🇨🇦 We're back from #Québec! We had an amazing time on the #MajorExcursion, exploring the benefits and the problems of Québec's #EnergyTransition 💧🌱 Read all about our lessons learned and scroll through some snapshots on our blog: 🔗 www.geo.lmu.de/geographie/e... #geosky #sustainability
A slide, saying: major excursion Québec: exploring the environmental and social impacts of energy transition. Underneath, there is a collage of four images: a skyline view of Totonto, a large red sign on the highway towards Maagami, some sticks assembled to the structure of a tipi, and our students standing in front of a reservoir, wearing orange vests and blue helmets.

Where better to understand #Geography than out in the field? 🌍 Greetings from #Montréal - just one stop on our #Québec excursion! In Québec City, @gampedavid.bsky.social & his students learned about the city's water management from Dr. Sonja Behmel💧Stay tuned: insights & impressions coming soon!
View of Montréal’s skyline from Mount Royal: lush green trees and shrubs in the foreground contrast with the blue-grey cityscape in the background, where skyscrapers and buildings stretch across the horizon. Students sit on the grass on a sunny day, listening to Dr. Sonja Behmel discuss challenges and solutions in managing the Lac St-Charles catchment, the main drinking water source for Québec City.

Benedikt Hartweg tackles uncertainties in #forest biomass estimates by combining satellite data, forest models and #MachineLearning. The method improves flexibility and accuracy - successfully tested in tropical regions, next step: scaling with #ESA #BIOMASS.

We had a fantastic time at @esa.int's Living Planet Symposium #LPS25 in Vienna! This year, it was all about how we can use remote sensing for improving 𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝗮𝗰𝘁𝗶𝗼𝗻 𝗮𝗻𝗱 #𝘀𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗶𝗹𝗶𝘁𝘆. More info on our blog: www.geo.lmu.de/geographie/e...

Here's what we presented 👀🧵

Thanks James! We'd be so happy to see more projects like this! We already have the infrastructure - so why not use it to the fullest? 🤩

🗺️ The outcome: dynamic, street-level heat maps that support targeted climate action - essential for heat protection, especially for vulnerable groups. More greenery, cooling spots, better planning – solid data help us develop tailored solutions that benefit all! #climatechange #urbanheat

But temperatures vary by time of day. Our Bachelor student Simon Schnitzler developed a method to normalize the mobile sensor data. He found that there are critical heat islands along Dachauer & Leonrodstraße, and cooler zones near Olympiapark.
The map that Simon Schnitzler created from the data collected with the garbage truck sensors. It shows the Munich area south of Olympiapark. The measuring points of the garbage trucks are coloured red, orange, yellow, light and dark green, depending if the spot was cooler (green) or hotter (red) than the average city temperature on that day. Measuring was conducted from July 30 to August 1 2024. Two partial images of orange garbage trucks, with the small white sensors on the roof circled in red.

🌡️ Some parts of #Munich heat up more than others – and this can be dangerous! Thanks to garbage trucks turned climate sensors, Munich can now implement targeted heat mitigation measures where they are needed most. Read how: www.geo.lmu.de/geographie/e... #UrbanHeat #ClimateAction #Geosky 🧪

Anthropogenic #ClimateChange 🌎 🌍 drove increases in UK summer heat 🌡️ mortality. Yet, without aerosol cooling this increase would have been even more drastic! Check out our #ClimateAttribution & #Epidemiology 📊 study in @thelancetplanet.bsky.social, led by Kai Wan for more!

Colored line-plots showing the summer temperatures (May-September) from 1850-2100 for the UK (A) and the corresponding heat-related mortality (B) for the CanESM5 large ensemble (DAMIP archive). Colors refer to the applied factual (All, green) and counterfactual (Natural forcings only, blue; anthropogenic greenhouse gases only, red; and anthropogenic aerosols only, purple) forcings. Future projections are based on the SSP-245 pathway. Solid lines represent the mean of the large ensemble, i.e., the forced response. Shading in both panels refer to the 95% empirical confidence interval representing both, the uncertainties of the health risk function and natural climate variability (assessed as spread over the 10 members of the SMILE).

🌍💪 This is hands-on #Geography in action! In our Freilandpraktikum, students assemble meteorological stations, calibrate sensors & collect field data (chloropyll levels, soil samples & more!) – all for their own research projects. 💡Real data, real questions, real science!
#ClimateScience #science🧪
Two students are assembling a meteorological station. A soil sample, taken during our Freilandpraktikum. What do you think: Which soil types does this sample reveal? Field work from a bird's eye view: Our students are assembling meteorological stations.

💡𝗪𝗵𝘆 𝗶𝘁 𝗺𝗮𝘁𝘁𝗲𝗿𝘀:
Coordinated policy design is essential to avoid potential trade-offs!

⚠️ 𝗕𝘂𝘁: The negative health impact of aerosols was not studied here, but (very likely) exceeds their positive effect through net cooling by a great bit.
nexuslmu.bsky.social
The study modeled heat-related mortality in Great Britain from 1850–2100 and found:

• Aerosol-driven cooling masked hundreds of heat-related deaths in the 20th century
• As aerosol levels decline, this effect fades
• Under a mid-range emissions scenario, heat-related deaths could rise 2–6× by 2100.
