Sea rising?

Question

if global warming is not a reality why is the sea rising and ice caps melting.

Answer 1

The sea level is rising because of 2 factors.  Most of the rise is because as the ocean warms it expands and takes of more space.  But the more dangerous rise is from the melting of massive land-based glaciers (the ice mass of both Greenland and Antarctica are decreasing).  Sea ice melting doesn't effect the level.

Answer 2

Its currently rising short of 2mm a year with very slight acceleration (significant when you think about the vast area of the world's oceans, but still tiny when compared to sea level rise since the ice age 18,000 years ago).

Seeing as there has been no warming for 8-9 years, it appears that little thermal expansion has taken place, and water is raised by relatively gently melting of ice (no one can deny glaciers are retreating). Some ice caps are melting yet some are reforming, so I don't know the overall ice change figure.

Sea level rise has the potential to accelerate a lot more if global temperatures were to continue rising (after the significant rise in the past 100 years). Don't forget that water has the potential to absorb a lot of water (albedo level of 0.2 i think), so every inch of extra water constitutes an increase in radiation absorption (especially when compared to ice and snow, which have great reflection rates).

Answer 3

do me a favor.  Place ice in a cup and fill it with water.  Then place a line on the cup where the water line is.  When all the ice melts place a line where the water then will be.

You will get the point of the lie about global warming.

Answer 4

Where is the sea rising?  My grandmother lives in a house on the beach that has been in her family for 150 plus years and the beach is the same as it was back in the late 1800's when photos were first taken...  Where do you guys get this stuff?????

Answer 5

In response to darren s.. take a cup of water.. and do the exact same thing but fill it with ice so that the ice goes above the waterline, like stacking your ice cubes. Mark the water line and not the top of the stacked ice cube, then check back after it has melt.

The ice caps rest on top of the water and not at water level and thus that is why the water line has risen. Take an oceanography class. Global warming is real.

Answer 6

Have you taken core-samples at the arctic recently? Have you noticed a boat in your seaside town lying in the visitor's car park? Then why should I believe you?

Answer 7

Yes.

And global warming is a reality.

"I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”

Answer 8

the actual evidence, as opposed to the hysterical propaganda, is that the sea level expected to rise 40cm in the next century. The Greenland ice is melting at a rate that will take several thousand years to go and the antarctic ice is increasing, with the only part of the continent that is loosing ice is the peninsular and that is due to erosion from sea currents. The arctic ice is sea ice, so if it melts it will cause the sea level to go down, not up.

We have now had 10 years of colder or stable temperatures.

these measurements have been made by the official orginisations that monitor global temperatures, not GW sceptics or oil industry people, and show that global warming is actually much less than was first suspected.

Answer 9

I can't find the link for this, but I read a NASA article that said Arctic melting in the last 3 years has all been caused by irregular winds, and a lot of that 1/2 an inch you're talking about is caused by coastal erosion or land level change. Global Warming is a reality, it's just not caused by us.

Answer 10

if you think its not a reality, then go visit greenland, and watch huge ice sheets melting before your very eyes in real time.

wakey wakey humanity, it will be too late to do anything about it by the time the tide has reached your front door!

Answer 11

Darren, take a look at Greenland and Antarctica, most of the ice is on land. Take a cup and fill it with water, take another cup, fill it with ice and melt it, then pour it into the other cup.

Answer 12

mick t - has some excellent points.  Also why worry about 1/2  inch in 30 yrs?  Just consider how long it would take to rise a foot at that rate, 720 years.

and see the facts.

Climate Change is natural, not caused by Man.  CO2 is .038 of the atmosphere.



"Water vapour is the most dominant greenhouse gas in Earth's atmosphere. It accounts for roughly 60% of the greenhouse effect of the global atmosphere, far exceeding the total combined effects of increased carbon dioxide, methane, ozone and other greenhouse gases."  Shouldn't we be stopping water vapor instead of CO2?  Oh, and all of you who want to go to Hydrogen power, when you burn H you get water vapor, so switching from all fossil fuels to H will drastically increase water vapor in the air and speed up warming by the GW theory.

The fact is the Earth has been warming on average since about 1600.  It has cooled and warmed many times all on its own.  Just before 1600 the disaster was glaciers crushing Alpine villages and the Baltic Sea freezing solid in winter and you can be sure sea levels dropped a bit.  The Earth has been much warmer in the last 10,500 years as well as colder and those changes occurred without Man's influence, just as the present changes,  This last winter set new records for cold and snow, so just keep in mind that they are all just weathermen, making guesses and being wrong.  If they can't accurately predict weather trends a month to a year in advance, how can we believe they can predict it a century in advance?
