11th Warmest April on NASA's 130-year Data Set

In the real world,
outside the fossil fuel industry's spin and lies,
global mean surface temperatures continue to rise.
Please see:

These globally averaged temperature data come from NASA
http://data.giss.nasa.gov/gistemp/ta...LB.Ts+dSST.txt
They represent the results of tens of millions of readings
taken at thousands of land stations and ships around the globe
over the last 130 years. Yes, the land data are corrected for
the urban heat island effect. The sea data do not need to be.
There are few urban centers in the sea.

The last 129 yearly means of these data are graphed at

The Mean April temperature over the last 130 years is 13.973 C.
The Variance is 0.07207.
The Standard Deviation is 0.2685.

Rxy 0.818 Rxy^2 0.669
TEMP = 13.589617 + (0.005852 * (YEAR-1879))
Degrees of Freedom = 128 F = 258.851393
Confidence of nonzero correlation = approximately
0.9999999999999999999999999999999 (31 nines), which is darn close to
100%!

The month of April in the year 2009,
is linearly projected to be 14.350,
yet it was 14.44.
The sum of the absolute errors is 16.37904

Equal weight exponential least squares fit:
TEMP = 13.59389 * e^(.0004189 * (YEAR-1879))
The sum of the absolute errors is 16.31479

The most recent 182 continuous months, or 15 years and 2 months,
on this GLB.Ts+dSST.txt data set are all above the 1951-1980
data set norm of 14 C.
There are 1552 months of data on this data set:
-- 672 of them are at or above the norm.
-- 880 of them are below the norm.
This run of 182 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.
