Sentences with phrase «already warmer surface water»

Consider that just moving some of the already warmer surface water to depth (while some upwelling of colder water occurs elsewhere as a compensation) results in an increasing heat content at depths while * simultaneously * producing a decrease in heat content at the surface.

Not exact matches

And around Antarctica, where even the surface ocean water is already quite cold and dense, some of that water in the ocean depths, which is also carbon rich, eventually warmed enough so that it became less dense than the water above it.

Charlie's research told him that during El Niño weather cycles, the surface seawaters in the Great Barrier Reef lagoon, already heated to unusually high levels by greenhouse gas — induced warming, were being pulsed from a mass of ocean water known as the Western Pacific Warm Pool onto the reef's delicate living corals.

Without the periodic upwelling of cold water associated with La Niña, warm water would cover most of the surface of the Pacific, releasing its heat into an atmosphere already warming because of climate change.

Invasive species are entering the region with or without shipping, says Ted Scambos of the National Snow and Ice Data Center in Colorado; warming of the Arctic Ocean's surface temperatures has already increased mixing with foreign waters and all the microbes they contain.

* The Global Coral Reef Alliance says global warming of surface waters is already killing large amounts of coral.

Apologies if this has already been stated, but my view on decreased Arctic ice cover is: - 1, as Judith pointed out, when ice is at a minimum the sun is already so low in the sky that there is no noticeable change to albedo, 2 when there is ice cover warm water is kept at depth by differences in salinity, When there is open water, storms mix the haline layers bringing warm water to the surface where it can more readily radiate it's energy into outer space.

The only way CO2 could absorb any more IR than it is already absorbing is if 1) the surface started re-emitting more IR, which could only happen if more sunlight reached the surface, or 2) atmospheric water vapor levels dropped, freeing up more IR to be absorbed by CO2, in which case, warming would not occur, because that radiation was already being absorbed by the water vapor that disappeared.

The IPCC has already concluded that it is «virtually certain that human influence has warmed the global climate system» and that it is «extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010» is anthropogenic.1 Its new report outlines the future threats of further global warming: increased scarcity of food and fresh water; extreme weather events; rise in sea level; loss of biodiversity; areas becoming uninhabitable; and mass human migration, conflict and violence.
