What is the term then for science haters?
From Psychology Today (link)
Why all the anger at science?
A legitimate source may be where pseudoscience masquerades as science, either because of capitalist intrigue, or simple credo.
Or, as in the pseudoscience of climate science masquerading as science, perhaps because of communist intrigue in an attempt to redistribute world wealth.
The science haters and nut cases are continually telling us that the arctic will be ice free.

Was it because of global warming that the Skate (see image) was able to surface at the pole in 1958, 1959? (Link)
As Steven Goddard points out (link)
In 2007, our friends went hysterical and told us that the Arctic would be ice free by 2008, 2010, 2012 or 2013. Since then, nothing has changed.

The paper finds a "general buildup of sea ice from ~ 6,000 years before the present" which reached a maximum during the Little Ice Age and "attained its present (year 2000) extent at 4,000 years before the present" |

Thanks for your input john. How about the skate eh.
ReplyDeleteGeoff, your USS Skate photo is Aug 1958

Thanks for pointing out that, as it says in the post above:-
Delete"Was it because of global warming that the Skate (see image) was able to surface at the pole in 1958, 1959?"
(pic retitled)
The aug 1958 photo was not a north pole surfacing geoff, that did not happen until 1958, that 1958 photo does not give location
DeleteNuclear subs can break through up to a few metres of ice. arctic was not ice free at the time of surface as revealed in aug 1959 photo, leave the details just swap photos and you have it
Geoff, the arctic temperature remains at near zero while the ice is melting, the energy taken up by the melting ice. this is not as goddard believes evidence of little melting because temps are low, one cam photo is not the arctic.
Deletethe winter temperatures are getting very high any of the data sets will confirm a massive melt season this year,

Don't forget the ice-age scare of the 1970's. Steven Goddard has had many posts, complements of the IPCC and the Nimbus satellites, which clearly shows Arctic ice "skyrocketing" from the 1974 lows to the 1979 highs. Conveniently lying by omission the warmistas start the conversation with, "Since the start of the climate satellite era in 1979...blah, blah, blah."

7.8.2 Sea-ice Extent and Thickness
.......
Sea-ice conditions are now reported regularly in marine
synoptic observations, as well as by special reconnaissance
flights, and coastal radar. Especially importantly, satellite
observations have been used to map sea-ice extent
routinely since the early 1970s. The American Navy Joint
Ice Center has produced weekly charts which have been
digitised by NOAA. These data are summarized in Figure
7.20 which is based on analyses carried out on a 1° latitude
x 2.5° longitude grid. Sea-ice is defined to be present when
its concentration exceeds 10% (Ropelewski, 1983). Since
about 1976 the areal extent of sea-ice in the Northern
Hemisphere has varied about a constant climatological
level but in 1972-1975 sea-ice extent was significantly less.
In the Southern Hemisphere since about 1981, sea-ice
extent has also varied about a constant level. Between 1973
and 1980 there were periods of several years when
Southern Hemisphere sea-ice extent was either appreciably
more than or less than that typical in the 1980s.

ReplyDelete7. Observed Climate Variation and Change
Pg 225
Gloersen and Campbell (1988) have analysed the
Scanning Multi-channel (dual polarization) Microwave
Radiometer data from the Nimbus 7 satellite from 1978
1987 They find little change in total global ice area but a
significant decrease of open water within the ice Their
time series is short, and it is uncertain whether the decrease
is real
Sea-ice thickness is an important parameter but it is
much more difficult to measure than sea-ice extent The
heat flux from the underlying ocean into the atmosphere
depends on sea-ice thickness Trends in thickness over the
Arctic Ocean as a whole could be a sensitive indicator of
global warming The only practical method of making
extensive measurements is by upward-looking sonar from
submarines Apart from a very recent deployment of
moorings, data gathering has been carried out on voyages
by military submarines In the past repeated tracks carried
out in summer have either found no change in mean
thickness (Wadhams 1989) or variations that can be
ascribed to interannual variability in summer ice limits and
ice concentration (McLaren 1989) Recently however,
Wadhams (1990) found a 15% or larger decrease in mean
sea-ice thickness between October 1976 and May 1987
over a large region north of Greenland. Lack of a
continuous set of observations makes it impossible to
assess whether the change is part of a long term trend. In
the Antarctic no measurements of thickness variability
exist and so far only one geographically extensive set of
sea-ice thickness data is available (Wadhams et al 1987)
Pg 222-223
7.7 Sub-Surface Ocean Temperature and Salinity
Variations
The sub-surface ocean data base is now just becoming
sufficient for climate change studies in the North Atlantic
and North Pacific basins to be carried out. A few, long,
local time series of sub-surface measurements exist,
sufficient to alert the scientific community to emerging
evidence of decadal scale temperature variability in the
Atlantic Ocean. Beginning about 1968, a fresh, cold water
mass with its origins in the Arctic Ocean appears to have
circulated around the sub-Arctic gyre of the North Atlantic
Ocean This event has been described by Dickson et al
(1988) as the Great Salinity Anomaly Some of this cold,
fresh water penetrated to the deep waters of the North
Atlantic (Brewer et al, 1983) The marked cool anomalies
in the North Atlantic SST shown in Figure 7.13 for 1967-
76 partly reflect this event
Recently, Levitus (1989a, b, c d) has carried out a major
study of changes of sub-surface temperature and salinity of
the North Atlantic Ocean between 1955-59 and 1970-74
1955-59 was near the end of a very warm period of North
Atlantic surface waters, but by 1970-74 the subsequent
cool period was well developed (Figure 7.13) Cooler water
extended from near the sea surface to 1400m depth in the
subtropical gyre O0-50°N) Beneath the subtropical gyre, a
warming occurred between the two periods North of this
gyre there was an increase in the temperature and salinity)
of the western sub arctic gyre The density changes
associated with these changes in temperature and salinity
indicate that the transport of the Gulf Stream may have
decreased between the two periods. Temperature difference
fields along 24.5°N and 36.5°N presented by Roemmich
and Wunsch (1984) based on data gathered during 1981
and the late 1950s, are consistent with these ideas

