Inspired by @BlossomLikeFlowers I've been working on a similar mini #greenhouse - what I have learnt is I will never be a carpenter and also working with perspex/acrylic is hard...
It's mainly wood from other projects and the perspex was from a table cover we've had in storage. It hinges at the top and has triangular pieces on the side. Still need to fix one of sides and also build a back but it's taking shape.
Still got a lot of seeds to sow but things are well under way. Very happy with all my little babies. #allotment #gardening #greenhouse #seedlings
Buying carbon credits to fight climate change? Here’s what to know
#CarbonCredits sold on the voluntary market are under scrutiny for not offsetting #Greenhouse#Gas emissions as claimed.
One investigation concluded that over 90 percent of carbon credits issued for #rainforest protection by the largest carbon credit certification body “had no benefit to the climate.” Two reports published in 2023 found that credits for forest-based projects in North America, South America, Africa and Asia may in fact #increase net #emissions.

Lufa Farms has the right idea - building rooftop greenhouses for fresh veggies above hyperstores/supercenters. They currently serve #Quebec and #Ottawa
https://montreal.lufa.com/en/about
(rooftop solar panels: also a good idea)
Over the past few weeks, I have been working on a compact greenhouse on wheels. It’s almost entirely created from upcycled materials. Our neighbors generously gifted us with some plexiglass he had laying around.
As a result we are able to move the greenhouse depending of the sun‘s position. We have also started some growing some new seedlings, including corn, kidney beans, kohlrabi and radishes.
Winter damaged #Schwiemu's greenhouse a little more. It's old and the fabric weakened from UV radiation, but every year we patch it up for "just one more season" 
Last time I've sewn it with zip ties, this time no zip ties around, so I used some aluminium wire which itself was pulled out of old cables.
Hope it lasts one more season!
Right, some initial notes on these #RP2350 Melopero Perpetuo #LoRa boards: https://yvan.seth.id.au/melopero-perpetuo-first-notes.html
Long story short: they work... I can make LEDs flash, that's the key thing... right? 
Can also read the internal temperature sensor and check battery status.
A few "bugs" in the examples and a slightly faulty board.
So far, so good... Next job is to get one of them transmitting the temp and battery status to the other. Will need to think about how to "package" that data for reliable tx/rx, probably need some redundancy, etc, maybe a buffer window of data. Then I need to dig out some of my various sensors and decide what to hook up to the "remote" to send to the local. The local will probably then relay data to a connected computer via the serial console I guess.
Project #Polytunnel Telemetry is GO! Well, if I can get a signal that far, otherwise this becomes project #Greenhouse Telemetry... the greenhouse is about 30 metres away, the polytunnel is a kilometre.
#Cattle husbandry emits #greenhouse gas.
For example:
* South America and the Indian subcontinent breed most bovines who emit most methane.
* China and the Middle East produce too much livestock methane in regard to their bovine headcounts.

The workshop I built for my wife after the first lockdown, mainly to stop her from taking over mine(!)
I’d always been intrigued by the idea of stitching a shed and greenhouse together, so knocked this up. The idea is that the greenhouse captures solar heat in the winter to help heat the workshop - it seems to work, and the shed is very heavily insulated with polystyrene collected off the local beach over a summer and put through a garden shredder.
With a small radiator, the temperature gets up to about 22C very quickly, even with outside temperatures around zero. When they’re about 8-10C and upwards, no heating required.
Built mainly out of free stuff (greenhouse, roof tiles, much of the frame, insulation, copper ridge, windows, door).
Please ignore the oil tank. We inherited it and can’t afford to change systems.

