Reply to comment by Various_Oil_5674 in 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 why it couldn’t be controlled better than it currently is. And I suppose that’s a pun.

Reply to 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

Places used to be like this. Why do you think you see so many “Oak st” and “Cedar Ln?” Funny how science and innovation can lead right back where we started

In general I agree but on a large scale, the areas that need the most shade also have the least amount of water.

Trees consume an incredible amount of water and that's a big deal in these places where the large shade trees don't grow naturally.

You are correct, I meant to say growing food for livestock and rearing livestock. Basically, 80% of land is to make meat and dairy and it only produces 20% of our food. The other 20% of our land use is for plants, and that produces 80% of our food.

All other human land use is about 1% of habitable land - a rounding error compared to farming

I hate going up on to my roof too. So many things could go wrong with a setup like that. Screw that noise. I want a low maintenance roof.

That's an asinine take. 40% of water use in California is agricultural and only 10% is urban (both indoor and outdoor). The other half of water use is environmental.

Water rights and water use incentives in agriculture are awful.

Just wait until you read about "super-Earths" that aren't Earth-like at all.

>"New data shows that TOI-1075 b is one of the most massive super-Earths discovered so far," NASA officials wrote referring to the planet that orbits it's host star so closely that a year lasts 14.5 hours and temperatures reach 1,050C°.

We should do all of these things. We need air conditioned spaces and renewable energy, but if we can reduce the urban heat island effect by increasing vegetation in general (and canopy in particular), then we won't need as much energy to cool those indoor spaces.

Tbf if the roads are narrower, drivers drive slower Plus speed limit is often at 30km/h in the city means car crashes are essentially non lethal

We really should't get too hand up on this. Street trees apply almost anywhere. And green roofs are fine but just the trees outside to cover the asphalt is already a massive improvement. Trees and some green roofs where possible is totally doable and a massive improvement. Looking for a perfect solution is a great way to do nothing

Of course. But you could immediately halt all exurban development and also provide plenty housing to ease the housing shortage if we just upzone inner-ring suburbs to medium-sized multifamily buildings.

Farming in general in California uses a lot of water, which is bad because there are also a lot of people in California. If Cali was just farmers it would t be a problem, but it is trying to balance the water needs of everyone that makes it an issue.
