The latest IPCC report on climate change notes that our society will likely need net negative emissions by the end of the century to avoid a 2 degree C warming.

Considering all the short - term factors identified by the scientific community that acted to slow the rate of global warming over the past two decades (volcanoes, ocean heat uptake, solar decreases, predominance of La Niñas, etc.) it is likely the temperature increase would have accelerated in comparison to the late 20th Century increases.

Achieving a binding agreement by Paris next year in order to prevent runaway climate change later this century is looking far less likely than when we arrived in Lima at the end of November.

Schmidt assumes it did but the PDO record suggests that it likely did not, in which case Schmidt's argument that late - century warming must have been caused by CO2 collapses.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

Nevertheless, it seems likely that a CO2 concentration in the range 500 to 900 ppm might produce a temperature rise of at least 2 °C from the late 19th century that could be problematic for humankind; (7) The potential negative impact on humanity has been exaggerated; (8) The only alternative to rising greenhouse gas concentrations is to immediately and sharply reduce CO2 emissions — whether this averts a «pending disaster» is not well understood; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 probably resulting in some warming; (10) Such reductions in CO2 emissions are neither technically feasible nor economically affordable, and would necessitate inadequate energy supply to a growing world population that is increasingly industrializing, leading to worldwide depression.

But, you're making the same claim that this is the cause of the pause, when it's more likely that a positive AMO and PDO both simultaneously warmed the Northern Hemisphere at the end of the 20th century, the History of the late 30's had the same high temps (and melted Arctic), which were followed by cold PDO phase.

Since the LIA was about a degree cooler than late 20th century and it can take the oceans 300 years or more to recover by 1 degree, some portion of the warming is «likely» due to a return to «normal».
