They found that although the slab is sinking
at a rate of less than 1 cm per year, this slow sinking
generates a downward flow in the mantle that is sufficient to pull down the
Earth's
surface and create these huge basins.
Quasars are the discs of hot gas that form around supermassive black holes
at the centre of massive galaxies — they are bigger than
Earth's orbit around the sun and hotter than the
surface of the sun,
generating enough light to be seen across the observable universe.
On the other hand, if the ice shell is sufficiently thick, the less intense interior heat can be transferred to warmer ice
at the bottom of the shell, with additional heat
generated by tidal flexing of the warmer ice which can slowly rise and flow as do glaciers do on
Earth; this slow but steady motion may also disrupt the extremely cold, brittle ice
at the
surface to produce the chaos regions.
Their simulations suggest that
at least one planet in the one to two
Earth - mass range could have formed within orbital distances of 0.5 to 1.5 AUs around both heavy - element - rich stars; of particularly note, the simulations frequently
generated a
Earth - like planet in or near Star B's habitable zone (where liquid water could exist on the planet's
surface).
«We are now finally crossing a threshold where, through very sophisticated modeling of large combined data sets from multiple independent observers, we can disentangle the noise due to stellar
surface activity from the very tiny signals
generated by the gravitational tugs from
Earth - sized orbiting planets,» study coauthor Steven Vogt, professor of astronomy and astrophysics
at UC Santa Cruz, said in a statement.
As others have noted, the IPCC Team has gone absolutely feral about Salby's research and the most recent paper by Dr Roy Spencer,
at the University of Alabama (On the Misdiagnosis of
Surface Temperature Feedbacks from Variations in
Earth's Radiant Energy Balance), for one simple reason: both are based on empirical, undoctored satellite observations, which, depending on the measure required, now extend into the past by up to 32 years, i.e. long enough to begin evaluating real climate trends; whereas much of the Team's science in AR4 (2007) is based on primitive climate models
generated from primitive and potentially unreliable land measurements and proxies, which have been «filtered» to achieve certain artificial realities (There are other more scathing descriptions of this process I won't use).
The jet stream is a fast - moving river of air high in the atmosphere that
generates the weather we experience
at the
Earth's
surface.
The world's climate is way too complex... with way too many significant global and regional variables (e.g., solar, volcanic and geologic activity, variations in the strength and path of the jet stream and major ocean currents, the seasons created by the tilt of the
earth, and the concentration of water vapor in the atmosphere, which by the way is many times more effective
at holding heat near the
surface of the
earth than is carbon dioxide, a non-toxic, trace gas that all plant life must have to survive, and that produce the oxygen that WE need to survive) to consider for any so - called climate model to
generate a reliable and reproducible predictive model.
Here is my opinion: the ocean has two sources of heat,
at surface from solar radiation and
at ocean floor from the heat
generated in the
earth's core.
Just think about the even more simplified model where there is a isotope decay heat source
at the center of the
earth that generates sufficient energy to have a net outward radiative flux of 235 W / m ^ 2 at the Earth's sur
earth that
generates sufficient energy to have a net outward radiative flux of 235 W / m ^ 2
at the
Earth's sur
Earth's
surface.
