Never Say Never
The argument for making synthetic fuel from CO2 using renewable electricity in an increasingly electrified world is by now a familiar one. It hinges on the unlikely scenario that lithium ion batteries will never power the massive fleet of large-volume transportation...
Mitigation and Adaptation in Polycentric Systems
The potential of polycentric governance for promoting both climate mitigation and adaptation is well established. Yet, dominant conceptualizations of polycentric governance pay scant attention to how power dynamics affect the structure and the outcomes of governance.
The Diaper Motor – Producing Energy with Superabsorbers
Osmotic engine: translating osmotic pressure into macroscopic mechanical force
Wastewater Irrigation: Past, Present and Future
With population growth and fast socio-economic development, water shortage is becoming a serious issue worldwide.
Achieving Robust Results on the Causes of Recent Global Warming
A recent review discussed the difficulties of applying, through the use of Global Climate Models, the idea of robustness in climatic attribution studies, i.e., the search for the fundamental causes of recent global warming.
Achieving Gt/y CO2 Utilization with Negative CO2 Emissions
Our global community has been tasked to define and implement a Manhattan style strategy for reducing CO2 emissions at the gigatonne scale. The vision to accomplish this heroic goal is a holistic paradigm, which makes use of all the technologies in the CO2 utilization...
Algae as a Sustainable Raw Material for Biodiesel Production
A recent Review takes an in-depth look at the current status and future prospects of supercritical transesterification.
Amplified Arctic Warming and Mid-Latitude Weather: New Perspectives on Emerging Connections
How the Arctic’s rapid warming may influence weather patterns – and in particular extreme weather events caused by persistent conditions — in heavily populated regions (the mid-latitudes) of the northern hemisphere is discussed in a new article.
Understanding Heat in Australia’s Monsoon Tropics
Australia is well known as a hot country, but how individuals and organizations understand ‘heat’ is surprisingly varied, and is explored in a recent review.
