Global Warming...New Report...and it ain't happy news

what makes you think it's a graph of Japanese city temperatures?

if that is in fact what the graph is of

studies have shown that urban temperature trends trend upward in parallel with nonurban temps

they all have access to all the datasets

the satellite temp records of land, sea, and the atmosphere

the climate simulations and the algorithms involved

they all have eyeballs, and can see the macro changes that we all can see

If urbanisation had an effect on rising temperatures, it had always been so.

The US Weather Service has had as many as 6000 sites they drew data from, and similar numbers of sites around the world, in all climate zones, over the last two hundred years

plus ocean surface temps from virtually everywhere, because ships went everywhere for three centuries or so

plus satellites have been measuring ocean temps since the 60s, and land temps since the 70s, and their orbits cover most of the earth over several orbits, plus ARGUS measuring deeper ocean temps and popping back up regularly.

Unlike the surface-based temperatures, global temperature measurements of the Earth's lower atmosphere obtained from satellites reveal no definitive warming trend over the past two decades. The slight trend that is in the data actually appears to be downward. The largest fluctuations in the satellite temperature data are not from any man-made activity, but from natural phenomena such as large volcanic eruptions from Mt. Pinatubo, and from El Niño. So the programs which model global warming in a computer say the temperature of the Earth's lower atmosphere should be going up markedly, but actual measurements of the temperature of the lower atmosphere reveal no such pronounced activity.

I question why any weather bureau needs to be involved in the climate debate . What are their qualifications ? Last thing I knew Meteorology and Climatology were different 'ologies .

The satellites that have only started recording data 10 yrs ago ?

Abstract
A composite histogram method is used to objectively derive sea-surface temperature distribution from satellite radiation measurements for the Northern and Southern Hemispheres. Comparisons with conventional observations yield root-mean-square differences of 2°–3°K. Some of the differences can be accounted for by factors such as the coherent noise introduced by the onboard tape recorder, insufficient atmospheric attenuation corrections, and basic differences between the two types of temperature measurements.

The numbers in that 1997 story have been corrected to account for the changes in satellite orbit.

So we can agree that there was no warming up till 1997 ?

Climate experts warn the amount of light and warmth released by the sun is nosediving to levels "not seen for centuries".

They fear a repeat of the so-called 'Maunder Minimum' which triggered Arctic winter whiteouts and led to the River Thames freezing 300 years ago.

The Met Office-led study warns although the effect will be offset by recent global warming, Britain faces years of unusually cold winters.

A spokesman said: "A return to low solar activity not seen for centuries could increase the chances of cold winters in Europe and eastern parts of the United States but wouldn't halt global warming.

"Return of 'grand solar minimum' could affect European and eastern US winters."

Long episodes of low solar activity were seen during the Maunder Minimum between 1645 and 1715 and the 'Dalton Minimum' from 1790 to 1830.

They fear a repeat of the so-called 'Maunder Minimum'

An 8% chance of a return to Maunder Minimum-like conditions within the next 40 years was estimated in 2010 (ref. 2). The decline in solar activity has continued, to the time of writing, and is faster than any other such decline in the 9,300 years covered by the cosmogenic isotope data1. If this recent rate of decline is added to the analysis, the 8% probability estimate is now raised to between 15 and 20%.

There is about a one-in-five chance of the Sun entering the same kind of cooling phase that allowed “frost fairs” to be held on the frozen River Thames 300 years ago – but scientists warned that the next solar transition will not be enough to save the world from global warming.

Over 100 years of surface temperatures that confirm the satellite temperatures.

Observations of all the other things that also confirm the warming?

.5 degrees over 30 years becomes 1 degree over 60 years and 2 degrees over 100. But you will be gone by then, so you might as well be in denial now since it doesn't affect you.

That is your idiotic argument that is not supported by the facts.

There is a 15% chance that the sun will decline in activity.
