Anthropogenic contributions to slow warming over 1998-2012
Xuanming Su, Hideo Shiogama, Katsumasa Tanaka +6
The observed global mean surface temperature increase from 1998 to 2012 was slower than that since 1951. The relative contributions of all relevant factors including climate forcer…
SolarEV City Concept for Paris: A promising idea?
Paul Deroubaix, Takuro Kobashi, Léna Gurriaran +3
Urban decarbonization is one of the pillars for strategies to achieve carbon neutrality around the world. However, the current speed of urban decarbonization is insufficient to kee…
emIAM v1.0: an emulator for Integrated Assessment Models using marginal abatement cost curves
Weiwei Xiong, Katsumasa Tanaka, Philippe Ciais +2
We developed an emulator for Integrated Assessment Models (emIAM) based on a marginal abatement cost (MAC) curve approach. Using the output of IAMs in the ENGAGE Scenario Explorer…
Impact of lockdowns and winter temperatures on natural gas consumption in Europe
Philippe Ciais, François-Marie Bréon, Stijn Dellaert +11
As the COVID-19 virus spread over the world, governments restricted mobility to slow transmission. Public health measures had different intensities across European countries but al…
Paris Agreement requires substantial, broad, and sustained engagements beyond COVID-19 public stimulus packages
Katsumasa Tanaka, Christian Azar, Olivier Boucher +3
It has been claimed that COVID-19 public stimulus packages could be sufficient to meet the short-term energy investment needs to leverage a shift toward a pathway consistent with t…
Global Daily CO emissions for the year 2020
Zhu Liu, Zhu Deng, Philippe Ciais +25
The diurnal cycle CO emissions from fossil fuel combustion and cement production reflect seasonality, weather conditions, working days, and more recently the impact of the COVI…
De-carbonization of global energy use during the COVID-19 pandemic
Zhu Liu, Biqing Zhu, Philippe Ciais +15
The COVID-19 pandemic has disrupted human activities, leading to unprecedented decreases in both global energy demand and GHG emissions. Yet a little known that there is also a low…
Source attributions of radiative forcing by regions, sectors, and climate forcers
Xuanming Su, Kaoru Tachiiri, Katsumasa Tanaka +2
It is important to understand how the emissions of different regions, sectors, or climate forcers play a role on pathways toward the Paris Agreement temperature targets. There are…
Carbon Monitor: a near-real-time daily dataset of global CO2 emission from fossil fuel and cement production
Zhu Liu, Philippe Ciais, Zhu Deng +15
We constructed a near-real-time daily CO2 emission dataset, namely the Carbon Monitor, to monitor the variations of CO2 emissions from fossil fuel combustion and cement production…
Cost-effective implementation of the Paris Agreement using flexible greenhouse gas metrics
Katsumasa Tanaka, Olivier Boucher, Philippe Ciais +2
Greenhouse gas (GHG) metrics, that is, conversion factors to evaluate the emissions of non-CO2 climate forcers on a common scale with CO2, serve crucial functions upon the implemen…
Crystal Structure of Superconducting 1/1 Cubic Au-Ge-Yb Approximant with Tsai-Type Cluster
Kazuhiko Deguchi, Mika Nakayama, Shuya Matsukawa +4
We report the synthesis of a single-phase sample of the superconducting crystalline approximant Au64.0Ge22.0Yb14.0 and present a structure model refined by Rietveld analysis for X-…
Superconductivity of Au-Ge-Yb Approximants with Tsai-Type Clusters
Kazuhiko Deguchi, Mika Nakayama, Shuya Matsukawa +4
We report the emergence of bulk superconductivity in Au64.0Ge22.0Yb14.0 and Au63.5Ge20.5Yb16.0 below 0.68 and 0.36 K, respectively. This is the first observation of superconductivi…
Valence Change Driven by Constituent Element Substitution in the Mixed-Valence Quasicrystal and Approximant Au-Al-Yb
Shuya Matsukawa, Katsumasa Tanaka, Mika Nakayama +6
Quantum criticality has been considered to be specific to crystalline materials such as heavy fermions. Very recently, however, the Tsai-type quasicrystal Au51Al34Yb15 has been rep…
