Better detection, not global warming, behind increase in large
Antarctic icebergs "Dr. Long's analysis shows that the increase is only an 'apparent
increase,' and that it is premature to think of any connection between
this kind of iceberg (growth) and global warming," said Douglas MacAyeal,
a University of Chicago glaciologist who tracks icebergs. "His research,
particularly that with his amazing ability to detect and track icebergs,
is really the best method" for determining the actual rate of the
creation of icebergs. Long and his student assistants have pioneered the use of images generated
from the SeaWinds-on-QuikSCAT satellite for tracking icebergs. The NASA
satellite carries a device called a scatterometer, which measures the
wind speed and direction by recording the reflection of radar beams as
they bounce off ocean waves. Until recently, the resolution of the images
generated by the scatterometer was too low to distinguish icebergs. Long's
team developed a computer processing technique that produces images sharp
enough to reliably track icebergs. Ref: D.G. Long et al, Is the number of icebergs really increasing?
Eos 83, No 42, Oct 24, 2002 2B. Antarctic sea ice season lengthens overall Ref: Parkinson, C.L. Trends in the length of the southern Ocean sea-ice season, 1979-99. Annals of Glaciology 34: 435-440, 2002. What was done? Satellite passive-microwave data were used to calculate and map the length of the sea-ice season throughout the Southern Ocean for each year of the period 1979-99. What was learned? Over the 21 years of the study, most of the Ross Sea has, in the words of the author, "undergone a lengthening of the sea-ice season, whereas most of the Amundsen Sea ice cover and almost the entire Bellingshausen Sea ice cover have undergone a shortening of the sea-ice season," while "results for the Weddell Sea are mixed." Overall, Parkinson reports that "the area of the Southern Ocean experiencing a lengthening of the sea-ice season by at least 1 day per year over the period 1979-99 is 5.6 x 106 km2, whereas the area experiencing a shortening of the sea-ice season by at least 1 day per year is 46% less than that, at 3.0 x 106 km2." What it means? Although different sea-ice trends are clearly occurring in different
sectors of the Southern Ocean, there is no question that "a much
larger area of the Southern Ocean experienced an overall lengthening of
the sea-ice season over the 21 years 1979-99 than experienced a shortening,"
according to the author, which, according to simple logic, is absolutely
contrary to what would be expected in a world that climate alarmists claim
was concurrently experiencing a warming they describe as unprecedented
over the past thousand years. **************************************************************** 3. The IPCC Hockey Stick is contradicted by other paleo-data and by solar observations In 1999, a paper Dr. Michael Mann (Department of Geosciences, University of Massachusetts) et al., published in `Geophysical Research Letters' altered the whole landscape of how climate history of the past 1000 years was to be interpreted. It also stood in stark contrast to other analyses of proxy data and to the challenge posed by the solar scientists. The infamous `Hockey Stick' was adopted by the IPCC to claim that the 20th century was the warmest in 1000 years. Using tree rings as a basis for assessing past temperature changes back to the year 1,000 AD, supplemented by other proxies from more recent centuries, Mann completely redrew the history, turning the Medieval Warm Period and Little Ice Age into non-events . From his diagram, the Medieval Warm Period and Little Ice Age have disappeared, to be replaced by a largely benign and slightly cooling linear trend in climate - until 1850 AD. . His climate record shows no evidence of solar influences but matches more or less the concentration of atmospheric CO2. In every other science when such a drastic revision of previously accepted knowledge is promulgated, there is considerable debate and initial skepticism, the new theory facing a gauntlet of criticism and intense review. Only if a new idea survives that process does it become broadly accepted by the scientific peer group and the public at large. This never happened with Mann's `Hockey Stick'. The coup was total, bloodless, and swift as Mann's paper was greeted with a chorus of uncritical approval from the greenhouse industry. Within the space of only 12 months, the theory had become entrenched as a new orthodoxy. The ultimate consummation of the new theory came with the release of the draft of the Third Assessment Report (TAR-2000) of the IPCC. Overturning its own previous view in the 1995 report, the IPCC presented the `Hockey Stick' as the new orthodoxy with hardly an apology or explanation for the abrupt U-turn since its 1995 report. They could not even offer any scientific justification for their new line. Before and since the Mann, Bradley, Hughes paper, other analyses showed large climate variability in the past 1000 years, with a medieval warm period (MWP) temperature maximum around 1100AD, followed by the Little Ice Age (LIA) from about 1270 to 1850AD. The final blow to the Hockey stick has come from Lonnie Thompson et al (Science 298, 589-593, 2002) who report a LIA in the tropics. Their finding contradicts the IPCC claim that the LIA was a local event confined to NH high latitudes and Europe. ********************************************************************* 4. From Jim Hansen's E-mail to Climate Skeptics (10/27/02) "I would not be surprised at all if, when an unusual injection of
CO2 is put into the air, as it has been, that there are some pathways
for some of it to get out of the air, into the ocean, land, biosphere.
