“Marginal improvements to agricultural soils around the world would store enough carbon to keep the world within 1.5C of global heating, new research suggests.
Farming techniques that improve long-term fertility and yields can also help to store more carbon in soils but are often ignored in favor of intensive techniques using large amounts of artificial fertilizer, much of it wasted, that can increase greenhouse gas emissions.
Using better farming techniques to store 1 percent more carbon in about half of the world’s agricultural soils would be enough to absorb about 31 gigatons of carbon dioxide a year, according to new data. That amount is not far off the 32 gigaton gap between current planned emissions reduction globally per year and the amount of carbon that must be cut by 2030 to stay within 1.5C.
The estimates were carried out by Jacqueline McGlade, the former chief scientist at the UN environment program and former executive director of the European Environment Agency. She found that storing more carbon in the top 30 centimeters of agricultural soils would be feasible in many regions where soils are currently degraded.
McGlade now leads a commercial organization that sells soil data to farmers. Downforce Technologies uses publicly available global data, satellite images, and lidar to assess in detail how much carbon is stored in soils, which can now be done down to the level of individual fields.
“Outside the farming sector, people do not understand how important soils are to the climate,” said McGlade. “Changing farming could make soils carbon negative, making them absorb carbon, and reducing the cost of farming.”
She said farmers could face a short-term cost while they changed their methods, away from the overuse of artificial fertilizer, but after a transition period of two to three years their yields would improve and their soils would be much healthier…
Arable farmers could sequester more carbon within their soils by changing their crop rotation, planting cover crops such as clover, or using direct drilling, which allows crops to be planted without the need for ploughing. Livestock farmers could improve their soils by growing more native grasses.
Hedgerows also help to sequester carbon in the soil, because they have large underground networks of mycorrhizal fungi and microbes that can extend meters into the field. Farmers have spent decades removing hedgerows to make intensive farming easier, but restoring them, and maintaining existing hedgerows, would improve biodiversity, reduce the erosion of topsoil, and help to stop harmful agricultural runoff, which is a key polluter of rivers.”

the crab day thing kind of proves staff must think we’re all fucking idiots
hi there. tumblr as a website is currently operating at a deficit because nobody wants to pay for ad free browsing. this is because basic quality-of-life features are either nonexistent or malfunctioning, our staff refuses to take the most trivial of anti-hate speech measures despite demonstrating the tools to do so against minority bloggers, and every form of content moderation is heavily and transparently weighted against the LGBT community. as the people in charge, we have decided that we’re going to ignore all of those factors and instead make an appeal to nostalgia to get you to buy dumb cosmetic bullshit for your dashboard while we threaten to turn the website into an even less functional twitter clone, much like how all the smartest shipwrights in the 1920s decided to model their new vessels after the RMS Titanic.

Anatomical Venus I
Wait please tell me more
I’d be happy to! So there’s been an interesting connection between pornography and anatomical diagrams for a very long time. My research was specifically on the Enlightenment in Europe, but you can find examples dating back to the Renaissance and the Middle Ages. There are a number of “pinups” that were made blending the erotic and the medical, with the subject wearing a coy, coquettish expression while literally baring everything to the viewer. When I say everything, it’s very similar to what you’ve done here: they hold up flaps of skin and show off their internal organs, bone structure, etc. There were even “political cartoons” lampooning this trend.
!!!! This is so cool, thank you so much for sharing! Super interesting to read. And very fun to see images from the past that are literally….the same concept, amazing

personally don’t think egg jokes are creepy as long as you’re not directing them at the subject, not being obsessive about it, etc.
especially right now, feelings on trans women are running hot, and tbh i’m more suspicious of people who are shocked and horrified at the possibility of someone being a trans woman than tgirls saying “haha just like me”.
“Oh you think men can’t be feminine? You think a man being interested in girl things means he’s a woman?” well in her personal experience it did, and she’s just doing that thing humans do where they project their experiences onto other people. Its pretty harmless, especially when said as a joke (with the understanding that its not necessarily true) and I don’t want to get on a girlie’s case about it.

thinking about what is and what isn’t allowed in frame with reference ecosystems in prairie restoration
Explanation from OP in the replies
restoration ecology tends to want to restore to a past state of an ecosystem, but magically that past state never involved people! Harvest, reciprocity, etc are all ignored because we pretend there’s such a thing as prairie without people. Turns out, that imagined prairie never existed, there were always people here and there should people involved in restored prairie too!

Goddamn management company can’t bare the idea of a single month without profit they’re booking viewings for our apartment before we’ve even packed our stuff well I hope you guys can keep a straight face showing a potential future tenant around our wall of furry art you fucks
They cancelled 9 minutes before the viewing. Pussies.
Love the concept of coincidentally making your living spaces untourable for shitty landlords.
Is this like the furry equivalent of shooting off a few guns now and then in order to keep the property values low?
My apartment is a cognitohazard to the well adjusted it’s like the ethical cousin of hostile architecture

I see his robot as an absolute win
OK - a very tangential takeoff: Engineering prof assigns students this question: Explain how to determine the height of a very tall building using a barometer.
Obviously meant to use change in barometric pressure with altitude. But one student submitted the following:
There are several ways of doing this
1. On a sunny day, stand the barometer up in the sun, measure the length of its shadow relative to its height, then measure the length of the building’s shadow and calculate its height from that.
2. Go into the stairwell and climb the stairs to the top, marking off the length of the barometer on the wall, giving you the height of the building in “barometer units”.
3. Go onto the roof of the building and drop the barometer off the top and time how long it takes to hit the ground, then calculate the height using the well known formula of 32 ft./sec./sec.
4. Go into the office of the building superintendent and say “If you tell me how tall this building is, I will give you this nice barometer”.
Newton….
This is basically any DnD party solving puzzles but with more success.
