We don't really
know the magnitude of that lag as well as Barton implies we do, because it is very challenging to put CO2

temperature records from those same ice cores, due to the time delay in trapping the atmosphere as the snow is compressed into ice (the ice at any time will always be younger older than the gas bubbles it encloses, and the age difference is inherently uncertain).

temperature records.
Revkin wrote Hansen: «given that quite a few folks (Gore and some environmentalists particularly) have often used the USA temp trends in arguments for action (string of
record years), its hard for me to ignore the re-analysis of these annual
temperatures...» Its hard to
know exactly what Revkin is aiming to say; there is ambiguity.
Earlier this year, in a mostly interesting lecture about science policy in Australia early this year, Nurse took a cheap shot at Nigel Lawson, accusing him of cherrypicking two points in the
temperature record of the past 20 years to show a standstill, «
knowing» that the other data in the period did not support his point.
High - frequency associations (not shown here) remain strong throughout the whole
record, but average density levels have continuously fallen while
temperatures in recent decades have risen... As yet, the reason is not
known, but analyses of time - dependent regional comparisons suggest that it is associated with a tendency towards loss of «spring» growth response (Briffa et al., 1 999b) and, at least for subarctic Siberia, it may be connected with changes in the timing of spring snowmelt (Vaganov et al., 1999).
In 2005, during the hottest average decade on
record, 8 low - wind conditions
known as «the doldrums» combined with very high ocean
temperatures to cause massive coral bleaching in the Virgin Islands.9 This was followed by a particularly severe outbreak of at least five coral diseases in the Virgin Islands, resulting in a decline in coral cover of about 60 percent.9 There is some indication that higher ocean
temperatures — between 86 and 95 degrees Fahrenheit (30 to 35 degrees Celsius)-- promote optimal growth of several coral pathogens.9 Other research showed that elkhorn coral post-bleaching had larger disease lesions than unbleached specimens, suggesting that bleaching may increase the corals» susceptibility to disease.9, 10
We could lose the entire
temperature record and still
know that C02 causes warming.
We don't even have
records (photographs, descriptions, etc.) of each the
temperature stations themselves, how could we possibly
know if UHI has been correctly accounted for?
If you've ever wondered why you're buried in snow but keep hearing about how we've experienced «officially, the second warmest year on
record» (when we're not being told it could be the warmest year on
record),
know that «officially» relates to the pronouncements of officials, and «official
temperature records» have been «systematically «adjusted» to show the Earth as having warmed much more than the actual data justified.»
And remember, this is not the result of all of the
known problems with the ground based climate
records... these three teams, all comprised of well -
known climate scientists, are using the same
temperature records, and they can't even agree on what the average
temperature of the earth is.
It is interesting how using long national
records that are
known to be reliable - which arent that many - often gives different answers to the global
temperatures dataset which I increasingly think is «manufactured» to suit various purposes.
