Lot's of methane from rotting garbage in Landfills and the intestinal tracks of most animals including humans.

Though ostensibly worse than CO-2 as a putative "Greenhouse Gas" methane is probably not the cause of any warming that is occurring. If there is warming, it is due to naturally recurring cycles in the weather pattern, solar output, orbital precession and axis tilt. Temperature cycles, if they exist, will swing back the other way, and we will return to 15 foot snow drifts in Illinois as we had in the early 80's.

I view the hoopla over "Warming" just as stupid (ignorant ?) as the panic over the Year 2000 (Y2K) non crisis which, as now, only enriched financially those vowing to tilt vigorously at these windmills.

Arctic methane gas emission 'significantly increased since 2014' - major new research .
http://siberiantimes.com/ecology/others/news/n0760-arctic-methane-gas-emission-significantly-increased-since-2014-major-new-research/
The East Siberian Arctic Shelf was venting at least 17 teragrams of the methane into the atmosphere each year in 2013. A teragram is equal to 1 million tons.
It's now venting even more!
This is what happens when the global temperatures are rising, in particulary in the Arctic regions, both in the atmosphere and in the seas.
And it is NOT due to naturally recurring cycles in the weather pattern, solar output, orbital precession and axis tilt.

Temperature cycles, if they exist, will swing back the other way, and we will return to 15 foot snow drifts in Illinois as we had in the early 80's.

Does not explain away the glacial decline.

What is it then, and what can you possibly do to stop whatever it is in an industrial and industrializing world of 7 Billion population and growing.?

Does not explain away the glacial decline.

If they are declining more than in recent times then it is due to warmer temperatures. Now what explains the temperature warming in this region. I believe more solar energy is impinging on the Earth now than was the case in the recent past. If the causes were CO-2 and Methane, then the human contribution to these gases is minimal, and we could not reduce them in any meaningful way without destroying the population and way of life as we now know it.

NASA STUDY FINDS INCREASING SOLAR TREND THAT CAN CHANGE CLIMATE


Since the late 1970s, the amount of solar radiation the sun emits, during times of quiet sunspot activity, has increased by nearly .05 percent per decade, according to a NASA funded study.

"This trend is important because, if sustained over many decades, it could cause significant climate change," said Richard Willson, a researcher affiliated with NASA's Goddard Institute for Space Studies and Columbia University's Earth Institute, New York. He is the lead author of the study recently published in Geophysical Research Letters.

"Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century. If a trend, comparable to the one found in this study, persisted throughout the 20th century, it would have provided a significant component of the global warming the Intergovernmental Panel on Climate Change reports to have occurred over the past 100 years," he said.

So game, set, and match then eh?

If you google "temperature vs solar activity" you can get many links and pictures, like this one;

All of them question your belief that the suns output has risen. If you look at http://www.skepticalscience.com/solar-activity-sunspots-global-warming.htm (I judged too big to show here) it definitly show that solar output has actually reduced over the last 30 years.

William I though your smarter than that if as you say it because of things like orbital progression then why is the Temp increasing when we know the orbital progression says we should be in a Ice age

so please explain this contradiction

Just on 2 cycles left , can you tell me what cycle I'm talking about and why I say that

give you a clue the ice cores tell us some thing about what happens and how long it can take and it's not long , less than 1 lifetime .

Now what explains the temperature warming in this region. I believe more solar energy is impinging on the Earth now than was the case in the recent past.

really umm maybe this is wrong then

1/2 way down the page you will find the current solar cycle and there predictions I suggest you read the whole thing

Duh?

Well we can work to exacerbate that.

We do however need to bear in mind that that article was produced in 2003. There are more recent NASA reports since then. All of which say that man's influence is greater than the variations in the solar output. But that solar variation can produce local, but not global, variations, usually where there is low cloud cover.

Please remember NASA believes in AGW.

Please remember NASA believes in Science and can see directly everyday from the ISS what is happening so they don't believe in AGW they know it's happening from the science

You would believe NASA if they said there's life on Mars but won't believe the science of GW that NASA has done .........

So game, set, and match then eh?

Yes that is correct. If we are warming and it is not cyclic but endemic we will continue on the same path. I say this because regardless of the cause, Solar impingement or Greenhouse gases we can't do anything about them that matters.

I think that water vapor is the most significant "Greenhouse" gas--but if you like you may add Methane and CO-2 (??). In this case mankind contributes somewhat less than 5% to any of these and can't reduce even this small percentage by any appreciable percent without further ruining the economy and way of life of industrialized nations.

So you say, what's to do ?

Build seawalls; (worked for the Dutch)
Enjoy the Northwest Passage for improved trade
Move Northward
Invest in Nuclear power
Super-insulate your homes
Buy electric autos (Got yours yet?)

Not sure what you mean by water vapour effect.

Locally, in the daytime, clouds will reflect heat and light back into space and reduce the surface temperature. But the opposite happens at night because the cloud acts like a blanket.

And it was found on the days after 9/11 the temperature in the US went up because the artificial clouds former from vapour trails stopped forming as all flights were grounded. Which would lead to the theory if there were more water vapour, clouds, then the surface temperature would decrease.

Separate matter, Pew Research - The Politics of Climate

Polarized views about climate issues stretch from the causes and cures for climate change to trust in climate scientists and their research. But most Americans support a role for scientists in climate policy, and there is bipartisan support for expanding solar, wind energy

N.B. Long read

In this case mankind contributes somewhat less than 5%

5% of the Co2 and methane .

where is your poof of this statement .

We are adding at least 30% of the co2 and in studies just released it's 80% methane through our farming practices so where do you get 5% from

then the surface temperature would decrease.

That's right and what I have been saying for many months now. Gases that absorb or block sunlight will tend to cool the Earth. Since sunlight contains many frequencies --it spawns an argument over which ones get through in the first place and which ones are absorbed on the re- radiation in the infra red.

In any event, those of us who used to heat our swimming pool will notice a bigger drop in temperature of pool water when the night is crystal clear as opposed to overcast. Theories may evaporate (pun) when experience puts the lie to shoddy science.

So how is water vapour causing global warming then?

What gases does cool the Earth?
Certainly not water vapour that is the most abundant greenhouse gas in the atmosphere.
Yes, water vapour form clouds that block sunlight.
And it will be more water vapour and more clouds when the global temperature rise due to higher level of CO2 and Methane.
But that's a local phenomena.
There will be some regions on Earth that will be get warmer and some get coolder because of that.
