Gravest doubts emerged in 2002, when a team led by Oxford's Professor Martin Brasier (co-author of this current study) revealed that the host rock was not part of a simple sedimentary unit but rather came from a complex, high -
temperature hydrothermal vein, with evidence for multiple episodes of subsurface fluid flow
over a
long time.
It could weaken, particularly as its plutonium core bombards it with radiation
over time, subsequently failing to contain the primary fission explosion

over a
long period of
time,» says Luckenbach.
The increased risk of further heat waves (intensive heat
over relatively short
time scales) as well as exposure to warmer
temperatures over the
longer term, suggest that recovery will depend on thermally - resistant individuals that may trade - off high

For significant periods of
time, the reconstructed large - scale changes in the North Pacific SLP field described here and by construction the

time high
temperature records at stations across the United States.
After scientists have done the hard work of working out these relations, it is possible to use one ice - core record to represent broader regions IF you restrict consideration to the parts that are widely coherent, so it is O.K. to plot a smoothed version of an Antarctic
temperature record against CO2
over long times and discuss the relation as if it is global, but a lot of background is required.
Back in 2001, Peter Doran and colleagues wrote a paper about the Dry Valleys
long term ecosystem responses to climate change, in which they had a section discussing
temperature trends
over the previous couple of decades (not the 50 years
time scale being discussed this week).
Heat capacity that is «used»
over a
longer period of
time (penetration of
temperature change through the depths of the ocean and up to regions of upwelling) would leave a more persistent residual imbalance, but the effect would only just stall the full change to equilibrium climate, not change the
long term equilibrium sensitivity.)
Now the slow diffusion processes come into play: heat diffuses from the skin layer downward, and
over a
long period of
time, the entire body of rock becomes the same as the surface
temperature.
Holding concentrations or
temperature (more remotely) to a particular target therefore means limiting cumulative emissions of, say, carbon
over time... a limited amount of
time if we are talking about an iterative approach, and
over a
long period of
time if we are talking about reducing the likelihood of some very nasty consequences well after we (but not our grandchildren — if we are lucky enough to have some) are gone.
Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the sensitivity for CO2 must be less (since there is no time for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even for short term excursions (such as the 8.2 kyr event) has a similar sensitiv

Although the rate of warming of surface air and lower troposphere
temperatures appear to have slowed
over the past few years, the same could be said at any virtually any point in
time by cherrypicking short - term noise and ignoring the
long - term trend (Figure 2).
Over even
longer periods of
time, such as thousand year
time cycles, the effect of CO2 on
temperature is much more noticeable.
Temperatures over that period varied probably by less than 2 deg C, so the climate during which we developed our way of life was very consistent when compared with the
long - term geological
time scale.
My views on the cuttlefish numbers are based on my own observations - as a
long time diver and observer of the cuttlefish I have seen a drastic decline in numbers
over recent years, and I have also noticed a marked increase in seasonal water
temperatures.
3 A) CLIMATE VS. WEATHER Climate is the weather pattern in one place
over a
long period of
time Weather is the current atmospheric conditions, including
temperature, rainfall, wind, and humidity at a given place
Both are at different
time scales, where any (theoretical) influence of CO2 need to change the ocean
temperatures over a sufficient
long period (10 - 30 years), to be visible in the statistics.
It would require a much stronger relationship of
temperature driving CO2 than occurred during the ice age — interglacial oscillations (and it is also important to remember that those changes occurred
over much
longer timescales too... which is the presumed reason why there is a several hundred year lag
time between
temperatures starting to rise or fall and CO2 starting to rise or fall).
You're right that comparing one El Niño to another using a difference from average
temperature would be invalid if the average
temperature «baseline» exhibited a
long - term increasing or decreasing trend
over time.
Meaning, surface
temperatures do not represent total heat of the entire atmosphere well, in this case the heat was really above, this drives surface
temperature sensitivity quite wild
over a
longer time period.
On a
longer time series, going back 140 years to when CO2 first starting increasing,
temperatures are up about 0.6 C to 0.7 C (depending on how much you are smoothing the trends out and ignoring the significant decline
over the past year.)
While we are not suggesting that the current warming trend will necessarily be quickly reversed, this statistical exercise reveals that examining
temperature records
over a
longer time frame may offer a different perspective on global warming than that which is commonly expressed.
Once it ends solar conditions should approach my criteria
over a
long duration of
time which should start global
temperatures on the decline.
Global
Temperature is an example of a bulk property, and it does indeed average out
over sufficient
time scales; hence showing that whatever chaos, spatio - temporal or otherwise, is present in the system on short timescales it does not affect our
longer term predictions.
The
temperature at each land and ocean station is compared daily to what is «normal» for that location and
time, typically the
long - term average
over a 30 - year period.
the MWP is now considered to be an incredibly
long time (
over 500 years) at a higher
temperature than today.
This study showed that in fact many European migratory birds do indeed advance the
timing of their spring migration in response to climate change [so another study in favour of climate (
temperature)
over circadian rhythm for migration
timing] and that it may actually be the
long - distance migratory birds that show better adaption:
(Since
temperature is an intensive property and can not be «averaged» and have any meaning, I'm in the «
long lived stations» camp as they take no averaging... one can just look at min and max trends
over time.
Almost any average
temperature you wish depending on how you slice it and none of it has meaning except in the case that you slice it exactly the same way
over successive measurements
over a
long period of
time might tell you something.
Here's two sentences to get you started: Climate encompasses the statistics of
temperature, humidity, atmospheric pressure, wind, rainfall, atmospheric particle count and numerous other meteorological elements in a given region
over long periods of
time.
Over short periods of
time natural variability such as from ENSO for example, can create short term effects that run contrary to the
longer term trend of increasing ocean heat content and higher tropospheric
temperatures.
When we look
over long enough periods the warming trend is likely to be weaker when the highly volatile
time series are dropped as the most common expectation is that the largest changes in
temperature will ultimately bee seen in the high latitude winter
temperatures.
We're still talking very stable
temperatures over a very
long time, and the variation in the last 130 years is mice nuts.
Consider two emission pathways, both with a cumulative total of 1 TtC, but one with a decaying emissions floor, and one with no emissions floor: the pathway without an emissions floor will cause a
temperature peak earlier than the pathway with the decaying floor, as the emissions floor causes emissions to be emitted
over a
longer time period.
