I am fascinated to know the answer to this question. Earlier this year,
the East Coast USA had more rainfall than normal and the Midwest had a
drought. So if we added the two together is it a approximate
zero-net-sum. If it is, then whenever one region of the country gets
too much rain from their normal amounts means another region will have
extended droughts.

The underlying physics would say the answer is yes, because Earth as a
total system can only support a specific range of rainfall due to the
energy it gets from the Sun. So the rainfall in total is a given
amount, and if one region gets too much then another region must get
that amount less.

Now the model I am thinking of is that of a lid on a pot of heated
water. Only the lid has variable shape from that of perfectly flat to
that of curved inward and curved outward from the water that is heated.
In various shaped, the amount of water that is evaporated, condensed on
the lid and then falls back into the pan will imitate rainfall. It is
Zero Net Sum because no water is allowed to escape (at least we try to
prevent escape).

Now in the flat lid the water drops uniformily and in the concave
outward the water falls more near the edges of the lid.

I am modeling Earth with global-warming. And that means that rainfall
given up in hurricanes and dropped on the coastal regions means that
other regions will have to suffer droughts. Much of the USA interior
has become dryer and dryer since 1994. Concomitantly, the East Coast
USA has become flooded out region.

Global Warming may increase in a small amount the total rainfall over
the Earth, but global-warming causes the rainfall to concentrate on
coastal areas, thus making the interior of continents more arid and
desert-like.

So if we continue on the same path for the next 20 years, the USA will
have a desert for the Midwest instead of farmland and agriculture. And
the coasts will be flooded yearly with too much water.

I propose Thistle Seed (or pulverized paper fibers) Released by
airplanes in the apogee of their flightpath to solve this problem. To
reflect sunlight and to imitate Pinatubo volcano to make a cool summer
with plenty of rain in 1992-3.

I ask all farmers in the USA to join together. I just spent a lousy 2
months of mostly 40 C (100 F) days and having to water my plants from
the drought. And I am sure many farmers have experienced worsening
droughts starting in year 2000. Unless we join together and demand that
Washington act on global warming such as the Thistle Seed program. That
the farms of the Midwest are heading to be dust bowls. And unless you
want to grow crops of cacti, then demand that our politicians act to
solve this global warming.

Sure it is nice, like last winter of 2005 where it is so mild and warm,
but the flip side is that come every summer there is no rain and we
have to endure months of temperature over 100 degrees F.

So I call on the farm community, that this global warming is a threat
to your livelihood, a threat to your farm. And to force and demand the
politicians to start a program to put something in the air that gives
us cool summers and wet summers.
