8th warmest December in 129 years of the NASA global ground record
In the real world,
outside the fossil fuel industry's spin and lies,
global mean surface temperatures continue to rise.
Please see:
http://www.metoffice.gov.uk/corporat...20080923c.html
These globally averaged temperature data come from
NASA:http://data.giss.nasa.gov/gistemp/tabledata/GLB.Ts.txt
They represent the results of tens of millions of readings
taken at thousands of stations covering all the lands of the
Earth over the last 129 years. Yes, the data are corrected
for the urban heat island effect.
The most recent 193 continuous months, or 16 years and 1 months,
on this GLB.Ts.txt data set are all above the 1951-1980
data set norm of 14 C.
There are 1548 months of data on this data set:
-- 755 of them are at or above the norm.
-- 793 of them are below the norm.
This run of 193 months above the norm is the result of a warming
world. It is too large to occur by chance at any reasonable level
of confidence. A major volcano eruption, thermonuclear war, or
meteor impact could stop this warming trend for a couple of years,
otherwise expect it to continue.
Neither Roger nor NASA types must get outside much. They actually
think it has been warm. Rog, any chance they screwed up this data
too? They have made it a habit.
Why do such inane snipes remind me of a frog in a pot.
Take a good look at the link that was provided above, specifically the graph
showing the global average temperature anomaly from 1975 to 2007, relative
to the 1961-1990 average. . Where is the cooling?
Quote: In La Niņa years - when cold water rises to the surface of the
Pacific Ocean - temperatures can be considerably colder than normal.
Volcanic eruptions can also cause temporary drops in global temperatures
because of huge amounts of dust thrown high into the atmosphere that reduce
the amount of sunlight that reaches the surface. A La Nina was present
throughout 2007 and much of 2008; despite this temporary cooling, 2008 is
currently the tenth warmest in the global record.
Quote: As a result of such fluctuations, global average temperature trends
calculated over ten-year periods have varied since the mid-1970s, from a
modest cooling to a warming rate of more than 0.3 °C per decade. Similar
behaviour is also seen in individual model predictions of future climate
change where the long-term warming trend is forecast to exceed 2 °C per
century. Even then, due to the natural variations in climate, we expect to
see ten-year periods both globally and regionally with little or no warming
and other ten-year periods with very rapid warming. This complex behaviour
of the climate system shows why we need to examine much longer periods than
ten years if we are to fully understand and quantify how the climate is
changing.
Jumping on short term coolings to deny AGW shows a large degree of
ignorance. It's a little bit like saying the day's not so hot everytime the
sun goes behind a cloud.
