Two reports have important new information about the history of Greenland’s ice sheet. The information comes from the study of rare isotopes produced in soil by cosmic rays, unless the soil is thickly covered by ice. One of the studies, because of its specific soil location, is more highly provocative than the other.
The better-known pumps sell for prices of around 200 GBP/400 sildenafil without prescription USD (2006).

When these machines sense that you are now adding yet another drug to the mix of things you are already taking, which is never a good idea. tadalafil sales
Here is a more complete report on the highly provocative study. While not totally conclusive it adds a large degree of support to scientists (like James Hansen) who believe Greenland may have nearly melted away during the last interglacial period, 120,000 years ago. We are presently well on our way toward surpassing the peak temperatures reached during that period.

A new study shows huge potential for renewable energy In South America. The continent is blessed with a set of outstanding resources combining wind, solar and hydro. “The study found that these competitive advantages over other parts of the world mean that developing a 100% renewable energy system is not only the cheapest option, but that it is also achievable by 2030.”

The importance of biodiversity and life support systems affecting all of nature. A UN summit meeting devoted to the subject is going on right now, unpublicized. As this story points out, reversing current trends, as spelled out, would greatly help to solve the entire problem of climate change. Not reversing these trends would lead to environmental collapse no matter what else is accomplished.

A new catalyst shows promise toward economically capturing CO2 and converting it to methanol. It could be done in a single process that would dramatically reduce the cost. This work was done at the University of Pittsburgh.

A potentially exciting new idea for creating much more efficient solar cells. The idea was provided by studying the perfectly preserved remains of a 45 million year old fly, which is pictured, followed by experiments indicating an ability of the structure to eliminate any amount of solar reflection. Accordingly, “the fly-eye solution comes “very close to perfection,” and could readily be incorporated into modern solar cells for an impressive boost in energy harvesting.”

A follow-up to my recent story (CL #803) about the possibility that high density supercapacitors may become an alternative to batteries as a standard energy source in transportation and more. I also did a search on David Fermin, the professor at the University of Bristol who did electrochemical testing to validate the work of three PhD researchers at Surrey. The guy is amazing. Credibility should not be an issue here.
