Extremely difficult global warming problem?

Question

When ice melts it takes up 92% of its original volume as water. Let x% of Earth's total floating icecap volume be above water, and let y% be below water. Earth's floating icecap volume is z% of Earth's total icecap volume. If z>0, by what percent must y decrease in terms of x and z so that no change occurs if Earth's icecaps melt?

celebrity girl i agree

use your IQ to fight global warming!

Answer 1

Wow - I think I just zapped into a parallel universe...
just look at all those %%%%%%%%

I have the same problem when I dangle all 6 legs in the swimming pool...

if you measure the earth through the poles the circumference is 40,008 km. The earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like). But lets ignore this problem cos it makes the answer harder...

Continuous observations with VLBI and GPS are carrying out at Ny-Alesund, Svalbard in Arctic and the secular vertical displacement rate is found to be 5.6 +/- 2mm/yr over the last 8 years (this is consistent with your 92%). Moreover, absolute gravity measurements have also been carried out four times since 1998 by three different institutes and these observations indicate a rate of about -3 mGal (1 mGal =1 × 10-8 ms-2) for the secular gravity change (i.e. the secular decreasing in gravity). Assuming that no significant mass movements below or above the gravimeter take place, the gravity change corresponds to a secular uplift of about 9 mm/yr. The observed rate is far larger than the uplift predicted by several post-glacial rebound (PGR) models for the western Svalbard (of the order of 1 mm/yr) and/or the rate deduced from studies for the raised shore deposit (about 3 mm/yr). We have estimated the effects of the mean sea level (MSL) changes and of the present-day ice melting on the geodetic measurements carried out at Ny-Alesund. For the effect of MSL changes, our estimation based on the tide gauge data compiled at the Permanent Service for Mean Sea Level indicates +0.10 mm/yr and -0.04 mGal /yr for the vertical displacement and gravity changes, respectively. Therefore, this effect is too small to explain the observed rates. For the effect of ice melting, our comparison between the model computations and the observed residuals after removing the PGR effect indicates that the glaciers in Svalbard are melting at a rate of 40 cm/yr -- 100 cm/yr as a mean over the Svalbard islands. The obtained rate is not inconsistent with the rate estimated from the glacial morphological studies. To constrain tightly the rate of ice melting by the geodetic observations, the effect of regional tectonic motion on the displacement and gravity in Svalbard needs to be estimated.

I hope this helps...

Sigh -- back to reality now... Devilia get me out of here...

Answer 2

Floating ice is a non-issue: just like in a glass, the water does not rise when floating ice melts (because the liquid water takes up exactly as much volume as the below-the-waterline portion of the solid ice, that's why).

The problem comes when glaciers on land (like in Greenland or Antarctica) melt or slide into the sea. THAT's what raises sea levels.

Answer 3

genuine volcanoes will erupt devoid of help quickly adequate. Earth has worldwide warming cycles of 12,900 years, the comparable cycle that earth variations it relatively is rotational axis with the aid of a hundred and twenty stages. This actuality is lots previous shown, whether many ignorant scientists with exposure at the back of them a approach or the different are obstructing the actuality. examine Walter C Wright's 'Gravity is a push'. it isn't the terrific e book ever, yet has a lot of stable references.

Answer 4

Shouldn't the Y value have to increase? The larger Y area, the larger the coolling effect. Which directly effects the Z quotient.?

Answer 5

i am confused!!!i can say that i have i warned many people through the Internet to start a revolution & have even sent a mail on my opinions to bbc and they think i am o.k.sorry dude i can't answer the above question IT'S TOOOOO TOUGH!!!!!

Answer 6

Global warming should be a concern for everyone.

Answer 7

Wow that is a problem! I believe you left me behind at x% though.

Answer 8

Math wasnt my specialty.. so I have no idea.. but Ill check back to see who does...

Answer 9

math wasn't my strong point, either, but...that just doesn't make any sense to me...no matter how you look at it, there WILL be change.

Answer 10

HAHAHAHAHAHAHAHAHAHAHA AL HAHAHAHAHA
