Biogenic Snow


The cliche would have it that you couldn't make this stuff up, but of course you could. But people wouldn't believe you.

"...recently found evidence that rain-making bacteria are widely distributed in the atmosphere...This is important because the formation of ice in clouds is required for snow and most rainfall. Dust and soot particles can serve as ice nuclei, but biological ice nuclei are capable of catalyzing freezing at much warmer temperatures."

So, maybe bugs make snow. Cool. Full article here.


The SnowBlog is one of the oldest publishing blogs, started in 2003, and it's been through various content management systems over the years. A 2005 techno-blunder meant we lost the early years, but the archives you're reading now go all the way back to 2005.

Many of the older posts in our blog archive suffer from link rot. Apologies if you see missing links and images: let us know if you'd like us to find any in particular.
