Or not?

Quoting:Skeptics advancing alternative explanations (hypotheses) for climate variability represent the way the researcher community used to operate, before politics, policy outcomes, and billions of dollars got involved

Surely this is not scientific and should be seriously questioned?

Quoting:One of the fundamental tenets of our justice system is one is innocent until proven guilty. While that doesn’t apply to scientific discovery, in the global warming debate the prevailing attitude is that human induced global warming is already a fact of life and it is up to doubters to prove otherwise.

Definitely global cooling here too! Hilarious!

From the information given it appears that the amount of CO2 in the atmosphere is insignificant, besides, plants love the stuff.

Maybe what should be concerning us more is localised pollution, that does have a serious impact on dense populations and pollution can be blown to other places. Not long ago there was pollution from Paris blowing over to England, more in the south I think but I had a delivery from a place further north and the driver mentioned that the pollution wasn't noticeable here as where he had come from around Sheffield.

Pollution caused by humankind is definitely a serious factor of concern! It makes me sad when I see people being indifferent about that!
And the irresponsibility that your pollution will also be affecting your neighbour countries!

Strangely, I went to the BT news site after posting about pollution in Paris which is blamed on diesel cars, lo and behold there was a new article about diesel cars! The real culprit is NO2 and goodness knows what else.

http://home.bt.com/lifestyle/motoring/motoring-news/end-of-t...

Quoting:But while diesel cars create fewer CO2 emissions, they emit significantly more deadly pollutants, including up to four times as much NO2.

Solution: Electric cars or even better (when further developped) cars fuelled by sun energy could be subsidized and promoted...

I read yesterday about an American company Telsa, which is making electric cars, are introducing a solar powered battery which can store and provide electricity for homes. As it is, home solar panels provide electricity that has to be used as produced, the surplus is sent back to the national grid, not sure how it does that as there surely has to be a cable which can send electricity in both directions. I haven't a clue how they gauge how much is sent back, the electricity company pays for the surplus electricity but isn't necessarily needed for their supply purposes, and any surplus electricity produced by electricity companies goes to waste.

The BT article shows how governments have got it so wrong! Why? They must have investigated more than the CO2 effect which can't be proven anyway, surely they knew of the much more harmful pollutants which diesel gives off? This leads me to believe the propaganda machine to get people to back certain policies for whatever reason, that could be to show they are a govt. which 'cares' about the environment when the world is up in arms about 'global warming' if there is such a thing. It would seem odd if a govt. encouraged people to buy something, giving reductions on cost of road tax, for any other reason unless there is corruption involving business.

Quoting:Drivers have been encouraged to switch to diesel by lower vehicle tax rates introduced by the Labour government in 2001 as it attempted to tackle carbon dioxide (CO2) levels.


The solar powered batteries will start to be installed in California this year, but you still need the solar panels, much of California should get a lot more sun than we do.

http://www.theguardian.com/technology/2015/may/01/tesla-anno...

Quoting:SolarCity is also running a pilot project with 500 homes in California, according to the company’s director of public affairs, Will Craven. The project uses Tesla’s 10-kilowatt-hour battery packs and can power homes for about two days in the event of an outage,


http://www.theverge.com/2015/2/13/8033691/why-teslas-battery...

A very funny take on installing solar panels in this country! There was supply companies who installed them for free, others who set up outfits and asked for a small cost of £500 like when we had a salesman visit, that would have been his commission and the company card he produced giving a website only had a home page with no working links. The govt. lowered the rates paid, but a levy charged to electricity pays for the excess electricity of which a large amount went to the installer with a small amount paid to the customer. Then there is the problem of roof tiles coming loose, birds nesting under the panels, how would you fix that?!

That was a funny article! Hilarious! The man clearly had been cheated!

The problem with the production of the solar powered batteries and especially produced 'en masse' might be pollution, probably the production of solar panels too!

Scientists have discovered a hitherto unknown cooling process which may pose a serious threat to man-made global warming theory

Quoting:According to a study by the Institute of Catalysis and Environment in Lyon (IRCELYON, CNRS / University Lyon 1) and the Leibniz Institute for Tropospheric Research (TROPOS), the oceans are producing unexpectedly large quantities of isoprene – a volatile organic compound (VOC) – which is known to have a cooling effect on climate.


Quoting:The oceans not only take up heat and carbon dioxide from the atmosphere, they are also sources of various gaseous compounds, thereby affecting the global climate.


http://www.breitbart.com/big-government/2015/10/01/global-co...

It's not only trees which take up carbon dioxide! They have known far too little to act on 'global warming' as governments have done, much damage has been done due to governments encouraging the use of diesel vehicles which we now know emit many times more harmful gases than officially recognised due to an emissions baffler illegally fitted to engines of some cars. The costs of levies to pay for global warming reduction has increased electricity bills and other fuel prices hugely, to the extent which some businesses can no longer afford to manufacture goods competitively. The steel industry is an example, a large steel works in the north of England is closing due to low prices world wide and a lack of demand, but also due to high fuel costs making it impossible to be competitive.

http://www.bbc.co.uk/news/uk-england-34377756

Imagine the knock-on effect of other businesses which rely on such a large industry for their livelihood, not only suppliers of goods and services but the local businesses where the factory employees would have spent money. Imagine how many people will lose their homes because they can't pay the mortgage.

Bad decisions in one area of government policy can be devastating to a whole community, and the effects can be far reaching.

