Take theClimate Science Challenge
What are you afraid of?
Premise: But what about before the 1990 benchmark? Maybe the last 25 years (inclusive) are just a pause in global warming.
By again examining our multiple datasets, from 1931 to 1979 the temperature datasets show no global warming either (the RSS and UAH are satellite datasets that only began in 1979, so cannot be included in this graph). No pronounced benchmark is apparent or has been identified by the adherent-establishment, so no range lines are offered, but it is still obvious that the entire period presents a consolidation in relation to the zero anomaly line. This means that over the 84 years inclusive from 1931 to 2014 only one period of 11 years (1979-1990) produced a slight increase in the global temperature. Carbon dioxide went up from 280 PPM to 400 PPM, but for only 13% of that time was there any rise in the global temperature. 11 of the last 84 years. 13%. Two consolidation periods comprised 73 of the last 84 years – 87%. In fact, the appropriate view is that the trend for the last 84 years has been consolidation, with an 11 year “pause” of slight warming thrown in the middle.
Question: What anthropogenic global warming?
Conundrum: At the most basic level, the global warming controversy is solely about the relationship between global temperature and atmospheric carbon dioxide content. Every other concern is peripheral and conducive on this relationship. The empirical evidence of 9 and 13 temperature datasets suggests that there is no direct relationship between the two, or if there is, it is that a rising CO2 PPM produces a consolidating global temperature, with an odd 13% blip thrown in.
Conclusion: According to publicly available global temperature datasets produced by the adherent-establishment there is no anthropogenic global warming (their own datasets contradict their own claims).
