Comparison of five proposed methods shows they are ineffective, alter weather systems or could not be safely stopped

Large-scale human engineering of the Earth’s climate to prevent catastrophic global warming would not only be ineffective but would have severe unintended side effects and could not be safely stopped, a comparison of five proposed methods has concluded.

Science academies around the world as well as some climate activists have called for more research into geoengineering techniques, such as reflecting sunlight from space, adding vast quantities of lime or iron filings to the oceans, pumping deep cold nutrient-rich waters to the surface of oceans and irrigating vast areas of the north African and Australian deserts to grow millions of trees. Each method has been shown to potentially reduce temperature on a planetary scale.

But researchers at the Helmholtz Centre for Ocean Research Kiel, Germany, modelled these five potential methods and concluded that geoengineering could add chaos to complex and not fully understood weather systems. Even when applied on a massive scale, the most that could be expected, they say, is a temperature drop of about 8%.

The potential side effects would be potentially disastrous, say the scientists, writing in Nature Communications. Ocean upwelling, or the bringing up of deep cold waters, would cool surface water temperatures and reduce sea ice melting, but would unbalance the global heat budget, while adding iron filings or lime would affect the oxygen levels in the oceans. Reflecting the sun’s rays into space would alter rainfall patterns and reforesting the deserts could change wind patterns and could even reduce tree growth in other regions.

In addition, say the scientists, two of the five methods considered could not be safely stopped. “We find that, if solar radiation management or ocean upwelling is discontinued then rapid warming occurs. If the other methods are discontinued, less dramatic changes occur. Essentially all of the CO2 that was taken up remains in the ocean.”

Even the foresting of deserts on a massive scale could prove disastrous if the irrigation needed to grow the trees were stopped, they say. “The desert regions would eventually return to desert and the carbon that was stored in the plant biomass and soil would slowly be returned to the atmosphere through decay and respiration,” says the paper.

Each of the five climate engineering methods considered has advantages and disadvantages but individually they are all limited, say the authors. “If CO2 emissions remain high, the climate engineering methods … should not be solely counted on to prevent warming. Our results suggest that CO2 mitigation seems the most effective way to prevent climate change. Climate engineering does not appear to be an alternative option, although it could be possibly used to complement mitigation,” say the authors, who do not look at the ethical, economic, legal, political or technological feasibility of the five methods.

“The paper sounds a timely warning about the abject stupidity of relying upon climate engineering solutions when reducing our reliance on carbon-based energy systems is the only sensible option,” said Dr Matt Watson, a lecturer in geophysical natural hazards at Bristol University.

“The paper … highlights the urgent need to action approaches to climate change that increase mitigation and adaptation efforts, while simultaneously performing rigorous studies of proposed climate engineering methods. Although some climate engineering approaches, including air capture, may prove useful, they cannot be relied on as a ‘silver bullet’,” said Dr Tim Fox, Head of energy and environment at the Institution of Mechanical Engineers.

Is drought in California Finally coming to an end?

On 12 January 2017 California got some heavy rain from that storm and snow in the ski resorts in California, Nevada but 12 feet (3.658 meters) of snow which would be enough to cause the ski resort to close due to too much snow. With all that heavy rain California but would it be enough to end the drought? Continue reading Is drought in California Finally coming to an end?

EPIC GLOBAL WARMING FAIL!!! IT JUST SNOWED IN THE SAHARA DESERT!!!

Sub for more: http://nnn.is/the_new_media | Mark Molloy for the Telegraph reports, Incredible photos capture freak snowfall in the Sahara Desert, believed to be first time it has fallen on the unforgiving red dunes in almost 40 years. The largest hot desert on the planet, spanning 3,600,000 sq. mi. and many North Africa countries, is not the first place many would associate with a snow during the festive period, with the rare occurrence leaving the man who captured the event stunned.

In a new and particularly foreboding report, the United Nations’ Convention on Biological Diversity warns that using geoengineering to combat global warming should be considered a “highly uncertain” prospect, one whose future impact on the planet’s biodiversity is still unclear.

(NaturalNews) As technology advances big agriculture is discovering new and inventive ways to poison the remaining organic food on the planet, as evidenced by what is currently taking place Down Under.

As reported by WAToday, some South West farmers are drawing attention to what they see as a danger to their ability to make a living after state government officials launched an aerial pesticide spraying program near their organic farming operation.

Using aerosols to block solar radiation represents one approach to geo-engineering

Schemes to tackle climate change could prove disastrous for billions of people, but might be required for the good of the planet, scientists say.

That is the conclusion of a new set of studies into what’s become known as geo-engineering.

This is the so far unproven science of intervening in the climate to bring down temperatures. Continue reading Geo-engineering: Climate fixes ‘could harm billions’
