E-Mail Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a University of Maine-led study. Overall, sea ice has been on the rise for about 10,000 years, but with some exceptions to this trend. Dominic Winski, a research assistant professor at the UMaine Climate Change Institute, spearheaded a project that uncovered new information about millennia of sea ice variability, particularly across seasons, in the Southern Hemisphere by examining the chemistry of a 54,000-year-old South Pole ice core. The Southern Ocean experiences the largest seasonal difference in sea ice cover in the world, with Antarctica surrounded by 18.5 million-square-kilometers of sea ice in the winter and only 3.1 million-square-kilometers of it in the summer. According to researchers, this seasonal disparity in sea ice has a significant influence on regional and global climate, yet scientists for years knew relative ....

‘Canal War’ Breaking Out in Greater Caspian Region Publication: Eurasia Daily Monitor Volume: 18 Issue: 69 The Volga-Don canal in Russia (Source: Wikimedia Commons) Turkey’s plan to build a canal bypassing the Bosporus Strait and potentially upsetting the Montreux Convention (see EDM, February 9) along with Russia’s movement of warships from the Caspian to the Sea of Azov via the Volga–Don Canal in order to threaten Ukraine (see EDM, April 13) highlight the ways in which artificial waterways can play a significant geopolitical role possibly as dramatically as the late-19 th century “Railway Wars” did in the Middle East. Those two developments have attracted widespread international attention in and of themselves. But a broader trend, likely to play an increasing role in the geopolitics of the greater Caspian region, has yet to garner notice. That is the emergence of competition among existing and planned canal systems from the Caspian to the Black Sea ....
E-Mail IMAGE: A lightning mapper at the High Altitude Water Cherenkov (HAWC) Cosmic Ray Observatory in Mexico unexpectedly observed that gamma rays produce more neutrons than previously known. view more Credit: Jordan Goodman, HAWC Collaboration (NSF.gov) LOS ALAMOS, N.M., April 28, 2021 Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like - by observing neutrons generated from soil by very large cosmic-ray showers. The work took place at the High Altitude Water Cherenkov (HAWC) Cosmic Ray Observatory in Mexico. This was an accidental discovery, said Greg Bowers, a scientist at Los Alamos National Laboratory and lead author of the study published in ....
