Listened to Climate Obscura by Brooke Gladstone and Bob Garfield from On the Media | WNYC Studios

Trump's attacks on climate science; the dark money behind environmental deregulation; and the Anthropocene.

The Trump administration has ordered federal agencies to stop publishing worst-case scenario projections of climate change. This week, On the Media examines the administration’s pattern of attacks on climate science. Plus, a look at the dark money behind environmental deregulation.

1. Kate Aronoff [@KateAronoff], fellow at the Type Media Center, on the White House's suppression of climate warnings. Listen.

2. Jane Mayer [@JaneMayerNYer], staff writer at The New Yorker and author of Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right, on the billionaires supporting the modern conservative intellectual framework. Listen.

3. Jan Zalasiewicz, Anthropocene Working Group Chair, on the traces that today's humans might leave behind for future civilizations, and Benjamin Kunkel [@kunktation] on whether the Age of Capitalism might be a more appropriate term to describe our epoch. Listen.

Some interesting discussion on climate, but more specifically on the effects of man from a much longer term geological perspective. It’s not often that one could say there’s news that takes a Big History perspective, but this certainly comes as close as one could hope. The second segment was particularly interesting.

I sort of like the idea of dating the Anthropocene from the 1950’s with the invention of the atomic bomb as it created a world-wide layer. But then the beginning of agriculture or the start of the industrial revolution also likely had world-wide effects as well.

Collective learning has potentially been growing at the expense of a shrinking body of diverse language

Big History may indicate why we're losing diversity in the number of languages on Earth.

Yesterday, I saw an interesting linguistic exercise:

Short activity to show how flexible our language is and how difficult collective learning would have been for our non sapiens ancestors.

Step 1: As a class, choose 200 random words. (I had 15 kids choose 14 words each)

Step 2: Answer the following questions using only the words listed:

  1. How should we try to kill that mammoth?
  2. Explain why you should marry me.
  3. Give directions for a simple task.
  4. Come up with a plan to improve our cave.
  5. Describe a physical landscape.
  6. Come up with your own question!

I have to imagine that once the conceptualization of language and some basic grammar existed, word generation was a much more common thing than it is now. It’s only been since the time of Noah Webster that humans have been actively standardizing things like spelling. If we can use Papua New Guinea as a model of pre-agrarian society and consider that almost 12% of extant languages on the Earth are spoken in an area about the size of Texas (and with about 1/5th the population of Texas too), then modern societies are actually severely limiting language (creation, growth, diversity, creativity, etc.) [cross reference: A World of Languages – and How Many Speak Them (Infographic)]

Consider that the current extinction of languages is about one every 14 weeks, which puts us on a course to loose about half of the 7,100 languages on the planet right now before the end of the century. Collective learning has potentially been growing at the expense of a shrinking body of diverse language! In the paper “Global distribution and drivers of language extinction risk” the authors indicate that of all the variables tested, economic growth was most strongly linked to language loss.

To help put this exercise into perspective, we can look at the corpus of extant written Latin (a technically dead language):

“It is a truly impressive fact that, simply by knowing that if one can memorize and master about 250 words in Latin, it will allow them to read and understand 50% of most written Latin. Further, knowledge of 1,500 Latin words will put one at the 80% level of vocabulary mastery for most texts. Mastering even a very small list of vocabulary allows one to read a large variety of texts very comfortably.”

These numbers become even smaller when considering ancient Greek texts.

Another interesting measurement is the vocabulary of a modern 2 year old who typically has a 50-75 word vocabulary while a 4 year old has 250-500 words, which is about the level of the exercise.

As a contrast, consider the message in this TED Youth Talk from last year by Erin McKean, which students should be able to relate to:

And of course, there’s the dog Chaser, which 60 minutes recently reported has a vocabulary of over 1,000 words. (Are we now destroying variants of “dog language” for English too?!)

Hopefully the evolutionary value of the loss of the multiple languages will be more than balanced out by the power of collective learning in the long run.