When nipping out to go to the post office I noticed it was fairly still, so I grabbed the shitty little drone and managed to take some iffy #allotment photos without losing it (it tried to bugger off elsewhere a couple of times, as usual, bastard thing.)
For the uninitiated, our plots are the one with the biggest #polytunnel in the middle and the one next to it with the glassless #greenhouse frame adjacent to one end of the polytunnel... and lots of junk (current main work-in-progress).
No rain here so far today, but cold and drab outside, uninspiring weather - apparently rain or even snow tonight, I'd like a bit of snow... snow is fun.
For comparison here is where we were at in late October: https://toot.ale.gd/@yvan/113375010347200497
Pittsburgh originally had two public conservatories,
both established by Henry Phipps, Jr.,
childhood friend of Andrew Carnegie
and second largest shareholder in Carnegie Steel.
In 1886, Phipps donated $25,000 to establish a glasshouse in his hometown of #Allegheny #City
—today’s North Side.
This first Phipps Conservatory became a very popular destination.
It has undergone many iterations,
and we know the site today as the National Aviary.
The 9-room Phipps Conservatory in Oakland’s #Schenley #Park opened in December 1893 as another gift from Henry Phipps, Jr.
—this time to the City of Pittsburgh.
It showcased many plants that had been on display at the 1893 World's Columbian Exposition in Chicago.
THE FRICK GREENHOUSE
The #Frick #Greenhouse was built in 1897
when Mr. Frick hired the Pittsburgh architectural firm of Alden & Harlow to add to his estate.
It wasn’t the first such structure at Clayton, but this new one was meant to be a showpiece.
According to the papers “no expense was spared” and it was described as " . . . one of the most modern public or private ones in the state of Pennsylvania, and possibly in the United States.”
Alden & Harlow worked with Lord & Burnham, an American company
renowned for its conservatory design.
Among other efforts, The New York state-based Lord & Burnham created the Schenley Phipps buildings,
worked on the Golden Gate Conservatory,
and designed the conservatory at The New York Botanical Garden.
Glass houses like the Frick building were often built of durable cypress or white pine, with structural elements of iron or steel.

I thought of doing this in 2016, but stopped talking about it when every reaction was negatively triggered by my race.

@AlJazeera host #KevinHirten interviews Plant Based Treaty's #JuanPabloCasadiego and #AnitaKrajnc: "A third of #greenhouse gas #emissions come from the #food industry, largely from #meat, #dairy and #eggs. The international #PlantBasedTreaty aims to combat this by advocating for a #vegan diet as a key solution to #climatechange. Backed by cities, universities, Nobel laureates and thousands of individuals, it seeks to align global efforts with the #Paris #Agreement."
Five years of no flying 
5 years ago, I realised that my #academic travels were emitting way too much #greenhouse #gas #GHG (up to 20 t #CO2 / yr) and hence that my #professional activity was not #sustainable. I thus decided to completely ban air #travel (#plane) and travel mainly by #train within #Europe.
5 years later (i.e. now), my professional travels' #carbonfootprint dropped by **a factor 50**, without impacting my #publication records (compared to 2017 - 2019).
I wrote a post for the #blog of @a4e about my experience. Check it out: https://astronomersforplanet.earth/five-years-of-no-flying/

Thermal mass and sunken greenhouses for extending the growing season in freezing climate.
Found the missing greenhouse. In two large crates in the big barn.
Some assembly required.
I guess the frame was wood and rotted away and they saved the glass panels.
Might do something with that one day. Latvian dude's thermal mass greenhouse design was sparking some ideas.
Will need a lot of window cleaner! :)
COP29: Climate leaders were worried Trump would derail talks. They didn’t know their host would be the wrecking ball | CNN
To be honest, I am sick of this charade. #Climate activists have not been able to unite the #politicians with the #scientists. The population in countries dependent on fossil fuel energy isn't enthusiastic.
1. Deforestation is targeted but progress is slow. Growing the forests can help local economies. It takes a consolidated effort with economists and political leaders. This is probably the biggest component but one of the least talked about.
2. Most of the activities involving EVs around the world have produced very little net impact due to battery technology being the rogue element. It is simply used by the Left in US as a political tool. The positive outcome from the effort of course has been a slow advance in the battery technology innovation.
3. Agricultural innovations are behind. Soil engineering can pay a big part but companies like #Monsanto won't like that. #Pesticide and #fertilizer companies using chemicals continue to destroy natural soil around the world and produce #greenhouse gases faster than ever. Banning beef won't go anywhere. People like to eat good food. But there are ways to reduce the impact of food production.
