are there ways in which we might be affecting climate?
well yes but these are only now being discussed in the mainstream media and they are saying that they might deploy them to....you guessed it....'fight climate change'!!!
so its not like they have already been messing with the climate? uh huh....ok whatever...this is how they are going to make it legit:
Controversial plan to artificially cool the planet by firing aerosols into the atmosphere might NOT be as risky as thought, experts claim
Some scientists have proposed using aerosols to reflect radiation and cool Earth
But, a study earlier this year claimed it could backfire by making warming worse
If the technique were abruptly stopped, it would cause warming at faster rate
Scientists now say that this worst-case scenario, while scary, is not very likely

As the world grapples with different strategies to mitigate the warming climate, few have sparked such controversy in recent times as solar geoengineering.
The proposed plan would use aerosols, fired into the stratosphere with high-flying aircraft, to cool the planet by blocking radiation from the sun.
It would essentially mimic the effects seen after volcanic eruptions – but, an analysis published at the beginning of this year warned that the approach could have grave consequences.
If the plan to artificially cool Earth were abruptly stopped, the experts warned it could trigger extreme warming at rates far more dramatic than the current climate is changing, in a phenomenon known as the ‘termination shock.’
But now, some scientists have hit back, arguing that the risk might not be as it seems.
In a new paper published to the journal Earth’s Future, a pair of researchers from the Institute for Advanced Sustainability Studies in Potsdam, Germany and the John A Paulson School of Engineering and Applied Sciences at Harvard University explain that the current analyses focus on the worst-case scenario.
And, while termination shock would be catastrophic, it could mostly be avoided by taking a few simple precautions.
‘Most studies so far have focused on the extremes, like in a large-scale deployment that’s ended instantly and permanently,’ explains co-author Peter Irvine, of Harvard’s engineering school, in a video about the work.
‘If solar geoengineering were deployed at small scales, say cooling only a few tenths of a degree Celsius, then if it were ended there wouldn’t be substantial warming.
‘If it were phased out over the course of decades, there would not be a rapid warming, so that would also not constitute a termination shock.
‘And if it were turned off for some reason and then turned back on again, the termination shock could be avoided.’
Aerosols will remain in the stratosphere for months after their deployment has ended, giving a large window of time to restart the process before the shock takes hold, the researcher notes.
