This week's research roundup includes 54 articles.

The most viscerally fascinating article in the present collection is undoubtedly Polag & Keppler's Global methane emissions from the human body: past, present and future.  Here we learn some unsettling facts: 

• Prediction of global CH4 emission for the year 2100 is 1221?±?672?Gg.

• Future CH4 emission by humans might be in the range of present permafrost soils.

• Future factor-weighted estimation of human CH4 emission exceeds unweighted estimation.

Combine the above quantification with what we know should be our diet leaning more toward such sustenance as cabbage and beans and we could be looking at an emergent positive feedback, an unexpected outcome of climate change mitigation.

Per popular demand we're attempting to categorize research according to broad classifications; to the extent possible research articles appear in sections having principally to do with the physical science of anthropogenic climate change, relationships between biological systems and climate change, and the  back and forth of human drivers and responses with respect to climate change. Some articles don't neatly classify— in this collection is an article linking algal growth with Greenland ice albedo, and another constraining coal-fired generation plant contributions to global carbon load but as an objective in improving climate model performance. Each was classified as a physical sciences item. 

Extraneous matter:

In the course of compiling this list we encounter the same effect as when searching pages of an encyclopedia or using Wikipedia: some diversions are just too good to ignore. The RSS feed principally supplying raw material for these posts is of course not perfect and so this week's trawl netted us an irresistible wrong species: The five deeps: The location and depth of the deepest place in each of the world's oceans. Answering the promise of the title turns out to be surprisingly complicated.
