ET EnviroTruth Environmental data, explained
Climate · Real data, 1940-present

What the long-term record actually shows.

We pull 85 years of ERA5 reanalysis from Open-Meteo at build time and chart it city by city, so you can read the trend without anyone framing it for you.

Topics

Explainers, not opinions.

EnviroTruth covers the same environmental subjects you'll find debated everywhere else — only with the data laid out and the rhetoric stripped out.

Every climate-data page sits on top of a real, publicly licensed dataset, refreshed each build. We name our sources, we name the limits, and we don't try to land a punch. The other topics (water chemistry, biotech food, plastics, direct-action cases) are written the same way.

Where to start

Single ripple on still water surface
Water

Chlorine in drinking water

Why chlorination is standard practice, what the regulated thresholds are, and what disinfection by-products actually are.
