Re: Climate change
It's an exponential relationship.. the same way that a tyre overheats easier and need higher pressure as they wear and get thinner.

Re: Climate change
I agree with you both, however one would imagine that scientists specialising in the field would be aware of that, and have previously taken it into account.?Kwacky wrote:Simple physics, as the thickness of the ice decreases it's ability to deal with temp changes decreases so the global warming process actually speeds up
No, this is (apparently) a whole new realisation. Something to do with the ice shelf acting as a restraining band, and it's imminent collapse will have a far greater effect than they've been allowing for.

Re: Climate change
It's a complex situation which none of us fully appreciate. The ice sheet is an effect based off the constant thawing and refreezing which effectively gives a protective barrier. If the temperature increases so there's more thawing than freezing you would get an eventual melting of the protective layer.

Re: Climate change
The perma frost in Russia is also going, which in turn is releasing methane gas.
We're not doing a very good job of looking after our home.

Re: Climate change
The methane gas and CO2 bubbles released as the ice melts is a bigger problem than they originally envisaged I believe.

Re: Climate change
Methane is the largest contributor to the greenhouse gases too IIRC.
I say just pass the methane through washing up liquid and set it alight

Methane is at @ 15% when it comes to contributing to greenhouse gases.
Carbon dioxide is at @ 65% from "us"...industrial processes, heating, etc. and a further @ 15% from nature....animals, plants, trees, & what-have-you.

Re: Climate change
Whilst all of us are aware of the fires raging in Australia, and the record temperatures Kiwicrasher is suffering with of around 45 Deg, < that percentage increase pales compared to Norway.: 25 Deg above normal.!

Re: Climate change
Its a global problem and therefore needs a global solution.
No point in singling out and penalising just the hard working people of Oxford, who may have bought a diesel vehicle on the governments previous advice and cant afford to replace it and need the flexibility of car transport to juggle 2 city jobs and child care.
Sticking plaster on a gaping wound the size of a black hole. No scratch that its 0.0001% of a sticking plaster on the mother of all gaping wounds classified on the black hole scale of giganticism
Truth is it's about selling us electric vehicles and taxing us. If we were serious about saving this planet and breathable air we would have a global policy and standard, that all nations signed up too.
Ironically sh1t air and breathing problems might be the saving grace of this planet as shorter life spans might go some way to offsetting the major unspoken problem of over population.

How do you get everyone to change if everyone is waiting for everyone else to start?

But do you really think industrial areas of China are watching Oxford, waiting to follow their lead?

Re: Climate change
Once those people who live, work and use the centre of Oxford see how clean their air is, the idea will spread like wildfire, IMHO.

I'm with Duke, you do it bit by bit, leading by example. You can't change everyone but that's no excuse for everyone else to give up.

We all have the selfish gene,, it's hardwired into our DNA.
AI & Cyberdyne may eventually save the planet from us, when we inadvertently create it.?
Surprisingly I think you'll find that China is actually doing more than most to address the problemBlade wrote:

York and Bristol are doing similar to Oxford.

Duke I'm not picking on you here and your obviously on board with reducing emissions and that's great, but the reality is many are'nt.duke63 wrote:Once those people who live, work and use the centre of Oxford see how clean their air is, the idea will spread like wildfire, IMHO.
You may like to think others will see it and think awesome let's follow but I dont think they will. I honestly dont think anyone who isnt already onboard with it, will even notice, never mind give a sh1t what the air is like in Oxford.
