Would you like to present some evidence to the effect that "passive smoke" (with a precise definition of the term) is an unequivocally significant general health problem?

Wikipedia seems to do a good job.

Right: Most of the research has come from studies of nonsmokers who are married to a smoker

It's no surprise that folks who breathe while routinely confined in close quarters with cigarette-smoking spouses or coworkers would suffer harm — that seems about as concentrated as it can get. Also according to Wikipedia, in December 2010 Singer wrote that he is a "nonsmoker who finds second-hand smoke an unpleasant irritant that cannot be healthy," so he must have become persuaded somewhere along the line.

So have we come to the end of this ad hominem rabbit trail?

Word games. That which "cannot be healthy" must ipso facto be unhealthy.

Got a genuinely logical alternative interpretation?

(I didn't think so.)

Re: Global Warming - what's behind it?

"cannot be healthy" means it's not positive for your health. Thus it can be either neutral or detrimental.

This coming from a public statement is anything but word games. But your reply clearly shows the diligence, care and "logic" you apply.

It's pure speculation on your part that his intended meaning of the words "cannot be healthy" could have been "neutral." Maybe you mean "neutral" when you say "cannot be healthy" but I seriously doubt most of the rest of us ever would.

Like I said — word games.

Re: Global Warming - what's behind it?

http://www.iflscience.com/environmen...d-next-ice-age

It appears that through the burning of fossil fuels and filling the atmosphere with carbon, mankind has caused the world to “skip” an ice age, potentially postponing the next one by between 50,000 to 100,000 years. The new research came to this conclusion after modeling the conditions needed to tip the planet into a glacial period. They found that while Earth is at the right point in its orbit around the Sun, the level of carbon dioxide currently in the atmosphere is far too high.

Is that a positive or a negative effect?

"Not really, if it was a reflection then the frequency of the returned radiation (energy) would not change."
How many people without a math-based scientific background can say that or draw that conclusion with certainty?

"beyond a reasonable doubt" AFAIK (I'm not a native English speaker) is a legal term, not a scientific one. Or else, what probability is assigned to that term by the scientific community?

Perhaps it's written poorly but you completely misunderstood the Relativity Theory example. Take particular note of my last half-sentence

About "AFAIK (I'm not a native English speaker) " You write very well, respect.


You would cry at my written German

Re: Global Warming - what's behind it?

Here's an article from the Economist, a journal that cannot be accused of "liberal bias". This article is about the low quality of the Republican contributions to the debate.

Re: Global Warming - what's behind it?

Strange business this global warming!

I attach a graph from the IEA (International Energy Agency) about annual CO2 emissions.
The global warming theory in simple form is that as CO2 increases in the atmosphere so the global temperatures increase.

For the last half of the last century this relationship between atmospheric CO2 and temperatures worked well.

Now we have the interesting situation that annual CO2 emissions rose steadily from year 2000 to 2013 (in fact more steeply than in the last half of the last century) but global temperatures did not increase.

However annual CO2 emissions in 2014 and 2015 did not increase over 2013 but in 2015 global temperatures shot up again.

Since the proof of Global warming is by correlation not causation then one has to wonder?

1. It's a long-term relationship. Expect swings from year to year
2. 2015 had one of the strongest el-niño's ever, probably driving up global temperatures (I know this is disputed but there does seem to be a collolation between El Niño and exceptional temperature shifts. A probable La Niña in 2017 will likely pause warming next year
3. The level of emissions was roughly unchanged from 2013 to 2015 - sio we are still pumping millions of tonnes of CO2 into the atmosphere, further increasing the concentration of CO2
4. Interesting, isn't it, that your graph shows a continuous longer-term temperature increase despite the fact that solar radiation has actually tended to decrease in the same period. I wonder what could be causing it?
5. (for Sbrinz) our mean distance from the sun doesn't change to any remotely measurable extent.


You might be interested to learn that February 2016 recorded the largest ever recorded temperature anomoly. Overall the Earth was 1.35°C above average; the Northern hemisphere 2°C above.

"2015 had one of the strongest el-niño's ever" So it is el-niño's driving global temperatures; not CO2 emissions?

Nonsense! The graph shows nothing of the kind. The graph carries absolutely NO information whatsoever about temperature. It shows the quantity of CO2 emitted in gigatons against years.
Truth be told the CO2 levels shown are still quite low compared to past levels.

not even that.

It shows energy-related emissions. Energy is a large part of the puzzle here but not the only piece.

And I don't think the atmosphere differentiates between energy CO2 and other CO2. Thus the graph isn't especially relevant.

Re: Global Warming - what's behind it?

Thank you. I was trying to keep it simple.
It would be interesting to know how large the other CO2 emissions are like animals breathing (including us) and natural emissions from volcanoes etc. etc.
