How does global warming create severe droughts and heat waves?

Posted by admin on November 29, 2012 in Global Warming with 6 Comments


Global warming will cause the rise of the ocean level caused be melting glaciers. Precipitation is sopposed to increase obviously, but how will parts of the world experience droughts and heat waves??

The climate is phenomenally complex, there’s thousands upon thousands of components all interacting with each other. It’s this complex series of interactions that leads to a seemingly paradoxical situation.

The points you mention are quite accurate – ocean levels are rising (by 3.2mm a year) and precipitation has increased (by about 5% globally). With more precipitation you’d have though there would be less drought.

What’s actually happening is pretty much the same as has always happened – the equatorial regions witness the greatest evapouration from the seas and oceans and the winds spiralling away from these regions carry the precipitation to the more northerly and southerly latitudes. If you ramp up this process by putting more energy into the system (ie Global Warming) you accelerate and intensify what’s happening – more evapouration and more rain but falling in the maritime, polar and temperate zones.

The matter is further compounded by a warming of the climate in already arid zones. What water exists here is more readily evapourated by the warmer atmosphere and intensified sunlight, there isn’t enough for saturation vapour pressure to be reached (the point at which it can precipitates) so the moisture is carried away from these hot areas and dumped as rain, snow etc in other parts of the world.

In short – the already wet places get wetter and the dry places get drier. This is happening now in many countries around the world, most notably in Africa and Asia where vast tracts of land have been desertified forcing millions permenantly from their homes.

Caveat: The above is an overly simplified version of what’s happening, the reality is far more complex and many more component factors are involved.

    because the earth is also get much hotter so in some places it just gets hotter and dryer.

    Actually droughts usually happen during or around solar minimums when the sun is to cool to evaporate enough water. This has been the current case since 1998 when the sun began cooling off. But the real problem began 3 years ago when the sun shit down into the deepest solar minimum ever recorded. Currently the liberals do not realize this has happened yet as their minds do not work that fast. Serious scientists are currently evaluating just how cold might it get and how long might it stay cold. The options currently expressed range from a Dalton minimum in 6 to 10 years to a Maunder minimum in 10 to 15 years. Then the older and more experienced ones keep pointing out the very clear records of the last couple of million years of ice ages and pointing out that currently we are a couple of hundred years past the average point of dropping off into a full ice age time wise. So we are watching and it could get very cold for a very long time according to historical scientific records the liberals never read or understood if they did read them.

    It doesn’t, there is no global warming, the planet is cooling!

    To answer this question one would have to believe in the liberal point of view that global warming exists at all. There has been some evidence provided by both the liberal and scientific community to support both sides of the issue. I personally do not believe one way or the other. However, I do believe it is clear that we need to decrease our dependency on foreign oil or any kind of oil at all. I believe we have the technology but it can not be done over night. I believe that each individual can do his part by using solar energy provided by solar panels and wind energy provided by wind mills. I think that we can increase our gas mileage by using HHO gas generators in our cars. Just go to You Tube and type in hho to find out more.

    I guess you didn’t get the memo, global warming is not real, so you therefore dont have to worry bout asking this questions
