For reptiles and amphibians (herps) we recommend once a year physical exams, weight check, husbandry review (please be ready to provide information
on lights, caging, substrates, calcium and vitamin supplements,
temperatures and what you feed your herp),
yearly parasite exams and further diagnostics if indicated after physical exam.
«The 2 \ sigma uncertainty in the global mean anomaly

on a
yearly basis during high

«Drawdown» refers to the point at which greenhouse gas concentrations in the atmosphere begin to decline
on a
yearly basis, and is the goal for reversing climate change and reducing global average
temperatures.
Incidentally, If we take the average of UAH and RSS
on a monthly basis, then calculate the average
yearly temperature,...
As the real science dictates, by the end of the next 20 years the
yearly CO2 reduction of 76 million plus tonnes will have zero impact
on global
temperatures.
Figure 5.3 shows the linear trends (1955 to 2003) of zonally averaged
temperature anomalies (0 to 1,500 m) for the World Ocean and individual basins based
on yearly anomaly fields (Levitus et al., 2005a).
I know that the data that is presented
on global
temperatures daily, monthly and
yearly, is not raw data; it has had a considerable amount of processing before it is presented as an average global
temperature.
It fails to show the type of variation in
temperature that happens
on a
yearly basis, much less the variation that takes place over time.
In other words,
temperature controls CO2 levels
on a
yearly time - scale, and according to Salby, man - made emissions have little effect.
However, CO2 does not rise and fall with the
temperature on an hourly, daily or even
yearly basis.
It is instructive to compare these numbers with those characteristic of a set of the years during 1979 — 2012 with no or only one major regional extreme event (in terms of land surface
temperature and land precipitation anomalies) in the NH midlatitudes, from late April / early May to late September / early October, as reported
yearly since 1993 in the World Meteorological Organization statements
on the status of the global climate (see also ref.
Moreover the recent decline of the
yearly increments d (CO2) / dt acknowledged by Francey et al (2013)(figure 17 - F) and even by James Hansen who say that the Chinese coal emissions have been immensely beneficial to the plants that are now bigger grow faster and eat more CO2 due to the fertilisation of the air (references in note 19) cast some doubts
on those compartment models with many adjustable parameters, models proved to be blatantly wrong by observations as said very politely by Wang et al.: (Xuhui Wang et al: A two-fold increase of carbon cycle sensitivity to tropical
temperature variations, Nature, 2014) «Thus, the problems present models have in reproducing the observed response of the carbon cycle to climate variability
on interannual timescales may call into question their ability to predict the future evolution of the carbon cycle and its feedbacks to climate»
His point seemed to be, in part anyway, that after 30 years the difference in
temperature is no more than a fairly ordinary
yearly transition one sees every 8 years,
on average.
Likewise, a statistician will not automatically be aware of the difference between proxies of low resolution (which may be good at estimating average
temperature on a decadal or even centennial scale) and proxies of high resolution that are good at estimating
temperature at a
yearly level.
Presenting the magnitude of the
temperature change over the past century relative to how much the
temperature changes
on a daily or
yearly basis can be quite an eye opener to many people who seem to believe this warming is «dramatic».
It is also worth noting that tropical tropospheric amplification is well - verified by the satellite and balloon data for the
temperature fluctuations that occur
on monthly to
yearly timescales, e.g., due to ENSO.
I don't think these new results will in any case affect the
yearly mean
temperature grid calculations, as they depend
on actual surface station
temperature records — which both we and Steig et al. used — and not
on reconstructed gridded data.
The TAR discussed various attempts to use proxy data to reconstruct changes in the average
temperature of the NH for the period after AD 1000, but focused
on three reconstructions (included in Figure 6.10), all with
