As for Pinatubo, WW, it was shown to decrease temps by close to 1% world-wide.
Water is a chemical substance with the chemical formula H2O. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state, water vapor or steam.
Water plays an important role as a chemical substance. Its many important functions include being a good solvent for dissolving many solids, serving as an excellent coolant both mechanically and biologically, and acting as a reactant in many chemical reactions. Blood, sweat and tears... all solutions of water.
You probably know water's chemical description is H2O.
It would depend on your definition of a chemical.
A chemical is: "a substance produced by or used in a chemical process."
And, water is a chemical because it is be used in chemical reactions such as neutralization, redox, etc.
I believe what you're asking though is if water is a chemical substance: "a material with a definite chemical composition."
Water is also a chemical composition because of its electron configuration in its valence shell which defines its chemical properties.

The more spectacular sunrises and sunsets and the bluer skies will be non-economic “collateral benefits.”
Despite years of speculation and vague talk, peer-reviewed research on geoengineering is remarkably scarce. Nearly the entire community of geoengineering scientists could fit comfortably in a single university seminar room, and the entire scientific literature on the subject could be read during the course of a transatlantic flight. Geoengineering continues to be considered a fringe topic.
Many scientists have been reluctant to raise the issue for fear that it might create a moral hazard: encouraging governments to deploy geoengineering rather than invest in cutting emissions. Indeed, geoengineering ventures will be viewed with particular suspicion if the nations funding geoengineering research are not also investing in dramatically reducing their emissions of carbon dioxide and other greenhouse gases. Many scientists also rightly fear that grants for geoengineering research would be subtracted from the existing funds for urgently needed climate-science research and carbon-abatement technologies. But there is a pressing need for a better understanding of geoengineering, rooted in theoretical studies and empirical field measurements. The subject also requires the talents of engineers, few of whom have joined the small group of scientists studying these techniques.
The modern concept of geoengineering (or climate engineering) is usually taken to mean proposals to deliberately manipulate the Earth's climate to counteract the effects of global warming from greenhouse gas emissions.

Geoengineering has been rampant for years...
Its not a small thing Phage...
Look at the Olympics in China, they openly admitted to it...
Not to mention, we only hear part of what they do..
Gimmie a break!!!
And BTW, in what context should I take "in the closet"???
To me thats always meant hidden..Whats your definition??
