CO2 levels in atmosphere surpass limit. What now?
2016-06-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: A group of scientists who monitor Earths atmosphere using data from Hawaiis Mauna Loa Observatory announced yesterday that our climate has reached a milestone. The Earth's atmosphere now contains 400 parts per million (ppm) of carbon dioxide, a level of greenhouse gases considered a symbolic limit, the team of researchers wrote in a study published in the journal Nature Climate Change. And that level's not going to change anytime soon, they say. "Our forecast supports the suggestion that...

ScienceDaily: EPFL researchers are pushing the limits of perovskite solar cell performance by exploring the best way to grow these crystals. Michael Graetzel and his team found that, by briefly reducing the pressure while fabricating perovskite crystals, they were able to achieve the highest performance ever measured for larger-size perovskite solar cells, reaching over 20% efficiency and matching the performance of conventional thin-film solar cells of similar sizes. Their results are published in Science. ...
