Miniaturization is the key: Experiments that once required a room full of lasers, optical elements, and vacuum systems can
now fit in a device the size of an
ice chest, with the atoms trapped
on the
surface of a microchip.
In that case, the
ice seen
on the
surface now would once have been buried beneath dust and rock that insulated it from the sun's heat and prevented it from escaping into space.
For
now, the second - highest priority mission
on NASA's wish list is the Jupiter Europa Orbiter, which would survey the
ice - covered moon Europa and the global ocean that seems to lie beneath its frozen
surface.
After comparing it with domes
on Earth, scientists
now believe Ahuna Mons formed when a slushy mix of internal
ice and natural antifreeze reached the
surface along a duct — just as magma builds volcanoes
on our planet.
Scambos's group predicted the final Larsen B collapse using a model that looks at how much meltwater has pooled
on the
surface of the
ice, and he
now hopes to apply the model to bigger Antarctic
ice shelves.
Now a team of astronomers, led by Tobias Owen of the University of Hawaii, has discovered nitrogen
ice on Pluto's
surface (International Astronomical Union Circular, No 5532).
Now a weather station, installed
on the Larsen C
ice shelf in 2015, has revealed that a quarter of
surface melting occurs in the winter because of föhn winds, Peter Kuipers Munneke of Utrecht University in the Netherlands told a meeting of the European Geosciences Union in Vienna last week.
Even deeper oceans of 60 to 125 miles (100 to 200 km) are
now believed to lie below
surface ice on Callisto and Ganymede, which orbit further out from Jupiter.
Now, a new study led by Brown University researchers suggests that there could be much more
ice on Mercury's
surface than previously thought.
«Dawn scientists can
now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material
on the
surface, possibly
ice,» Christopher Russell of the University of California, Los Angeles, and principal investigator for the Dawn mission, said in a statement.
Now it appears an
ice analog of these plates exists
on the
surface of Jupiter's moon Europa.
The water
ice counteracts the traditional danger of living above ground by serving as a radiation barrier, offsetting fears of solar exposure that have, until
now, projected Martian architecture into a dark underworld — buried beneath a regolithic
surface that is believed to contain perchlorates, gypsum and other substances hazardous to human life.Water as a Radiation Shield By taking advantage of water -
ice's ability to filter the sun's rays and protect against radiation,
ICE HOUSE prioritizes a life above ground and celebrates the human presence
on the planetary
surface.
Richard B. Alley, an expert
on Greenland's
ice sheet at Penn State, told me it's still possible that flows of meltwater from
surface lakes could start large areas of
ice moving seaward, particularly if the melt zones continue to expand inland as they have been doing for years
now.
However, there is both theoretical and observational evidence that melting
now occurs
on the horizontal
surfaces of the Kilimanjaro Northern
Ice Field, and contributes to ablation [Moelg and Hardy 2004; Thompson et al 2002].
This result would be strongly dependent
on the exact dynamic response of the Greenland
ice sheet to
surface meltwater, which is modeled poorly in todays global models.Yes human influence
on the climate is real and we might even
now be able to document changes in the behavior of weather phenomena related to disasters (e.g., Emanuel 2005), but we certainly haven't yet seen it in the impact record (i.e., economic losses) of extreme events.
What scientists once thought was a fairly simple linear process — that is, a certain amount at the
surface of an
ice sheet melts each year, depending
on the temperature — is
now seen to be much more complicated.
Indeed, as I mentioned back in Germany, the earth is
now thought to have become completely covered with
ice and snow
on some occasions, all of the land and sea
surfaces white except for a few hot springs areas such as Iceland.
The High Latitude L2 Sea and Sea
Ice Surface Temperature product is
now operationally available
on EUMETCast and FTP.
Up until
now, this kind of
surface dynamic has not been documented
on the gigantic, and not - so - long - ago - thought - invulnerable East Antarctic
ice sheet.
We can make good estimates of global temperature so can estimate planck radiation (
on global level), good estimates of albedo from
ice extent, reasonable estimates of evaporation and convection from temperature contraints,
now try closing that
surface budget with GHG.
