When those of us who work on CO₂ removal (CDR) meet, it’s apparent that no one wants to do this and no one thinks it’s easy.

It’s far easier and cheaper to stop emitting CO₂.

The fact that some of the smartest people I know decide to work on CDR signals our desperation.

@davidho

So you followed a #vegan lifestyle for many years I guess?

https://www.nature.com/articles/s43016-023-00795-w

If yes, when you talk about #climatechange as a problem, can you please promote #veganism as an important thing to do and in your bio? Thanks.

Vegans, vegetarians, fish-eaters and meat-eaters in the UK show discrepant environmental impacts - Nature Food

Modelled estimates of the environmental impact of dietary choices often fail to reflect true dietary practice. This study links a dietary dataset from 55,000 UK consumers with food-level data on GHG emissions, land use, water use, eutrophication and biodiversity to compare the environmental burden of different levels of meat consumption.

CC @anders because you boosted it and you have a profile cover image related to climate change. Thank you.
@alexl for almost 40 years

@davidho

So you were so desperate to specialize in CO₂ removal but you don't bother to promote the most effective thing everyone can do to reduce emissions in the first place?

Can I say that it doesn't seem like an efficient strategy to me? Today you can spread solutions like this with an exponential speed on the Web.

@alexl I don’t specialize in CDR. I specialize in understanding the earth system and the carbon cycle, especially in the exchange of CO₂ between the atmosphere and the ocean.

Read my work before making uninformed statements.

Start here on what I think about CDR: https://rdcu.be/dbFbB

@davidho

It was you literally saying in your post:

"When those of us who work on CO₂ removal (CDR)"

Your sloppy reaction suggests to me that you don't follow a vegan lifestyle and for sure you don't bother to promote it. But you still like to complain about CO₂ emissions. Maybe people need to know a plant-based diet is very effective to reduce those?

If climate scientists aren't consistent with their claims, some people might think you're scaremongering for more funding for your research.

@alexl Your contributions haranguing random people on the internet will never be forgotten. If humanly survives, we will truly have you to thank!

@ThisAccountKillsFascists

What interests me are the sentient beings of other species and if this story of climate change can reduce those concentration camps that are farms, I am happy to call hypocrites those climate scientists who do not follow a plant-based diet.

@alexl @davidho I'm glad you two are talking about this face to face, without emitting co2 with devices and apps and servers and all that stuff.

Cmon Alex, this issue has many layers, it's not up to somebody to decide that one specific layer comes before all the others.

Being vegan is a very healthy habit for the planet, and promoting it is the right thing to do. But being this aggressive send people away from a thread, and that's not ideal.

@pblu @davidho

You clearly haven't read the article, otherwise you would know that a plant-based diet is orders of magnitude more effective than anything else.

And you're are finding excuses to not reply on the matter.

I don't care about communication, I'm here to expose the hypocrites.

@pblu

Just out of curiosity, is calling people that are skeptical on AGW "deniers", making fun of them, portraying them as the most ignorant ones, hating them, threatening them and asking for laws that punish them not sending them away? Is that ideal instead?

@alexl I don't see where I used those words.

@pblu

I have tons of posts like that in my timeline right now and no replies like yours on being aggressive. They are waiting for you.

@alexl @davidho Are you seriously getting aggro over a vegan's omission of veganism from their bio
@alexl @davidho Or is this just a weird bankshot way of saying you want the oceans to boil?

@ostrich

Read my other replies. In short: I don't care about climate change, I just want to take advantage of people worried about it to promote a plant-based diet.

@ostrich

In case it is still not clear: the few people following me don't care if I am a vegan, it's a personal choice.

The thousands people following a "climate scientist" that talks a lot about how important is to reduce emissions would be way more incline to adopt a plant-based diet.

@alexl
> I don't care about climate change

opinion discarded

@ostrich

Why should I? The people claiming there is a #climatecrisis don't even bother to go #vegan and promote a #plantbased diet.

