    China faces challenges in reaching its carbon neutrality goal by the year 2060 to meet the Paris Agreement and improving air quality simultaneously. Dramatic nitrogen emission reductions will be brought by this ambitious target, yet their impact on the natural ecosystem is not clear. Here, by combining two atmospheric chemistry models and two process-based terrestrial ecosystem models constrained using nationwide measurements, we show that atmospheric nitrogen deposition in China’s terrestrial land will decrease by 44–57% following two emission control scenarios including one aiming at carbon neutrality. They consequently result in a pronounced shrinkage in terrestrial net ecosystem production, by 11–20% depending on models and emission scenarios. Our results indicate that the nitrogen emission reductions accompanying decarbonization would undermine natural carbon sinks and in turn set back progress toward carbon neutrality. This unintended impact calls for great concern about the trade-offs between nitrogen management and carbon neutrality.

  2. Where Dust Comes From: Global Assessment of Dust Source Attributions With AeroCom Models

    The source of dust in the global atmosphere is an important factor to better understand the role of dust aerosols in the climate system. However, it is a difficult task to attribute the airborne dust over the remote land and ocean regions to their origins since dust from various sources are mixed during long-range transport. Recently, a multi-model experiment, namely the AeroCom-III Dust Source Attribution (DUSA), has been conducted to estimate the relative contribution of dust in various locations from different sources with tagged simulations from seven participating global models. The BASE run and a series of runs with nine tagged regions were made to estimate the contribution of dust emitted in East- and West-Africa, Middle East, Central- and East-Asia, North America, the Southern Hemisphere, and the prominent dust hot spots of the Bodélé and Taklimakan Deserts. The models generally agree in large scale mean dust distributions, however models show large diversity in dust source attribution. The inter-model differences are significant with the global model dust diversity in 30%–50%, but the differences in regional and seasonal scales are even larger. The multi-model analysis estimates that North Africa contributes 60% of global atmospheric dust loading, followed by Middle East and Central Asia sources (24%). Southern hemispheric sources account for 10% of global dust loading, however it contributes more than 70% of dust over the Southern Hemisphere. The study provides quantitative estimates of the impact of dust emitted from different source regions on the globe and various receptor regions including remote land, ocean, and the polar regions synthesized from the seven models.

    地球温暖化の将来予測モデルでは、観測された北極域での温暖化傾向が過小評価され、一方、温暖化が不明瞭な南極域でその傾向が過大評価されるという、対照的な両極の気温バイアスがある。この一因として、極域の雲の再現性の問題が考えられる。地球表層のエネルギー収支に主要な寄与をする日射量と長波放射量は、雲の相状態(水雲か氷雲か)に強く依存する。雲の相状態は環境場と雲の核となるエアロゾルの組成で決まるが、近年、エアロゾルの供給過程が温暖化の影響で変化している。本研究では、両極の下層雲の形成環境に特化した観測を実施し、先進的な気候モデルの改良を通じて両極の気温バイアスの問題を追究し、気候予測の精緻化に貢献する。

    大気中の微粒子は、雲の氷晶の核(氷晶核)として働き、雲の放射収支などを変化させる。しかし、この過程についての科学的な知見は限られており、気候変動予測において大きな不確定要素となっている。この過程を解明するため、本研究では氷晶核に着目した新たな気候モデルを開発し、大気中の氷晶核の空間分布の推定を高度化する。そして、氷晶核が雲の放射収支などに与える気候影響の推定精度を向上させる。
