[flagged] Greta Thunberg (wikipedia.org)

I think Greta, along with David Attenborough (and the programmes he voices) and Extinction Rebellion have really put climate change back in the news in the UK.

Extinction Rebellion ran some of the most effective (or disruptive) protests seen in recent years, all without getting violent. Building a skatepark on a London bridge, dropping a yacht at a busy junction, gluing protesters to stuff. All new, all guaranteed to annoy the climate change denying right.

Greta's speech to the EU parliament really impressed me. Seeing the deniers personal attacks on her made me sure she is making a difference.


Does this mean you favor the end of air travel and high speed rail everywhere by 2025 plus a general strike? That's what Greta is asking for - a complete cessation of carbon emission by that date. Please indicate how you think this will pan out.


This is the kind of logic, that always kills me: "There is no climate catastrophe ahead, because avoiding it would mean unthinkable restrictions".


It is almost as bad as the logic that since I think Greta is doing a __good_thing__, I must therefore wholeheartedly agree with every point she ever makes.


Exactly!

;-)


Poster child for the child abuse the climate alarmists have wrought upon a generation. Are the lasting psychological effects of instilling so much fear in so many children really worth it? We’re not all going to die on account of climate change—nor will our grandchildren. Endless war in the Middle East and child labor in rare-earth metal mines in Africa are what children should be speaking to the UN about.


You probably know how feedback (both positive and negative) work in systems. If not, it is the same process that makes a microphone scream if you are too close to the speaker. Often the area between no feedback and full on feedback is really tiny.

Climate is similar – with the tipping point according to current models around +1.5°C average temperature. That means if we manag to limit it to <1.5°C we won't enter a region where climate warming accelerates itself to a degree that makes it unstoppable.

And there is literally no debate about these mechanisms – there is a >97% consensus on this.

Of course we can do the silly thing and try out what happens, ruin our own existential basis, get the predicted migrant waves, conflicts, economic damages etc. Or we could do what a civilized society would do and act accordingly.


> if we manag to limit it to <1.5°C we won't enter a region where climate warming accelerates itself to a degree that makes it unstoppable.

Grateful if you could point to a source that shows a >97% consensus on that statement. Genuinely interested, not trolling. Thanks.


The amount of "feedback" involved in climate systems is the very thing that makes them incredibly hard to predict and make solid claims about. The claim that there is "consensus" that a runaway process will happen if warming hits 1.5C, and that no other, countering feedbacks exist that could mitigate this effect, is kinda preposterous given the inherent complexity of what we're dealing with. Even something as simple as cloud cover, and how it would respond to a "warmer" planet, is stuff that there's a lot of uncertainty about.


I think our collective effort to advance our climate knowledge by testing these hypotheses, despite the existential risks, shows an admirable commitment to science.


Our grandchildren are probably not going to die of climate catastrophe. However, that “probably” is sufficiently weak to justify a huge urgent response.

An asteroid with a 3% chance of wiping out hundreds of millions of people in 60 years would motivate us to deflect it. The long tail of climate outcomes is a worse threat than that hypothetical, and we’re doing precious little to prevent it.


I actually agree about the scaremongering coming out of the Thunberg camp, but come on, it's not like she's doing this personally. She's a figurehead for a relatively niche movement that's trying to make it big, and she can surely handle this role. It's not any harder than the things that she did engage with personally in a decision-making role - namely, the initial school protests (that she was entirely right about, btw - the Thunberg/post-millennial generation is entirely disenfranchised wrt. lots of crucial issues not just climate, and they should be very visibly upset about this!)


It's sad that only MPs are allowed to speak in the Swedish parliament. There are quite a few politicians who don't take her seriously here, in her own native country.


I mean, she's great and I'm a fan, but I don't get why this is here?


Feel like this section of the guidelines have to be added above the commenting box soon.

TLDR: it's here because people found it interesting and upvoted it.


Yeah I don’t think I’m unique amongst “hackers” in that I have many disparate interests, and generally enjoy reading about something new, regardless of what the topic is


Just to clarify: you hadn't heard of Greta Thunberg up until now?


Virtue signalling, mostly.
