Excited to share our new app Thermal Trace!

Thermal stress = health impacts of exposure to extreme thermal conditions (heatwaves, cold spells)

Use Thermal Trace to monitor heat & cold stress globally (five days behind real time) & explore changes over time 🥵🥶

During the heatwave in western Europe in August, maximum feels-like temperatures reached up to 45°C in France, 47°C in Portugal, and 49°C in Spain – the threshold for ‘extreme heat stress’ is 46°C 🥵

Based on insights from Thermal Trace, our new app for monitoring heat and cold stress worldwide 🔗⬇️

🌡 Third-warmest August globally, 1.29°C above pre-industrial level, 0.49°C above the 1991–2020 average for the month. Western Europe saw major heatwaves, mostly in the Iberian Peninsula and southwest France. Third-highest sea surface temperatures on record at 20.82°C.

Met Office stats confirm summer 2025 is officially the warmest summer on record for the UK.

The UK’s mean temp of 16.10°C surpasses the previous record of  15.76°C and pushes the summer of 1976 out of the top 5 warmest summers.

Visited Helios at Basildon Park - a 7 m installation of the Sun hanging among the trees in the grounds, and with soundscapes that are real recordings from space. 1 cm of the image on the sphere represents 2000 km on the surface of the Sun! 🤩☀️✨ #SciArt

An interesting comparison of this summer so far with the UK’s infamous summer of 1976 ☀️🥵 This year’s June heat was more widespread across Europe + the UK saw larger temperature anomalies this June, but drought in 1976 was more prolonged and widespread with more extreme water use restrictions 💧
