A fascinating report on how CO2 might be trapped in the soil. Given the complexity of the subject, the lack of depth detracts from an otherwise important piece of journalism.

The story references Hansen as the sole climate expert, and he merely defends the notion of global warming. No expert opines on the biochar technology. Two investors are mentioned who appear to have an interest in global warming, but little information about their motivation to pursue this trial is given. This is interesting, if average, reporting.

An interesting report on a new/old technique for sequestering carbon dioxide in soil. Thus removing CO2 from the atmosphere and at the same time improving the quality of the soil the article states. Not very long or detailed but a good overview.

The article is short note about the concept of burying charcoal in the ground. There is not much info presented on the costs or efficacy of the idea, nor schemes to do it at an individual level. Hansen is invoked correctly as advocating reducing atmospheric carbon dioxide, but the article implies he endorses the biochar scheme, but does not state that, which seems a little slippery of the author.

An extremely well-written story that spotlights what might well become a practical solution to the build-up of carbon dioxide in the Earth's atmosphere. Very clear presentation--one leaves with new information and a sense that this is something that might actually be doable.

This isn't a review of the article; it's a comment on our reviews. Our biases are more evident in this subject than in politics. Maybe it's a problem that should be addressed by NewsTrust staff. I don't know how to overcome it, but the first step would seem to be to recognize it in ourselves.

Interesting short case study about using a method of the past to do a present job. It's the kind of advocating article, under the tone of high probability, with no skeptical opinion attached to it, but this doesn't make it unreliable and it's worth reading all the same.

Old hat

Good as far as it goes but leaves a misconception

A well written story that has to inform a lot of people like me who have never heard of this process.

Unfortunately the information on www.biochar-international.org does not agree with the rosy picture in this article. One would have to collect all the agricultural waste from the whole world, process it and bury it and then only have a small effect, offsetting only a modest percentage of carbon emissions, not counting all the fuel burned to do the collection. There is nothing practical about this except maybe the Europeans can be conned into paying people to do this.

Subject of reversing global warming of which is of extreme importance and a very practical way to address global warming.
