When I was an early stage doctoral student, our professor asked each of us to turn to someone in the room and explain our upcoming dissertation idea. Whoa! That was tough, as our colleagues didn’t necessarily share our disciplinary background knowledge nor the jargon that we took for granted in … [continued]

Right: Estimates of the Earth energy imbalance for successive overlapping 20-year periods and the most recent decade (right). Shaded regions indicate the very likely range (90–100 % probability), while the stars show the CERES (NASA Clouds and the Earth’s Radiant Energy System) estimates for comparison.

The planet is heating up more quickly than ever before. For decades, greenhouse gas emissions caused by human activity have been building up in the atmosphere and trapping ever-higher levels of heat. The resulting asymmetry between incoming solar energy and energy radiated back out into space — known as “Earth’s … [continued]
Each time we see a photograph of bleached coral reefs, we feel saddened — there is no greater iconography of the climate crisis that surrounds us. The United Nations warned this month of a “deepening crisis” for oceans, outlining a trajectory of intensifying heat absorption, pollution, and overfishing. Then again, … [continued]
Four leading climate scientists are warning that geoengineering is a fool’s game with potentially catastrophic consequences.
The National Science Foundation has reversed its idiotic order in May to dismantle the Ocean Observatories Initiative.

It’s time for another rundown of the most popular stories of the past week here on CleanTechnica. Take a look below at what grabbed people’s interest, and then also see the various CleanTechnica originals we published in the past week. Most Efficient Solar Module in the World — New Record … [continued]
We’ve written for years about how much solar power potential countries have, how much onshore and offshore wind power potential countries have, and how much solar power growth is occurring in countries around the world — but what about offshore solar power potential? That was never really part of the … [continued]
Floating solar PV power has been one of the most interesting and fun segments of the global solar power industry in the past decade. When it started popping onto the scene, it was catchy, but one wondered, was it really practical and cost effective? As it turns out, the benefits … [continued]

The Fraunhofer Institute for Solar Energy Systems (ISE) is no stranger to solar power records, and it’s just set another one. Via its own III-V germanium solar PV module, the institute reached 34.4 percent solar module efficiency. The solar record march goes on. “The solar cells were developed by AZUR … [continued]
The energy-efficient desalination system produces fresh water without chemical additives and transforms leftover salts into useful materials. Big takeaways A new desalination method produces drinking water from seawater without chemical additives. The solar-powered system uses specially engineered black metal to absorb sunlight. Its self-cleaning surface separates and collects salts, instead of dumping them as harmful … [continued]
