Nature published a peer reviewed paper showing that since 2001 the planet has not warmed.
I checked all the data, and even GISS shows slight cooling since 2002. It is clear from looking at the GISS data that the cooling NH cold season, and especially the winter, is the reason the global mean is negative for a trend. For the GISS analysis, which is station based readings. Satellite and the NCDC data shows cooling ior the annual mean, but the cold season signal also shows up in all data sets, ocean land or surface readings.
You can easily check the GISS yourself. The others not so easy, but if anyone isn’t convinced by the GISS, then we might give it a try. (can’t link directly to the evidence, you have to create some yourself) All trends from GISS are for the time period. NCDC trends are decadal
GISS trend for January 2002-2014
GISS trend for February 2002-2013
GISS trend for March 2002-2013
GISS trend for April 2002-2013
GISS trend for December 2002-2013
And to save time, the GISS trend for NH warm season shows warming +.06 C
GISS trend for NH cold season shows cooling, - .10 C, which is greater than the warm season warming, hence the GISS trend for the entire year, 2002-2013 shows cooling.
The NCDC, HADcrut, MSU, RSS and Crutemp all agree with GISS, though some show much greater cooling for the NH cold season, and especially winter, -.16 C for the global trend DJF 2002-2013 from the NCDC
You can check the major data sets at woodfortrees, but not at any great level of detail.
Red is December
Green is March
Blue is January
Purple is February
And for good measure the GISS LOTI data from woodfortrees
If you disagree with any of this, we can have a debate.
If you start the trend in 1997 you can get an annual trend of +.11 C
However, the winter trend starting in 1997 is already negative.
The NCDC data show the NH winter trend from 1998 at -.17 C a decade. The SH summer trend is positive. +.01C
Which is why I used 2002, as even GISS shows a global cooling trend starting then. But many other data sets show cooling since 2000, or before.
NH boreal winter trends are negative since 1988 in large areas, all are negative since 1992. Alaska has negative trends starting in 1979, but drastic cooling since 2004 in almlost every station. (see December trend for a shocking example) But an eight year trend isn’t very important. Unless you live in Alaska of course.
Various ideas are being discussed to explain WHY it’s happening, like the paper in the first line of this topic. Yet some people are still arguing it isn’t actually happening.
How about you?
