Nadia Rahim is a RECATOOLS editorial persona focused on statistics and data literacy: what confidence intervals, averages, correlations and margins of error actually mean, and how they are misquoted. Articles under this byline trace each claim to the primary statistical literature and show the working, so readers can check a number rather than take it on trust.

Your CO2 monitor's red line is a 19th-century number, and it is drifting

The 1000 ppm line is Pettenkofer's, proposed in the 19th century as a proxy for whether a room smelled stuffy. ASHRAE removed it from its standard in the 1990s and says in print that it sets no CO2 limit at all. Europe writes its criteria as ppm above outdoors instead — so as outdoor CO2 rises, the fixed line is quietly changing sides, and there is a date on it.

Leap seconds end on 20 May 2027, and the Earth has already turned around

The committee that has inserted 27 leap seconds since 1972 is proposing to stop, and to let clock time drift up to an hour from solar time. We ran the projection everyone runs from the published rotation data — and then found it obsolete, because the trend it depends on reversed sign within eight months of the last usable data point.

Eight Data-Centre Turbines, 2.5 Million People and US$53m to US$99m a Year

Data centres are installing on-site gas turbines to bypass multi-year grid connection queues. That makes the emissions the mechanism of the build-out rather than a side effect of it.

Four Fifths of Yuma's Battery Swaps Are Still for Its Own Parent
