Is it warming or cooling?

I go by UAH temperatures

as you can see there has been no rise for quite some time. and what rise there is, is very small about 0.1 per decade

As demonstrated by Kano's link, the temperature moves up and down a lot so it really depends on where you start and where you end. We have warmed over the last hundred years by an amount that just about equals the previous hundred. We didn't cause the previous hundred so it is up to alarmists to prove we caused the last and that it is a threat. Obviously they haven't yet and don't appear to be anywhere close because it is stabilized somewhat lately.

Google: Global average temperature.

The monthly global temperatures from satellites is published by the University of Alabama Hunstville on behalf of NASA. The linear average since 1978 is +0.14 degrees per decade (1.4 degrees C per century.)

Some areas are warming faster than others. The north polar region for example has been warming at 3x the average rate; at .45 degrees per decade of 4.5 degrees per century.

Be aware this this is only the surface atmosphere temperatures. 90% of global warming goes into the oceans which are also warming. I don't know of anyone who tries to capture or calculate the global average ocean temperature but the University of Colorado Boulder measures the average sea level by satellites. Sea level has been rising, primarily due to thermal expansion as the water warms, at a linear rate of about 3.2 mms per year.

The climate varies quite a lot so to determine if it is warming or cooling you also need to specify a time period.

Off the top of my head it seems to be like this:

► Last 10 years: Slight cooling.

► Last 17 years: No change.

► Last 300 years: Warming.

► Last 10,000 years: Cooling

► Last 20,000 years: Major warming.

► Last 100,000 years: Slight cooling.

I know most people here are only concerned about the Northern Hemisphere, but down under (Australia) there is no confusion which way things are heading.

Here's some records we broke last year Yay!

Australia’s warmest month on record (January)

Australia’s warmest September on record

Australia’s largest positive monthly anomaly on record (September)

Australia’s warmest summer on record (December 2012 to February 2013)

Australia’s warmest January to September period on record

Australia’s warmest 12-month period on record (broken twice, for the periods ending August and September)

Indeed, Australia’s warmest period on record for all periods 1 to 18 months long ending September 2013

Two significant daily maximum temperature records were also set last year:

Australia’s hottest summer day on record (7 January)

Australia’s warmest winter day on record (31 August)

There's a page here with a chart, but you can't click on the chart to see the bigger version.

Warming by about 0.1 degree per decade. Of course, in order to scare the public, the warmers have to talk not about the 0.1 degree per decade of warming, but about their overparameterized overestimating exponential models that are based upon guessing.

You have to see the climate as a mixed relationship between warming and cooling, i.e. cooling leading to warming and warming leading to cooling.

It is warming.
