@Lyndon - 

To me, this is about humility. Sometimes it can be difficult for experts to admit how much they don't know after spending decades researching a certain topic. In this case, there is a significant discovery related to the planets carbon cycle. A discovery that seems to be coming late in the game.

Other times, the people who know the most are the ones who speak the most cautiously.

It's astonishing to me that in 2017 we can be making these kinds of discoveries," said Simon Lewis, a professor at the University of Leeds in England

Did you see the NY Times article about peat's impact on climate? It's "Scientists Map Vast Peat Swamps, a Storehouse of Carbon, in Central Africa" from Jan 11th.



 

Thanks, Ariella, for posting this interesting article. I can imagine the salivation in C-suites of top energy industry corporations over the prospect of all that energy content just sitting there for the taking ...

The quoted statements seem to compare the peatland carbon with airborne fossil fuel emissions ... which is interesting, but it's not clear from the quoted material whether or how the peat (presumably, still accumulated on or in the ground) has an impact on the Earth's climate. Probably there are some emissions (e.g., decomposition gases), but that would be worth comparing with fossil fuel emissions, not the total mass of peat.

And the peat has lain there for 10K years. Global warming has escalated into a problem just within the last century or so, and is supposedly correlated with the intensification of fossil fuel emissions.

@impactnow I see a lot of claims being thrown around now in the political arena, and many people then retweet and repost without ever asking themselves, "Wait a minute, why am I sharing this assertion that 36K people will die without ACA if I don't know how that number is calculated?" I've asked a few people who have posted for the source and gotten nada. Given where that number has appeared before, I suspect it the number of deaths the CDC ascribed to flu, though NPR debunked that back in 2010.

@Lyndon_Henry Did you see the NY Times article about peat's impact on climate? It's "Scientists Map Vast Peat Swamps, a Storehouse of Carbon, in Central Africa" from Jan 11th.

The peat, which consists of slowly decomposing vegetation in swamp forests, has been accumulating for more than 10,000 years. As in all peatlands, the vegetation is a natural storehouse of carbon taken from the atmosphere — in this case, about 30 billion metric tons of carbon, or roughly equivalent to the carbon in two decades of fossil fuel emissions in the United States. [emphasis added]

"It's astonishing to me that in 2017 we can be making these kinds of discoveries," said Simon Lewis, a professor at the University of Leeds in England 

 

And given our focus here, I'll quote from later in the article:

The current study used satellite imaging and analysis to determine the extent of the peat, which is about 55,000 square miles. Field work across the wetlands — which Dr. Lewis said were the most difficult expeditions he had undertaken in 15 years of research in Africa — revealed the depth of the peat, up to 20 feet, allowing a calculation of the amount of stored carbon.

 I was also shocked at how many people believed fake news they never bothered to verify the information. Hearsay became fact and people made decisions based on it. If this trend does not stop we will find ourselves living in a country driven by erroneous data and decisions.



 

This discussion got me to wondering about other views on the fake news and related issues. I found this, which also has implications for data science ...

Given the choices, I also selected "Ensuring data quality and data trust". This relates to my views on the Fake News issue expressed in other A2 threads. I think societal respect for the reliability and validity of data and factual, verifiable information is eroding, and the growing confusion over true vs. false news/information is alarming. Data (and information) integrity should be a top priority. This includes inculcating understanding of how to judge what has integrity and what doesn't ...

Interesting that data integrity tops our list! Is this a reaction to the public data missteps we witnessed in 2016 or something else? Please say more!
