Parts of New Orleans and its surrounding wetlands are gradually sinking, and while most of the city remains stable, a new study from Tulane University researchers suggests that sections of the region’s $15 billion post-Katrina flood protection system may need regular upgrades to outpace long-term land subsidence.
Public attitudes around solar geoengineering become less politically partisan with more familiarity, suggesting that increasing public awareness of the technology could foster bipartisan engagement.
Extreme droughts in LMICs are associated with increased sexual violence against girls and young women, emphasizing how climate change can indirectly exacerbate social vulnerabilities.
A Dartmouth study uses machine learning to reexamine whether climate change is causing large waves in the polar jet stream that have brought Arctic-like temperatures and storms to temperate regions of the United States in recent years. The researchers constructed a timeline of the jet stream's wintertime variability since 1901 and found it's in the latest of several “wavy” periods from the past 125 years, most of which predate significant effects of climate change. The authors report that climate change is likely not amplifying extreme winter weather by making the jet stream wavier, but through more direct links such as a warmer atmosphere that retains more moisture.
An international collaboration of conservation, environment, and human development experts and practitioners led by the United Nations Development Program’s Human Development Report Office (UNDP-HDRO) proposes a new way for countries to measure and improve their relationships with nature and each other.
How can we accelerate the energy transition in a socially responsible way? Empa researchers propose a publicly funded basic service in solar energy that would increase energy autonomy, create social justice and promote further investment in renewable energies. This requires – among other things – a third of all roofs in Switzerland and a total investment every 30 years that is roughly equivalent to the average gross monthly salary per Swiss citizen.
This special issue on Carbon Capture, Utilization, and Storage (CCUS) addresses the critical role of CCUS in mitigating climate change by bridging energy needs and environmental goals. It explores various aspects of CCUS, including enhanced oil recovery (EOR) technologies, geological storage mechanisms, and CO2 utilization methods. The articles delve into factors influencing CO2-EOR efficiency, innovative materials for profile control in high-temperature applications, and the potential of mineralization-driven storage in sandstones and shales. Additionally, the issue examines safety concerns related to wellbore integrity and proposes solutions for long-term infrastructure durability. Contributions also highlight the development of CO2-mineralized materials from industrial waste, showcasing the integration of decarbonization and waste management. This collection of research aims to foster meaningful discussions and guide future investigations in the field of CCUS.
