There's undoubtedly papers about the negative impacts of commercial biofuels (distinct from biofuel from organic waste) - Jack has posted a few useful references. The things which are so absurd about Tim constantly posting these claims are:
> He is consistently and deliberately ignoring the fact that even within the
same type of hunger-causation (inefficient use of agricultural land), feeding cars is still only the second-biggest issue after feeding cows and other farm animals. His constant 'outrage' about the lesser of these is obviously nothing more than expression of his rabid anti-scientific ideology.
> Tim consistently and deliberately ignores the fact that this has everything to do with political expediency and business interests, and nothing to do with fighting climate change. I've pointed that out to him as early as 2014, citing prominent environmentalist George Monbiot's articles
published in the Guardian in 2004! The fact is even noted in the links Jack has provided: "
evidence from real production data, and new analyses bear out what many scientists have been saying: most if not all biofuels offer no savings in energy or carbon emissions, especially when indirect emissions from deforestation and other land use changes are taken into account, as they should be." And from another of the links, "
Not only do the land use changes (shifting crops from food and feed to fuel) escalate greenhouse gas emissions, but the fertilizers required to grow industrial biofuels release nitrous oxides, which are 300 times more powerful as a greenhouse gas compared to carbon dioxide." (Obviously, feeding cows is pretty bad for global emissions too :lol: )
> But most obviously and pathetically, Tim's constant claim that "tens of millions" of people die each year from this is blatantly is utterly false; for example
the paper in the WUWT link posted by Jack suggests a figure of
192,000 per year. And when I say that Tim posts this barefaced lie constantly, I mean constantly; I posted a couple of examples from 2014 above, and here's a few more recent examples, most or all of which were called out (especially by Deuce, trooper that he is):
November 2015: "
Tens of millions of people are dying each year due to this."
January 2016: "
Tens of millions per year die today as they have been for 20 years or so due to this green crap"
January 2016: "
I think there are many times the tens of millions of extra deaths than the 10 million per year due to the use of food as fuel"
March 2016: "
10 million people per year at least die due to lack of food due to it's use as fuel."
June 2016: "
we are killing 10 million plus each year today by using food as fuel."
The fact that he also occasionally tries to slander folk on the forum for allegedly not caring and even supposed complicity in this politically expedient/business scheme whose consequences he's chosen to multiply a hundred-fold in his imagination is merely the cherry on the cake here :lol:
