Scientists told UK MPs this week that the possibility of a major methane release triggered by melting Arctic ice constitutes a "planetary emergency".

The Arctic could be sea-ice free each September within a few years.

Wave energy pioneer Stephen Salter has shown that pumping seawater sprays into the atmosphere could cool the planet.

The transparency of your logic is obvious
Okay, now that there is something there,

The idea of putting dust particles into the stratosphere to reflect sunlight, mimicking the cooling effect of volcanic eruptions, would in fact be disastrous for the Arctic, said Prof Salter, with models showing it would increase temperatures at the pole by perhaps 10C.

And last year, the cloud-whitening idea was also criticised by scientists who calculated that using the wrong droplet size could lead to warming - though Prof Salter says this can be eliminated through experimentation.

Sounds like a pretty complex attempt. Better get those droplet sizes right. I imagine the amount of methane released will be enormous, granted probably most of it will be a slow release, but I wonder if there will be vast bubbles that release a cloud big enough to effect a village/community.

Cloud brightening is a developing type of geo-engineering that may one
day help slow climate change and tackle global warming. Scientists aim to
add salt particles to sea clouds, for example via remote-controlled boats.
The salt particles would make more droplets of water form in the clouds,
so that they appear whiter and brighter. These whiter clouds would reflect
back more light and heat from the Sun, which should help cool the Earth.

Do we only need to add salt to the clouds
once to brighten clouds?
To keep the clouds bright the salt would need to be continually added. The
effect of adding salt to brighten the clouds should be seen quickly, but it
would disappear in about ten days if we stop adding salt.

How is this different from weather modification?
Cloud brightening is not designed to make it rain, or stop it from raining, in
a specific place. Ideally there would be no change in weather patterns, just
brighter clouds that reflect more sunlight away from the Earth’s surface.
However, until there are large-scale trials it will be hard to say what changes
might happen to weather patterns.

All these technologies and strategies are only going to temporarily delay a natural cycle and at what unimaginable expense?

And perhaps gain some time to make the necessary adaptations? Humans aren't much good at doing anything in a hurry.

Surely someone can find a way to breed white grass. Heck it might even be cheaper. Personally I say just leave it alone and learn to adapt. Everytime we try to fix one mess we create another.

And why pretend to ban it on one hand, change to the bland term "adaptation" (which won't show up on search engines like geoengineering will), and continue the planning????
