re HAARP
An SAI program could limit global temperature increases, reducing some risks associated with higher temperatures and providing the world economy additional time to transition from fossil fuels. The process is also relatively inexpensivethe National Research Council estimates that a fully deployed SAI program would cost about $10 billion yearly.
As promising as it may be, moving forward on SAI would raise a number of challenges for our government and for the international community. On the technical side, greenhouse gas emission reductions would still have to accompany SAI to address other climate change effects, such as ocean acidification, because SAI alone would not remove greenhouse gases from the atmosphere.
On the geopolitical side, the technologys potential to alter weather patterns and benefit certain regions at the expense of others could trigger sharp opposition by some nations. Others might seize on SAIs benefits and back away from their commitment to carbon dioxide reductions. And, as with other breakthrough technologies, global norms and standards are lacking to guide the deployment and implementation of SAI.”
So. Terraforming the planet to receive less sunlight. And trying to lower the CO2 levels back to near plant starvation levels.
For what species are they terraforming the planet...?
From what I understand, that was the setup for the movie Snowpiercer.
