This article published on Space.com does show the 1500 year solar cycle does indeed affect world wide weather and with the last mini-ice age just 600 years ago it would seem logical that we are getting nearer to a warming temperature peak and thus world wide avgerage atmospheric temperature that is quoted so often «Should Be Rising» now and for the next 100 to 300 years.

Moreover, the seasonal, regional, and atmospheric patterns of rising temperatures — greater warming in winters than summers, greater warming at high latitudes than near the equator, and a cooling in the stratosphere while the lower atmosphere is warmer — jibe with what computer models predict should happen with greenhouse heating.

I was under the impression that the atmospheric near surface temperatures have been measured in the past using thermometers.

• You are possibly aware that the land surface temperatures are not actually of the land, but the near surface air temperatures, and I seem to recall that in the past you believed that they are strongly influenced by atmospheric CO2 levels which you claimed are evenly mixed globally including at ~ 3,000 metres altitude at Moana Loa.

Plasmas have uncoupled temperatures of multiple species, while, gasses near atmospheric pressure have well coupled temperatures.

A National Research Council panel was convened to examine observed trends of temperature near the surface and in the lower to midtroposphere (the atmospheric layer extending from the earth's surface up to about 8 km).

The variability is due to day - to - day variations in temperature, strength of the surface - based temperature inversion, atmospheric humidity, and the presence of «diamond dust» (near - surface ice crystals).

Does the atmospheric pressure, no GH gases, effect the overall equilibrium temperature of the near surface of a planet?

We've only been keeping thermometer records since 1880, and satellites have only been measuring near - surface atmospheric temperatures since the mid-1970s.

It will always come back to the fact that, nominally, it's all about the Sun — e.g., Farmers Almanac is predicting another cold wet winter despite the increase over the years in the amount of atmospheric CO2: No region will see prolonged spells of above - normal temperatures; only near the West and East Coasts will temperatures average close to normal.

(For a discussion of the limits of IPCC, see, Brown, 2008) In fact observations of actual greenhouse gas atmospheric concentrations, temperatures, and sea level rise are near or exceeding the IPCC worst - case predictions.

We use measured global temperature and Earth's measured energy imbalance to determine the atmospheric CO2 level required to stabilize climate at today's global temperature, which is near the upper end of the global temperature range in the current interglacial period (the Holocene).
