Based on my understanding, it would be correct to say that the effect of doubling CO2 while there is no sunlight is for the temperature drop during the night to be slower — meaning, the minimum and average temperature will be higher than it would have been otherwise.
Following its warmest year on record in 2013 and third warmest in 2014, 2015 remained warm in Australia, with the country experiencing its fifth highest nationally - averaged annual temperature in the 106 - year period of record, with a mean temperature 0.83 °C (1.49 °F) higher than the 1961 — 1990 average, according to the Bureau of Meteorology.
Because climate systems are complex, increases in global average temperatures do not mean increased temperatures everywhere on Earth, nor that temperatures in a given year will be warmer than the year before (which represents weather, not climate).

The combination of these factors means it's much easier to interpolate anomalies and estimate the global mean, than it would be if you were averaging absolute temperatures.
Those extremes will come about more slowly than the rise of mean temperature, but I have seen zero models that suggests a continued rise of global average with no rise of global high.
... Polar amplification explains in part why Greenland Ice Sheet and the West Antarctic Ice Sheet appear to be highly sensitive to relatively small increases in CO2 concentration and global mean temperature... Polar amplification occurs if the magnitude of zonally averaged surface temperature change at high latitudes exceeds the globally averaged temperature change, in response to climate forcings and on time scales greater than the annual cycle.
More than 95 % of the 5 yr running mean of the surface temperature change since 1850 can be replicated by an integration of the sunspot data (as a proxy for ocean heat content), departing from the average value over the period of the sunspot record (~ 40SSN), plus the superimposition of a ~ 60 yr sinusoid representing the observed oceanic oscillations.
Global warming does not mean no winter, it means winter start later, summer hotter, as Gary Peters said «The global average surface temperature has risen between 0.6 °C and 0.7 °C since the start of the twentieth century, and the rate of increase since 1976 has been approximately three times faster than the century - scale trend.»
Surface temperatures in parts of Europe appear to have have averaged nearly 1 °C below the 20th century mean during multidecadal intervals of the late 16th and late 17th century (and with even more extreme coolness for individual years), though most reconstructions indicate less than 0.5 °C cooling relative to 20th century mean conditions for the Northern Hemisphere as a whole.
eg2 Similarly there are seasonal temperature changes such that in winter the average temp is ~ 10 - 20 degrees lower than the mean, and likewise the northern winter CO2 air concentration is 5ppm lower, thus changing the energy flow balance in winter vs summer and day vs night & north vs south.
Three of the four global average temperatures indeed are decreasing in their trends (although the actual global mean temperatures are still warmer than the previous decades).

But mean temperatures are expected to rise faster than the global average, decreasing crop yields, deepening poverty.
So while it was a generally warmer (and drier) than usual winter it also wasn't the warmest ever, with the official NIWA statement being «The nation - wide mean temperature was 1.2 °C above the winter average, based on NIWA's seven - station temperature series, making this the warmest winter on record since 1909.»
It's by no means obvious that any «more natural» average temperature would be better than some less natural one.
Continuing the planet's long - term warming trend, globally averaged temperatures in 2017 were 0.90 degrees Celsius (1.62 degrees Fahrenheit) warmer than the 1951 to 1980 mean.
A «positive» anomaly means the temperature is warmer than the long - term average, a «negative» anomaly means it's cooler.
Even the standard radiative GHG effect of 33 or something K is on very shaky ground, i mean the explanation for higher than black - body temperature of the surface (the average) using only radiative «forcing».
It is for these reasons that the concept of an «average global temperature» can be seen to have no more than a political meaning.
When the earth's temperature rises on average by more than two degrees, interactions between different consequences of global warming (reduction in the area of arable land, unexpected crop failures, extinction of diverse plant and animal species) combined with increasing populations mean that hundreds of millions of people may die from starvation or disease in future famines.
The warm anomalies in June lasted throughout the entire month (increases in monthly mean temperature of up to 6 to 7 °C), but July was only slightly warmer than on average (+1 to +3 °C), and the highest anomalies were reached between 1st and 13th August (+7 °C)(Fink et al., 2004).
I am still waiting for word on what the global temperature anomaly for the month was, but I suspect it will be fairly close to normal, which means that on average the temperature of the Earth will come in at ~ 12.0 °C which is 4 °C colder than it will be in 6 months from now, but because of how they talk about temperature, I will be the only one pointing out the difference between the actual temperature and the anomaly temperature.
The steady increase in global temperatures, including average temperatures in Australia, means that even when rainfall is at or near the historical average, conditions are drier than before because evaporation rates are higher.

The link between a regional climate variable such as mean temperature and the average behaviour of a sample of trees is one step more statistical than the link between local weather and an individual tree.
Actually, a warmer world means higher levels of humidity, less drought and a shrinking of deserts, as in the Sahara circa 4,000 - 6,000 years ago during the era known as the climatic optimum when temperatures averaged some 2 degrees higher than today's.
This means that if you are younger than 38 years old, you've never experienced a year in which the global average surface temperature was below average.
They point out that if we assume the data are normally distributed, then the July 2010 average temperature anomaly value was more than 4 standard deviations above the July mean (and they have a lovely graph to emphasize it):
So over the full course of a day the average temperature is lower on cloudy day than on clear days and why tropical deserts have the highest mean annual temperature of any climate type.
But mean temperatures are expected to rise faster in the continent than the global average, decreasing crop yields and deepening poverty.
When someone talks about climate change and warming in particular it would only make sense if they meant that the average temperature accross the earths surface is warmer than it used to be at some point in the past.
In contrast, meteorological data collected from three nearby coastal stations (Brevoort Island, Cape Dyer, and Resolution Island) between 1950 and 1992 indicated that the mean minimum and maximum air temperatures for the month of April are normally 10 - 20 °C cooler than the averages we recorded at our camp.
but this occurred under significantly different orbital forcing conditions» This is to make us believe that a global mean temperature could drive the melting or calving of the Greenland; but the Eemian diminution of the Greenland ice cap is by no means related to an average global temperature but to the local summer insolation that during the last interglacial was up to 30 W / m ² to 60 W / m ² stronger than today's.
