Hello. I would like to know why the links between geo-engineering, solar radiation management, arosol spraying and global climate change; such as extreme weather, droughts, flooding, fires etc. are not being ackowledged and discussed by your self as well as the mainstream media? Many of us are aware that climate change is a intentional UN global agenda. The violent and destructive changes to global climate is an act of war. Please inform me how it is that you do not ackowledge these facts in you research?

Dear Debra,

The debate on geo-engineering as a possible response to climate change (which would include solar radiation management (such as aerosol spraying) and also carbon capture and storage/CCS) is on-going. It has to some degree been discussed in policy fora but has mainly been confined to scientific studies and research. The reason for this is at the relevant geo-engineering technologies and techniques have never really left the drawing board and practical geo-engineering solutions to climate change are yet to be found. Therefore, no large-scale geo-engineering measures to mitigate the effects of climate have been adopted and I am personally sceptical if this will ever happen.

Taking the example of CCS, it is not technically feasible to burn an amount of coal and use the energy extracted from that process to capture and compress the resultant CO2 into a volume that is comparable to the volume of the original coal. You can only compress the CO2 down to the order of ten times the original coal volume until it liquefies and you hit a compression “wall” – making CCS for coal unsustainable in terms of volume/storage use (as the captured CO2 has to be actually stored somewhere).

Another problem with considering geo-engineering as a solution to climate change is that it assumes that the effects of having too high concentrations of greenhouse gases in the atmosphere can somehow be linearly addressed by altering some external variable (in this case the influx of solar radiation). However, the global environment does not behave in a linear fashion. Solar radiation management may very well have some positive effects in reducing global warming, but will also result in additional problems such as a globally changed radiation profile with impacts on biological processes, chemical pollution caused by the aerosols used, and so on. Such a “solution” to climate change is certain to cause new environmental challenges.

These are two reasons that geo-engineering has not been acknowledged as a solution to climate change and discussed in-depth by UN Environment and the mainstream media. Instead, the reduction of greenhouse gas emissions remains the focus of climate change action.

Kind regards,
Gustav
