Norsk Geologisk Forening - Vintermøte 2015
« on: 08.01.2015, 14:27:46 »
Den 12. til 14 Januar avholder Norsk Geologi Forening sitt årlige vintermøte i Stavanger.
Tema nummer ett med påfølgende paneldebatt dreier seg om klima og geologi.

Er det noen av dere som skal dit?  Er det noen dere kjenner man kan henvende seg til for Ã¥ fÃ¥ noe referert fra dette arrangementet?

T1 â?? Klima og geologi / Climate and Geology

Klima og effektene av klimaendringer er i følge FNs klimapanel (IPCC) en av de største utfordringene vi står ovenfor i vår tid. Det har derfor vokst fram et omfattende forskningsområde som går på tvers av de tradisjonelle geofaglige disipliner. I denne sesjonen ønsker vi å belyse sammenhengene mellom geologi/geologiske prosesser og klima, det være seg paleoklima generelt, inkludert raske klimaendringer og masseutryddelser eller istider. Sesjonen vil også dekke geohazards som et resultat av klimavariasjoner, for eksempel ulike typer skred.

Finnes det geologiske årsaker/forklaringer til klimaendringer? Er det sammenheng mellom klimaendringer og platetektonikk? Hvor mye av temperaturstigningen på Jorda siden 1850 mener en er menneskeskapt? I denne sesjonen oppfordrer vi geologene til å delta i klimadebatten, derfor inviterer vi også til paneldebatt under konferansen.

En rapport fra Geologiforeningens Vintermøte #31 I Stavanger finnes her  : http://www.geologi.no/konferanser/vinterkonferansen-2015

Her var ikke så mye hot stuff som jeg ønsket meg men mer generelle betraktninger. Det kan vel tyde på at dette som her presenters er det generelle synet blandt Norske geologer hva gjelder den IPCChypede forklaringen om androgen årsak til klimaendringer.

Her fra Humlum:
Climate change since 1850: What
may be learned from observations?

Humlum, O.
Department of Geosciences, University of Oslo,
Ole.Humlum@geo.uio.no

Since 1850 AD the global temperature has increased as
the Little Ice Age came to an end, and planet Earth
entered the modern warm period. There is today little
doubt that man can affect climate, and there is no doubt
that any modern climatic change plays out on a
background of natural climate changes.
The current debate on climate change and its main
causes revolve around determining the relative
magnitude of natural and anthropogenic contributions to
modern climate change, especially since year 1975. At
the moment there are at least two main conception
schools involved in this scientific debate: A) Modern
climate change is mainly caused by natural variations,
and B) modern climate change is mainly the result of
anthropogenic activities. The Intergovernmental Panel
on Climate Change (IPCC) bases its advice to
governments on the assumed truth of school B, and
points out that in particular after 1975 the global
temperature increase is unique, and can only be
explained by assuming a dominant role of the
anthropogenic component of climate change, driven by
the release of CO2 from fossil fuels.
This lecture uses different measured data series to
document aspects of global climate change since 1850,
and examines to which degree the most recent
development since 1975 stands out as being unique in
the 1850-2014 time perspective. In addition, a number
of important natural climate variations documented by
such observed data are highlighted. Few, if any, of these
natural variations are today incorporated in or
represented by modern climate models. They are,
however, important to understand the dynamics of
global climate change since 1850, including the most
recent period after 1975, and to evaluate the relative
importance of natural versus anthropogenic
contributions to modern global climate change.

..og fra Siggerud
Climate and geology - worlds apart?
Siggerud, E.I.H.
NTNU

Over the last two decades a strange word has entered
into the world of natural science - the word â??believeâ?? in
â??climate changeâ?? due to increasing omissions of CO2.
The later projected as a man-made version of the 13th
century Black Plague whereby the alleged current rise in
temperature, if we are to believe the Intergovernmental
Panel of Climate Change (IPCC), will be the end of
civilisation as we know it.
As natural scientist we should be dismayed, at the very
non-scientific â??belief in climate changeâ??, and more so by
the notion that climate somehow is detached from
geology. As geologist we deal with the result of
changes in climate every day and our scientific research
teaches us that climate have always changed, the proof
is documented in the geological record. This record tell
of a continuous changes between green-house and icehouse
periods throughout the Earth history while also
show an overall decreased temperature since the Early
Cambrian. The geological record also show prolonged
periods of much higher concentrations of CO2 in the
atmosphere e.g. during the Cretaceous enabling microorganisms
to extract calcite from the sea-water to
produce the famous chalk deposits in Western Europe.
This of-cause begs the question, why has it been warmer
and colder in previous geological time periods on a
scale much larger than the alleged changes in
temperature reported during the last century.
One interesting data point is the Vostok ice-core from
Antarctica that record a variation in temperature over a
period of the last 450,000 years, which clearly show
variations in temperature on a much larger scale than
alleged changes to day. Similarly, even documented in
the human history, is the cooling that led to the little ice
age from1300 until 1850. However, the temperature
variation recorded during the little ice-age fall well
within the smaller scale changes observable in the data
from the Vostok ice-core. Ironically 1850 coincides
with when first scientific monitoring of temperature
began erroneously contributed to human interaction. It
becomes even more ironic when the temperature rise
levelled of around 1900 and has remained the same
throughout most of the 20 century. Interesting too
because todays temperature is several degrees colder
than during the time period prior to the little ice age
from 800 late 1200. This also raises the question, when
stated that we need to keep a minimum raise in
temperature of less than 2 degrees Celsius, when we
know that even in historic times the temperature have
been higher without the world going asunder.
The double irony is that todays debate is free of
geology, the only science with a long enough timerecord
to put the current lack of temperature variation
into a more coherent scientific picture. More so natural
â??disastersâ?? experienced around the world today are being
referred back to todays alleged â??human caused climate
changeâ?? while they are in fact normal geological
happenings of which we find evidence in the rockrecord
going back into the Precambrian.
Subsequently, this is not a time for believing in or fear
of climate change, but a time when we geologists as
natural scientist needs to get involved to bring the
debate into a scientific path focusing on where our
human activity does make an impact rather than wasting
enormous sums of money on trying to alter the intensity
of the sun and the rotation pattern of the earth around
the sun that causes the real

Androgen årsak til at klimaet forandres? Høres ut som real kjønnsdiskriminering.

Stusser litt på ordbruken her jeg også. Men det er vel ikke lenge før mannfolka får skylda. "Maskulin menneskeskapt oppvarming".

 ;D Godt jeg ufrivillig kan bidra med litt humor her :D

Det skal selvsagt stå "antropogen" ;D

De hevder at geologi er en disiplin som er stilt utenfor i IPCC sine rekker. Selv mener de at de tydligste svarene om hva som skjer i klima finnes i geologiske sedimenter og at svarene er tydelige.
Kanskje det er en bevisst startegi fra IPCC og ikke befatte seg særlig med geologi:-)
