#urbanclimate — Public Fediverse posts

Ich bin mir nicht ganz sicher, ob Verbrenner gegenüber Stromern einen größeren Output an Wärme haben, der allein durch die Fortbewegung begründet ist – nach dem Energieerhaltungssatz nicht. Dreck in die Luft schleudern sie jedenfalls mehr.

Was allerdings eine deutliche Erhöhung der Wärmelast bewirkt, ist die Anzahl der Klimaanlagen all dieser Fahrzeuge, die ohne nachhaltigen Effekt Wärme erzeugen.

How did Calgary respond to the wet summer of 2025?
Here’s the median summer NDVI map derived from Sentinel-2 imagery.
You can clearly see the Bow River corridor, Nose Hill Park, and the contrast between established tree-rich communities and newer developments.

🌡️ How has Calgary’s April temperature varied over the years?

Using hourly data from the CALGARY INTL weather station (METAR archive, 2009–2025), I analysed how April air-temperature distributions shift from year to year.

Each panel shows the probability density of all measurements for that month, with the red dashed line marking the arithmetic mean.

This work is part of my ongoing, data-driven examination of local climate behaviour using R.

🌡️ How has Calgary’s March temperature varied over the years?

Using hourly data from the CALGARY INTL weather station (METAR archive, 2009–2025), I examined how March air-temperature distributions change from year to year.

Each panel shows the probability density of all measurements for that month — with the red dashed line indicating the arithmetic mean.

This analysis is part of my ongoing, data-driven exploration of local climate behaviour using R.

🌡️ How has Calgary’s February temperature changed over the years?

Using hourly data from the CALGARY INTL weather station (METAR archive, 2009–2025), I looked at how February air-temperature distributions evolve from year to year.

Each panel shows the probability density of all measurements for that month — with the red dashed line marking the arithmetic mean.

🌡️ How has Calgary’s January temperature varied over the years?

Using hourly data from the CALGARY INTL weather station (METAR archive, 2009–2025), I examined how January air-temperature distributions change from year to year.

Each panel shows the probability density of all measurements for that month — with the red dashed line marking the arithmetic mean.

This is part of my ongoing, data-driven look at local climate behaviour using the R programming language.

When we talk about climate change, we often think globally, neglecting the power of cities.

Yet, with over half of the world's population and three-quarters of emissions, cities are crucial in the fight against climate change! #UrbanClimate #Sustainability

Ten years after its well-received publication, 𝙒𝙚𝙖𝙩𝙝𝙚𝙧 𝙞𝙣 𝙩𝙝𝙚 𝘾𝙞𝙩𝙮 is more relevant than ever. In this brand new edition Sanda Lenzholzer draws on current examples in demonstrating how the comfort of the urban environment can be enhanced using modern techniques and new methods. This reference work is an inspiration for all engaged in creating a liveable city. Learn more on our website!
