Climate Change and CO2

[PrenticeBoyofDerry]

A little birdy told me that illegal immigrants, asylum seekers and eastern europeans, give quite a lot of co2 off.
Based on some scientific studies that I have I done, it may hold water!

 

[noseall]

but at the end of the day I'm no scientist.

No. Because a scientist would not say "at the end of the day..."

He's more inclined to use the phrase "test results have shown..."

 

[mickyg]

the way some people are going on, I think they'll soon be saying, "at the end of days" !

Cyclist's don't help. They have special cycle lanes built some are more than 4 mtrs long think of all the time and fuel lost building all these tiny bits of cycle lane all over the uk. Cyclist's sweat and fart more than me or u sitting in our van/car and, need to eat more to replace the energy they used slowing all the traffic in the rush hr. Most cycles are made in china where most of green industry is relocating to because it's tooo expensive to follow the rules of eco production anywhere else . Thats why many politicians have vested interests in eco thingy's such as wind turbines. they just closed down vectis on isle of wight and relocated to china. so our eco machines are being made in the most polluted place on earth. No wonder we got so many rich Chinese tourists wondring round.

According to scientists the average global temperature hasn't increased in the last ten years.

I wouldn't discount the met offices findings.

Ahh the good old trend lines !! Pick your period to suite your angle...

The green trend line shows anomoly of approx +0.43°C per 30 years or Should the rate of increase remain the same...1.43°C per century...
Perhaps this kind of reasoned graph, helped birth the discredited 'hockey stick' curve kicking the whole thing into terror mode !!

A graph showing the last million years or so, would tell us all we need to know.

the main reason for global warming is the lack of particulates in the atmosphere.
we stopped burning coal

 

[Donkmeister]

So, for aeons, tiny organisms were sequestering carbon dioxide in their shells in the form of calcium carbonate... over the years this became what we know as oil and gas. Trees and plants became coal and peat, two other fossil fuels.

Then, in the last hundred years we have burned massive amounts of coal, oil and gas. What does that release into the atmosphere? Bunny rabits? Cheese? Or, erm... carbon dioxide?

What comes out of the exhaust pipe of a car? What about the flue of a boiler?

It's OK though, plants and trees sequester carbon dioxide too. Oh, except we (as a species) have been cutting the trees down so we can have cheap meat. How many people in Britain have paved over their gardens?

Sure, a lot of carbon dioxide comes from natural sources but the sheer amount we produce per person is enormous. I've worked out that my house's average electrical demand is about 1 kW. That means about 2.5 tonnes of coal every year. That, plus 5 tonnes of natural gas that my boiler and hob burn every year. And the 1.1 tonnes of petrol that my car burns doing its 12,000 miles a year at 35mpg.

So, I'd reckon I'm burning the better part of 9 tonnes of fossil fuels a year. That's before I take into account the fuel used to grow my food, make the plastic wrapping, deliver it to the supermarket, heat and cool my office building, fly about on holidays and business trips, etc etc.

Scale that up to nations, continents, a whole world.

OK, so the question here isn't "do people produce CO2" but rather "Is this causing climate change"... I reckon so. The atmosphere is big, but not THAT big.

too clean

The atmosphere is big, but not THAT big.

yes it is. Human produced CO2 only accounts for 5% of the total CO2 released to atmosphere, without humans on the planet that leaves a pretty healthy amount of CO2 without any assistance. 1 Volcano eruption would pump enough CO2 into the atmosphere to make the last 100years of human contribution meaningless.
The thing is, I'm not(yet) arguing that human contribution doesn't effect the climate, but more to a point is the CO2 we keep getting told about the problem?
Methane and Nitrous Oxide are apparently 1000s of times more harmful to the earths atmosphere, but er...guess what..not easy to rake money from that by taxation so we'll not worry about that for now.
This is the trouble. Even if we were contributing to climate change, those that make decisions will still lie to us about it, so they can make the most amount of money from it.

Whenever the thing crops up - ask how much global temperature will be affected by changes in your life style !
Just for fun...

An exploration in moving from CO2 emissions to atmospheric concentrations CO2 to global temperature changes C°...

The gist...
From observational data it can been shown that from 1958 - 2006 when dividing annual emissions CO2 in Metric Million Tons (mmt) by annual CO2 concentration changes Parts Per Million (ppm) there emerges a relatively flat average of 14,138mmtCO2 / 1ppm
Over the last one and a half centuries atmos' CO2 has increased by approx' 100ppm from ~280 to ~380ppm..
Global temps' increased by ~0.8°C over same period.
100 / 0.8 = 125ppm per 1°C increase, a reasonable ball park figure... as we'll see later **

So to shift from mmt emissions to temperature change
~14138mmt/ppm x ~125ppm/C° = 1,767,250mmt/C°

UK in 1990 emitted 212 million tonnes Carbon or 776 million tonnes CO2 Note, most real data I have found relates to Carbon and not CO2 itself, so watch out when some begin swapping between the two to suite their 'wow' factor (3.67) takes place - Brown's territory!

If we reduced the above UK output to zero - zilch - nowt.
** The approximate global temp change could be 776mmt / 1,767,250mmt/C° = 0.000 439°C
Or a meaningless 4.4 ten-thousandths of one degree C ... even with the best will, calibrations 'nall (not too many of those no doubt) - measure that !!
We aim to cut that output in reality and by some obsfucation (C trading?) from 776mmt to 500mmt by 2020... A reduction of 276mmt p/a or 276 / 1767250 = 0.000 156°C around 1.6 ten-thousandths of one degree C.
----------------------------------
In UK, 'offsetting' 9tonnes CO2 emissions p/a av' per tonne £8.80
But 1 tonne responsible for temp increase of 1 x 10^-6mmt / 1,767,250mmt/C° = 5.7 x 10^-13 C°

So the cost of 1°C = (5.7 x 10^-13)^-1 x £8.8 = £1754 trillion give or take a bit! Mind you that 1° AGM could be just another illusion...
