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 🥵🥶

Maps and charts shape how we see the climate crisis. Visualising Climate asks how we can design visuals that inform without oversimplifying and inspire action with integrity.
Imagine new ways forward.

Several international organisations all released their global temperature updates today. In addition to our @copernicusecmwf.bsky.social Global Climate Highlights, here’s a thread with resources from WMO, the Met Office, Berkeley Earth, NASA, NOAA and more 📈🌡️⬇️
Global mean temperature 2025: 1.44 ± 0.13 °C above the 1850-1900 average, based on a synthesis of eight international datasets.
2025 was the second or third warmest year on record. 2024 remains the warmest.
That makes the past 3 years are the 3 warmest years on record.

SSHWS category is assigned using ONE value: the maximum wind 10 meters above the ocean surface averaged over 1 minute. A hurricane is not a point. Its size (extent of its wind *field*), forward speed, rainfall, potential storm surge, and the landscape it traverses all factor into its impacts. [3/5]

As a meteorologist with a 20-year obsession with hurricanes (thanks to Charley in 2004), who has done research and diagnostics on tropical cyclone forecasting and now works in climate science / learning about attribution, this is a very interesting thread about Hurricane Melissa ⬇️🧵🌀
So, I hate to be this guy, but as the director of Yale’s new program on attribution science (!?), uh, most of the commentary on Bluesky about Hurricane Melissa and climate change has been… not quite right
