Global warming making water supplies short

Let's see...global warming creates evaporation that eliminates water from our planet.

If we didn't have global warming? Water evaporates that eliminates water from our planet. Either way, being the world is 400 quasitrillion years old, shouldn't water have been extinct 399 quasitrillion years ago? I mean, even ice evaporates!

To quote the great Bugs Bunny... "What a Maroon"

Maybe the Christian evolutionists on the other thread can chime in to tell us how God has done this using evolution :laugh:

 

Global warming is making their brains disappear.

 

Got that one right!!

Since the polar ice caps are melting on Mars, is our global warming causing the evaporation of all water in our solar system? Man...we sure are a powerful species!

 

I would like to stop all GLOBAL WHINING! :laugh:

 

For those interested in a 2nd grade science answer, water on the planet in solid, liquid and gaseous form are in equilibrium with each other. That equilibrium is dependent on the temperature. When the global temperature increases, the equilibrium shifts towards the melting and evaporation direction rather than the freezing and condensing direction. In cooler areas where there is ice and water, it will mean more water. In warmer areas where there is some water and a lot of water vapour, it will mean less water.

 

Well then, that would explain why all those jungles along the equator are so dry. But wait, we don't call them jungles anymore - the name has been changed to rain forest. Funny, calling such a hot dry place a rain forest.

You are right, I should have said warm drier areas instead of warm areas with some water and a lot of water vapour.

Hot humid areas will of course rain and also mountain ranges cause rain formation on one side of the mountain. Global warming may cause a slight decrease in water levels from increased evaporation but probably not a noticeable one in these areas, particularly where there hasn't been massive deforestation. While there will still be rain, the equillibrium of liquid to gas will shift towards the gaseous side of things resulting in increased humidity.

Hot drier areas like most temperate inland plains with few trees where a lot of farming occurs in North America, will experience more dramatic decreases in water levels from increased evaporation.

 

Throughout history different regions have gone through drouts and wet times. Climate happens with or wthout man.

 

Of course there are regional variations. But when there is a general global increase whether from man or not, there will be significant impact on the equillibrium of water in its various states.

 

General as in world wide? There is no evidence of such.

 

The definition most people use is an increase in average global temperature. Average means that while some regions may get cooler, the globe as a whole gets warmer.

There is plenty of evidence that the average global temperature is increasing since the beginning of these recordings in the late 1800s. Data for periods before that are estimated from trees, corals, ice cores and regional historical records.

Climatic Research Unit: Global Temperature record

The Climatic Research Unit is a department of the University of East Anglia in the UK. They collect data from over 3000 temperature stations throughout the globe on a monthly basis.

 

The earths overall temp began cooling in 98. In the 70's scientists were screaming "Ice Age"! This so called science is as biased as BBC

 

Yes that is true. The years since 98 have been among the 10 hottest years on record, but cooler than 98.

I'm not here to convince you of the evidence, just to show it to you. Feel free to stick your fingers in your ears or cover your eyes.

 

NASA - Goddard Institute for Space Studies - Surface Temperature Analysis

NASA's analysis which also includes satellite data suggests that 2007 was on par with 1998 and lower than 2005 which they calculate to have been the hottest year on record. They also have some data on the effects of El Nino-La Nina and solar irradiation which they considered to have been in the "cooling phase" of their cycles in 2007.

 

How does it explain Mars' polar caps melting? It's clearly a Milky Way issue...not a man issue.
