Another positive feedback of global warming is the albedo effect: less white summer ice means more dark open water, which
absorbs more heat from the sun.
Because ice reflects most light and heat back into space, the exposed water will
absorb more heat as sea ice melts, and further add to the warming.
Because these black
particles absorb more heat than white snow, the study of black carbon concentrations in glaciers is important for predicting future melt rates.
Black
dogs absorb more heat than lighter dogs as they do not reflect the light, but absorb it, so are more prone to heat stress.
The result is more open water in summer, which
then absorbs more heat, warming the ocean and further melting the ice.
The upper layers of the earth's oceans are a lead suspect
for absorbing more heat that otherwise would remain in the atmosphere.
Because dark
things absorb more heat than lighter colored things, causing the dark ice to melt faster than white ice would.
As the two scientists see it, the depths of the North and South Atlantic have
absorbed more heat in the last 14 years than the rest of the global ocean system put together.
(Scientists believe that when trees are cut down, the bare surfaces left
behind absorb more heat than the forest they replaced.
Black asphalt on roads and in parking lots is particularly dangerous because black
objects absorb more heat than lighter ones.
The changes seen in the MSU 4 data (as even Roy Spencer has pointed out), are mainly due to ozone depletion (cooling) and volcanic eruptions (which warm the stratopshere because the extra
aerosols absorb more heat locally).
When ice melts it reveals darker Arctic Ocean water, which in
turn absorbs more heat from the sun, further heating the region.
Darker than the snow and ice, this
debris absorbs more heat from the sun than its surroundings and causes the ice underneath to melt into cylindrical holes up to about a foot deep.
At 0h48 Lindzen says there is no doubt that
CO2 absorbs more heat than O2 Agrees that Human activity has substantially increased CO2 At 0h49 Lindzen, when responding to increasing max high temperature frequency, says that instrumentation changed dramatically during the [instrument record] period.
In a heat - wave, the concrete - and - asphalt fabric of
cities absorbs more heat, and so turns up the dial for its inhabitants; and the high concentrations vehicles and smokestacks can then worsen the trapped air pollution, producing choking smogs.
The darkness of land and water compared with the reflectiveness of snow and ice means that when the latter melt to reveal the former, the area
exposed absorbs more heat from the sun and reflects less of it back into space.
Melting sea ice reduces reflective ice and increases exposure of the sea surface,
which absorbs more heat thus exacerbating the warming affect.
Quantitative analysis has evidenced the acceleration system of melting ice: dark water
surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.
As the Arctic warms, it could alter the jet stream while disappearing sea ice could trigger a positive feedback that drives even more warming around the globe as darker ocean
water absorbs more heat.
Coarser, rockier grains will
absorb more heat from the sun and give it off slowly during the asteroid's night.
For best results use shiny aluminum baking sheets without sides (baked products will brown more quickly on dark coloured baking sheets because
they absorb more heat than the shiny type).
Black color is a bad reflector of sunlight and tends to
absorb more heat.
This was not a one - off event: bright snow is being replaced by dirty ice that
absorbs more heat and melts faster (see Losing its sparkle).
That widespread melting leaves huge swaths of dark ocean water that
absorbs more heat from the sun than the white, reflective sea ice it replaces.
Greenland's snowy surface has been getting darker over the past two decades,
absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows.
Its two faces differ strikingly in color, likely the result of thermal segregation: Over time, darker materials (like carbon) have
absorbed more heat from the sun, warming up and sending lighter, more volatile materials (like ice) to the colder hemisphere.
If the ice melted, it would have reformed only if the temperature grew much colder because water relects less light and
absorbs more heat.
He is experimenting with metal - organic heat carriers, extremely fine particles that can allow fluids to
absorb more heat.
