As engineers we are educated in physics and chemistry and should have a reasonable idea on what really effects the energy consumption that causes climate change. I am looking for peoples opinions on what suggestions have been good ideas to reduce your individual impact. Alternatively what suggestions have you heard that are utter nonsense.

It would be good to hear comments from engineers on this matter.

Uh oh, no consensus:
Numbers vary, according to whose article you read, but around 31,000 scientists, 9000 with PhDs, most in some sort of climate or environment related discipline (it is said) have signed the petition.

That's an awful lot of people to be in the pay of the petrochemical giants.

As one diehard said "When 100% of scientists sign that's when we'll have a consensus."

Now for those who think taxation is the answer, take a look reports of "Spanish, Belgian and Portuguese fishermen launched nationwide strikes over soaring fuel prices, the latest in a wave of oil related protests sweeping Europe."
and protests in other countries about the price of fuel.

SO now let's look again at the problem and how to solve it if it exists.

Seems ironic to me that as fast as everyone is cutting down trees (not just the slash and burn merchants but also local authorities who believe trees are harmful to motorists...(from their habit of positioning themselves just where motorists speeding along at 90mph a#re going to come off the road)... that someone now suggests giant artificial trees (I wonder if they will put them up on bends in the road).
So now we have artificial trees to add to artificial volcanoes (proposed as a means to put Sulphur into the atmosphere, after we've taken it out of fuels) as an aid to global chilling.

Its a funny old world, isn't it?

Sorry, just had to add a bit.

The artificial tree proposal comes from Dr Broecker.
He said the challenge was to get rapidly developing countries such China, India and Brazil behind the idea.

The UK is littered with Palmerston's follies. These are the forts built against an expected French invasion. They were built in the 1870's at great expense.

It transpires that all the French invasion plans began with a statement "First the British Royal Navy is lured away...."
but without saying how. Dr. Broecker's "challenge" is a bit the same. Without that the Chinese agree it ain't going to happen.

OK, so the Russian Academy of Science has decided AGW is a myth. I see no reason why the Chinese should choose to believe in AGW, indeed, they have every reason to reject the idea.

Incidentally, the French Invasion scare was attributed to Napoleon the Third. Not only did the UK get all those forts and lots of orders for Armstrong but in the southern UK all houses had gravity tanks for water so that if invasion came and interrupted supplies every house would have a reserve.
As for Napoleon III, he lived out his days with the Empress Eugenie at Farnborough Hill House in Hampshire and his son was killed on active service with the British Army in Africa.

But don't expect that Al Gore should be accorded a similar courtesy should he have to flee into exile. (Britain has always been a haven for failed or threatened politicians and Royalty including Metternich who lived at Brighton for a while).

Thanks for the quote josephv. You will notice it was over 10 years ago and Earth has cooled since then...

:)
 
Interesting part of the petition

"Proposed limits in greenhouse gases would harm the environment..."

What!? How can putting less of our man made pollutants harm the environment? I would be really interested to hear that explanation.

Also there seems to be a very large concentration in certain states like texas, California and Florida, are these oil producing states?

Also interestingly only 3,697 are in Atmospheric, environmental, and Earth sciences, and there are almost 10000 from engineering and general science (some of which are probably no more informed than we are).

The petition does not convince me at all when weighed against a buch of scientists specifically picked for their knowledge of climate related issues.
 
Also, if you look at the petition itself it has a check box that says, "please send more petition cards for me to distribute".

This basically means that the distribution of petitions was relatively uncontrolled ( i.e. they could distribute the petition to anyone).
 
Most ghg emissions, namely CO2, are not "pollutants". They are the base of the food chain. So much for your paradigm.

As far as limiting their emissions being harmful to the environment, look at the results of the very first step we have done - that is encourage making ethanol. the raw materials for 25 gallons of ethanol from corn would feed an adult for an entire year. The cost of food has risen worldwide due to this calamity, therefore more people are farming less arable land, using more fertilizers etc. They are also pushing the limits on crop rotation, ruining more and more arable land.

And that's just the first step.

Then you get into not letting third world people use fossil fuels for food production, manufacturing, etc.

Contrast that petition with this one:

which they could only get *100* IPCC scientists to sign.

100.
 
The real impetus of using ethanol was not really climate change it was more to do with rising fuel costs.

The environmental 'benefits' were just a political wrapping.

If bush was really into the environment, mandating better fuel efficiency standards would have a much more immediate effect.
 
csd72 said:
"The real impetus of using ethanol was not really climate change it was more to do with rising fuel costs."

Got any backup on that? It doesn't make any sense, especially since it takes so much fossil fuel just to manufacture ethanol.
 
back to the petitions ...

1, 100, 100,000 who cares ... science is about proving stuff, having an idea about the causal relationship of some things, devising experiments to test predictions, then living with the results, possibly explaining a more complicated relationship.

politics is about getting people to believe stuff so they'll do as they are told, or let others tax the cr@p out of them.

NO-ONE can prove AGW, these day's we're having enough trouble detecting GW. Everyone has an opinion and each is to a greater or lesser extent educated. if people say "well 1,000 scientists say so, then it must be true", then they'll get the world they want.

of course the climate is changing; it's always been changing and always will, but we have no proof as to what it's going to do tomorrow.
 
Lcruiser,

Your point can also be used to argue against the environmental benefits of ethanol.

But the truth is that these are unexpected side effects that were not expected at the original inception of the idea. It can work though, as Brazil has shown.
 
csd, Native Tribes, Endangered Animals, Wildlife groups etc. may argue whether it really works.

I’m not sure if the de-forestation is linked that much to cane sugar or to cattle ranching or even subsistence farming etc but the last I heard it was continuing.

“Environmental Impacts” is a huge remit, CO2/AGW is just one part of it.


KENAT, probably the least qualified checker you'll ever meet...
 
Brazil is #1 in the world in destruction of rainforests. Even above other continents.
 
KENAT,LCruiser,

Very good points. Thats what comes from not having time to think these posts through.

I would never make it in politics.
