摘要: In the 2015 UNFCCC Paris Agreement, article 2 expresses target of “Holding increase in global temperature to well below °C above pre-industrial levels and pursuing efforts limit 1.5 … recognizing that this would significantly reduce risks impacts climate change”1. Different interpretations precise meaning phrases ‘increase temperature’2 ‘pre-industrial’3 could have large effects on mitigation requirements corresponding social, policy political responses. Here we suggest current mean surface warming since times are higher than those derived by Millar et al. been calculated using alternative, but equally valid, assumptions as ones made authors.