The question is how large those pathways are -- minor or substantial The
growth of CO2 in the air has been smaller, given the magnitude of the
fossil fuel injection, than most carbon cycle people would have predicted,
so maybe some path(s) are significant. As years go by we will get more
empirical data on this, so it is interesting. That is why I like to make
graphs of the data, e.g., the ratio of "air borne" CO2 to fossil
fuel emissions. I have no expertise on this at all, but my gut feeling
is that the experts have understated somewhat the ability of the ocean
and biosphere to take up excess CO2, but the jury is still out." 5. Length of growing season and CO2 From CO2 Science Magazine, 23 October 2002 http://www.co2science.org/subject/g/summaries/growingseason.htm References: ***************************************************************** 6. Fixing global warming costs 'next to nothing' say "experts" [SEPP comment: This is not our story. We put the quotes around "experts"] A Swedish economist says fixing global warming now will have next to no impact on the long-term global economy. He uses the same economic data as those who tell President George Bush that industry will suffer if he stops them polluting. People are expected to be five times richer in 100 years time but the new study says that will be delayed by just two years if politicians act now. Christian Azar, a Swedish energy economist, teamed up with US climate scientist Stephen Schneider to carry out the study. They believe their work will persuade the public that acting now will bring few hardships. Azar says he has based his work on the same figures used by Bush's advisors but claims his report just puts the cost in context. Those advisors predict stabilizing carbon dioxide at twice their pre-industrial levels would cost between $1 trillion and $8 trillion. Although that sounds like a lot, Schneider says the same economists predict a 2% annual economic growth rate, which would almost mask the long-term cost. Schneider claims http://www.newscientist.com "To be 10 times richer in 2100 versus 2102 would hardly be noticed." He adds: "The wild rhetoric about enslaving the poor and bankrupting
the economy to do climate policy is fallacious, even if one accepts the
conventional economic models." SEPP Comments: Stabilizing CO2 levels require more severe emission restrictions than called for by Kyoto and must involve the developing nations as well. Of course, Azar/Schneider never consider the benefits that could be derived from alternative uses of $1 to 8 trillion. Both authors serve on the Editorial Board of the journal; we wonder who peer-reviewed their study. ************************************************************************ 7. News from COP-8 NEW DELHI: Prime Minister Atal Bihari Vajpayee on Wednesday hit out at the industrial nations for demanding greater commitments from developing countries for preventing climate change. Vajpayee said developing countries should not be set the same targets as rich countries when it comes to emission reduction. Developing countries, however, have to make inventories of their emission levels and develop national action plans for cutting them back -- with financial and technical help from developed nations. "Per capita greenhouse gas emissions (of developing countries) are only a fraction of the world average and in order of magnitude below that of many developed countries This situation will not change for several decades to come. We do not believe that the ethos of democracy can support any norm other than equal per-capita rights to global environment resources," Vajpayee said The UN conference [COP-8] in New Delhi, in which 169 countries are participating, is focusing on future action needed to tackle global warming and preparatory work to be done ahead of the Kyoto Protocol coming into force early next year. ********************************************************************* 8.
