Every claim below was made in this piece, quoted word for word and numbered in the order the piece makes them, so you can read it there rather than take our word for it. The sentence above each quote is our reading of the claim, not their wording. Each quote was checked against a stored copy of the page at build time; where the two differ, the quote is the fact.
Their wordsBut broadly speaking we expect atmospheric CO2 to keep growing until we cut emissions pretty substantially (e.g. to <50% of current levels).
Our reading
Atmospheric CO2 concentration is a lagging indicator of emissions trends, not a leading one.
Their wordsEither way, atmospheric CO2 is better seen as a lagging rather than leading indicator of changes in emissions, as it is harder to see the effects of emissions reductions on concentrations over shorter time periods.
Their wordsThat being said, we still expect some weakening of carbon sinks in a warmer world - something we have started to see in the data.
