Comments Off on Global ocean circulation may be slowing down due to Arctic ice loss

Humanity is entering a phase of grave uncertainty as rising temperatures wreck havoc on our planet. Researchers from Yale University and the University of Southhampton have found evidence that Arctic ice loss may be having a negative impact on the Atlantic Meridional Overturning Circulation (AMOC) , the largest ocean circulation system on the planet. A complex system not easily explained by talking heads scoring political points, AMOC helps regulate ocean and atmospheric temperatures – and its collapse would have repercussions that not even scientists can properly predict. “The ongoing decline of Arctic sea ice exposes the ocean to anomalous surface heat and freshwater fluxes, resulting in positive buoyancy anomalies that can affect ocean circulation,” the researchers wrote in a new study published recently in Nature . “It is found that on decadal timescales, flux anomalies over the subpolar North Atlantic have the largest impact on the AMOC, while on multi-decadal timescales (longer than 20 years), flux anomalies in the Arctic become more important. These positive buoyancy anomalies spread to the North Atlantic, weakening the AMOC and its poleward heat transport. Therefore, the Arctic sea-ice decline may explain the suggested slow-down of the AMOC and the ‘Warming Hole’ persisting in the subpolar North Atlantic.” Related: How climate change could alter the environment in 100 years So what does this mean? Trevor Nace, a geologist, explains for Forbes : “This process whereby water is transported into the Northern Atlantic Ocean acts to distribute ocean water globally. What’s more important, and the basis for concern of many scientists is this mechanism is one of the most efficient ways Earth transports heat from the tropics to the northern latitudes. The warm water transported from the tropics to the North Atlantic releases heat to the atmosphere, playing a key role in warming of western Europe…” Since this is largely unprecedented, it is uncertain exactly what will happen if the AMOC collapses, or how it will affect global weather patterns. But we do know that even small shifts in climate can result in dramatic changes – evidenced by the growing number of droughts, floods and other natural disasters worldwide. In November, temperatures in the Arctic were 20C degrees higher than normal, according to an Arctic Resilience Report . The best way to slow down this trend is to release fewer greenhouse gases into the atmosphere, which requires a shift away from burning fossil fuels and other carbon-producing industries. And that requires leadership. Via Forbes Images via NOAA, NASA

Luxury Tree Villa communes with breathtaking nature in India

Comments Off on Luxury Tree Villa communes with breathtaking nature in India

A picture-perfect getaway roosts in the treetops of west India. Architecture BRIO completed the Tree Villa, a two-story luxury getaway on the cliff of a 160-acre “treesort.” Set within the rich river landscape of Tala near the Kuda caves, the treehouse -like glass dwelling offers an immersive experience within a forested tropical setting. Architecture BRIO built the Tree Villa around existing mature trees, which grow up and through the roof, deck, and fencing, and give the structure its treehouse-like appearance. The dwelling blends into its surroundings with its thatched roof , predominately timber palette, and clean modern design. The architects wrapped the elevated Tree Villa in full-height glazing to optimize views of Tala’s stunning scenery. Tie-dyed bordered sheer curtains filter harsh sunlight during the day. The Tree Villa accommodates four adults and two children. The elevated ground floor is surrounded by an expansive timber deck and comprises a large luxurious bedroom, bathroom with mirrored slats, and a spiral staircase to the upper floor. The larger upper level also features a large timber deck in addition to a second bedroom, loft bed for children, living area, kitchen, dining room, west-facing patio, and a semi-outdoor bathroom that’s dramatically pierced by the enormous brand of an old Garuga fruit tree. The modern and minimalist open-plan interior and lack of walls reinforces the immersive experience in nature. Related: Bamboo-Veiled Dormitory by Architecture BRIO The architects write: “The volumetric compositions of partly white, partly reflective and transparent surfaces within a wooden framework animate and lighten up the space. It questions conventional definitions of exterior and interior and reinterprets notions of privacy and exposure within a hospitality environment. The spatial composition in an otherwise traditional tropical roof structure lends a sense of softness, sensuality, intimacy and complexity, making it a perfect setting for a retreat into the wilderness of Tala.” + Architecture BRIO Via ArchDaily Images © Photographix
