Climate change

[Cav]

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

[StMarks]

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

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.?
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.

[Cav]

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.

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.

[duke63]

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

[Cav]

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

Victoria Falls in Zimbabwe has dried to a trickle in worst drought in living memory.

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.

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.!

Meanwhile Trump is starting the new year afresh, and rather than dismiss climate change it seems he's now aiming to undermine any provision for consideration of environmental impact.

He may well burn in hell, but he seems keen that the world should share his fate.?

Moscow had to make snow over Xmas to make it feel like winter.

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?

You get someone way more interested and cleverer than me to sort that bit out. Or you could make the nesscary changes international law.

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

[duke63]

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.

[Kwacky]

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.

You don't.

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 problem

Visitors to Oxford will go home and demand their local councils do the same.

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.

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.
