Sensor check delays India’s record heat confirmation

A recent temperature reading in India raises questions about the accuracy of extreme heat measurements.

On Wednesday, a station in a Delhi suburb recorded 52.9 degrees Celsius (127.2 Fahrenheit), potentially breaking the national record.

However, the India Meteorological Department (IMD) flagged the reading as an outlier compared to other stations and is investigating possible sensor errors.

This incident underscores the importance of meticulously verifying temperature readings, especially for climate change monitoring.

Accurate data allows scientists to understand how the planet is warming and develop appropriate responses.

The World Meteorological Organization (WMO) plays a crucial role in this process, maintaining a global archive of weather and climate extremes.

Their verification process is thorough, taking months or even years to ensure the accuracy of record-breaking claims.

This includes identifying and correcting errors caused by faulty measuring equipment.
