China’s urban EV ultra-fast charging distorts regulated price signals and elevates risk to grid stability

Ultra-fast charging for electric vehicles poses challenges to power grid stability. Here, the authors show that under time-of-use pricing in China, they create sharp demand peaks, and on-site energy storage can worsen the risk.

Arctic Sea Route access reshapes global shipping carbon emissions

Arctic Sea Route access will raise global shipping CO₂ by 8.2% by 2100 and worsen regional inequities. IMO 2023 strategy and Green Corridor plans fall short; only a net-zero pathway with stricter fuels and phased rollout eliminates ASR emissions.

Ships are projected to navigate whole year-round along the North Sea route by 2100

Under low and medium emission scenarios, the Polar Class 7 will be able to sail the Arctic passages with no risk of sea ice motion during the summer and autumn seasons and, from 2065, the whole year-round, according to an analysis that combines climate, sea ice, and navigation data.

Unequal roles of cities in the intercity healthcare system

This study used cell phone data to estimate patient mobility, defined as individuals seeking healthcare in cities other than their city of residence, in China. It found that the three types of patient mobility interweave to form an intercity healthcare system and produce new structural inequalities in local quality healthcare provision among cities.

Unravelling the spatial directionality of urban mobility

Zhao P.J. and his colleagues uncover spatial directionality of urban mobility by using new metrics of anisotropy and centripetality. They find monocentric cities have longer commutes with city expansion, while polycentric cities maintain consistent commuting patterns.

Russia-Ukraine war has altered the pattern of carbon dioxide emissions from shipping in the Black Sea region

Carbon dioxide emissions from shipping in the Black Sea region decreased in Ukraine’s economic zone, and they increased in Romania’s and Turkey’s economic zones, from March 2021 to February 2024, according to an analysis that utilizes a ship emission assessment model.

Extreme rainfall reduces one-twelfth of China’s rice yield over the last two decades

Using data from long-term nationwide observations and multi-level rainfall manipulative experiments, this study reveals that rice yield reductions due to extreme rainfall in China were comparable to those induced by extreme heat over the past two decades. Further projections highlight the increasing risk of rice yield reductions induced by extreme rainfall by the end of this century.
