[Stoves] Stoves Digest, Vol 29, Issue 17

Crispin: 

1. I don't get your point. Two sentences after the Romm statement you quote (below), Tami says: 

" Mitigating black carbon is good for curbing short-term climate change, but to really solve the long-term climate problem, carbon dioxide emissions must also be reduced,” 

What is the difference between the Romm and Bond statements? 

2. Can you also give a cite for your claim (which I think is refuted by Tami's report - such as Fig.3.3): 

" The great majority of BC is not human in origin ..." 

3. My view is that paying more attention to BC will help with stove development - especially char-making stoves with their much reduced particulate release. Tami has made a much stronger case than "bad publicity"- and Joe Romm seems to me to have caught the importance of this by also bringing in BC's health aspect as well as " reducing regional climate change" .

Dear Amanda 



Like several other bloggers, Romm seems to misunderstand the difference between forcing and warming. 



“This demonstrates that curbing black carbon emissions could have significant impact on reducing regional climate change while having a positive impact on human health. ” 



The great majority of BC is not human in origin so any ‘impact’ would be on health, if we choose to have some impact. As work progresses on defining the health impacts of ultra-fine particles from cooking fires, we will have the attention of a larger audience than before. As they say, there is no such thing as bad publicity. 



For a healthier world… 

Crispin 




Thanks Crispin. 





Here is an excellent summary of the article by Joe Romm on Climate Progress:

Dear Friends 



A new and I would say major major paper on the atmospheric impact of black 
carbon particles is available for download. We know at least two of the 
authors here on 'Stoves'. Profs Tami Bond and Philip Hopke (the aethalometer 
builder who said he was a minor contributor) are frequent contributors on 
the subject of emissions testing. 



The paper is important because it is the first really detailed examination 
of the effects of atmospheric heating by Black Carbon (BC). 



The abstract is at 
< http://onlinelibrary.wiley.com/doi/10.1002/jgrd.50171/abstract > 
http://onlinelibrary.wiley.com/doi/10.1002/jgrd.50171/abstract and the paper 
is at 

< http://onlinelibrary.wiley.com/doi/10.1002/jgrd.50171/pdf > 
http://onlinelibrary.wiley.com/doi/10.1002/jgrd.50171/pdf 



It is not behind a paywall but it is large (40 MB). Times to get your hands 
dirty with BC! 



Regards 

Crispin
