Provide fulsome scientific elucidation behind sun blocking

Rejected 17 signatures

What the petition asks

Cooling a portion of atmosphere the size of the UK will draw an equivalent mass of southerly warmer air to the UK and conversely a mass of cooler air from the UK to warmer countries, as temperatures equalise. This creates the potential for an extreme weather event, typically hurricanes and flooding.
What thought has the government given to the following?
What will less Sun have on the nation’s physical and mental health? (eg vitamin D and rickets, depression, family cohesion).
How will this effects crop production in the UK and adjacent countries?
Has the UK consulted other countries?
Is the UK government prepared to pay reparation damages?
What are the names of all those proposing and implementing the idea?
