Leading global investment-management firm AllianceBernstein and Columbia University s new Climate School have agreed to bring together investors and scientists to confront the challenges of climate change. As founding member of the school s Corporate Affiliate Program, the firm will facilitate the engagement of commercial enterprise with the university s global climate and sustainability research.
As part of the exclusive three-year agreement, AllianceBernstein and Columbia will embark on research focused on the intersection of climate science with investment decisions. AllianceBernstein s investors and Columbia s experts will interact on climate issues as they arise in the investing process. The project will seek to leverage C

Researchers from Skoltech (Russia) and their colleagues from SINTEF (Norway) have developed a mathematical model of freezing water droplets moving in cold air. This model is a part of a joint RFBR-supported Russian-Norway research project. The project is focused on predicting ice accretion on ships and other offshore structures operated in Arctic climate, which may interfere with their proper functioning and endanger crew members and cargo. The paper was published in the journal
Energies.
Ships travel in cold northern waters under constant bombardment by tiny water droplets populating the chilly air. The droplets are expelled into the air at the impact of sea waves on the ship hull or other surfaces. When they reach the ship s substructure, these semi-frozen droplets can either bounce off or stick. The probability of the droplets sticking to the wall depends on their freezing state, i.e., completely frozen droplets simply bounce off, while others lead to different scena

One of the great mysteries of modern space science is neatly summed up by the view from NASA s Perseverance, which just landed on Mars: Today it s a desert planet, and yet the rover is sitting right next to an ancient river delta.
The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third as much sunshine as we enjoy today on Earth.
But a new study led by University of Chicago planetary scientist Edwin Kite, an assistant professor of geophysical sciences and an expert on climates of other worlds, uses a computer model to put forth a promising explanation: Mars could have had a thin layer of icy, high-altitude clouds that caused a greenhouse effect.

KINGSTON, R.I., April 20, 2021 The Northwest Atlantic Shelf is one of the fastest-changing regions in the global ocean, and is currently experiencing marine heat waves, altered fisheries and a surge in sea level rise along the North American east coast. A new paper, Changes in the Gulf Stream preceded rapid warming of the Northwest Atlantic Shelf, published in
Communications Earth & Environment by recent URI Graduate School of Oceanography graduate Afonso Gonçalves Neto reveals the causes, potential predictability and historical context for these types of rapid changes.

A new paper published in the
Journal of Near Eastern Studies presents the results of and images from the resuming of the archaeological seasons in the Mons Smaragdus region in the Egyptian Eastern Desert. The region is known for Roman-era emerald mines, chronicled by authors like Pliny the Elder and Claudius Ptolemy, were rediscovered in the 19th century by the French mineralogist Fréderic Cailliaud. During the 1990s a team from the Berenike Project started to survey the area and conducted the first excavations, focusing on the main site identified, Sikait, where the archaeological seasons resumed in January of 2018 and January 2020.
