    Solar Geoengineering May Not Halt Ocean Warming, Study Says

    Releasing reflective aerosols into the stratosphere or using any other technique to reflect sunlight away from the earth may not halt sea level rise, according to a new study published in Nature Geoscience. Sea level rise is the biggest concern of climate scientists since 10% of the world's population lives less than 30 feet above sea level. Sea levels are expected to rise by 2.2 feet at the end of the century according to a recent NASA study published in the Proceedings of the National Academy of Sciences Feb 12, 2018.

    Details concerning the science can be found at the carbonbrief.org website. Reflecting sunlight away from the earth causes decreasing evaporation and that decreases rainfall in certain regions more than others, especially the North Atlantic region. That increases the salinity of that region, making the water denser and it sinks faster. This speeds up the Atlantic Meridional Overturning Circulation (AMOC). The AMOC transfers heat from the equator to the North Atlantic and faster AMOC will cause more warm water to be buried deep into the ocean. Marine ecosystems would not be protected with this approach.

    This is a very important study if it is correct because reflecting sunlight away from the earth was the most likely and discussed technique for
    geoengineering the climate in order to prevent a catastrophe. There are no good geoengineering ideas that I know of.

    Nature Geoscience? NASA? National Academy of Sciences? Carbonbrief.org?

    That's a lot of high-powered crazies.

    Who cares?
    Call your state legislators and insist they approve the Article V convention of States to propose amendments.


    I pledge allegiance to the Constitution as written and understood by this nation's founders, and to the Republic it created, an indivisible union of sovereign States, with liberty and justice for all.

    Solar fails again.

    It has been failing since the mid-1970's.

    Why would anyone want to halt natural processes?
    Freedom Requires Obstinance.

    We the People DID NOT vote in a majority Rodent Congress, they stole it via election fraud.

    The catastrophe based on models? The alarmism is designed to motivate but observed science keeps thwarting the alarmists.
    When Donald Trump said to protest “peacefully”, he meant violence.

    When he told protesters to “go home”, he meant stay for an insurrection.

    And when he told Brad Raffensperger to implement “whatever the correct legal remedy is”, he meant fraud.

    War is peace.

    Freedom is slavery.

    Ignorance is strength.

    Are you saying that earth's warming is natural? What is natural about it?

    There are obvious reasons why we would want to halt sea level rise or global warming if we could do it. We would also want to halt another ice age.

    The study published in the journal Nature, section Geoscience, used sulfate aerosols to counter 100% of the surface warming based on the IPCC's worst case scenaraio. The oceans did not warm

    as much as they would have without the sulfate aerosol injections under the same scenario. There are many problems with this method including: reduced rainfall in monsoon regions and a decline

    in crop yields, damage to the ozone layer, reduced solar energy from solar panels, acid rain, and unpredictable weather patterns. Calcium carbonate is another aerosol possibility that would not damage

    the ozone layer or produce acid rain. I don't know if it is possible to construct any type of solar reflecting technology that would not impact rainfall and still cool the earth. Probably not. I was

    wondering if this technology could be used to reduce the earth's mean global surface temperature by about 1 degree C. without having serious adverse effects, assuming we could prevent more

    than a 2.0 to 2.5 degree C. rise in global mean temp. above the pre-industrial level, bringing the total down to 1.0 to 1.5 degree C.
