Dear Andrew, First, I think your call for something to be done is not only about stopping hurricanes (i.e., when they are fully mature - I can't guess any easy way to achieve this), but also preventing them from developing at once. This seems more thinkable. Basically, it means cooling the

There are already various hurricane-busting programmes. Off the top of my head, these are: 1) Using lasers to discharge lightening in the precursor storms 2) Burning soot in the outer wall to make it absorb heat and cool down 3) Pouring liquuid N2 onto the surface of the sea Sadly these are not

Thank you, The required amount of liquid N2 would probably be gigantic, its production would reject more heat in the atmosphere than the hurricane is consuming, and all it would achieve would be to create, at the surface of the ocean, some cold water, which would very quickly dive down and be

Hi Andrew, Perhaps marine cloud brightening [1] would work. Certainly it would be inexpensive compared to the cost of damage caused by hurricanes - running into $trillions for Katrina: http://www.thedailygreen.com/environmental-news/latest/hurricane-katrina-claims-47010702 It is possible that

John's supposition is correct. Members of our research team are currently performing GCM computations with an ocean/atmosphere coupled model in an effort to determine whether marine cloud seeding could produce sufficient cooling in regions where hurricanes develop to emasculate them.

Hi Albert, Thanks for finding that picture. Where did you find it? The weakening is extremely worrying, considering the sun must still be low (25 degrees?) at its noon elevation, north of 80 degrees latitude. I usually follow this report: http://nsidc.org/arcticseaicenews/ It is interesting

I think that there needs to be a weighting of multi-year(?) sea ice melting at the core of the Arctic Basin in comparison to the any melting of (seasonal ice) at the periphery of comparable size. If the core continues to destabilise, question is why? Nuclear reactors melt at their core, same

Hello Andrew, The fraction of the total energy of a hurricane that is electrical is very small when it is fully developed, and utterly miniscule when it is tiny wee. So what would zapping achieve? Zapping an embryonic hurricane would be no more effectual than a small child in a tantrum -

As I've said in other postings here, I think there will be multiple tools to use against hurricanes. Nothing cools the ocean surface like a storm. So we'll start storms, at places and times that aren't right for them to grow into hurricanes, but still have them passing over part of the area
