Latest poll on Sky news:
55% of people would not reduce the amount they fly to help climate change
Does not surprise me. In my admittedly anecdotal experience this is particularly prevalent in the under 40s and under 30s even more so. They've grown up with regular weekend city breaks etc in foreign countries and have a real blind spot there. More than a few have life goals like visit every country in the world. That's clearly not sustainable for even 1% of the world population to achieve. Social media, bucket lists & YOLO as a philosophy has a lot to answer for. Add in long working hours, relative cheapness of flights and its easy to understand the appeal of a quick trip away somewhere. One 20 something I met recently had done 50 flights in a year and while being very informed about climate change and the impact of his own travel simply laughed and brushed over it saying he'd have to do something about offsetting it when he had more money one day. I did my first flight to another country in about a decade earlier this year and found the break such an enriching experience I was immediately mentally planning another on my return. I could see how it could become semi-addictive. My next holiday trip abroad will be via train again though and probably next year.

Going through the carbon footprint calculator cb25 linked to... www.carbonfootprint.com/calculator.aspxA single return flight to the Caribbean is about the same amount of CO2 as our 200m2 17th century house's electricity and bulk LPG consumption for the year. Unfortunately, I think it all went a bit pear-shaped later on. Apparently, our food consumption is about the same CO2 as both of those put together... <scratches head> Are you sure it was a mistake?

Airbus : "The Future Is Electric" www.airbus.com/newsroom/news/en/2018/07/the-future-is-electric.htmlSee that the demonstrator aircraft uses a conventional engine to get off the tarmac and electric engines to hoof it along in flight. Ultimately, the conventional engine will be hydrogen powered. If the climate system is going to be restored to stability, it is the development of hydrogen produced from electricity that is going to be much of the answer. Hydrogen can be produced as an alternative to battery storage of pumping water uphill. |

No, the other way around. The conventional engines are for primary use. The electric motors are only to boost power for take-off and landing. Oh, and it's not having its first flight until next year. And it's tiny - it's a converted BAe 146, the smallest four-engine jet they could find. Something the size of an A320 would require 10x the power.

Can someone please tell me how you get round the planet in a reasonable time without Flying or even more polluting ships ?
How many trees do I need to plant to cover a lifetime of meat eating.?
Doesn’t matter saved more than my lifetime C02 footprint. Didn’t have children 👶

Well, very green people have been known to take the train to Australia, filling in the gaps by boat. Really, I know it sounds crazy but they certainly are committed. My view is that short haul aircraft will move to bio fuel and battery (combo, see above), while ships will move to biofuel and rotating sail things. I also see that there will be trade barriers between countries who de-carbonise and those that don't. Much of this will be outside my life time.
I don't think that there should be a way you can "offset" your carbon behaviour. I think it is more and more about thinking how to de-carbon.
Doing the non-kid thing doesn't really count, you will still need the sitting in the care home thing. ;-)

Re: travel - I make more use of video conferencing, phone etc nowadays. Locally, most of my transportation is by bike.

Although a friend of ours has just returned from travelling around the world by car. UK -> China -> Alaska -> Patagonia -> UK. A small, old 600cc car. For two years. With a small child in the back seat. Yes, now there's a whole 'nuther environmental can of worms...

<<snip>> And it's tiny - it's a converted BAe 146, the smallest four-engine jet they could find. Something the size of an A320 would require 10x the power.
I spotted that. I also noted the commentary in the article thus:
"Airbus will involve BAE Systems Regional Aircraft in the design of the modification to leverage their unequalled aircraft knowledge and to work together with the other partners to approve the modification and release the aircraft for flight under their Design Organisation Approval."
First part: really ? Scratches head. Like that's why BAE have to all intents and purposes exited the commercial aircraft market, and were hawking their Regional Aircraft business around the bazaars for years, but have failed to find a buyer.
Oh look: that's a 146 they are using as a trial vehicle. That means it was a no-brainer to involve BAE as they will be the designated Design Authority as the OEM. So they need BAE to get it certified for flight. Ah, so Unequalled aircraft knowledge means specifically knowledge of the 146. Now I get it.

Perhaps humans (and animals) will need to stop breathing out CO2 then if we can't offset it by plants using it and pumping out O2. 
I think the non-kid thing really does count as CO2 emissions are related to population size, not linearly I'm sure, but population increase causes CO2 increase. From one of my previous posts:
One 2017 study co-authored by Lund University’s Nicholas ( here) states "From analyzing 148 scenarios of the climate impact of individual behaviours in ten individual countries ... we have identified a dozen actions, including four recommended actions that are of substantial magnitude throughout the developed world ...: having one fewer child, living car free, avoiding air travel, and eating a plant-based diet"

Ironically all these small personal sacrifices are as nothing unless we revive our own heavy manufacturing industries. The carbon produced by transporting and importing cheap foreign product should be 100% reduced. Our own product will provide much needed employment at a higher cost so our consumption will be regulated to need rather than greed. Hopefully our previous industrial experiences will enable us to make a better job of it this time around. Tear stained, short changed, youth can go into the mines and quarries willingly, in the knowledge that their physical and moral strength is enabling their future. Comrades.

But Trav, I thought you were for Dr. Fox/Raab/Patel's vision of no tariff, no standards "Singapore of Europe / Global Britain"? But turns out you are an Autarky Kipper. All the bluster hides a deep split in the Brexiteers.

Just been reading an article on the Guardian ( here) about the CCC report published the other day and noticed this: "New trees are the simplest solution but tree planting must triple from today’s rate, the CCC said, meaning more than 107 hectares (267 acres) a day of new forests from now until 2050"
So, that's more than a square kilometre of forestry to be planted every day from now to 2050. I'll believe that when I see it done.
