Global warming is something that a significant majority of experts are now predicting as something that is starting to show its effects, and that the changes so far are just a preview of the major changes that are predicted to happen. The problem being that the world weather pattern is so complex to simulate and calculate that there is no easy way to show a set of equations about what is happening and going to happen, and that leads to the doubters being able to declare that the whole thing is over-blown.
In a 67 page section detailing the impact of global warming on North America, the report makes for scary reading. The major effect is the impact on the availability of water. Water levels overall are going to less available for the population, and we know that the population levels are not going to go down, only up. If people will recall the major discussions in the past 2-3 years between the south-western states over the usage of river water, then they will realize how the shortage of water is going to affect them. And this is not something that is a few generations down, but the current models show that water levels are already declining, and in a couple of decades, the effect will be very noticeable.
And yet we see not too much concern among the Governments most likely to contribute towards warding off Global Warming, either with high existing levels of energy consumption or fast increasing levels such as the US, Russia, Australia, China, India, etc. But one can already start to conclude that fears of economic problems if pollution conservation measures are made more strict pale in comparison to what will happen 10-20 years down the line when the true impact of global warming starts to unveil. These involve climatic disruptions, water level rising engulfing coastal regions everywhere, and the impact on water. Read this news story:
As the world warms, water – either too little or too much of it – is going to be the major problem for the United States, scientists and military experts said Monday. It will be a domestic problem, with states clashing over controls of rivers, and a national security problem as water shortages and floods worsen conflicts and terrorism elsewhere in the world, they said. At home, especially in the Southwest, regions will need to find new sources of drinking water, the Great Lakes will shrink, fish and other species will be left high and dry, and coastal areas will on occasion be inundated because of sea-level rises and souped-up storms, U.S. scientists said.
