By your calculation, if we are able to reduce today's emission rate of by 50 % in the next 40 years (by 2050) to result in 450 ppm, then maintain that emission rate for the next 50 years (by 2100) to 500 ppm,
the resulting difference in temperature would potentially be 2.2 deg C?

differences in temperature.
These divergences suggest that there is still a lot of uncertainty surrounding satellite
temperature records that needs to be resolved, as the range of reasonable assumptions for corrections can lead to large
differences in results.
This decrease
results because plant respiration also increases with
temperature, and some of the photosynthetic gains (that lead to increased productivity) are lost through a) growth and maintenance respiration (Ryan et al. 1995), or b) seasonal
differences between photosynthetic gains
in the spring and increased respiration
in the fall.

I would expect greater resolution
in the adjustments than that, and I can imagine different outcomes based on different textures and patterns
in ship - buoy
differences — if conditions,
temperature, season, humidity, etc. have a systematic influence on the S - B
difference, and this skews the mean
difference in a way that affects our
results.

If a doubling of CO2
resulted in a
temperature increase of approximately 1 K before any non-Planck feedbacks (before water vapor, etc.), then assuming the same climate sensitivity to the total GHE, removing the whole GHE would
result in about a (setting the TOA / tropopause distinction aside, as it is relatively small relative to the 155 W / m2 value) 155/3.7 * 1 K ~ = 42 K. Which is a bit more than 32 or 33 K, though I'm not surprised by the
difference.
IMHO, the increase
in speed of the Hadley / Walker cells may be the
result of higher ocean
temperatures (or
temperature differences over long distances), not the origin (or to a lesser extent, as less clouds lead to some extra insolation, thus warming).

difference of about a factor of two between the most - and least - severe projections.
Weather often occurs as a
result of
differences in temperature and pressure from one place to another.
A prominent (
in the media, anyway) research study last year by Rutgers's Jennifer Francis and University of Wisconsin's Stephen Vavrus suggests that the declining
temperature difference between the Arctic and the lower latitudes (adding greenhouse gases into the atmosphere warms colder, drier regions more so than warmer, wetter ones — with the notable exception of Antarctica) has led to changes
in the jet stream which
result in slower moving, and potentially stronger East Coast winter storm systems.
Reporting problems include
differences due to the net
result of conversions off low data metered at varying
temperature and pressure bases and converted to a standard

resulting from the merger of data reporting systems that vary
in scope, format, definitions, and type of respondents.

The overall level of consistency between attribution
results derived from different models (as shown
in Figure 9.9), and the ability of climate models to simulate large - scale
temperature changes during the 20th century (Figures 9.5 and 9.6), indicate that such model
differences are likely to have a relatively small impact on attribution
results of large - scale
temperature change at the surface.
On a seasonal basis the ranges between the daily maximum, minimum and average are all listed and the lowest ratio is that the daily minimum

Pat, the lag to which you allude,
in fact, makes a minor but significant
difference to «the
result» (meaning the correlation between CO2 and
temperature in the record), but whether or not it does is really very much beside the point.

temperature and their
results agree with our finding; the small
differences in values and ranking are expected because of the small uncertainty
in each group's
results.»
Instead of this evidence showing that there is no UHI increase
in the main
temperature indices, an alternative explanation for the empirical evidence is that, for whatever reason, actual urban changes do not
result in a material
difference in trend for calm Tmin than for windy Tmin.
That is, you have to interpret Jelbring as using «
temperature» not as we all learned it
in connection with the Ideal Gas Law but rather as the quantity whose

The net
result is that
in the lower troposphere, the
temperature difference between low and high latitudes decreases as the planet warms, creating less wind shear.
The danger
in the current GW is not due to the
difference between a stable climate at average 15oC (your current average
temperature numbers are wrong) and a stable climate at average 20 or 22 or 25oC or what have you, it is due to the extremely rapid rate of change and the
resulting instability and the loss of biodiversity.

The
difference between modeled and observed TSI might be the
result of underrepresented weak magnetic fields
in the Carrington rotation synoptic charts, an uncertainty
in the TSI measurement, or a decline of the global
temperature of the photosphere.
