You may need to check your facts or your math, one or the other. The sun is indeed 93 million miles away, and light travels at 186,000 miles per second, taking approximately 8 minutes or 500 seconds to travel from Sun to Earth.
Light may be fast, but it's not that fast!
You are correct in your other opinions about how powerful it is, though.
OMG! After all of these years of study and a Ph.D., it never occurred to me that those letters "CRC" actually stand for something!
OK. I guess we'll see...
The reports on Arctic ice were taken from submarine measurements made when they surfaced. The fatal flaw in those reports is they did not take in account the cyclical movement and compression of ice towards and away from the north pole. The dreams of a "Northwest Passage" are still dreams. Until man learns to control Earth's climate we will still be at the playful whims of nature.
You are correct. Guess I slipped a mental gear. Or thinking too fast?
Your point is still valid. Melted ice would have more density and displace less of the water around it. 10% less.
Thanks for clearing that up. 10%, not 10x. I am using my telescope right now and was thinking in magnification(x's) when I posted.
''Until man learns to control Earth's climate we will still be at the playful whims of nature.''
I think this is Kyoto's dirty little secret. The U.S. was to be tasked to keep the climate from changing, or die trying.
Water shrinks when it cools (becomes denser) until it gets to about 4 degrees C where it begins to freeze. Then it starts to expand.
Water is the only substance where the maximum density does not occur when solidified.

No. Posting this type of total scientific nonsense should be reserved for Creationist threads. Ice expands by about 9%.
If the Polar Ice Caps melt, Sea Height will drop due to the lack of displacement caused by the lack of expanded water Ice Caps.
Again totally wrong. The floating ice in the North Polar cap could melt and ocean levels would not change at all. Were the South Polar ice to melt, the rise would be about 73 metres. Melting the Greenland ice would only add about 6 metres to sea level. Greenland and Antarctica melting would add to the sea level because the ice currently is on land.
I was corrected earlier in thread, and you are right too. Water expands 10% when frozen, not 10:1. Sorry for the faulty number in my original post. I still stick by the idea that Oceans will recede as ice caps melt.
Why?
Because the North Pole ice cap is floating so it is already displacing its own mass.
The South Pole is ice which is mounted on a land mass, not floating, so if it melts, it will add to the oceans volume, and cause an increase in the sea level.
Thanks for your science lesson. I wish my teachers had been as able as you.
Question.
Why is it only water that expands when it is colder?
Check Archimedes principle. Floating objects displaces their weight and thus when melting, floating objects neither add nor subtract from the volume. Shore ice will add volume because it's new stuff not presently in the oceans.

Even better, took millions of loony left dollars and flushed them!<<
Amen!
Antimony is one of very few substances (bismuth and water are two others) which expands when it cools and freezes. Water expands because it is a polar molecule that forms long chain hydrogen bonds that take up more room as a solid.

BTTT!!!!!!!
Except that some recent research in the vicinity of Greenland/Iceland glacial fields shows that while ice along the edges of glaciers is melting, redeposition of ice back on top of the glaciers is happening at about the same rate. Thus, while the edges of the glaciers may indeed be "melting", nature has a way of balancing things out. Agreed that that may not be happening on all glacial fields, but all of them haven't been studied for it.
That plus the fact that there have been glacier fluctuations from a "millennial-scale oscillation of climate that operates on a broad scale" and that we are probably just coming out of a mini-ice age (1600-1850). These cycles have been identified and the conclusion is that the "current recession of many of earth's glaciers is seen to be but the most recent phase of a naturally-recurring phenomenon that has been 'doing its thing,' over and over, without any help from variable greenhouse gas concentrations, throughout the entire last half of the Holocene." Which is something like since "between 6000 and 5000 years before the present (BP)." And more than likely, even longer than that. That's just the time period that was studied.
Another wail of "the sky is falling" global warming alarmists is the increasing levels of CO2, a "greenhouse" gas which is blamed for the global warming. Interestingly enough, the increases in CO2 have seen a commensurate increase in the root structures of certain trees that were being studied. The eco-nazis can't see the increase in plants growth from added CO2 because a lot of it is invisible beneath the ground. But the CO2 sinks of plant vegetation can handily take care of what is being added to the atmosphere. That's exactly why they call it a bioshere or ecosphere.
All of the junk science, "the sky is falling" nonsense that the envirowackos spew forth is being whittled away by actual real science done by real scientists. It's just that the real science isn't being reported by the MSM, only the liberal eco-nazi scare tactics.