7.8.3 Land Ice (Mountain Glaciers)
Measurements of glacial ice volume and mass balance are
more informative about climatic change than those of the
extent of glacial ice, but they are considerably scarcer. Ice
volume can be determined from transects of bedrock and
ice surface elevation using airborne radio-echo sounding
measurements Mass balance studies performed by
measuring winter accumulation and summer ablation are
slow and approximate, though widely used Section 9
discusses changes in the Greenland and Antarctic ice-caps
so attention is confined here to mountain glaciers
A substantial, but not continuous, recession of mountain
glaciers has taken place almost everywhere since the latter
half of the nineteenth century (Grove, 1988) This
conclusion is based on a combination of mass balance
analyses and changes in glacial terminus positions, mostly
the latter The recession is shown in Figure 7 2, evidence
for glacial retreat is found in the Alps, Scandinavia
Iceland, the Canadian Rockies, Alaska, Central Asia, the
Himalayas, on the Equator, in tropical South America, New
Guinea, New Zealand, Patagonia, the sub Antarctic islands
and the Antarctic Peninsula (Grove 1988) The rate of
recession appears to have been generally largest between
about 1920 and 1960.
Pg 233
Conclusions
.....
Natural climate variations have occurred since the end of
the last glaciation The Little Ice Age in particular
invoked global climate changes of comparable magnitude
to the warming of the last century It is possible that some
of the warming since the nineteenth century may reflect the
cessation of Little Ice Age conditions The rather rapid
changes in global temperature seen around 1920 -1940 are
very likely to have had a mainly natural origin. Thus a
better understanding of past variations is essential if we are
to estimate reliably the extent to which the warming over
the last century, and future warming, is the result of an
increase of greenhouse gases
Sea Level Rise
Pg 263
9.3 Has Sea Level Been Rising Over the Last 100
Years?
It is highly likely that global-mean sea level (MSL) has
been rising This is the general conclusion of no fewer than
13 studies of MSL change over various periods during the
last 100 years (Table 9 1) The estimates range from about
0 5mm/yr to 3 Omm/yr, with most lying in the range 1 0-
2 Omm/yr
John, you're beating it up, the early August Arctic storms as put by Julienne Stroeve of NSIDC:
ReplyDelete-Storm area 1 million square kilometers
-Wave height of 2 to 3 meters broke apart ice into smaller chunks, increasing surface area and thus melting
-Storm mixed fresh water at surface (from melted ice) with deeper warmer saltier water from below increasing melting rate
-Storm agitated water to depths of 500 meters (where water is much warmer) bringing it to surface increasing melt rate
-Low pressure of storm center sucked up water level by 0.3 meters, causing warm water to flow into Arctic Ocean from Pacific Ocean via Bering Strait and from Atlantic Ocean, increasing melting
-Storm rotation (counterclockwise) spread out ice over larger area and pushed ice towards open ocean (on Atlantic Ocean side)
DMI temperature data shows the Arctic summer to be pretty much below average, and if you choose to check, it has been that way since 2001.

Anthony I think you are missing a key point, it doesn’t matter too much what the weather does anymore. Whether you have persistent unusually high pressure over the Beaufort coupled with low pressure over Eurasia such as in 2007, or this summer that didn’t have as favorable weather as in 2007, but had an early August storm, the ice cover continues to be anomalously low in summer. The ice is thinner than it was 20-50 years ago, so that it melts out more easily in summer.
