With Japan’s current plans to reach a fully decarbonized society by 2050 and establish hydrogen society, substantial changes its energy system need be made. Due the limited land availability in Japan, significant amounts of are planned imported both targets. In this paper, novel stochastic version open-source multi-sectoral Global Energy System Model conjunction with power dispatch model is use...

National net zero emission targets could, if fully implemented, reduce best estimates of projected global average temperature increase to 2.0–2.4 °C by 2100, bringing the Paris Agreement goal within reach. A total 131 countries are discussing, have announced or adopted targets, covering 72% emissions. These could substantially lower warming as compared currently implemented policies (2.9–3.2 °C...

We discuss the consequences of the spectral and morphological modification of galaxy cluster radio halos due to the Sunyaev-Zeldovich (SZ) effect for the interpretation of existing and upcoming high frequency radio observations. Likely these modifications have affected the interpretation of the existing Coma cluster radio data. The radio halo emission visible at low ( ∼ < 5 GHz) frequencies is ...
