Climate change is driving up peak summer temperatures across the country. Las Vegas broke temperature records last summer. Now, the region is fighting the heat with a simple solution: more trees. via @knpr.org

npr.orgFaced with rising temps, Las Vegas is embracing a simple climate solution: More treesClimate change is driving more dangerous summer heat across the U.S. Las Vegas, which reached 120 degrees last summer, is planting thousands of trees to help cool its hottest neighborhoods.

1: Las Vegas has enough water and returns something like 90-95% of what's used back to Mead. 2: Adding trees reduces ground evaporation but increases humidity, which leads to cooler air and more rain. 3: The reason there is a city here is that it's an oasis with springs. 4: We don't have lawns

Mead is currently at 1,055 Feet MSL- 174' below "full pool" and even with where it was this time in '23 ('24 = 1064 & '22 = 1044). This could be caused by several factors: users upstream taking more, Powell not releasing as much, less snowpack, and less local rain, but it's not an emergency. Yet

That's not a bad idea, since it's naturally 40-50 degrees F underground year round. But another thought, maybe just don't live there, in an ecosystem that simply can't support these population & development, instead of doing yet more desert development to hack around that basic flawed premise?

Trees have always been a big part of the answer. Plant rows of them along the streets, plant parks in the cities. Most of all, plant forests where old industry stripped the land. Air under a canopy is much cooler, and that spreads to the surrounding area.

The slight problem with trees is they take several years after planting before they are able to do the job that you are referencing. Sea grass , which is regularly destroyed by marine traffic is even more efficient.

Tree planting won't work unless carbon emissions are actually curbed. Because at a certain higher temperature, trees will breathe out more CO2 than they use to photosynthesise. 'Offsetting' is a false solution, cutting emissions will work much better

Had a local meeting with some city politicians and planners in Philly about a decade ago. When asked what would benefit us most We mentioned more trees. They ignored us and now a local park and playground is gone replaced with the ugliest gray boxy apartments you’ve ever seen that no one is renting

Great idea, proven to work. The criminal wants to chop down trees for lumber no one wants. Will add to climate change, with the roll back on climate initiatives, regulations. A lot of lrg corps want the rollback but if Americans die who'll buy their product? Makes little sense IMO.

To those who ask where the water is comming from. 🌱 A 2019 PNAS study shows that large-scale “desert tree planting” trigger wind convergence, boost cloud formation, and increase regional rainfall—all while sequestering carbon and cooling the land  www.pnas.org/doi/full/10....

Yes—at first. Just like deforestation slowly dried out regions over decades, restoring rainfall through replanting takes time. But long-term studies show tree planting can cool the land, boost moisture, and even increase rain. It’s a slow fix—but it works.

Great, but the trees have to get established and put on some size before that happens. So asking where the water will come from for the first several years, at least, is a valid question. The article you linked suggests using wastewater. A great idea! I wonder if they're planning for that.

Waste water is one way but we built our own rainwater system at home. Instead of letting rain water drain away, it runs off the roof, through a filter, and into storage barrels. It was super easy and cheap—cost less than $50 to set up—and now we have clean water ready when it’s needed most.

Progress always requires investment. Yes, young trees need water at first—but that demand can be drastically reduced with simple solutions like watering bags, which minimize evaporation and deliver moisture directly to the roots. Within a few years however they will be a net positive

I def wouldn't discourage it, hope it works. It's just that, having lived in CO for a couple of decades I know water is a bigger looming crises than most people are aware of. Too bad more programs like this weren't started much earlier.

Great idea but don't these trees need water which that entire region has had issues with in the last 30 years? Eventually the trees should support a more diverse and cooler ecosystem but at the cost of a significant amount of water this area is already lacking.

DUH. Here’s a novel idea, let’s just put the environment back as close as possible back to the way it was, you know, with trees and animals and bugs and stuff, just for a little while, just to see what happens. 🙄

If you read up on the lengths to attain efficiency the city, the businesses and the residents have gone to you might find it interesting. They have a surplus of reclaimed water which is on par with pond water. You wouldn't drink it without heavy processing but theyve put it to good use. They have->

restored wetlands for example. The plants, the microbes, and the natural filtering through porous cleans it and it ends up in an aquifer. Theyve had incentives to rip out lawns and use natural region appropriate shrubs and trees. They've also banned the installation of new residential pools etc.

Id argue it would be better to have our cities in deserts (with efforts to reclaim water, avoid waste etc) which are fed by rivers from verdant areas. instead of colonial practice of leveling forests and building right in the middle of the various resources that a city uses (and ends up exhausting)

More trees . . . but native trees. Easterners brought their water-loving plants westward--plants hungry for water. Overbuilding everywhere means there are fewer trees to provide shade, hold water, and be homes for animals. www.fs.usda.gov/learn/trees

I’ve been shouting this for years. What good is a palm tree? No shade, needs lots of water, and if a cat goes up, you need a 50 foot ladder to get them down. Scorpions love them, swimming pool hate them, and they’re expensive to trim every year. Give us Mesquites, PaloVerdes, and Aleppo Pines! 🌳

Better late than never, I guess? Bought my house 14 years ago in a much lower heat clime, and even then both my & my city were aware of "heat deserts," & I consciously bought in a mature forested neighborhood. Welcome to pre-2011 ideas, Las Vegas? But 2k trees/yr for a city that size is still weak.

No its not and it would be wise to stop misinforming people, or more accurately, keeping people scared on this non-existent subject bsky.app/profile/robi...

On #GrandSolarMinimum as described by #ProfessorValentinaZharkova, unknown to me, predicted a drop in #SolarCycle25, I also expected this #Volcanoes have reduced in their explosivity and now #GlobalTemperatures are dropping .. which tends to happen .. www.youtube.com/live/yO-nGu4...

That is not how it works Wow .. assertions in science, when did it start working like that? Sadly, for you anyway, it does not work like that but I can prove it if you so wish You also need the people and all scientists .. and you don't 😘

"oil lobbyist filling their pockets and your head" First part of your statement is pure made up bullshit from you, political at its core As for the rest? More made up bullshit to help you to cope I'm a multi-disciplined scientist that started much that others now widely state Stay out of science

I live here. They tear out our trees saying trees use too much water. Huge established trees we already have aren't allowed to be watered properly. Drip irrigation. They think 30ft pines can survive on 1 day a week drip irrigation. Then they decide to plant trees. But we still can't water. 🤷🏼‍♀️🖕🏼

Nevada really doesn’t have a decent native tree for the low desert. Even the alpine regions don’t have tall shade trees. The only species that I’m aware of that did well in both the low and high desert are cottonwoods, but Vegas and Clark county banned them because of their excessive pollen.

Las Vegas is the land of glitz, neon and fake. I don't think the native species should factor in all that much. We need shade. The community built in the 70's where I spend most of my time has ginormous pine trees. It's beautifully shady.
