Bad news from East Antarctica. A new paper has been published detailing studies of the Totten Glacier, the largest of its kind in East Anarctica. They find that it is being melted from the underside, not unlike others on the west side of the continent that have been more fully analyzed and are also more advanced. The problem is that once the thinning process has started there is no known way to stop it. In this case the amount of sea level rise that could result is calculated to be about eleven feet over several centuries. This would be added to the ten feet already expected from the destabilized glaciers in West Antarctica.

The role of climate change is certainly a factor, but can be hard to pick out. Parts of the Pacific Ocean have been getting more than their fair share of these storms.

Advances in perovskite solar cell research. This type of solar cell is much cheaper to produce than the commonly used silicon cells, but at this point is not quite as efficient and is still being tested for greater understanding of their unique performance. These cells could eventually have a significantly competitive commercial role, and are thus worth keeping an eye on for new developments that are being reported with much regularity. Today there are two stories that qualify, one of which applies to manufacturing ultra-thin cells for window applications:
The other story relates to findings that help to explain the performance of these cells, which may aid in furthering means of still higher efficiency.
