True, but very deceptive.
(another argument is that:
no Global Warming has taken place since 1998.
True but deceptive enough to be a lie)
In 1998 the anomaly from the 1951-1980 base was:
0.54°C none of the years 1999 to 2010 have a greater anomaly.
But all the years 1998 through 2010 have been warmer than the
1951-1980 base. In fact, the least year is the year 2000 at
+0.30°C above the 1951-1980 base. And then for good sport,
the year 2000 ties with 1995 as the 13th hottest year 1850-2010!
That fact also says that 137 years were cooler than the LAST
year of the Second Millennium (1001-2000) after Christ.
The first evidence of 'heating' (the kind of "heating" intended
by people who think "no Global Warming has taken place since 1998"
is a meaningful statement):
The temperature of the Earth increased 0.15°C in 1851 compared to
1850. But one year as a base does not help with long
term trends.
[
the absolute value of the 1850 anomaly
MINUS the absolute value of the 1851 anomaly
EQUALS the temperature change:
|-0.44°C| - |-0.29°C| = +0.15°C ]
Lots of information on that chart, and we haven't even gotten to
the ease of computing five year averages with a spread sheet.
Yep, that is what that dark black line is -- points on the chart
at the year where one added: the year +2 years before + two
years after and all that divided by five.
The five year averages show that f
rom 1980 to 2010 the five year
average yearly temperatures of the whole earth have been
above [Warmer Than] the 1951-1980 base.
The five year averages show that from 18 to 2010 t
he five year
average yearly temperatures of the whole earth have been
below [Cooler Than] the 1951-1980 base.And the chart has a sign that a 5-year running average is the black
Line. At the end of the chart, we really
do not know what the Global Temperature for 2011 will be,
nor the Temp for 2012. So the black line just repeats the
2008 "five year average" number in 2009 and 2010. That makes
the number for the last three years flat. (also notice that
the line starts with 3 repetitions of the third "five year aveage"
for 1852 = 1851 = 1850 - the flat dark black line at the left side.
Note that the flat spot on the "five year average" line is easy
to see. Charts & Graphs made by folks who do not know their
measurement, data control, and graphing science -- their "oops" is
easy to see.
