Geoengineering encompasses a broad range of activities, including those that intentionally attempt to cool the Earth or remove certain gases from the atmosphere. Gases that trap heat in the atmosphere are often referred to as greenhouse gases, which include carbon dioxide, methane, nitrous oxide, and fluorinated gases. For example, geoengineering includes the removal of carbon dioxide from the atmosphere (also called Carbon Dioxide Removal – CDR) through methods such as direct air capture and storageocean iron fertilization, or ocean alkalinity enhancement.

A subset of geoengineering activities intends to cool the Earth by intentionally modifying the amount of sunlight reaching Earth’s surface. These activities are referred to as Solar Geoengineering or Solar Radiation Modification (SRM). Most proposed solar radiation modification techniques involve adding material to the atmosphere to increase the amount of incoming sunlight reflected back to space. While some of these approaches are currently being studied, not enough information exists to fully understand the viability, risks, and benefits of each approach. 

Types of solar geoengineering techniques include: 

  • Stratospheric Aerosol Injection (SAI) – adding small reflective particles to the upper atmosphere (stratosphere) to reflect incoming sunlight. Sulfur dioxide (SO2), one of the types of chemicals considered for SAI, can chemically react in the stratosphere to form reflective sulfate aerosols.  
  • Other techniques, such as Cirrus Cloud Thinning (CCT) or space-based methods have been far less researched due to uncertainty in the processes, high potential costs, and more limited feasibility. 

Potential Impacts

The purpose of solar geoengineering is to cool the Earth by reflecting more sunlight back to space. Depending on the approach used, there could be additional unintended health and environmental consequences that require careful evaluation. Current understanding of risks and benefits is limited by uncertainties in the observations and modeling tools used to examine solar geoengineering impacts. There isn’t enough information available to fully understand the unintended consequences of solar geoengineering. 

Potential health and environmental impacts of solar geoengineering include: 

  • Ecosystem health and crop yields – adding sulfur to the atmosphere increases the risk of acid rain, deposition of sulfur to the surface, and worsened soil acidity, which could impact food production. Decreased sunlight (i.e., energy) reaching the surface could also impact ecosystem and agricultural productivity. 
  • Rain and snowfall patterns – adding particles to the stratosphere can alter hydrological cycles, leading to changes in the amount of rainfall and drought in specific regions. 
  • Respiratory health – some particles in the stratosphere eventually come down to Earth’s surface where they can contribute to adverse health impacts, including making it difficult to breathe.

  1. WOW Peter, you’ve already returned to the monkey stage. Just a word of advise for you. Whilst you’re out hunting & gathering make sure you secure your digital devices to your tail so you can youtube how to rub 2 sticks together to create some smoke OR gas!

  2. Science is not science any more, its a big ego trip.. and peer reviews across all sciences went out the window long ago. Nobody reads anything just agrees and fakes it more times than not. Science is ruining this planet and they are blaming it on man. Its just a big ego trip for them – but the Earth will rebel, you can count on that.

    Our magnetic field is changing and with it comes heating of the planet, this is a natural cycle that is repeated on a regular basis and they are cashing in on it and us.

    Does anyone remember this? They tried this all once before but got caught out.., why should anyone ever trust them again, but most people don’t remember because they are purposely distracted by other stuff.

  3. God, or our Creator …. and there has to be one as everything is in sync on the planet…until Man came along and tried to change it!
    Man cannot play God and get away with it….I can’t waIt for their time to come!

  4. The facts are demons in control and loaded. Our protests, effective as pissing against the wind, with the system firmly entrenched. They’ve been spraying all (themselves inclusive) like flies since Port Arthur, probably earlier.
    Jabbed and boosted glued to iPhones who bothers to look up anyway?
    Dependant like newborns to the tit, most are compliant in fear of losing jobs in the survival hunger games that is life down under the krown kabal komo digital gulag hell enforced by brain dead zombies. Sad to say, we are in the beast system, thinking it’s a fairy tale doesn’t help.

  5. Earth is the most perfect habitat for us all with its four seasons, abundance of a smorgasbord of food and vitals and the only one within millions of light years of us, so what’s their problem? It’s almost like it was designed for us and all the creatures on it. One can only think these idiots are Satanic or blind from industrial greed and committed to their ongoing desecration of it. It ain’t broken, it needs no ‘fixing’.
    Same theory as the toxic jabs, was it to desecrate us because we are said to be in God’s image in human form and so perhaps also Earth is God’s work and the forces that run the show don’t like it.

  6. Man thinks he has the capacity to alter the planetary environment. It is man’s own arrogance that claims such abilities. Man is naught. Without God he couldn’t get out of bed. Meaning he hasn’t got the capacity to alter the planetary environment in any degree. These fools are megalomaniacal creatures of incalculable self absorbed stupidity. They have no ability to get out of their own bed without Gods approval and ascent. It is in fact laughable that we even bother to pay them any attention at all!

  7. Geo-engineering is founded on ignorance and stupidity. Ignorance of the way the world was created and how it functions. Ignorance of the designer and creator of the world. And stupidity to believe that they know how to fix non-existent problems and think they have the ability to do so. God looks on them as insects:
    “It is he that sitteth upon the circle of the Earth, and the inhabitants thereof are as grasshoppers:” (Isaiah 40:22).
    He also ridicules their efforts.
    “He that sitteth in the heavens shall laugh; the Lord shall have them in derision” (Psalm 2:4).
    All their so-called engineering is an exercise in futility and a waste of money.

  8. Bill:
    “You’re a sick killer monkey, Peter. Get your head read.”

    He/she is obviously a troll and has successfully ‘ruffled your feathers’.
    Best response for them is to IGNORE them. That NON-response irritates them more than any comment, no matter how appropriate or ‘witty’, you might offer as a ‘rebuttal’.

  9. “Note: The Trump administration has largely begun dismantling the Environmental Protection Agency mainly due to the Net Zero and global warming hoaxes”

    Oh yes of course, we mustn’t forget: this is only the first step. (To keep his duped, sycophantic fan’s attention focussed away from far more pressing issues and real threats, he’ll mainly ignore and/or sweep under the rug, or, simply SAY that he’ll address but will conveniently forget about).
    So, don’t worry: After ‘dismantling’ the EPA and the Net Zero & global warming hoaxes (if Trump and his Zionist administration ever does), the great orange, Zionist KING and his wonderful ‘White Hats’ are coming to save us all!
    With more false flag events, more psyops, concentrated martial law, mass staged shootings, the ‘Crypto crash’, fake government shutdowns, and everything else he’s talked about and in some instances, actually done: including his terrorist Venezuela coup and its fake excuse for fighting (CIA planted) drug cartels. Not forgetting, more WWIII threats and his latest pet: his new ‘Operation DIGITAL Warp Speed’ and other new tyrannical policies supposedly to protect us from more (fabricated) threats while the biggest REAL threat: total AI control & mass surveillance, with complete digitization of society; moves forward in leaps & bounds; of which none of his mesmerized worshippers seem aware of, nor even care much about, if they are.

    Altogether now:
    YAY Trump!

  10. Good. America should launch its nukes and bring about a nuclear winter. That way, all domesticated city dwelling cis white colonizers will starve and die, while the traditional black hunters and gatherers will survive. Return to monkey.
