global warming

Global warming, everyone agrees that something has to be done to reverse the effects of it on our environment. The one problem with global warming is the fact no two climatologists can agree on how dire the situation is.
Everyone who is trying to getting get the point across should be trying to show existing ways of or coming up with ways of their own to help reverse global warming. This is especially true since we have land that we currently view as unusable due to it being to arid to be used along with limitations on our clean drinkable water.
In an effort to counteract the negative aspects of global warming and resulting climate changes, maybe we should be looking at the deserts of the world differently and look to scale up efforts at the commercial desalinization of ocean water in an effort to make arid land sustainable land for crops and small communities.
The only real problem with the world's deserts is the lack of sustained water sources to them on a regular enough, basis to keep it from being usable by our current standards. If we stepped up the commercial desalinization of ocean water to the point that we could send it to the deserts to help create usable farmland and small communities around them to help support the farms, while easing some of the congestion in other areas given a genuine willingness of people to move to those areas.
