ask your public officials to simply free the market to bids against your public utility providers who currently nationwide have a lock on energy markets to simply bring down these costs….think of green energy that not only helps you pay off your technology you invest in but actually helps cut costs from federal state county and city revenues and taxes…its 2.5 trillion dollars a year nationwide at the federal level alone…that would pay of the deficit of this country very fast while also freeing up markets providing jobs for new technology and all the instalation and small contracting jobs that would come back acrossed this country…why stay slaves to debt and taxes that are being waisted to keep unworhty public officials and some persons gaited community home lifestyl at the expense of smart governing on behalf of the citizens of the United States of America

We should plant more trees and cut down a lot fewer trees. We need the trees to help with carbon sequestration and to help stabalize the soil. We should also switch to hydrogen powered vehicles, all-electric powered vehicles, and hybird hydrogen-electric powered vehicles. Solar power could be used to manufacture hydrogen and to recharge electric batteries. While with hydrogen-electric hybird vehicles, the hydrogen cell will recharge the electric batteries in the field when and where needed without having to take the vehicle out of service. Best wishes, Michael E. Bailey.

Realmente interesante el artículo sobre la Geoingeniería, siempre he pensado que la Ciencia no puede ser inparcial; la verdadera Ciencia es PARCIAL, está a favor de la Humanidad, del progreso Social, de una mejor calidad de Vida, sin embargo, siempre es necesario distiguir la diferncia que existe entre la Ciencia como tal y las técnicas utilizadas para explotar en beneficio de unos cuantos los descubrimientos científicos. No hay que temer al cambio, ni a los nuevos descubrimientos, lo que hay que hacer es DEMOCRATIZAR LA CIENCIA, que sea para todos
No creo en verdades absolutas, es más, siempre que pensamos que hemos llegado a una solución definitiva, se detiene el progreso
Felicidades a los Geoingenieros ¡sigan adelante por el bien de todos!
¡SI SE PUEDE!

Dr. Karn, it’s apparent this planet needs much skills to maintain it. However, the universe has much planet. And so we need also much professionals to explore the earth and other the billion planets which continuously birth. Wow, in the future, I hope our greatgrand-grand children to become Marsgeoengineerings, Yupiter lawyers, etc… And so, I think, we need genealogyengineering for them…..!!!!

In my opinion DO NOT TOUCH THE SEA (fertilizing the ocean), please come to your sences instead of thinking crazy things like sending back the efects of the sun, PLEASE !!
The answer is reforestation of the planet, PLANT TREES ALL OVER THE WORLD IF YOU CAN, please stop being silly.
Plant trees mainly in Africa where the tornadoes begin that is the answer to the problem of the ecosystem. Do not polute more the sea we have enough already. No trees no clouds, seed the ground and go up; come to your sences.
Do not keep on poluting the sea by droping into it all the drains from the cities mainly dangerous waste.
