onlooker wrote:So, I find this article detailing different possibilities for Geoengineering. I hope you guys can comment as this is looking like maybe the only way left to keep the climate system from becoming totally hostile to most life currently on Earth. In particular Tanada and Dissident what do you think of "Another approach is suggested by Nualgi.com who propose to add iron and other trace metals/micro nutrients to the water in order to stimulate growth of a specific type of phytoplankton called diatom algae, which through photosynthesis absorb carbon dioxide in the water and add oxygen. The oxygen is then used by methanotroph bacteria to oxidize methane. "

Could a £400bn plan to refreeze the Arctic before the ice melts really work?
"We are facing converging cataclysms. When people focus on jobs, economy and retirement, how much will any of that matter if we have a planet that doesn’t support life? If we lose our habitat and every breath we take is full of toxic heavy metal that is making us sicker and dumber by the day . . . . And my only goal is to bring this issue to light and to a halt. We know we have major collusion between all the major powers in the world on this issue. The single biggest leap we can take in the right direction is to expose and stop weather engineering which is weather warfare, and stop these programs (commonly known as chemtrails) in their tracks.” "

Biochar is easier to implement at the local level, using local feedstock's, local construction materials, and local use of the biochar. By applying some permaculture principles the process can be profitable and regenerative. Lots of experimentation is going on with biochar on the small scale (village on down to the individual).

That plan would be an unmitigated disaster. The water below the ice is above freezing, so pumping it out onto the existing ice means it would transfer about half of that energy to the existing ice and the other half to the atmosphere. Given the fact that ice accumulates energy faster than water releases it this plan would not thicken the ice, quite the opposite in fact. The only remotely possible way for this to work would be to desalinate the water into high purity fresh water and then chill it under high pressure. The last step would be spraying it out as a super cooled fluid a few meters above the ice so it will crystallize before reaching the ice floating on the surface. That is an enormously more complicated plan and needless to say it would also cost many times the proposed cost to actually build and operate such a system.
Under the Trump administration, enthusiasm appears to be growing for the controversial technology of solar geo-engineering, which aims to spray sulphate particles into the atmosphere to reflect the sun’s radiation back to space and decrease the temperature of Earth.
While geoengineering received little favour under Obama, high-level officials within the Trump administration have been long-time advocates for planetary-scale manipulation of Earth systems.
David Schnare, an architect of Trump’s Environmental Protection Agency transition, has lobbied the US government and testified to Senate in favour of federal support for geoengineering.
He has called for a multi-phase plan to fund research and conduct real-world testing within 18 months, deploy massive stratospheric spraying three years after, and continue spraying for a century, a duration geoengineers believe would be necessary to dial back the planet’s temperature.
Geoengineers argue that such methods would be an inexpensive way to reduce global warming, but scientists have warned it could have catastrophic consequences for the Earth’s weather systems.
Scientific modelling has shown that stratospheric spraying could drastically curtail rainfall throughout Asia, Africa and South America, causing severe droughts and threatening food supply for billions of people.
“Clearly parts of the Trump administration are very willing to open the door to reckless schemes like David Keith’s, and may well have quietly given the nod to open-air experiments,” said Silvia Riberio, with technology watchdog ETC Group. “Worryingly, geoengineering may emerge as this administration’s preferred approach to global warming. In their view, building a big beautiful wall of sulphate in the sky could be a perfect excuse to allow uncontrolled fossil fuel extraction. We need to be focussing on radical emissions cuts, not dangerous and unjust technofixes.”
A White House report on climate change research submitted to Congress in January called for the first time ever for research into geoengineering.
US Secretary of State Rex Tillerson has also appeared to support geoengineering, describing climate change as an “engineering problem.” ExxonMobil’s funding of the climate denial industry is under investigation by attorney generals in the United States, but it’s less well known that ExxonMobil scientists under Tillerson’s reign as CEO were leading developers of geo-engineering technologies like carbon dioxide removal.
Asked about solutions to climate change at an ExxonMobil shareholder meeting in 2015, Tillerson said that a “plan B has always been grounded in our beliefs around the continued evolution of technology and engineered solutions.”

This is just downright criminal. And insane.
