Climate crisis

This is the same pm who doesn’t like living streets because they inconvenience motorists and you ‘should be able to drive where and when you like’. Go back to the 80s you daft tory

(Catastrophisation trigger warning)

Depends on how you see the scenario playing out. There’s so many variables and unknowns that at best you’d be guesstimating.

If it all goes sideways suddenly and food supplies collapse, a single prepared individual likely won’t make it for long. It’ll take community efforts to gather, protect and distribute food.

If it’s a slow slide instead of a crash, then a stockpile might help keep spirits up and support your personal intake during scarcity. If things get bad there is the chance that food will be confiscated and rationed, so having a stockpile won’t help you unless you keep it all well hidden.

No harm in keeping your favourite exotic preserved foods in store though.

Been playing more with the Governments visualisiation of what we need to do to meet net zero

It seems bias towards carbon capture (444444424444444) over other solutions. Renewables seem to have much less influence that I imagined (444444444212244),

That can't be right? Carbon capture is still mainly theoretical no?

Haven't they just announced new carbon capture projects?

We currently produce 30 billion tonnes of CO2 a year. (And have been at that level for years!)
In order to capture enough carbon to reduce the amount in the atmosphere to safe levels we need to remove all that CO2 and a significant proportion or what’s been pumped in before. Let’s say 25 years worth, or 750 billion tonnes. Factor in what we’re going to produce in the next 25 years and that could be the same again, so a potential total of 1500 billion tonnes.
The biggest CO2 capture facility currently in existence captures about 4,000 tonnes per year. So industrial scale CO2 capture is a pipe dream. We won’t have any facility running at the appropriate scale for decades, if ever, because we can’t hide that much carbon easily.

Pump it into space init

as a rule of thumb is Elon is excited and bigging anything up, ignore it

Heads over to the Procycling thread. Oh the ironing.

Will our planned cuts in emissions be wiped out by the growing Co2 from wildfires? How do the numbers compare? (1100 wildfires currently in Canada).

This is one of the downfalls of “nature based” projects for carbon sequestration. As the climate changes a lot of areas become drier and or fire prone, so wetlands dry up releasing carbon dioxide as they do so, and woodlands and forests catch fire, with the same but more obvious results.
There is yet no sure way of locking up carbon, the only real solution appears to be a rapid transition away from burning fossil fuels, and of course we’re simply not going to be able to do that.
Even if we stopped right now the legacy of all the carbon already released will affect us for many years.
Despite all the climate related disasters we’re currently witnessing that appear to be attributed to climate change, we aren’t at 1.5 degrees above pre industrial levels. We’re heading for 3 degrees according to the consensus among the scientific community looking at such things.

Will our planned cuts in emissions be wiped out by the growing Co2 from wildfires?

A bit of googling reveals that total CO2 from wildfires was about 2 gigatons in 2021. But when natural regrowth occurs in the burnt areas, 80% is recovered.

https://www.preventionweb.net/news/wildfires-2021-emitted-record-breaking-amount-carbon-dioxide

2 gigatons is roughly 2.5 times the annual total from Germany.

This is the assumption behind most climate modeling, if you look at the IPCC models, the majority rely on massive amounts of CCS in the future

Fossil fuel companies love it though as the view it as a license to keep pumping oil

Yes was part of the announcement of new oil licences and Biden just announced funding for two schemes and one of the companies involved was promptly bought by occidental oil

As far as I know this is the only successful commercial scale Carbon Capture project,
and,
it is not attempting to remove CO2 from combustion flue gases;

https://sequestration.mit.edu/tools/projects/sleipner.html

Over what period does the recovery take? It doesn’t say. And if the conditions for regrowth aren’t optimal ( e.g. continuing drought) that figure could be a lot less.

There is yet no sure way of locking up carbon

Combine it with hydrogen, liquify it and store it thousands of meters underground. But maybe add some sort of warning or stop sign this time around.

Ffs why am I bothering to pay in to my pension

Dead link?

Odd still works for me, is an FT article called Lex in depth: how investors are underpricing climate risks

Social scientist explores the models. Rather than buy them a drink in a disco, fits the uncertainty to his thesis.

It is easier to call oneself a materialist than it is to be one, because self-declared materialism has an unfortunate tendency to turn into its opposite.

six out of nine ‘planetary boundaries’ had been broken because of human caused pollution and destruction of the natural world

The denialists should be the first human victims not the last, ffs

V interesting if accurate🧐
