Global Warming

So I was thinking about Global Warming today. I live out in Eastern Washington and it is normal for us to get snow up until June. However as of late the temperature is freakin warm, last year at this time I was in snow boots and snow gear. Now I am in shorts and a T-shirt and its fricken hot, 74 degrees currently.

You can seriously tell that we have some issues with the weather. As far as news goes its been recorded to be the warmest weather at this time of year since 1992 and drought warnings are in effect across the pacific area. Its going to be interesting to see how the weather progresses over the next few years.

Weather has its weird lapses, its happened before.

Well it's been cold for an unusually long time here. It's usually getting warmer by now, but it's just staying cold.

What are the causes of global climate change?

1) long term causes
a) plate tectonics…sufficient amount of continental land mass must have drifted into high latitudes
B) sea-levels must be relatively low
c) land masses must be situated to minimize warm equatorial to high latitude currents
d) atmospheric CO2 levels must be low

2) short term causes
a) Milankovitch cycles

QUOTE Milankovitch cycles

…in 1920, Milutin Milankovitch proposed that climate variations can be linked to:

1) cyclic variations in the shape of Earth’s orbit around the Sun

and cyclic changes in the

2) orientation of Earth’s rotation axis, and

3) the wobble of Earths rotational axis[/quote]

QUOTE Seasons exist because Earth’s axis is not perpendicular to the plane of its orbit…over time the angle of tilt varies between 22.5° and 24.5°[/quote]

OLYMPIA, Wash. -- Washington Gov. Christine Gregoire, responding to predictions of the worst drought since 1977, on Thursday declared a statewide drought emergency.

The first ice age began at approximately 1.8 million years ago dropping down to about 13 degrees celcius on average. Of course it would be warmer close to the equator and colder toward the poles yahdiyahdiyahda. This one was much shorter than the others. At around 1.3 million years ago, an interglacial occured bringing temperatures up to around 14 degrees celcius. A second Ice age occured a few hundred thousand years afterward going slightly deeper down the thermometer. The second interglacial came to around the same temperature and gave way to the latest ice age which happens to be the longest so far. If the current trend continues then we are currently entering the peak of the interglacial. The following dates are extremely in accurate however. The graph does not have a scale with equal intervals. Rather the scale is seperated into the various ages of the Cenozoic.

From this, I believe that global warming is a completely normal proccess. In fact, these past few hundred years we have experianced great fluctuations for both colder and warmer. At about 10000 to 8500 BC, the earth's warming proccess was interupted by a sudden cooling. This cooling wasn't as dramatic as the previous Ice Age however and the earth began it's upward climb once again. By around 3000 BC, the temperature reached its peak, just some partial degrees warmer on a world wide average (of course, in some cases at this time, the temperature may have been one to two degrees Celscius in some parts of the world). This affected much of the world, for example the Nile River transported three time more than its present day volume. For the next 3000 years, the temperature became wild. A sudden cooling trend occured to about 1000 years. Then as slight warming period from 2000 BC to 1500BC. Then another cooling trend lasted till 750 BC. A slight warming period occured, yet the cooling came again. This lasted into the Roman Empire, at it's peak freezing the Nile for one year and the Black Sea for two.

Then a warming period nearly brought the earth up to it's heighest since the beginning of the Holocene. In this period the Vikings settled on Iceland and Greenland and the snow line in the rockies were nearly 370 meters above present day. This lasted from the 900 AD to 1200 AD. Afterwards, the earth experianced a series of rapid and minor climactic change.

Then in a sick encore of the earth's natural ice age cycle, from a sudden warming the earth dropped into what experts call the little ice age. This lasted from 1550 to 1850, with the ends warmer then the middle of course.

From then on however, the earth has been becoming gradually warmer. That's just my two pieces. /dry.gif" style="vertical-align:middle" emoid="<_<" border="0" alt="dry.gif" />

I know, it's usually kind of chilly here still but I was dressed in a pair of basketball shorts and a tee shirt today as well as shorts and a shirt the other days.

Its part of God's divine plan. He's waiting for you all to become accostumed to this odd warm weather. Then he shall smite you all with a bitter flash-freeze blizzard!
