《科學報告》發表了一篇題為「A real-time Global Warming Index 」的研究論文。在該篇文章中,以英國牛津大學環境變化研究所的K. Haustein為首,來自多個機構的數位專家團隊提出了一個實時版本的變暖指數,以對造成全球變暖的人為因素進行評估。該指數彌補了Otto等提出的人為變暖指數在對內部變異的敏感性、自然或人為因素中的不確定性及其穩健性等方面缺乏全面評估的不足。
研究者們不僅提出了這一簡化的全球人為變暖實時指數,而且還評估了其在氣候強迫和短期氣候波動的不確定性方面的穩健性。該指數為穩定溫度目標提供了更好的科學背景,並有可能降低氣候政策的波動性。研究者們同時還對溫度觀測、氣候輻射強迫、內部變異以及模式反應這些因素引起的不確定性進行了量化。該指數和相關的人為變暖速率與其他一系列更複雜的方法一致,可以用來估計人類對可觀測到的全球氣溫變化所做出影響。
摘要:We propose a simple real-time index of global human-induced warming and assess its robustness to uncertainties in climate forcing and short-term climate fluctuations. This index provides improved scientific context for temperature stabilisation targets and has the potential to decrease the volatility of climate policy. We quantify uncertainties arising from temperature observations, climate radiative forcings, internal variability and the model response. Our index and the associated rate of human-induced warming is compatible with a range of other more sophisticated methods to estimate the human contribution to observed global temperature change.
