I believe as a result of slight recent (since 1900) warming and increased CO2 concentrations in the atmosphere. There has been a 15% increase in global vegetation this must also mean an increase in atmospheric oxygen levels. Does anyone know if this is true or has been measured ?

Mark Hodgson, There is a significant switch to LPG for trucks in the USA. My solution would be hydrogen fuel cells for HGV and buses. Small scale nuclear plants (they already power Subs and Aircraft carrier) and power very large mercant vessels.

This is sponsored content, but relevant nevertheless. With the UK government pushing electric cars on us, what of lorries, tankers, white van man etc?

"Are trucks getting an easy climate ride?
Freight transport accounts for 27 percent of road transport greenhouse gas emissions in the EU, but so far trucks have escaped emission caps. But truck makers warn that a rush to regulate them now could damage Europe’s economy. We asked the Energy Visions community how they think this can be resolved."

"Each year, over 450 billion tonne-kilometers of goods are shipped across the European Union by road — three-quarters of total inland freight transport. While that may seem like a huge amount, trucks still represent a minority of the vehicles on the road — just five percent. But they account for a quarter of EU road CO2 emissions.

The oversized contribution trucks make to road emissions isn’t just because of their size and weight. It’s also because they’re on the road far longer than cars or vans. But although those two vehicle categories have had CO2 limits in place for years, trucks have so far escaped CO2 regulation."

EM, regarding the NI/ROI border. I appreciate it's closer to home for you than for me, but it occurs to me that as neither the ROI government nor the UK government want any change in the status of the border, the problem is caused by the EU. Yet the EU and the ROI both demand that the UK proposes a solution while failing to offer up any solutions themselves.

EM, you have my sympathy regarding the ageing process. And personally I don't blame you for flying. I could question why you drive a Vauxhall Zafira instead of something with smaller CO2 emissions. The serious point is that you are sufficiently concerned about man-made climate change to comment here on a regular basis, yet still you drive a Vauxhall Zafira and fly from Belfast to Stanstead and back. Most people, I suspect, would vaguely acknowledge (due to the unrelenting propaganda) that man-made climate change is a problem, but they're not really bothered about it. If you won't change the way you live to any significant degree, do you seriously expect the mass of the populace to do so voluntarily? And if changes are forced on them at expense and/or inconvenience, do you seriously think there won't be a backlash? The bottom line is, people don't care, or at least don't care enough to be bothered to change their lifestyles (and, to an extent at least, it seems that includes you).

As regards fracking, no comment on the Eden Project. Gareth seems to have undermined (pardon the pun) the scare story about fracking in Lancashire. This is also from the link he provided:

"The largest event that we have detected to date is a magnitude 0.5 ML event on 24 October. Earthquakes with magnitude less than 2 are not usually felt and if they are felt then by only a few people very close to the earthquake. Earthquakes with magnitudes less than 1 are hardly ever felt. The smallest earthquake felt in the UK had a magnitude of 0.5 and was felt by one person.

The BGS network of sensors across the UK routinely detects many blasts from quarry operations around the UK with magnitudes of up to around 2 ML every day."

Supertroll, please can you help with the "negative value" earthquakes/tremors recorded by the survey. I would like to understand - what do they mean?

EM, thank you, I live in an area with no public transport at all. Everybody depends on internal combustion engines, as there are no reliable alternatives.

The Ulster Transport Authority took away my railway in 1967 and bus passengers tend to complain about my need to piss in a bottle at frequent intervals.

I find my ability to minimise my CO2 footprint limited by being elderly in the UK.

Ugh! the missing link

Stewgreen:

Scottish wind power is heavily subsidised. I did a couple of comments over at NALOPKT by way of explanation. No wonder they are keen to expand the business.
