To have “life” as we know it there

must be

 

WATER

 

Just how much water is on Earth?

These figures are from the September, 2013, issue of National Geographic¹. First, apologies to international readers. These figures are in cubic miles. So then:

1 mile = 1.6 kilometers

1 cubic mile = 4.17 cubic kilometers

[America had its best chance to "go metric" during the presidency of John Adams, and we didn't take advantage of it...]

To better understand the water (and some aspects of global warming) examine and compare the numbers below.

How much water is there?

ALL THE WATER IN THE WORLD (in cubic miles)

269   (in) Living organisms

2,752   Swamp water

3,095   Atmosphere

3,959   Soil moisture

42,829   Lakes and rivers

71,970   Ground ice and permafrost

5,614,000   Groundwater

5,773,000   Ice sheets, glaciers, and permanent snow

321,000,000   Oceans, seas, and bays

………………………………………………………………………………………..

• Now if all the ice melts, sea level would rise 216 feet.  (The “ultimate” sea-level catastrophe.)

• Now if just the ice from Greenland melted, sea level would rise 25 feet.

More on water next time…
