The upshot is that, starting with my kitchen 'nerve-centre' and then spanning into other rooms over time, these various crises have resulted in what I call #strata.
The lowest strata is #DIY mask experiments and making. Above that is the first attempts at #HeatMitigation. Then there is #AirQuality mitigation, and then some blending of these in upper strata depending on access to materials or new approaches I can try without risking violating my #lease.
Except, of course, it turns out there is always a catch.

I've talked about some of this on Mastodon before, such as creating #coroplast and #blackout material #WindowBlocks to prevent the heat from our long 53°N summer days getting into my unit (circa 2021) or adding thermal window film to reduce heat even more (circa 2025) without simultaneously creating a dark and depressing #bunker-effect for the entire summer.
Doing all of this required various materials, time and of course, money. While all these (and other) mitigations were experiemented with and created/installed over several years, which spread out the up-front cost, the irony is not lost on me that these approaches have culmulatively cost as much as as least two in-window #AirConditoners would. 🙄

‼️ New paper! Cities are heating up, but smarter green spaces can help cool them down 🌳 Our new study shows how trees, coverage & better distribution of urban green spaces can significantly reduce heat and improve access!

Trees may not cool cities during heat waves as much as previously thought
A study found that the heat mitigation benefit of trees is significantly hampered in extremely hot conditions.
#Trees take precautions under heat stress to maintain moisture and avoid dryness by holding onto their sap. This reduces transpiration flow and thus their ability to cool—something overlooked in current climate forecasts.

Useful study on Sydney Science Park Summer Air and Soil Temperatures 2023-24. This establishes a microclimate baseline of air and soil temperatures at former open farming land in #Penrith Municipality in western Sydney. This area will be subject to residential development, but the data will allow the developer to implement 40% tree canopy and urban heat mitigation strategies using blue-green infrastructure, climate responsive design and cool materials.
Recommendations:
1. Develop and action robust environmental monitoring strategy
2. Make SSP a ‘Sponge City’ to assist plant growth and cooling
3. Harvest stormwater for plant irrigation
4. Support good plant growth, ameliorate existing soils and keep topsoils cool
5. Use structural cells for optimal tree growth
