CO2 levels in atmosphere hit historic high

A bit of a misleading headline since history shows levels much higher, if you
wish to go back in time far enough.

... That is if you go far back enough to a time when we did not exist and could not exist as we do now...

That ABC article covers some aspects well:

CO2 levels in atmosphere hit historic high

ELIZABETH JACKSON: Global greenhouse gases in the atmosphere have reached an ominous milestone that's unprecedented in recorded human history.

At the Mauna Loa observatory in Hawaii, the daily reading of carbon concentrations has now reached a level that hasn't been seen in more than 3 million years: CO2 levels in the atmosphere have hit 400 parts per million.

The last time it reached a level like this, temperatures rose from between three and four degrees and sea levels were between five and 40 metres higher than today.

John Connor, the CEO of the Climate Institute, explained to AM's Ryan Wittingslow why the figure is so significant.

JOHN CONNOR: Well, this is a measure of the heat-trapping greenhouse gas of carbon dioxide in the atmosphere. And humanity has had its civilisation when it's been between 200 and 300, but since the industrial revolution, we've been increasing those levels by burning fossil fuels and this has now hit a historic mark of 400, which really hasn't been seen for hundreds of thousands, if not millions of years.

RYAN WITTINGSLOW: So what are the implications of these kinds of concentrations? What can we look forward to?

JOHN CONNOR: Well look, this has been part of a steady trend upwards, and now we've passed this 400 parts per million marker in Hawaii, and the implications really are what we've started to see some of now, the climate impacts - more and more extreme weather events, greater climate risks more generally. And so this is endangering human safety, security. There's a whole host of issues here which we just need to recognise, we need to take serious action about, and I think slowly, investors and business around the world are starting to do that. But we've got to take some significant action and putting a price on this carbon dioxide which to date, companies have been polluting with our atmosphere for free. ...


That is somewhat more informative compared to the rather muted comment in our local UK press:

Scientists call for action to tackle CO2 levels

Scientists are calling on world leaders to take action on climate change after carbon dioxide levels in the atmosphere broke through a symbolic threshold.

Daily CO2 readings at a US government agency lab on Hawaii have topped 400 parts per million for the first time.

Sir Brian Hoskins, the head of climate change at the UK-based Royal Society, said the figure should "jolt governments into action".

China and the US have made a commitment to co-operate on clean technology.

But BBC environment analyst Roger Harrabin said the EU was backing off the issue, and cheap fossil fuels looked attractive to industries. ...

Blurf, a bit of my humor on what is clearly to me a non sustainable structure.

I was actually thinking about the other side. I know people in Chingwell, (oh the shame), that is inside the M25 and has underground stations and a London post code but is in Essex.

Dartford in Kent also falls into that category.

Oops, is that an amalgamation comprising Chingford & Chigwell?

There is a popular misconception that the Greater London Area covers all that within the M25. It doesn't!

Indeed it does not, just a few miles south of Croydon where I live bus passes issued by London councils cease to be valid. A place called Whyteleaf. Which is inside the M25.

For my sins I once drove buses out that way. Try explaining to an OAP that the pass they used to get to Caterham in the morning is not valid for the next 6 stops until we get back in the London area and they will have to PAY!!!

---

There are benefits to being in London. A friend of mine lives in Worcester park, about a mile inside the Surrey border, and always moans about how much fares cost him. My Freedom pass, paid for by all the London Boroughs, gives me free travel on buses, tubes, and trains within the 6 fare zones, 7 days a week. He has to pay. If my road needs repairing, Transport for London will do it, if his one needs work, Surrey County Council will have to find the money. It niggles him because we both have Surrey postal addresses!

I think this is a problem caused by London, Bus Passes AFAIK in the rest of the country allow travel evrywher except London.

I do have one but only use it for short journeyies because I suffer horrendously from travel sickness, but I know people that use theirs to travel free all the way to Coventry, and in Coventry when they stay with their daughter.

So... I guess public transport is part of the solution?... ;-)


On a related note: I've seen busses in London emblazoned with the declaration that they are cleanly powered by gas.

Just today I've seen a delivery wagon proudly boasting that it was powered by gas. (For USA readers: "gas" here means literally that, a gas, a non-liquid implying not gasoline/petrol.)

Better for less particulates and noxious exhaust pollution, but any better for reducing the CO2 produced?...

Running on compressed natural gas, the stuff we run our gas central heating on.
When your behind one of the vehicle It's like your sniffing the outside of
your gas boiler flue.... awful. There must be a problem here with the monoxide
content for as one knows this is a silent killer...don't want to get caught
behind one of these vehicles when stuck in a traffic jam.

NGV's

Thanks for that.

Well, well, well, who would believe it:

By the end of 2011, Iran had the world's largest fleet of NGV at 2.86 million vehicles...

And both CNG and LNG are less polluting than the other fossil fuels. Engines last longer also.


So why are we still killing ourselves with coal and oil?... All a fossil fuels industry conspiracy to stifle innovation and clean living?

2 very simple answers, the cost of new infrastructure and inertia.

Nick the smell you can smell is a added component lng or natural gas doesn't have a smell so they add a smell so people don't blow them self's up if there is a leak I hate it but better than lighting me fag and BOOOOOOOM

I spent a year in Iran back in 1978. The city was 6 million then and "Benzene" (gasoline) was 12 cents per liter. The air was dirty and soot permeated everything in the city which was at 6000 feet above sea level.

The State of Tennessee a year or so ago converted to Natural gas for it's State-run vehicles. Cost was about $1.00 US per gallon of gas equivalent.

LNG is good but requires high pressure tanks and a different infra structure. CO-2 is still produced but it moves you away from foreign (Middle eastern) oil

Nick the smell you can smell is a added component lng or natural gas doesn't have a smell so they add a smell so people don't blow them self's up if there is a leak I hate it but better than lighting me fag and BOOOOOOOM

Not sure what your smell is, but here the odoriferant burns. However high sulfur content natural gas does stink when burned. Sulfur dioxide.

Scientists say united on global warming, at odds with public view

(Reuters) - Ninety-seven percent of scientists say global warming is mainly man-made but a wide public belief that experts are divided is making it harder to gain support for policies to curb climate change, an international study showed on Thursday.

Here's an interesting symbiotic twist:


Rainforest plays critical role in hydropower generation

Deforestation in the Amazon region could significantly reduce the amount of electricity produced from hydropower, says a new study.

Scientists say the rainforest is critical in generating the streams and rivers that ultimately turn turbines.

If trees continue to be felled, the energy produced by one of the world's biggest dams could be cut by a third. ...

Principia Scientific is featuring an article entitled "Exposed: Academic Fraud in New Climate Science Consensus Claim." The article begins:

Authors of a new climate science consensus study trumpeted by mainstream media hacks for "proving" that most scientists blame humans for global warming are today being accused of fakery. Uproar ensued just days after publication of a controversial paper, 'Quantifying the consensus on anthropogenic global warming in the scientific literature.'

Experts whose work was cited in the paper by lead author, John Cook ... are aghast that their work has been used to justify far-fetched claims that there exists a "97% consensus" among scientists regarding human-caused global warming. Among those upset scientists cited in the new paper is Dr. Craig Idso. Idso reacted: "That is not an accurate representation of my paper."
