Soil carbon is important but it is staggering that both Minette Batters and Prince Charles have made unchallenged statements on @BBCr4today : That some farms are already carbon neutral and that soils could take up 70% of the world's emissions 1/
This is all in an effort to promote sustainable livestock farming. Like Graham Harvey in his book ‘Grass-Fed Nation’ they have been seduced by the claims of Allan Savory; but these have been thoroughly debunked by the Food Climate Research Network

The fallacy rests on a confusion between fast and slow carbon cycles, between carbon stocks and flows, which with a little bit of naive maths creates a myth that now permeates the NFU’s PR on the future of farming. We need better soil health to stop carbon release … 3/
But it is no good using this as a ploy to retain high levels of meat consumption; and we need a massive reduction in the consumption trend. Good soil health will help have sustainable arable farming, but not as a silver bullet to cancel our fossil fuel emissions 4/
Livestock reduce the efficiency of calories produced per hectare (Cassidy et al Environ. Res. Lett. 8 (2013)) in addition, livestock makes a high and increasing contribution to our carbon emissions (Godfray et al., Science 361, eaam5324 (2018)). 5/
It is such a shame that the NFU are promulgating junk science to advance their meat-first agenda, and it seems that Prince Charles is also on board. 6/6

@mskathleenquinn I have never made it there and maybe never will, but nuclear weapons changed my life in different way. In 1981, Professor Mike Pentz, who led the formation of the OU science department, founded Scientists Against Nuclear Arms (SANA). I was at Bristol Uni. doing a Post Doc. 1/
@mskathleenquinn I went to hear him speak. What an amazing speaker he was; I signed up on the spot. Within a months it seemed I was on the National Coordinating Committee. It kind of killed my passion for science, something I'd been in love with since a young boy. I left research 2/
@mskathleenquinn I went into the world of industry and in my spare time spent a lot of the 80s working in the background helping to develop tools for the anti-nuclear movement (like a Program to assess impact of nuclear attacks run on an Amstrad PCW 8256, given free to local authorities). 3/

@pmbbiggsy @RHarrabin @James_BG @ECIU_UK @CraigBennett3 @tom_burke_47 @CarbonBrief @hmtreasury Some people really need to 'keep up' ...
Climate Models all began with Newton, with other branches entering the fray as science emerged in succeeding 300 years (incomplete list)

1728 - Newton’s Principia published in English (discrete mechanics) 1/
@pmbbiggsy @RHarrabin @James_BG @ECIU_UK @CraigBennett3 @tom_burke_47 @CarbonBrief @hmtreasury 1738 - Daniel Bernoulli publishes “Hydrodynamics” (continuous mechanics)
1757 - Euler publishes partial differential equations that apply to fluids
1800 - Herschel discovers ‘radiant heat’ in spectrum
1827 - Fourier published paper proposing what we now call greenhouse effect 2/
@pmbbiggsy @RHarrabin @James_BG @ECIU_UK @CraigBennett3 @tom_burke_47 @CarbonBrief @hmtreasury 1836 - Agassiz coins term “Ice Ages”
1840 - Navier-Stokes equations publ’d (extending Euler), ubiquitous in fluid dynamics, utility beyond doubt and btw used in climate models
1850 - Alexander von Humboldt publishes ‘Views of Nature’ 3/

@RHarrabin @GSmeeton @Policy_Connect Roger, did you really imply today on @BBCNews bbc.co.uk/sounds/play/m0… that heat pumps "were not very well developed"? The sadly departed Prof. David Mackay wrote in 2009 "heat pumps are already widely used in continental Europe, but strangely rare in Britain.” … I wonder why? 1/
@RHarrabin @GSmeeton @Policy_Connect @BBCNews He continued to explain that if you took the gas used in a home boiler, sent it to a gas fired power station then used the electricity to run a heat pump, the heat pump would be more efficient and hence lower in carbon foot print, p. 151:- 2/
@RHarrabin @GSmeeton @Policy_Connect @BBCNews It is frankly infuriating that not only you but also @theCCCuk are talking up hydrogen as a fuel when air-sourced heat pumps (note: not just ground sourced btw) are a proven, available technology. I wrote about it here essaysconcerning.com/2019/09/07/ren… 3/3

@James_BG Why do you not mention Heat Pumps Kames. This is crazy. HPs worked during beast from east if sized properly. Are we really going to have a H2 n/w (by 2030?!) to deal with treble beast from east? It's very simple: rollout HPs NOW, and aggressively decarbonise electricity. 1/
@James_BG It is troubling that the ignorance about Heat Pumps is so widespread, extending to BBC. It is tech. available now, and Prof. Mackay deserves a re-read for those who don't understand them. Here's an essay on myths re. Solar PV and Heat Pumps. essaysconcerning.com/2019/09/07/ren… 2/
@James_BG Currently, domestic Energy Performance Certificates (EPCs) contain a bug because they NEVER recommend a Heat Pump even though evidence shows it works. We do not need gas or H2 as backup. In Sweden or Yorkshire!! Evidence: yorkshireenergysystems.co.uk/epcandheatpump… 3/3

@BBCScienceNews @MattMcGrathBBC As @Peters_Glen points out in kleinmanenergy.upenn.edu/energy-policy-… the first priority is emissions reductions. DAC (Direct Air Capture) powered by renewables has potential but the framing by Carbon Engineering / BBC on capturing carbon to create fuel is problematic on several levels. 1/n
@BBCScienceNews @MattMcGrathBBC @Peters_Glen Firstly, Road, Rail & Shipping even, being electrified making fuel redundant; and in a competing hydrogen economy with fuel, it would be non-carbon based one. Leaving Aviation: 13% of transport and just 3% of all sector global emissions. DAC focused on that no silver bullet. 2/n
@BBCScienceNews @MattMcGrathBBC @Peters_Glen Secondly, in terms of Govt financing, would we focus that on decarbonising road, or decarbonising aviation? DAC may be great to invest some $ in as Devt phase tech, but big $$$ need immediately in road sector. Not either / or in terms of end state, timing wise sorry it is. 3/n
