Woodlands sow the seeds for clouds and rain 🌧️ 🤯

When clouds empty themselves some kilometers inland, they are exhausted and cease to exist. 

So, how on earth do we get rain much farther inland? After all, all the clouds that drift overland from a nearby sea are spent.

Well, forests are the main water transportation mechanism for clouds deeply overland.  Trees release a lot of water vapor, together with oxygen. They also inhale carbon dioxide, so when I walk in a forest and I in- and exhale I'm feeding the trees as much as they are feeding me.  

Now a new discovery show yet one more way in which woodlands can "seed" clouds 🤔 

In a paper published this month in Science Advances, Dada's team establishes a new heavy hitter in cloud creation: a kind of chemical released by trees. Trees emit natural volatiles like isoprene and monoterpenes, which can spark cloud-forming chemical reactions. Dada's new work focuses on an overlooked class of less abundant volatiles called sesquiterpenes, which smell woody, earthy, citrusy, or spicy, depending on the molecule and type of plant or microbe that emits them.
The team shows that sesquiterpenes are more effective than expected for seeding clouds. A mere 1-to-50 ratio of sesquiterpene to other volatiles doubledcloud formation.

Is This the Fourth Turning?

The broader concept that civilizations run in cycles is very old. In 146 BC, Polybius laid out the rough contours of the political cycle -- the"kyklos." 

Polybius' formula is actually better known than Strauss-Howe — you've seen it as the "Hard Times Create Strong Men" meme.

Volledig lichaam

Ik moet erbij vertellen dat ik, anders dan het gewone volk, veel gemakkelijker overprikkeld raak omdat mijn cognitieve vermogens anders zijn dan jullie, maar dat ik tegelijkertijd verveeld raak als ik weer niet genoeg geprikkeld word. Een meta-millennial, zou je kunnen betogen

Grappig hoe alle millennials zichzelf anders dan anderen vinden. 

Als je met diverse mensen praat ontdek je al snel dat iedereen min of meer hetzelfde is qua bouw. Het verschil zit hem er vooral in hoe het ermee omgaat.
