carbon

Kolankiewicz, for one, was fascinated by studies of the carbon legacy of families — the emerging notion that a person’s carbon footprint would multiply through generations and that the best way to reduce emissions was to have one less child.

It got him thinking about the inverse: Could he quantify how much carbon increased with that extra child?

His answer helped the Tanton organizations reframe immigration squarely in global warming terms: Newcomers to the United States were making climate change worse, because as they increased their consumption here, their carbon emissions would increase, too.

Dorset Police, who previously said carbon monoxide poisoning was a possible cause, said the deaths were still being treated as "unexplained".

The sub’s hull was also made out of carbon fibre, an unconventional material for a deep-sea vessel.
