The Almeria subsoil heats up and scientists install sensors

Published on May 17, 2026 | Translated from Spanish

A team of scientists in Almería has detected an unprecedented climatic phenomenon beneath our feet. Variations in temperature and humidity in the subsoil are altering underground ecosystems and compromising water resources. To understand it, they have installed sensors in caves and aquifers. The first data reveals that the deep soil is warming faster than expected, a change linked to human activity and global warming that threatens local agriculture and biodiversity.

Sensors in caves: the technology monitoring hidden heat 🌡️

Experts have deployed a network of temperature and humidity sensors in cavities and aquifers in the region. These devices record real-time data to analyze how surface heat penetrates deep layers. Initial models indicate that thermal transmission is accelerating, possibly due to soil compaction and reduced vegetation cover. This information is key to adjusting agricultural forecasts and understanding the carbon cycle, as a warmer subsoil releases stored CO2.

The Earth has a fever and we have no thermometer at home 🤒

It seems the planet has decided to turn on central heating without warning. While scientists rush with their sensors, Almería's farmers might need to start watering with ice cubes. The curious thing is that for decades we have been looking at the sky to talk about the climate, and it turns out the real drama is in the basement. Soon we will see potatoes asking for air conditioning and earthworms with umbrellas.
