#Arctic climate rankings are now in for June 2026: https://zacklabe.com/archive-2026/ Unfortunately, still no new data available for sea-ice volume and thickness. #SciComm #DataViz #OpenScience #OpenData

My next 'climate viz of the month' blog is posted: https://zacklabe.com/climate-viz-of-the-month/ which takes a look at the effects of different regional warming when calculating the global temperature anomaly record, along with a June update for Arctic climate. #DataViz #SciComm #OpenScience #OpenData

Today Microsoft #Excel differences on Windows to macOS (missing menus just ribbon) got me thinking: can I not just run a #SpreadSheet in the #Linux #terminal for basic data work and visualisation? I want something akin to the original text only #Lotus123 (which I used for school work on DOS), but ideally with in-terminal graphics for #DataViz. There is https://github.com/andmarti1424/sc-im (must self compile, not trivial), several apparently abandoned tools like https://www.syntax-k.de/projekte/teapot/ - and multiple vibe-coded rust tools I'd rather avoid... Suggestions please?

🌳 Is Calgary actually as green as it looks? While open lawns (28.6% citywide) give Calgary a visual "green appearance", dry summer conditions quickly strip unirrigated grass of its cooling capacity. Meanwhile, true cooling infrastructure — dense and sparse tree canopy — accounts for only ~17%. To quantify structural heat risks, I introduced the Solid-to-Tree Ratio index across 193 residential communities: 🔹 Critical Deficit: Downtown Core (56.2) and Beltline (24.6), where hard surfaces outnumber tree canopy by tens of times. 🔹 Suburban Pressure: New communities like Redstone (23.8) and Seton (20.8) feature high-density lots with minimal mature shade. 🔹 Ecological Buffers: River valley communities like Discovery Ridge (0.5) and Wildwood (0.6), where canopy exceeds concrete. 👇 Link to the full study and interactive dataset: https://www.datastory.org.ua/calgarys-microclimatic-anatomy-what-lies-beneath-the-citys-green-appearance/ #Calgary #YYC #DataScience #GIS #RStats #RemoteSensing #UrbanHeat #DataViz #SpatialAnalysis #MachineLearning #GreennessOfCalgary #FOSSGIS #Alberta #Canada

🌳 Quantifying Calgary’s Microclimatic Imbalance: The Solid-to-Tree Ratio To evaluate the structural heat load across Calgary's communities, I calculated the ratio of high-thermal artificial surfaces to cooling tree canopy: Solid / (Park + Forest), based on my 2025 satellite land cover model (LULC v6.0). Why this ratio matters: 🔹 Thermal Stress Indicator: It measures how many square meters of heat-absorbing surfaces (asphalt, concrete, roofs, bare soil) exist for every square meter of tree canopy. 🔹 Spatial Inequality: While mature western neighborhoods maintain ratios between 1.5 and 4, eastern and peripheral zones reach values from 10 to over 50. 🔹 Evidence-Based Planning: It moves the discussion from generic averages to identifying exact spatial boundaries where microclimatic mitigation is most needed. Note: The map uses a logarithmic scale. #Calgary #YYC #DataScience #GIS #RStats #RemoteSensing #UrbanHeat #DataViz #SpatialAnalysis #MachineLearning #GreennessOfCalgary #FOSSGIS #Sentinel1 #Sentinel2

📊 Beyond Averages: Spatial Heterogeneity in Calgary (LULC v6.0) Averages mask reality. To capture ecological stratification across Calgary's residential communities (excl. major parks/building-out and industrial zones), I combined Violin + Box Plots: 🔹 Solid (Impervious): Median ~67% (IQR 55–74%). High-thermal non-vegetated surfaces are a systemic structural feature across nearly all neighborhoods. 🔹 Park vs. Lawn (Canopy vs. Turf): Park median (~20%) doubles Lawn (~10%). A long upper tail (>50%) highlights spatial inequality in tree cover. 🔹 Forest & Water: Near 0% for 95% of communities, but sharp needles (up to 25% forest, 16% water) mark outliers with lakes or remnant woods. 💡 Takeaway: Calgary isn't homogenous—microclimatic comfort heavily depends on geographic boundaries.

I built a free world railway atlas as a hobby. This chart ranks the fastest train in every country by what it actually averages end to end — not headline top speed. The US Acela: 110 km/h, slower than the best trains of 32 countries. China's Beijing–Shanghai: 307 km/h. All 101 countries, with method: https://trainrouter.com/fastest-trains #trains #rail #dataviz #maps

The weathers, they are a-changing. We can make sense of pattern evolution. I am starting a thread about Europe's new #climate conditions. 🧵 (You may read stories in the "ALT" descriptions.) #trend #heatwave #dataViz #chart #loess #linearRegression #statistics #France #football #WorldCup #Maignan #history #coloniality #weather #summer #Europe #climate #climateChange #globalWarming