@alexl @ostrich

/You/ may not care about the #climatecrisis but its effects will destroy your health, finances and finally your life just as anybody else - regardless of your diet.

PS: Nominated your toot as one of the most stupid ones of the day.

@proscience

People like you don't even bother to go vegan and promote a plant-based diet. Why should I worry if not even you are taking the "climate crisis" seriously?

@alexl @ostrich oh that's fucking awesome, don't stop posting, don't log off
@alexl @davidho

being vegan doesn't reduce emissions.

@alexl @davidho

🍑💨

All the carbon emissions you save over a lifetime of veganism will be farted out of a private jet by a billionaire running errands over a weekend.

All the carbon emissions you save over a lifetime of veganism will be erased by a mundane routine military jet engine test.

The most effective thing you can for the climate do is eradicate billionaires and abolish the military.

@municipaladhesives

No, it's the opposite, and by many orders of magnitude

@davidho @alexl if a private citizen wants to donate to carbon sequestration, where is the most effective way to do it?

@bsweber

He just said it is a desperate attempt and it is better to reduce emissions on the first place... the best thing you can do is adopting a plant-based diet and make other people do the same.

@alexl @davidho

Don't let perfect be the enemy of good. Step 1 of avoiding driving off a cliff is deciding to take action. Step 2 is taking your foot off the accelerator.

Converting the whole world to vegan overnight isn't going to happen. What could happen, is asking people to replace some of their beef consumption with anything else, as it is about 3 times as bad as chicken, and IIRC, twice or maybe 50% more harmful than pork.

@chidi_anagonye @davidho

No one is saying the world should turn vegan overnight.

What interests me are the sentient beings of other species and if this story of climate change can reduce those concentration camps that are farms, I will make sure so called climate scientists are the first to follow a plant-based diet, to save at least some more lives.

Every single life counts, this guy has 7K followers and each of them who is not following a plant based diet causes many deaths every year.

@alexl @davidho

I think you would be more effective by keeping your message short and shedding some light on how poorly animals are treated. Link to some research about how these creatures aren't just brainless meat.

@chidi_anagonye @davidho

I have been an activist for many years and I know exactly the limit of that approach. Let me say that using science where only empathy is needed is one of the peaks of the dystopian-level scientism of our times.

Today we are flooded by alarms on climate change, many people are worried about it but vegans are still 3% at best in Western countries.

I will take full advantage of these circumstances to promote a plant-based diet.

@alexl @davidho

One more thing. Any reduction does something incredibly valuable. It buys time for people like David to develop GHG sequestering ideas. It buys time for governments to pass legislation. It buys time for more efficient tech to come on the market. It buys time to convince others to take action.

@alexl On behalf of Exxon, Shell, BP and others: thank you, Alex, for pointing out this hypocrisy! It's a huge shame @davidho doesn't say anything about personal responsibility, and doesn't promote individual methods of combating this issue, shifting it onto someone else.

@brawaru

The livestock industry pollutes more than the entire transport sector. It's 10 000 000 000 individuals killed every year that need to be fed for years.

The oil industry exists because people consume energy for everything.

There is no way to produce energy without emissions and there probably isn't enough rare-earth elements for batteries.

So sorry, going #vegan is the only thing you can do and it is the most effective one, way more than anything else.

@alexl
> The oil industry exists because people consume energy for everything. There is no way to produce energy without emissions.

You are very rational in your thinking, thank you a lot for saying this out loud. People definitely should be embracing vegan lifestyle and other ways of personal responsibility, like saving water, not leaving food waste, and otherwise carefully monitoring their carbon footprint. It's such a shame that some extremist personalities can't simply accept these facts.

@brawaru

Anything else is almost useless when it comes to emissions, going vegan and making other people go vegan is way more effective, it saves other animals from a life of torture and it helps against desertifications and pollution.

So, sorry, I won't tollerate any dilution of this concept.
