Is it ever going to get less cold?

There has been no global warming since 1997.

If you have a child who was born in 1992, they will be celebrating their 21st birthday this year.

Since their first day at school, the planet has not warmed, yet they will have gone through the education system being brainwashed by the eco loons that the seas will boil and the polar bears will all die.

It's your children I feel sorry for.

Is there any weather event/climate graph that can disprove "CO2 climate change"?

It seems to me the snowfalls can be a thing of the past and heavier snowfalls can be a thing of the future and they both prove it's CO2.

Spring can arrive early, on time or not at all and it's CO2.

Britain can become a desert or a frozen wasteland and it's CO2.

It can rain lots, a bit or hardly at all and it all points to CO2.

Heatwave or lack of heatwave, CO2 mate.


What on earth has to occur or not occur to disprove this obvious nonsense dressed up as some kind of science?

Seems to me it's a religion. Nothing can prove it and by the same token, nothing can disprove it.

Last March, it was warm. And the doomsayers were out in force, claiming it was a disaster and 'proof' of global warming

where are they now ?

One post on a website entitled 'Disaster News Network (hint: maybe the clue to their interests is in the name) about the hot March 2012 hardly constitutes 'out in force'. Climatically, What matters is the trend and climate is defined as weather aggregated over 30 years or more. In those timescales the distribution curve has definitely shifted ..

“Climate dice,” describing the chance of unusually warm or cool
seasons, have become more and more “loaded” in the past 30 y,
coincident with rapid global warming. The distribution of seasonal
mean temperature anomalies has shifted toward higher temperatures
and the range of anomalies has increased. An important
change is the emergence of a category of summertime extremely
hot outliers, more than three standard deviations (3σ) warmer than
the climatology of the 1951–1980 base period. This hot extreme,
which covered much less than 1% of Earth’s surface during the base
period, now typically covers about 10% of the land area. It follows
that we can state, with a high degree of confidence, that extreme
anomalies such as those in Texas and Oklahoma in 2011 and
Moscow in 2010 were a consequence of global warming because
their likelihood in the absence of global warming was exceedingly
small.

Snowing here again

[DimPrawn]

1940's to 1970's there was a climatic shift to cooling. 1970's to 1990's there was a shift to warming. 1990's to today no overall change.

All the while CO2 rising. There's no correlation.

There was never meant to be a correlation. According to the theory, CO2 would warm the planet by 1.2c (and no one disputes that bit), then this would lead to an increase in much more powerful greenhouse gasses, notably water vapour. It is this that has been at the heart of the dispute

By now the vast increase in water vapour should have caused 25 million climate refugees and melted the ice caps, flooded London and swamped Tivalu. Snow would be a thing of the past and you would have grapes and palm trees in place of your leylandi.

Of course, the amount of water vapor in the atmosphere has actually fallen

With the exceptionally cold March all over the Northern hemisphere and some previous record cold winter months in the last 3 years, it´s becoming clear even to some of the thickest scientists that the quiet sun is causing climate change.

I take gr8 satisfaction watching the egg spread slowly over their faces.

...and it´s going to get worse....fun fun fun...

BS, it is rising exactly as projected by the models.

Between 2003 and 2008, the global-average surface temperature of the Earth varied by 0.6C. We analyze here the response of tropospheric water vapor to these variations. Height-resolved measurements of specific humidity (q) and relative humidity (RH) are obtained from NASA’s satellite borne Atmospheric Infrared Sounder (AIRS). Over most of the troposphere, q increased with increasing global-average surface temperature, although some regions showed the opposite response. RH increased in some regions and decreased in others, with the global average remaining nearly constant at most altitudes. The water-vapor feedback implied by these observations is strongly positive, with an average magnitude of lq = 2.04 W/m2/K, similar to that simulated by climate models.

and

The existence of a strong and positive water-vapor feedback means that projected business-as-usual greenhouse gas emissions over the next century are virtually guaranteed to produce warming of several degrees Celsius. The only way that will not happen is if a strong, negative, and currently unknown feedback is discovered somewhere in our climate system.

Still can't entirely decide, as there are so many variables.

I mean for example, more water vapour can lead to more or deeper snow that hangs around for longer and increases albedo, which might offset the greenhouse effect of the vapour.

But climate change scoffers should bear in mind that some past episodes of global warming have started, paradoxically, with the Northern Hemisphere getting colder for a while until the extra heat of the Southern Hemisphere spreads.
