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.

Data Centres Moved 175km From The Cities, And Power Is Why

JLL finds hyperscale campuses planned for 2026-28 sit almost four times further from EMEA hub cities than those delivered since 2022. Training can follow the electricity. Interactive serving cannot.

Annual Rainfall Will Not Size Your Tank

Singapore and Manila are within five per cent of each other on annual rainfall, and their driest months are 112 mm and 8 mm. Through the same roof, demand and tank, that turns a 10,000-litre tank meeting all of a household's demand into one meeting 69.3 per cent — and quadrupling it buys back only 2.4 points, because storage moves water through time and cannot create rain that never fell.

What Does "Plant a Tree to Offset It" Actually Buy?

Carbon calculators end by translating your emissions into trees, and the unit that translation produces is the tree-year — one tree working for one year, not a headcount. Planted today, the 47.62 trees our tools quote against 1,000 kg deliver 20 per cent of it in year one and only pass the target during year three. Keep emitting and one planting never catches up: the deficit settles at exactly 2.00 years and stays there.

Flying Against Driving, and the Units Nobody Checks

Both confident answers to this question are built on comparing a per-passenger figure with a per-vehicle one. Divide the car by its occupancy and the answer stops being yes or no: it is 2, the number of people who need to be in it. We also declined to rank solo driving against flying, because that comparison flips on an assumption we cannot defend. Rail beat everything by a factor of nearly four.

Google Is Building a $15 Billion Campus in a City That Rations Water

Google's $15 billion data centre campus near Visakhapatnam faces a High Court petition and three environmental-court cases over water and a wildlife sanctuary 860 metres away. The city already rations water. The campus's own draw has never been published, which is why every party is arguing from a figure the others cannot check.

Singapore Cannot Say How Long Finished Solar Panels Wait for the Grid. Nobody Records It

Asked for the average time between a completed solar installation and grid connection, MTI said the data does not exist because installers are not required to report completion dates.
