The theory is that fleets of ships could spray tiny salt particles, generated from sea water, toward the low-lying marine clouds that hug the coasts of several continents. That would provide the nuclei needed to induce additional droplet formation, expanding the total surface area of the clouds. The resulting dense, white clouds should reflect more heat back into space. A 2012 study led by Latham at the University of Manchester found that the approach could offset the heating that would result if carbon dioxide doubled in the atmosphere.

This is amazing. Humans are perhaps the most interesting species to ever exist, it is crazy what we are possible of thinking, just thinking in and of itself...

Assuming CO2 is to blame and this is supposed to mitigate that, wouldn't having ships run the coasts of 'several continents' every day forever just make the whole CO2 problem worse? The idea of using sea salt to make more reflective clouds is interesting, but I'm struggling to see this as being practical or even effective.

Reminds me of people poisoning snakes and then complaining about mice, so they poison the mice and have dead mice in their walls. Seems like non-venomous snakes were the lesser of two evils.

Except, we have solar power and batteries now.

Exactly what I was thinking.

The impact would be marginal compared to the impact of other emissions sources. At least these ships would be offsetting their impact as well.

Unfortunately water temperature isn't the only thing damaging the reef. We still need to solve the starfish problem too.

Not sure how this is going to change the depth of the coral that grew too high in the water for normal climate oscillations. This is just like how on rainy cool years the savanna plants start to encroach upon the desert and in the hot dry years they die back. You have to remember that the GBR is not "one" organism but several billion and not too bright ones at that - it was growing where it can't survive.

Since the GBR is several hundred miles away from a coastline and we don't want more ionized mercury in the atmosphere I think this described plan is idiotic at best, something created by narrow minded fools who can be manipulated with fear.


The real problem causing CO2 rise and changes in climate is abuse of land use. That deforestation of the rain forests and the heavy industrialized commercial farming destroying large tracts of natural habitat are far more effective at causing atmospheric changes because they destroy the planet's ability to process and store carbon in the form of calcium recombinant life.

Think of the word "terraform" and consider what the primary task of terraforming is: creating a living life supporting environment.

Stop the deterraforming of Earth and the CO2 will drop like a rock.

1. Depth of coral is not what is responsible for the predominance of the bleaching. This argument is asinine, and misleading.

2. Where are you getting ionized mercury? Sea water has elemental mercury in it, yes, but extremely trace. Also, the sprayer technology doesn't rely on ionization. So i am not sure where this mercury is picking up charge.

.

Calcium recombinant life? Are you just making stuff up now? Recombinant DNA is something I used to work with everyday. I don't think you know of what you speak.
