Reply to comment by YouJustSaidButFuck in Planting more trees could axe summer deaths by a third. Modelling of 93 European cities finds that increasing tree cover up to 30% can help lower the temperature of urban environments by an average of 0.4°C and prevent one in three heat deaths as a result. by MistWeaver80

There’s way more untapped vertical space in single-family neighborhoods in desirable cities even below five stories than there is housing demand. NYC might be the one exception but even there the surrounding suburbs have a lot of potential. We need high-density housing but we really don’t need buildings above 80 feet tall to achieve it except maybe in NYC.

The climate benefits of building height max out between 5-10 stories anyway.

Limiting buildings to tree canopy height cements the housing crisis. We need high density housing.

It's a bad situation to be in. Every where you look there's pain.

I think you misspoke, "purely for growing food and rearing livestock" includes both growing human food and livestock feed when I think you only meant growing livestock feed.

Tell your federal representatives to reintroduce the TREES Act. This bill directs the Department of Energy (DOE) to establish a grant program for states, local governments, Indian tribes, and other entities to facilitate tree planting projects that reduce residential energy consumption. Under the program, DOE must award grants to facilitate the planting of at least 300,000 trees annually in residential neighborhoods.

Reply to Endangered male northern quolls are giving up sleep in favour of having more sex – and it could be killing them, according to a study that investigated why male northern quolls usually mate themselves to death in one season while females can live and reproduce for up to four years. by MistWeaver80

Maybe they can sense their dwindling numbers and are trying to repopulate as quickly as possible. Sacrificing themselves for preservation of the group.

They make such a huge difference. I’m in Minneapolis and aside from the most urban areas, we have nice large trees everywhere except for the new developments.

I hate seeing new developments where they just completely destroy the landscape and then plant stupid little trees that only grow to 10-15’ high.

This reminds of “How’s the Night Life on Cissalda?” by Harlan Ellison. An alien race arrives on Earth and sexes people to death.

Reply to US Emissions of the World’s Most Potent Greenhouse Gas Are 56 Percent Higher Than EPA Estimates. Electric utilities are likely responsible for the nation’s higher than expected emissions of sulfur hexafluoride, a greenhouse gas 25,000 times worse for the climate than carbon dioxide. by Wagamaga

I don't know if the situation is getting better but, sf6 is used in every HV system as the gaseous dielectric medium. Wind turbines add to that more than ever.

Also, its lifetime in the atmosphere is 3200 years; even more than co2.

Yeah the whole point of a roof is to keep the elements away from the house. Adding tons of soils and vegetation and watering it everyday is just asking for trouble, specially if you cheaped out on the installation.

Eh, green roofs are usually realllllly heavy and require much bigger foundations. Better to limit building to tree-canopy height and get the vegetation benefits from overhang canopy.
