Plants need CO2 to grow, more CO2 is greening the planet, more CO2 means vegetation grows faster,  deforestation has a big effect on atmospheric CO2 as trees act as sink to store the gas.

I recall reading, not that long ago, that the UK was going to have Passivhaus regulations by 2016 and part of that was there would no gas in the house.


I'd love to improve our mid-60's house but I think it's got such fundamental construction issues - lots of cold bridges etc - that it needs knocking down and rebuilding.  I wonder who'd like to pay for that?


I've actually been in a Passivhaus near Northwich in Cheshire. It's owned by a friend of a friend and he is a bio chemist of some sort so a clever man. He bought a 3 bedroomed house and used the spare equity from the sale of a larger house to get this property up to Passivhaus standards. The sum of 85,000 seems to spring to mind but I might be wrong here. Anyway, it needs little or no heating. The insulation is on a scale I've never seen before and the windows have absolutely no draughts at all. So much so there has to be some specialised ventilation system. One figure that did stick in mind was that they spent 15 per month on all their energy needs.

Even if heating the house costs 2000 a year, the payback period at present prices is over 40 years, so a good project to prove a point but not good financially - if you bought 85,000 of premium bonds you would get a good return and still have your capital !

The best ventilation system you can fit uses a heat exchanger between outgoing warm air and incoming cool air to save wasting heat.  Air source heat pumps ( reverse cycle air conditioning ) can produce 2 to 3 kw of heat for every 1kw used to drive the pump, and work down to about -5degC IIRC.

Flats have fewer external surfaces so should be cheaper to improve *although be careful with external insulation).
My flat is a maisonette with three sides of two floors outside walls. The lounge has an area which used to be a veranda, but is now floor to ceiling single glazing. And it is in to the prevailing wind. The problem with a rental property is I am not allowed to do anything internally or externally. I even have to get permission and approval to decorate.

I had a brand new Jazz courtesy car last Sept
I had a brand new Jazz on loan last September too. It had less than 350 miles on the clock, but it was exceedingly quiet and very smooth. Mind you, I only have a Mk 1 to judge by.

15% of every human that has ever lived is alive today!
There have been 5 extinction events in earths history, where anything from 75 - 96% of the flora and fauna on earth went extinct. The asteroid took the dinosaurs and the rest were down to climate change!!

Improving them is another matter.

It's a can of worms insulating and sealing up a house that was never meant to be like that, especially in the attic.  An old builder friend is dead against cavity wall insulation if the house wasn't built with it in.  Mind you, it's rarely fitted properly (kept away from the outer brick skin) even on new houses.

Filling up the cavity can cause massive problems with damp , we had contractors in our area late 2017 trying to meet their targets   for government retro-fit cavity insulation ( the houses on our estate are about 20 years old and already have sheets of expanded polystyrene half the cavity width ).  We had an extension on the south side of house about 10 years ago and it was insulted with 75mm of rockwool battens ) last winter I decided to check the surface temperature of the internal walls on the fully insulated south side and the older partially insulated north side.  There was 0.2 deg C difference on average colder on north wall ( 1 checked in several places across both walls upstairs and downstairs ). Makes you wonder what difference the blown insulation makes, our neighbour had it done ( 1 of only 3 out 10 houses ) and said it made no difference to their heating bills.  Someone I used to work with had the cavities insulated and suffered horrible condensation and damp patches inside the house, had to buy a dehumidifier to make house liveable again..

Other daughter has a 3 cyl 1 litre engined SEAT Ateca - seems a lot of car for such an engine but it goes OK and the engine is very quiet, all but silent in the car.

It was against that car that I was interested to try the HR-V.  It's extremely unlikely she'd have gone for the HR-V but it never even got a chance.

I take the view that it is not 'the end of the Earth' but merely the end of mankind's time as the dominant species. In much the same way that the age of the dinosaurs came to an end and things changed drastically in favour of mammals, the coming catastrophe will simply change the makeup of life on Earth. Earth itself will endure.

The real problem is population growth.

Many "under developed"countries have seen a population growth of 3 times in 50 years, e.g. Nigeria or India, all of whom will become consumers of stuff.

Just read this to be (a) shocked (b) see the scale of the problem quite soon.

Engines seem to be noisier nowadays, last week I had a Vauxhall Astra 1.0 turbo petrol hire car, it drove well but was so noisy I was convinced it was a diesel till I refuelled it to hand it back, I also found Ford Ecoboost engines to be quiet raucous, I also found you had to work them fairly hard to unleash the power, so all in, not much difference from the latest Jazz really.
