Water Mining Prime Culprit For Rising Seas
Nowhere in the Maldives juts more than 10 feet above the Indian Ocean, making it extremely worried about sea level rise. Its president, Mohamed Nasheed, illustrated the point by holding a cabinet meeting under water in the run-up to last year’s Copenhagen summit.
But a new study shows that global warming is not the only cause of swelling seas. Much comes from “water mining” the pumping of vast amounts of groundwater from beneath the earth, mainly to irrigate crops. This inevitably ends up in the oceans after it evaporates from farmland and comes down as rain.
The study which will be published in the next issue issue of Geophysics Research Letters estimates that extraction of ground water for domestic and industrial use accounts for about 25% of sea-level rise around the world, the same as the melting ice from the glaciers outside Greenland and Antarctica.
Even more disturbing is the theory that increased pumping threatens food supplies. Underground reservoirs and aquifers are shrinking by more than 280 cubic kilometres a day, well over twice as much as in 1960. Nature cannot keep pace with the loss to replenish the levels of water tables. The enormous Ogallala acquifer which underlies eight states in the USA, helping to grow food on which people in a hundred nations rely is being drawn down by a three feet a year. How much of that is replenished by rainfall percolation? A mere inch.
Clearly then the blinkered focus of the climte ‘science’ lobby on carbon driven global warming has only served to divert attention from even more urgent and potentially catastrophic problems.
If the atmosphere does warm by as much as six degrees celsius by the end of the century as the most alarmist of doomsday prophets predict, it will not matter because we will all have died of thirst long before that. On the other hand once water shortages start causing millions of deaths thus relieving the pressure of overpopulation on the ecosystem nature will be able to start restoring the balance and the few humans who survive will rebuild civilisation.
Or we could all get the message now, ignore the scintists who are only the hired lackeys of big food, big oil and big money and all just do our best to consume less. There is nothing wrong with using a computer with a I.6 Ghz CPU if it does the job, we don’t have to throw out clothes because they are last year’s fashion and we should heed the old wisdom of the thrifty, buy cheap – buy twice.
All the science I have seen that claims to address his issue, all the statistics that are chanted like mantras and said to support the ‘science’ that was done with made up or manipulated data, all the crackpot geo-engineeering theories and all the carbon trading schemes are aimed at only one thing, not saving the planet but saving the unsustainable perpetual growth economic model.
