Researchers collected cloud samples atop a mountain and found that about half of their ice crystals contained lead. Then, by building artificial clouds in laboratory chambers, the team determined that lead actually causes ice crystals to form.

Hmmm. And here I thought that ‘Spring was in the air’ this time of year. Turns out it’s just lead.
With how good our detection methods are, I'm surprised it is not 100% containing some lead.
Then, by building artificial clouds in laboratory chambers, the team determined that lead actually causes ice crystals to form.
How much lead is required to change the cloud formation? How large do the lead crystals have to be? How does that compare to the amounts found in natural ice crystals? Has cloud formation been reduced since the US largely abandoned leaded gas? Is aviation fuel still leaded and how does that affect contrail formation?
Lots of questions, just about none answered by the article.
