Warmer than

This translates into an
average temperature rise of 4.3 C
over land in the northern hemisphere where most of the world's population lives, and even more in urban areas.
Global mean
temperatures averaged over land and ocean surfaces, from three different estimates, each of which has been independently adjusted for various homogeneity issues, are consistent within uncertainty estimates
over the period 1901 to 2005 and show similar rates of increase in recent decades.
Temperature changes relative to the corresponding
average for 1901 - 1950 (°C) from decade to decade from 1906 to 2005
over the Earth's continents, as well as the entire globe, global
land area and the global ocean (lower graphs).
With the anthropogenic perturbation likely to be around 2C and maybe more in the next 100 years (that's a global
average, it will be much more
over northern hemisphere
land where we actually live), there are simply no comparable sources of natural variability, and the historical record shows that such
temperatures have not been approached in the last 2000 years.
«The combined
average temperature over global
land and ocean surfaces tied with 2010 as the highest on record for April, at 58.09 °F (14.47 °C) or 1.39 °F (0.77 °C) above the 20th century
average.»
Thus, small changes of global
average air
temperature are associated with very large changes in some regions, particularly
over land, at mid - to high latitudes, in mountain regions.
Temperatures over land and ocean have gone up 0.8 ° Celsius (1.4 ° Fahrenheit), on
average, in that span:
The combined
average temperature over global
land and ocean surfaces for April 2016 was 1.98 °F above the 20th century
average — the highest
temperature departure for April since global records began in 1880.
Figure 1 shows the change in the world's air
temperature averaged over all the
land and ocean between 1975 and 2008.
So for us people with some engineering experience, that gives us an intuitive feel for why
temperatures are hotter
over land than what is in the
average SST data.
However, the critical threshold R C is independent of ɛ, and thus the calculation depends only on relatively robust
averaged values of precipitation, net radiation,
average temperature difference between
land and ocean, specific humidity
over ocean, and the natural constants ρ, L, and C p.
The annual anomaly of the global
average surface
temperature in 2014 (i.e. the
average of the near - surface air
temperature over land and the SST) was +0.27 °C above the 1981 - 2010
average (+0.63 °C above the 20th century
average), and was the warmest since 1891.

average annual surface air
temperature anomaly (+3.6 °F / 2.0 °C relative to the 1981 - 2010 baseline)

One reason for this is that «global
temperature» varies significantly
over the months of the year due to seasonally varying Earth / sun geometry and the greater
land mass in the Northern Hemisphere, so that any global
average of absolute
temperature, not anomalies, will be considerably higher in NH summer than SH summer, and this will be true even in an unchanging climate.
Average air temperature over the land and sea surface was 0.56 degrees Celsius above the long - term average, tied with 2010 as the joint warmest year on

Over the same period, the globally and annually
averaged land and sea surface
temperature (HadCRUT3) increased by 0.7 °C.
The fact this is seemingly not fully recognized — or here integrated — by Curry goes to the same reason Curry does not recognize why the so called «pause» is a fiction, why the «slowing» of the «rate» of increase in
average ambient global
land and ocean surface air
temperatures over a shorter term period from the larger spike beyond the longer term mean of the 90s is also meaningless in terms of the basic issue, and why the
average ambient increase in global air
temperatures over such a short term is by far the least important empirical indicia of the issue.
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..
Our results show that the
average temperature of the earth's
land has risen by two and a half degrees Fahrenheit
over the past 250 years, including an increase of one and a half degrees
over the most recent 50 years.

The earth's

The period of increased warming from 1987 to 1997 loosely coincided with the divergence of the global
average temperature anomalies
over land, which are derived from observation station recordings, and the global
average anomalies in sea surface
temperatures.
«The combined
