These researchers from Canterbury University have come up with an idea that they say can cheaply remove 3 million tonnes of CO₂ from the air each year. And it utilises existing infrastructure.

The TLDR is that geothermal water contains CO₂, and the stations here have systems that capture and dissolve that CO₂ into the water before it's reinjected. This CO₂ rich water is heavier than the surrounding water, so it sinks to the bottom.

The heat from geothermal wells is not replenished at the speed it's taken by the stations, so eventually the water coming out isn't hot enough and new wells need to be drilled.

The scientists are suggesting that instead of simply drilling a new wells, we burn biomass from forestry to heat the warm water up the last bit. The carbon in this fuel has been gathered by the trees, and if it was released into the atmosphere it would be carbon neutral. But if you use the station's existing CO₂ capture and dissolve systems, the carbon goes underground permanently. The operation becomes a carbon sink that also enables the use of geothermal energy that would otherwise be unusable.

They say, "in terms of buying ourselves out of an emissions liability, geothermal carbon removal is one of the cheapest options out there." They compare it with the cost of switching from a petrol to electric car - US$700 for each tonne of CO₂ saved. With the existing infrastructure, they say their plan would remove CO₂ at a cost of about US$55 a tonne.

Their papers and a bunch more evidence and info is linked in the article.

I want to finally get an icon up for !newzealand , but I want you to decide between these two.

The icon will show up as a circle in some places and a square in others. Both could have some small tweaks if they're chosen.

Vote on the comments. Best score at 10pm Thursday will be the icon.

EDIT: Well that was pretty clear. The kiwi it is. Thanks to @sortofblue@lemmy.nz for the suggestion.

The Hākaimangō-Matiatia​ marine reserve would cover a 2350ha area northwest of Waiheke Island, but it's been stalled after opposition from the Ngāti Pāoa Iwi Trust. However, the Ngāti Pāoa Trust Board supports the reserve. This is the fourth marine reserve to be delayed or cancelled recently after opposition from iwi groups.

"An international survey of almost 22,000 adults across 29 countries found British people had the third-most enthusiastic outlook towards refugees, just behind Spain and New Zealand."

Edit: Just found the actual report by Ipsos. We are #1, not #2. Fixed the title.

Edit 2: We're also the most likely to agree that refugees make a positive contribution to our country (70%). And here's the breakdown on the central question:

Based on feedback from this post, we're going to trial pushing for more politically controversial posts to go in !politics instead of !newzealand.

We're interested in seeing where users think the line is. Which of these recent posts do you think belong in !politics?

1. Frustration mounting as high school teacher strikes roll on - 1News
2. All Whites game abandoned after alleged racial abuse - RNZ
3. ‘Random’ group of Kiwis caught protesters who lit Parliament fires - 1News
4. Teacher struck off after refusing to use student’s pronouns - 1News
5. New additional ETS scheme floated in review of carbon market - RNZ
6. Migrant workers being exploited, Queenstown Citizens Advice Bureau says - RNZ
7. Operation Pakari: More arrests of people linked to Mongrel Mob, 85 charges laid - RNZ
8. Auckland surgeons must now consider ethnicity in prioritising patients for operations - NZ Herald
9. This RNZ story is probably more complicated than first thought - Stuff
10. Teacher struck off after refusing to use student’s pronouns - 1News

We're not able to move posts to another community at the moment, but we're thinking of locking posts that should be in !politics and asking the OP to cross-post them there. Do you think this is the best approach?

And it sounds like a Geiger counter when it's sniffing things out

The Create Post page says that it can accept videos in the html, but when I just tried to upload an mp4 I got this error:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Are we supposed to be able to upload videos here?

The biggest problem people seem to have with Lemmy at the moment is the lack of content.

If and when r/newzealand comes back online, it would be possible to set up a bot that copied new posts from there to lemmy.nz (and possibly from other NZ related subreddits). That would help get the content we need to get people to stay here.

There are downsides to this. Most content here would be from Reddit, rather than this community - at least for the time being. And there would be posts asking for advice, etc. that don't make much sense without OP here.

The second issue would be helped a lot by filtering out posts with Advice, Discussion, Meta or AMA flairs. We could also use the other r/newzealand flairs to repost to the appropriate communities here.

So what do people think? Is that something we want to do?

EDIT: What do people think of @Dave@lemmy.nz's idea of posting into its own community, so people could opt out in or out?

EDIT 2: It doesn't seem like this is popular. People seem happy for content to be copied over by hand, but not by a bot. To be clear, I'm not talking about bot-generated content, I'm talking about grabbing human-generated content with a bot. Some people seem to have got that confused. It would be doing a kind of manual federation of r/newzealand - especially if the content was kept within it's own community.

But it's kind of a relief. It would have been a lot of work to set it up. On the other hand, I'm not at all keen on going back to Reddit to look for stuff to manually copy over here either. I don't know if others are. I'm just worried that people will feel like they're missing out on so much here that they go back. If there was a Reddit cross-post community, people would have the option to get everything from here and stay off Reddit altogether.

If we loose enough members to a lack of content, the community will die. That would be a real pity.
