Foodbabe Fails – Blames Astroturfing

Many people are complaining that CNN, in reporting on the recent E. coli outbreak on romaine lettuce, had The Food Babe (Vani Hari) on as a food “expert.” This, of course, is a complete journalistic failure on the part of CNN. The Food Babe is a famously scientifically illiterate alarmist whose career is based on peddling misinformation. My favorite example is when she completely misunderstood the nature of pressure in airline cabins, and complained that the air was tainted with up to 50% nitrogen.

As important as this complete scientific failure, was her response. She did not transparently correct the misinformation and apologize. She simply deleted the post.

Hari has come under extensive criticism for spouting her nonsense and fearmongering. She is perhaps most famous for her “yoga mat” stunt, completely misunderstanding the fact that chemicals can be used for a variety of reasons, and that does not make them dangerous.

Her general response to criticism is to (in addition to hiding) go on the attack. She does not appear to be an honest broker of information, but rather a self-promoter who will attack her critics. She also likes to ban critics from her own page. So when the internet complained to CNN that the Food Babe was not an appropriate person to have on their program to be presented as an expert, Hari did what she does – she went on the attack.

Her tactic this time is to blame the whole affair on “astroturfing.” This is a real phenomenon in which an industry, company, cult, or ideological group will create the impression of a grassroots campaign using front organizations and paid agents. However, this isn’t the whole story.

Taking A Second Look at Hydrogen

Published by under Technology

There seems to be increasing awareness (and perhaps weakening denial) that we are standing at a critical moment in the history of our civilization. A problem has been looming for decades and we have largely ignored it. Now the effects are starting to be felt, and scientific confidence has only grown stronger over time.

I am talking, of course, about global climate change. There are still significant stragglers, but there is general consensus in the world that we need to urgently decarbonize our civilization. This is definitely one of the greatest challenges that our generation faces, and many suspect the future will judge us largely by how we meet this challenge.

Many groups have rolled up their sleeves, not to just advocate for one or another potential solution, but to chart viable pathways to a zero carbon infrastructure. The bad news is, it won’t be easy and it will cost trillions of dollars. The good news is, we already have the necessary technology and it will save many more trillions of dollars, not to mention disrupted and shortened lives.

A recent article in the Economist goes over the big picture, making a plug for a significant role of hydrogen. They make the good point that we can’t just think about power generation and cars, we have to also think about industry.
