Data-driven reconstruction reveals large-scale ocean circulation control on coastal sea level

By Sönke Dangendorf et al. Abstract Understanding historical and projected coastal sea-level change is limited because the impact of large-scale ocean dynamics is not well constrained. Here, we use a global set of tide-gauge records over nine regions to analyse the relationship between coastal sea-level variability and open-ocean steric height, related to density fluctuations. Interannual-to-decadal

Climatic and non-climatic vegetation cover changes in the rangelands of Africa

By Francesco D’Adamo et al. Highlights We present a 30+ years continental-scale assessment of African rangeland dynamics. Vegetation was controlled by non-climatic drivers in ca. 26.5% of African rangelands. Most rangelands greened up following a significant increase in woody vegetation. We oppose that greening improves livelihoods as woody plants reduce palatability. Angola and Mozambique showed

UMaine researchers join North Atlantic research voyage studying phytoplankton, ocean carbon

University of Maine researchers are participating in a monthlong research voyage in the North Atlantic Ocean to investigate the degree to which the visual characteristics of the upper ocean captured by satellites reveal information about plankton communities residing there, the amount of carbon dioxide from the atmosphere they fix, and the amount of carbon they

Utilization of CO-rich waste gases from the steel industry for production of renewable liquid fuels

By Tomy Hos and Moti Herskowitz Highlights Production of fuels from CO-rich waste gases is economically viable. “Drop in” renewable fuels can be produced directly by a novel catalytic process. Proposed process improves the energy efficiency and economic value of the gases. CO2 emissions from the steel plant are reduced significantly. Abstract Waste gases generated

North Atlantic Nonsense

by Alan Longhurst “Never before in 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as the Gulf Stream System, has been as weak as in the last decades“.   This announcement from the Potsdam Institute for Climate Impact Research was headlined recently in my morning newspaper in France (and in dozens of others elsewhere) as being

Synthetic Methanol/Fischer–Tropsch Fuel Production Capacity, Cost, and Carbon Intensity Utilizing CO2 from Industrial and Power Plants in the United States

By Guiyan Zang et al. Abstract Captured CO2 is a potential feedstock to produce fuel/chemicals using renewable electricity as the energy source. We explored resource availability and synergies by region in the United States and conducted cost and environmental analysis to identify unique opportunities in each region to inform possible regional and national actions for
