SO CRAZY IT MIGHT WORK ??? : HOPE FOR PLANET EARTH AS WE KNOW IT









A new study shows how shooting seawater into the clouds could slow global warming.

Padma Nagappan is a multimedia journalist who writes about the environment, renewable energy, sustainability, agriculture, and biotechnology.















It’s one of those ideas that seems too far-fetched to be taken seriously: Deploy a fleet of 1,500 ships across the globe to blast seawater into the sky to make clouds brighter so they reflect more sunlight into space. Why? The deflected radiation would slow global warming—in theory.





Calledmarine cloud brightening,” the geo-engineering scheme proposed by scientists Stephen Salter and John Latham has been bandied about among academic journals for the past 15 years. 



But it seemed impossible to put into practice, as it would cost more than $3 billion just to build the ships. 


Also, shooting salt particles into the clouds would consume far too much energy to be practical.




Now atmospheric scientists at the University of Manchester, in England, think they’ve found an energy-efficient way to brighten clouds. 


In a paper published in the journal Philosophical Transactions of the Royal Society A, lead author Paul Connolly describes how a technology called the Rayleigh jet would be the most effective way to spray seawater into the sky.




A century ago, Lord Rayleigh, an English baron, explained how a stream of liquid would break down into tiny droplets when sprayed into the atmosphere, leaving a residue of salt particles. 




Salter had proposed using silicon wafers to create the tiny nozzles to spray seawater. Connolly’s team focused on calculating how much energy would be needed to create the pressure to pump the water through the nozzles.




Its calculations show that the ships would need 13 megawatts of power on board to generate the Raleigh jets—far more energy-efficient than the other techniques.



“This method of powering the ships will cost about $50 million, which is separate from the cost of building and outfitting the ships,” Connolly said.






“By the end of this century, we think cloud brightening can offset whatever increase in temperature there would be, if we were to carry on as we were with no changes,” he said.




“I’m not saying we should do this, because we don’t know if seeding clouds is going to create other problems,” noted Connolly.



“What this research is doing is just looking into the possibilities—just in case.”



For instance, one great unknown is whether cloud brightening would change global wind and rain patterns. 





“We wouldn’t want to do this and find we might cut off the Indian or Australian monsoon, because then we could affect millions of people who depend on the monsoon as a source of water,” Connolly said.




Like other atmospheric scientists, Connolly thinks that a massive investment in cloud brightening is worth it but mostly as a stopgap measure to slow climate change.



There’s one big catch: The ships would need to spray continuously or the benefits would disappear, because the salt particles only last two to three days.





“It would be a huge undertaking,” Connolly said. 



“But it doesn’t do much about the carbon dioxide in the atmosphere, so what we really need to do is move to a low-carbon society.”

THE MOST SOUGHT AFTER MANGOES IN THE WORLD ....

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

The Chaunsa has a Brix rating in the 22 degree level which is unheard of!
Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

Alphonso (mango)
From Wikipedia, the free encyclopedia








Alphonso (हापुस Haapoos in Marathi, હાફુસ in Gujarati, ಆಪೂಸ್ Aapoos in Kannada) is a mango cultivar that is considered by many[who?] to be one of the best in terms of sweetness, richness and flavor. 


It has considerable shelf life of a week after it is ripe making it exportable. 

It is also one of the most expensive kinds of mango and is grown mainly in Kokan region of western India.

 It is in season April through May and the fruit wei…

Mangoes date back 65 million years according to research ...

Experts at the Birbal Sahni Institute of Palaeobotany (BSIP) here have traced the origin of mango to the hills of Meghalaya, India from a 65 million year-old fossil of a mango leaf. 





The earlier fossil records of mango (Mangifera indica) from the Northeast and elsewhere were 25 to 30 million years old. The 'carbonized leaf fossil' from Damalgiri area of Meghalaya hills, believed to be a mango tree from the peninsular India, was found by Dr R. C. Mehrotra, senior scientist, BSIP and his colleagues. 




After careful analysis of the fossil of the mango leaf and leaves of modern plants, the BISP scientist found many of the fossil leaf characters to be similar to mangifera.


An extensive study of the anatomy and morphology of several modern-day species of the genus mangifera with the fossil samples had reinforced the concept that its centre of origin is Northeast India, from where it spread into neighbouring areas, says Dr. Mehrotra. 




The genus is believed to have disseminated into neighb…
