The ethics of negative emissions

Global Sustainability, 2018
Limiting dangerous climate change is widely believed to require negative emissions. This prospect has sparked concerns about whether negative emissions could be scaled up quickly enough, along with concerns about their likely ethical costs. Building upon

Ionospheric Response to the 8 April 2024 Total Solar Eclipse: Plasma Depletion and Eclipse‐Driven MsTIDs

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

The Real‐Time Advanced Ionospheric Data Assimilation (AIDA) Model

Space Weather, Volume 24, Issue 2, February 2026.
Abstract The Advanced Ionospheric Data Assimilation (AIDA) is a real‐time data assimilation model of global 3D ionosphere and plasmasphere electron density. Changes in the local space environment can occur on very short timescales, particularly during disturbed geomagnetic conditions.

Spatially contextualized analysis of energy use for commuting in India

Environmental Research Letters, 2019
India’s land transport GHG emissions are small in international comparison, but growing exponentially. Understanding of geographically-specific determinants of GHG emissions is crucial to devise low-carbon sustainable development strategies.

Global Ionospheric Slab Thickness Prediction Model Using XGBoost and Ensemble Learning

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The ionospheric equivalent slab thickness is a key parameter for understanding the plasma distribution in the ionosphere, with direct relevance to satellite navigation, communication, and skywave over‐the‐horizon radar. However, traditional prediction methods often suffer from regional biases, limiting their global applicability.

Biodiversity under pressure: In search of sustainable planning strategies

People and Nature, Volume 7, Issue 10, Page 2451-2464, October 2025.
Abstract Land use change in and around urban areas is a major driver of biodiversity loss. Such processes have mostly been studied in large cities, and to a much lesser extent in towns and villages. There is an urgent need for nature positive planning principles that recognize the planetary boundaries and are anchored among decision‐makers.

Attention and positive sentiments towards carbon dioxide removal have grown on social media over the past decade

Communications Earth & Environment
Scaling up CO2 removal is crucial to achieve net-zero targets and limit global warming. To engage with publics and ensure a social licence to deploy large-scale carbon dioxide removal (CDR), better understanding of public perceptions of these ...

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two
