In fact average IQ cannot change. The average IQ of humanity is always 100, because that is the definition of the IQ scale.[[Special:Contributions/108.162.216.129|108.162.216.129]] 01:15, 15 March 2015 (UTC)

"IQ" per se is simply what IQ tests measure. There's no law that says any specific test that purports to be the best measure of IQ is the gold standard. In the US and many (perhaps most) other English-speaking countries, the Wechsler and Stanford-Binet scales are the most popular. The Wechsler Adult Intelligence Scale is the IQ test most commonly used (for adults) by neuropsychologists. It's re-normed every few years (e.g., WAIS-III becomes WAIS-IV, then WAIS-V, etc.). In "re-norming" each question is studied and perhaps refined, some are dropped, and new questions--sometimes entirely new subtests--are added. The method of calculating the IQ is often tweaked as well. Re-norming involves administering versions of the test to thousands of people and using statistics to determine the one to keep. Obviously the same pool of test-takers is not used every time in a process that goes on decade after decade. It's not unusual for test questions to become more difficult and what's considered to be an average score to be a bit higher in the new edition than in the old. This has been interpreted to mean that people are getting more intelligent, but that's not the only possible explanation. (Also, the test is not normed on "humanity" but on a tiny subset of earth's humans.) Oh, and your IQ is not a number carved in stone, so to speak, but a best-guess that falls within the range of scores you'd be expected to earn if (theoretically) you took the same test multiple times.[[User:Npsych|Npsych]] ([[User talk:Npsych|talk]]) 10:20, 2 December 2015 (UTC)
 
  
 
If there is reason for climate change it is almost certainly due to the destruction of trees. Any ridiculous assertions about carbon dioxide can not be confirmed or denied and the political machinations about carbon dioxide stem from Margaret Thatcher's war on the coal miners in Britain.
