subject: Information Sheets


I am planning on putting together an Information Sheet for the CRU
web site, titled Sceptical Questions to Climate Change (or something
similar). This Information sheet will of course be vetted by the CRU
board etc.

The answers to the questions would be linked to the other relevant
CRU Information Sheets.

I have a list of questions here, ( I would want no more than ten in
total) that are frequently asked by journos and mentioned by people
of dubious backgrounds. If you could add to these i would be
grateful, provide answers and diagrams even better. I will then
compile them all and send them to CRU Board.

A good question to include would be one that we could emphasise the
whole basis of GHG and radiative forcing, showing that the CO2 vs
Temp relationship is not just an unlinked correlation but based upon
physical relationships and laws.



Q1 - The Earth has been warmer and colder in the past, we have Ice
ages, the Little Ice Age and the Monks were growing grapes for wine
in the 11th Century in York?

Q2. Ice cores show that the Earth's climate fluctuates very rapidly
and quickly in the space of a decade, A fact supported by historical
evidence that shows that the Vikings colonised Greenland.
Note we could also bring in the myth that climate change will cool NW
Europe because of the THC.

Q3 The global temperature record is influenced by urban heat islands
and the individual stations are not reliable?

Q4 Satellite and radiosonde data show that the Atmosphere is cooling,
satellite data are more accurate measurements of the Earth's surface

Q5 Water vapour is the main greenhouse gas and is not included in
climate models and the amount of Greenhouse gases emitted by human
activities is relatively small when compared to the natural emissions?

Q6 Evidence from past records show us that carbon dioxide
concentrations lag behind increases in temperature, therefore the
increases in CO2 concentratiuons that we have seen are because
temperatures are rising because of natural (e.g. Solar) activity?

Q7 The IPCC is not an open process and it is not representative of
the scientific community? For example the Oregon Petition, which
stated "there is no convincing scientific evidence that human release
of carbon dioxide, methane, or other greenhouse gases is causing or
will, in the foreseeable future, cause catastrophic heating of the
Earth's atmosphere and disruption of the Earth's climate. was signed
by 18 000 climate scientists.

Q8 Climate scientists exagerate their findings so that they can get
more research funding?
Note: This is a sensible suggestion, Sonia Bohemia-Christiansen
(formerly of SPRU) used this a s a main argument to discount climate
