Do planes have any effect on climate?

Gackt said:
Of course planes have an affect on the planet, be that weather, or climate or otherwise. Anyone who says no hasn't quite thought it through.

Do Aeroplanes run on dreams? Are they piloted by magic? Is fuel processed/refined and transported by fairies?

Seriously, people. SEAREOOSLY.

it's more the water vapour that's an issue :o:p

I just put this comparison together, looks quite clear what effect they have on our skies!

Not buying that it looks photoshoped,

skys have looked amazing the last couple of days though :o

I really don't care about planes though, they are essential to global growth, maybe they are used a little too much short haul. But business would just fail horribly without them.

The earths reset switch is under the north pole under a ton of ice, so when that melts we can start again how fun.:o

It wasn't photoshopped, i used paint.net. :p

Seriously though you can see the original sat images yourself here and here!
 
Wow, aggression.

Can't say i'm shocked though. Same people, same responses if you don't share their viewpoint.

The effect the o/p asked about is global dimming, as Nix has posted. Observed temperature fluctuations day to night increased so it was warmer in the day and colder in the night but net it was about a degree C warmer in the day.

Actually there is no mention of "global dimming" in the OP. He simply asked about temperature changes - that can be interpreted either way.

But then this is pretty standard rhetoric from people like you.

I tell you what, since you DON'T know what you're talking about, why don't you go away.

Fair enough, as I don't really want to get the OP's thread closed. Pity, normally your posts are of an actual semi-decent quality. Still, we all have bad days, eh?

I can tell you with almost complete certainty that planes make absolutely zero difference to the climate, just as is the case with cars, ships, and other CO2 emitting machines.

With the release of the revised statement[85] by the American Association of Petroleum Geologists in 2007, no remaining scientific body of national or international standing is known to reject the basic findings of human influence on recent climate change.

I take it you know something they don't?
 
As mentioned above, the temperature actually went up when the planes stopped flying, the vapour trails (which are water vapour), block some of the suns rays. This is a short term effect, the long term effect of the CO2 produced is in the air, frankly, nobody can agree, and there's acres of corruption and bad science in the mix.

However, the earth has been undergoing drastic climate changes since loooong before we were around. Just because a lake disappears doesn't mean we did it. Just because the mean temperature was going up, doesn't mean we are responsible.

There is evidence that we have an affect on aspects of the climate, there's well documented and strongly proven theories in fact. There's the temperature after 9/11 and the "global dimming" thing, after we took measures to reduce the particulate output of transport and industry, the earth got brighter, and hotter, possibly as a result of being brighter.
 
Come on man. You accept that particulate output caused a brightening and heating (at very low concentrations, though I can't find any exact numbers), yet a rise in CO2 concentration from 270 ppm to 387 ppm (and rising rapidly) will have an affect that "nobody can agree"?

Every scientist not on the payroll of oil giants (Exxonsecrets is illuminating) agrees that the huge amount of CO2 being released by humans is going to have a warming effect on the Earth. Simple as that.

The climategate stuff was overblown by climate skeptics. From wikipedia
The report of the independent Science Assessment Panel was published on 14 April 2010 and concluded that the panel had seen "no evidence of any deliberate scientific malpractice in any of the work of the Climatic Research Unit." It found that the CRU's work had been "carried out with integrity" and had used "fair and satisfactory" methods. The CRU was found to be "objective and dispassionate in their view of the data and their results, and there was no hint of tailoring results to a particular agenda." Instead, "their sole aim was to establish as robust a record of temperatures in recent centuries as possible."

Saw a graph the other day that claimed the Volcano spewed 15,000 tons of CO2 into the Atmosphere each day, whilst the combined total of Flights over Europe placed 344,000 tons (or thereabouts) of CO2 into the Atmosphere.

Cannot recall exactly where it was and obviously I'm sure the figures may well be estimates.
 
The thing that you need to remember though is that volcanism is a natural influence; it's been doing it for many, many years and will continue to do so with us or without. Our influences are new and not natural in the planetary sense. Compared to some inputs, ours is moot but it is still a significant one. It follows then, that a significant and new input into an otherwise 'stable' system is going to produce unexpected results or runaway positive-feedback mechanisms long before they were naturally due.

This is what many of us keep trying to explain and what the genuine science is pointing to: we're playing dice.
 
Has anyone started to see the hidden lizardmen now the population mind-controlling substances from the chemtrails is starting to wear off?
