Speaking of Al Gore - I'll give even odds that Gore (and his low IQ but passionate Hollywood fools) - seeded the upper atmosphere with lightweight reflective stuff to 'block out sunlight'.
If so, the stuff won't come down for decades. Volcanoes push stuff up but but the particles are heavy enough to come down in a few years.
Gore and his true believer fools would NOT make that 'mistake'. If we have cooling pattern for the next three years we should look into 'gore the environmental criminal...'
