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.

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.

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.

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.

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.

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.

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.

It doesn't mean that there can't be any natural variability that appears as wobbles in the temperature record (or in other climate variables), masking the multi-decadal temperature trend over a time scale shorter than 20 years with the effect that the longer term trend is not statistically detectable in the time series, if one chooses the time period only short enough.

However, over long time periods, the variation of the global average temperature with CO2 concentration depends on various factors such as the placement of the continents on Earth, the functionality of ocean currents, the past history of the climate, the orientation of the Earth's orbit relative to the Sun, the luminosity of the Sun, the presence of aerosols in the atmosphere, volcanic action, land clearing, biological evolution, etc..

Jan Perlwitz says:» It doesn't mean that there can't be any natural variability that appears as wobbles in the temperature record (or in other climate variables), masking the multi-decadal temperature trend over a time scale shorter than 20 years with the effect that the longer term trend is not statistically detectable in the time series, if one chooses the time period only short enough.»

As the chart depicts over 12 different time periods (all ending July 2014), reality is that while CO2 levels keep increasing over time, the long - term temperature warming trend (the red curve) is not rapidly accelerating towards a tipping point of climate catastrophe.

Tree rings, coral skeletons, and glacial ice cores (Figure 3) are proxies for annual temperature records, while boreholes (holes drilled deep into Earth's crust) can show temperature shifts over longer periods of time.

This also means, of course, that in a long temperature record, say 100 years, we can * expect * to see a negative trend over a 17 year period five times.

The longer the period over which trends are computed, the more these naturally occurring fluctuations in the temperature time series tend to average out.

Weather is the daily temperature, it can fluctuate to each extreme rapidly whereas climate is an average of temperatures over a long period of time.

This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34

Over longer time periods, however, the differences between different temperature series» settle out, and all show comparable warming temperature trends.

Not because the calculation is complicated — just take how much the global average temperature has changed over some longish time period (a couple of decades or longer) and divide by much energy was used to force that change.

The problem with that argument is that over long periods of time (like the six decades since 1950), positive and negative phases of ocean cycles tend to cancel each other out, and thus internal variability doesn't have a large influence on long - term temperatures.
