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.

Overall, the energy intensity of the global economy would need to drop by a yearly average of 2.5 % up to 2050 — three - and - a-half times greater than the rate over the past 15 years.

Most of the observed increase in global average temperatures since the mid-20th century is very likely [greater than 90 % likelihood] due to the observed increase in anthropogenic greenhouse gas concentrations.

In the opinion of the panel, the warming trend in global - mean surface temperature observations during the past 20 years is undoubtedly real and is substantially greater than the average rate of warming during the twentieth century.

Based on current knowledge, however, it appears that achieving a high probability of limiting global average temperature rise to 2C will require that the increase in greenhouse - gas concentrations as well as all the other warming and cooling influences on global climate in the year 2100, as compared with 1750, should add up to a net warming no greater than what would be associated with a CO2 concentration of about 400 parts per million (ppm).

Even on the global scale, the annual, global - averaged radiative forcing predicted by the models is significantly greater than has been observed based on the accumulation of Joules in the climate system.

In fact the Mauna Loa or global CO2 rise is much faster than linear... the differences between the mauna loa / global are negligible for the purpose of radiative transfer, and the difference in average CO2 concentration between an «average global» data - set and the Mauna Loa record since 1980 (for monthly values) is only 0.65 ppm (and with a correlation coefficient r greater than 0.99) indicating that the Mauna Loa record is representative of global - scale CO2 concentration as you'd expect with a well - mixed gas.

Paragrap 17 «Notes with concern that the estimated aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined contributions do not fall within least - cost 2 ̊C scenarios but rather lead to a projected level of 55 gigatonnes in 2030, and also notes that much greater emission reduction efforts will be required than those associated with the intended nationally determined contributions in order to hold the increase in the global average temperature to below 2 ̊C above pre-industrial levels by reducing emissions to 40 gigatonnes or to 1.5 ̊C above pre-industrial levels by reducing to a level to be identified in the special report referred to in paragraph 21 below;»
