URI oceanographers reveal links between migrating Gulf Stream and warming ocean waters
The URI research team noted the importance of finding that the satellite-observed signature of the Gulf Stream’s position relative to the Grand Banks precedes subsurface shelf warming by over a year. “By monitoring satellite observations for changes near the Grand Banks, we can predict changes coming to the Northeast U.S. shelf with potentially enough lead time to inform fishery management decision-making,” said GSO graduate student and co-author Joe Langan.…
Claim: Marine life is fleeing the equator to cooler waters. History tells us this could trigger a mass extinction event
Losing species in tropical ecosystems means ecological resilience to environmental changes is reduced, potentially compromising ecosystem persistence.
In subtropical ecosystems, species richness is increasing. This means there’ll be species invaders, novel predator-prey interactions, and new competitive relationships. For example, tropical fish moving into Sydney Harbour compete with temperate species for food and habitat.…
WMO: “The climate is changing, and the impacts are already too costly for people and the planet”
According to the World Meteorological Organisation, the Climate Crisis is upon us. My question – did anyone notice the crisis?…
Earth Day Connections: NASA Investigates Vegetation
Satellites can detect how “green” an area is – showing the health of plants that are growing in a particular site. While fires, deforestation and drought lead to the tropical Amazon being less green, warming temperatures in the Arctic lead to tundra and boreal regions becoming greener. Using 87,000 Landsat images spanning nearly three decades, scientists found that a third of the land cover of Canada and Alaska looked different in 2012 as compared to 1985. With warmer temperatures, and longer growing seasons, shrubs become denser on grassy tundras, transforming what they looked like from space.…
Northern Red Sea corals live close to the threshold of resistance to cold temperatures
Coral reefs are highly sensitive to temperature change. Therefore, identifying those that respond differently to thermal stress aids in understanding the mechanisms of environmental adaptation in corals. In addition, researchers can focus attention on conserving and studying such unique reefs.…
Listen To Hard Science, Reject Pop Science, To Lessen Global Catastrophe Risk.
“It is likely that we have to capitalize on the insecurity of the educated elite and make them look silly instead of superior and virtuous. We must remember that they are impervious to real science unless it is reduced to their level. When it is reduced to their level, it is imperative that we, at least, retain veracity.”…
