It is a well known fact that dust and sulphuric acid in the stratosphere have a cool down effect on earth.
These days, spring is taking a lot longer to arrive, and this is happening nearly everywhere in the Northern hemisphere.
6 weeks ago a 10000 ton meteorite hit the atmosphere and must have released a lot of dust. This was a stone meteorite, chondrite type, it must have contained a lot of sulphuric compounds. The meteor disintegrated mainly in the stratosphere.
Could it be that one and the other are somehow connected?
This very large stratospheric injection resulted in a reduction in the normal amount of sunlight reaching the Earth’s surface by roughly 10% (see figure). This led to a decrease in northern hemisphere average temperatures of 0.5–0.6 °C (0.9–1.1 °F) and a global fall of about 0.4 °C (0.7 °F). At the same time, the temperature in the stratosphere rose to several degrees higher than normal, due to absorption of radiation by the aerosol. The stratospheric cloud from the eruption persisted in the atmosphere for three years after the eruption.
Have a great Easter Monday!
