the sea level to rise. Recent GMSL rise has been dominated by thermal expansion and glacier loss, which collectively explain ~75% of the observed rise since 1971 (1). The contribution from mass loss from the Greenland (GrIS) and Antarctic (AIS) ice sheets has increased since the early 1990s, composing ~19% of the total observed rise in GMSL between 1993 and 2010 (1), and is expected to exceed other contributions under future sustained warming [e.g., (2)]. Estimates from short, recent time periods—though not as robust as analyses of longer records because of the dominance of interannual variability—suggest that polar ice-sheet loss may now compose as much as ~40% of the total observed rise in GMSL between 2003 and 2008

I may yet have a chance to wear a heavy coat that has been in closet since move to AZ in 1968 from information in book " DARK WINTER" or " How The Sun Is Causing A 30- Year Cold Spell" by John L. Casey.

The predictions are that we are going into a very deep sun minimum cycle. How that will effect the current climate is unknown but it will have an effect.

We have a diurnal sun cycle currently. During the period of minimum sun, the temperature drops. I suspect that would be the same if the minimum sun period increased. Maybe we should write a proposal to investigate this phenome. I don't think I could get esoteric and overstated enough to describe day and night in such a fashion. However, if there's a million dollar grant to do such a study ... mmm ... something to think about.

If we had a year of lower temperatures, we might drop the "global" average. Of course, since such an activity would be outside the "historic" outliers, we could drop them as if they didn't exist. and continue to show a global increase.

Sounds more like a Thyroid Disorder and medical grants pay more.

I have something that's very thick and the ladies really enjoy.

A southern accent :)
I cringe at the idea of needing to speak Hillbilly because I witnessed incredible ignorance, prejudice, and the use of gratuitous slander as a hobby from the people in that neck of the woods. As far as I can tell, both sides of my family came equipped with an insanity gene, but the Hillbillys had the advantage of isolation, inbreeding, and alcoholism. The Danish side was merely dangerously violent, but they were articulate. It was possible to engage them in a conversation before they concluded that lynching was the proper solution. :eek:

If East Texas turns into West Texas (or into the Gulf of Mexico) I'll move to Colorado just as it's turning into East Texas.
I just came back from vacation in Colorado, and from the license plates it looks like a lot of your neighbors are already moving. :D
I might add, I'm happy the thread lasted long enough to see the controversy.
At this stage it is 10 no concern, 8 concern, 1 undecided and @#12 hopeful so he will have water front property. (missing category) :)

Well I for one have been rather pleased with it in these parts. Its been a decade or more since we last had a nice warm/almost enjoyably hot summer.:cool:

Thanks alot for sending your bad summers to us in OH and PA. Now we have mostly wet and cool (cold?) summers last couple of years.
