It sounds like you believe CO2 emissions could result in warmer weather that could cause a problem with your hobby.

This year we had record runs of Atlantic salmon returning to our rivers. Even to rivers they haven’t been back to for decades. It would really suck if global warming were to mess it all up.

How many times more would you be willing to pay for gas, electricity and home heat so that this might not happen. Two times the current rates? Three? Four? Five?

Earth is within 1.8 degrees F (1 degree C) of its highest temperature levels in the past million years, Hansen and the others wrote.

But what’s a degree or two?

I don’t know what happened with the data archive, but both your plots are obviously of the Italian data.

Another point which may or may not make a difference to results. It looks to me like the Smith collaiton as archived here http://www1.ncdc.noaa.gov/pub/data/paleo/speleothem/nhtemp-smith2006.txt

has incorrectly collated the Frisia information as archived here – if the archived version hasn’t been changed:
ftp://ftp.ncdc.noaa.gov/pub/data/paleo/speleothem/europe/italy/ernesto2003.txt

The series are the same, but the collated dates are different.

Willis,

It should be noted that Squires Gate and Ringway are airports, so likely have UHL issues, especially Ringway (the old name for Manchester Airport) which has expanded considerably since 1974.

This might answer your question:

or maybe because they were only looking at the past 500 years, plus they say of Mangini – “this result is specifically dependent on the continuity of contribution of the same types of weather systems throughout this record.”

Thanks for your interest. The results are already published on the
internet as a short communication which I’ve attached for your interest.
The actual data are available from the World data center
http://www.ncdc.noaa.gov/paleo/data.html along with many other
previously published well known climate reconstructions.

Unfortunately the length of our reconstruction is limited due to
available data. Yearly growth of stalagmites is very small (~10s of
microns) so actually extracting the annual changes in growth rate is
quite a tedious and time consuming task, hence the lack of datasets and
their short length. One aim of the article is to encourage the
production of more datasets from stalagmites.

One possibility for extending the reconstruction further back in time is
to use isotope or other geochemical information from stalagmites as
well. There a number of recent climate-isotope studies from stalagmites
which do extend much further back in time (glacial-interglacial time
scales) so the potential is there to further develop the work. I am
nearing the end of my PhD so I’m not sure how much I will achieve before
then as this is just one aspect of stalagmite-paleoclimate work I have
been investigating, however my supervisor, Ian Fairchild, has many
collaborators who are doing similar work and I know that they have
recently retrieved some very interesting data from a stalagmite from
Gibraltor which I think covers the Holocene period so would contain the
periods of interest.

I hope that helps to explain a bit of the background to paleoclimatology
from stalagmites. Please let me know if you require any further
information

Thanks

Claire

I also asked Ian Fairchild:

Dear Paul,

Thanks for your message. The work on Gibraltar is being led by my
colleague Dave Mattey from Royal Holloway who has obtained a beautiful
record – but only of the last 50 years! New material has been collected
to try to reach back to the last 1000 years. In this region though,
wetter/drier is more likely to be the key result rather than
warmer/colder. The consensus more generally at the moment is that the
Medieval Warm Period can be distinguished, but was not as warm as the
late 20th century.

Best wishes,
Ian