Quoting:This discovery presents further proof that the skeptics are right: the reason that all that predicted “global warming” has failed to materialize is that it has been countered by the planet’s natural cooling effects.


Whether or not the grounds for the global warming theory are false, i don't have the knowledge to judge about that, I think we should look at the facts..it may not be caused by human activity though but a natural process, i don't know..

There have been troughs and peaks throughout the last 400,000 years. The elliptical path of the earth may have something to do with that, it's interesting to note that the peaks are around every 100,000 years or a little more. It is mentioned:

Quoting:Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.


Quoting:This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution


The Industrial Revolution started before 1950 of course, but the post war era has seen a huge increase in industry which in turn has precipitated the world population to a level which has never been before. People use energy, and people cut down forests such as in the Amazon which may have an effect on the amount of carbon dioxide which can be absorbed. The earth's population is producing more CO2 while at the same time reducing the ability to counter that. If history is a lesson to us at all, we should be looking at places which were once covered in trees and which are now barren. We can't say for sure that humans have been the cause of loss off of trees in places such as Easter Island, but it should be an example on a smaller scale of what can happen on a larger scale. Nature is a delicate cycle which has evolved over a very long time, interfere with that cycle and disaster strikes. Trees not only absorb CO2 but produce moisture which evaporates to cause convectional rainfall, thus keeping the delicate cycle in place.

A huge increase in population requires more food, the number of animals farmed just in this country would make the mind boggle. Animals produce methane, what is the effect of that?

Quoting:Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels.


http://climate.nasa.gov/evidence/

We need to look at what exactly 'greenhouse gas' includes.

Quoting:A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Without greenhouse gases, the average temperature of Earth's surface would be about 15 °C (27 °F) colder than the present average of 14 °C (57 °F).


https://en.wikipedia.org/wiki/Greenhouse_gas

Although there is mentioned the effects of warming in ice where there is high levels of CO2, we should be looking at other elements which are both man made and naturally occurring.

Methane:

Quoting:It is the simplest alkane and the main component of natural gas


Quoting:Occurrence

Methane was discovered and isolated by Alessandro Volta between 1776 and 1778 when studying marsh gas from Lake Maggiore. It is the major component of natural gas, about 87% by volume.


Quoting: Methane is created near the Earth's surface, primarily by microorganisms by the process of methanogenesis. It is carried into the stratosphere by rising air in the tropics. Uncontrolled build-up of methane in the atmosphere is naturally checked – although human influence can upset this natural regulation – by methane's reaction with hydroxyl radicals formed from singlet oxygen atoms and with water vapor. It has a net lifetime of about 10 years,[55] and is primarily removed by conversion to carbon dioxide and water.

Methane also affects the degradation of the ozone layer.[56][57]

In addition, there is a large (but unknown) amount of methane in methane clathrates in the ocean floors as well as the Earth's crust. Most methane is the result of biological process called methanogenesis.


Quoting:In 2010, methane levels in the Arctic were measured at 1850 nmol/mol, a level over twice as high as at any time in the 400,000 years prior to the industrial revolution.


Quoting:A Bristol University study published in Nature claims that methane under the Antarctic Ice Sheet may yet play an important role globally. Researchers believe these sub-ice environments to be biologically active, in that microbes are converting organic carbon to carbon dioxide and methane.[59] Possible adverse effects projected as the gas escapes into the atmosphere are estimated to have the potential of a sixty trillion dollar impact on the world economy.[60]


Quoting:Methane has a large effect for a brief period (a net lifetime of 8.4 years in the atmosphere), whereas carbon dioxide has a small effect for a long period (over 100 years). Because of this difference in effect and time period, the global warming potential of methane over a 20-year time period is 72. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases (these gases don't include water vapor which is by far the largest component of the greenhouse effect).[64] Usually, excess methane from landfills and other natural producers of methane is burned so CO2 is released into the atmosphere instead of methane, because methane is a more effective greenhouse gas.


https://en.wikipedia.org/wiki/Methane

An interesting chart giving percentage of "Agricultural methane emissions" for each country:

http://data.worldbank.org/indicator/EN.ATM.METH.AG.ZS

Quoting:Methane (CH4) is the second most prevalent greenhouse gas emitted in the United States from human activities. In 2013, CH4 accounted for about 10% of all U.S. greenhouse gas emissions from human activities. Methane is emitted by natural sources such as wetlands, as well as human activities such as leakage from natural gas systems and the raising of livestock. Natural processes in soil and chemical reactions in the atmosphere help remove CH4 from the atmosphere. Methane's lifetime in the atmosphere is much shorter than carbon dioxide (CO2), but CH4 is more efficient at trapping radiation than CO2. Pound for pound, the comparative impact of CH4 on climate change is 25 times greater than CO2 over a 100-year period.


http://www3.epa.gov/climatechange/ghgemissions/gases/ch4.htm...

The necessity of feeding the world population, the necessity of industry to provide jobs which in turn provide a better standard of living, and the necessity of fuel is an overriding factor when governments 'inform' the people of what causes what. In truth, the world is over populated and this brings dilemmas on how to control 'greenhouse gas' emissions. We are never told the truth! The world has many smaller wars going on, the last century saw two world wars with big reductions in population, the future may yet again see world wars with even bigger population reductions. With nuclear power that is never going to be a good idea, however the possibility remains. Man has been effective in stopping mass deaths from plagues and viruses, we now see new, stronger viruses emerge, once more the future of man may be in jeopardy from a yet to be seen killer virus which man cannot control.

Did that cheer you up? Hilarious!
