CLIMATE CHANGE SOLUTIONS
In the search for a solution to the climate change problem, geoengineering (injecting aerosol like sulphates into the stratosphere) is at the top of the list as an economically viable solution for countries to begin using.
Geoengineering works by forcing the sun’s radiation to bounce off of the aerosol sulphates, so the heat cannot reach the earth’s surface – therefore lowering global temperatures.
Once the aerosols are up in the stratosphere (7km to 50km in altitude), stratospheric winds do the rest of the work by carrying the particles across the globe.
However, climate scientists are now warning of the potential unintended consequences of this method, as this may have the opposite effect in certain parts of the world and may lead to severe flooding, or droughts as reported by Wired.
This method could also result in the world becoming entirely dependent on geoengineering for climate control in the future. This has climate scientists worried about the “band-aid” effect, mass extinction events and the negative impacts on food crops.
Further research is being conducted into the potential uses of microscopic seawater particles to brighten lower-hanging clouds, achieving the same effect as aerosol sulphates, as reported by Futurism.
This would be a more environmentally friendly option than aerosols.
It is also possible to colour the entirety of the earth’s atmosphere in a new colour (pink, green, red, yellow) using similar aerosol sulphates. But these would eventually be pushed away by the stratospheric winds as mentioned before, making the colour of the sky go back to normal.
