Of course, logic and ethics had no chance when you were faced with defending it, since the Hockey Stick graph (the only one reproduced multiple times in color in any IPCC summary) was the primary basis for convincing the Media and Policy Makers that immediate action was needed to offset unprecedented warming, obviously caused by unprecedented increase in CO2.

At a stroke, put the end to the claim that the rate of warming was «unprecedented» (thus un-natural cause — man made)

It seem ludicrous that a clear sky that could lose 2 - 3 degrees per hour was able to cause «unprecedented warming».

Indeed, an Australian reporter even suggested that «years of global warming and increased CO2 emissions have caused these trees to grow at an unprecedented rate, providing more fuel for these fires.»

Even if it has been warmer at times during the current and previous interglacials, showing that the forcing is unprecedented, rising and currently overwhelming natural variation can be seen of itself to be sufficient cause for alarm (that it be overwhelming is not quite what the IPCC report states but the more than half post 1950 claim is similar).

Has modern human CO2 emissions caused unprecedented, irreversible and accelerating global warming?

The WMO says the combined causes of this historically unprecedented heat are both natural and human - induced: a strong El Niño − the periodic climate phenomenon in the Pacific − and anthropogenic warming resulting from the rising emissions of greenhouse gases, largely through the burning of fossil fuels, agriculture and deforestation.

If human CO2 causes indisputable, relentless, unequivocal, unprecedented, accelerating and tipping point catastrophic global warming, then why is the U.S. cooling over the last 15 years?

Fueled by seemingly endless United Nations Eco-Summits, the collapse of the Soviet Union, and the rapid rise of dark green nature spirituality in the west, politicians and scientists warmed to the idea that humans are causing unprecedented heating of the planet.

Yet, it is still a widely accepted myth for periods since 1980 - that human CO2 has caused unprecedented temperature increases, far outpacing any previous 20th century warming increases.

The past is full of things we can't explain because no one captured the data, that doesn't mean we are incapable of knowing that GHGs are causing warming today since we now monitor the planet in unprecedented detail.

Unprecedented warm ocean waters from 2014 through 2017 caused the most widespread and damaging coral bleaching event in history, killing millions of corals from the Great Barrier Reef to the Hawaiian Islands.

«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.
