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?

I remember  the eruption of  Mount Pinatubo releasing 17 megatons of SO2 in the stratosphere. For the effects on climate I quote wikipedia:

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).[7][24] 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!

  1. Everyone laughs at global warming. I take it seriously, at least, to the point that I believe all of these things are adding together to cause a lot of trouble in the future.

    • I really think there is indeed global warming. But local is not global. Everything together averages to a warming. global warming makes more weird weather possible …

  2. Interesting.

    I did notice a distinct difference this spring from last. It was cooler this year than last when we went to hike the same place we did almost a year to the day.

    last year March 28th

    thawed waterfalls, greening up of the foliage.

    this year March 29th


    still some frozen waterfalls and everything still slumbering.

  3. it’s a complex equation, no doubt about that. Sunspots increase the incoming energy, meteors and volcano’s increase the reflection — It’s hard enough predicting the weather tomorrow 🙂
