Climate disruption deniers have been claiming for years now that the global temperature has been cooling down, even though the temperature data clearly shows that it isn’t. Scientists and statisticians have pointed out that, mathematically speaking, the recent reduced warming trend is well within the noise, or put another way, it’s weather, not climate.
A new report by the Associated Press reveals what many of us knew already – the denier’s claims don’t hold water, statistically speaking. The report is intriguing because the AP provided their data to four independent statisticians without telling them what it was, and all four found that the slower warming of the past decade was statistically insignificant with respect to the actual data.

A study published in the journal Environmental Science & Technology has revealed a new and troubling aspect to climate disruption – as glaciers melt, they are releasing persistent organic pollutants like DDT, PCBs, other pesticides, and synthetic musks (chemicals that mask body odor).
The scientists studied the annual sediment layers in a high alpine lake in Switzerland and found that there the annual flux of pollutants varied consistently across all the studied pollutants – the fluxes started low in the 1950s, peaked in the 1960s and 70s, dropped off again in the 1980s, and then rose to a new peak in the late 1990s. But in the case of all the pollutants except for musks, the production of the pollutants ceased by 1986 at the latest, and the musks have been in constant production globally since the late 1980s.
