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 long enough to generate the high temperatures needed for fusion to take place in creating the secondary hydrogen detonation.
«If water temperatures increase as a result of climate change, this could have far - reaching consequences not only for the individual species, but also for the balance of the ecosystem, which has developed 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 temperature tolerance with other important attributes such as nutritional value or rapid growth.
For significant periods of time, the reconstructed large - scale changes in the North Pacific SLP field described here and by construction the long - term decline in Hawaiian winter rainfall are broadly consistent with long - term changes in tropical Pacific sea surface temperature (SST) based on ENSO reconstructions documented in several other studies, particularly over the last two centuries.

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 sensitivOver 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.

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.
