Capilot is correct: This is temperature *anomaly* -- the difference between the temperature at the point in time the video's showing and some reference temperature (which is, for GISS, the average of all temperatures between 1951 and 1980). That's why that timespan has the most white (zero anomaly) areas.

There is a difference between temperature anomaly and absolute temperature.

Muy fácil BatchDrake... si en el polo note había una temperatura de -80ºC y 10 años después había solo -50ºC se ha producido una oscilación positiva de 30ºC... Si en el África ecuatorial la oscilación ha sido desde +30ºC a +40ºC la oscilación tan solo ha sido de +10ºC

En resumen.. ese gráfico indica oscilaciones de temperatura no la temperatura en si misma..

It would be wise to look at the Global temperatures today as abrupt cooling has set in and our Sun now mimics the Dalton minimum..

2011 Arctic sea ice extent 36 % Below normal  !!

@mphello ... the deniers are a hopeless bunch of dangerous zombies tied into their coal-industry-funded cult; we'll just have to arrest them and throw them into prison for committing treason against the United States and crimes against humanity)

is not to focus so much on this single variable of temperature: since, after all "6 degrees out of 273" doesn't sound like much, but upon the TOTAL ADDITIONAL ENERGY (in terajoules) absorbed by the oceans and air caused human emissions.

I have always been stunned by how STEADY earth's climate has been (say, before Industrial Revolution): this tiny little ball out in the vacuum of space with an avg temp of 3 K separated from the sun by millions of miles: one would think the slightest orbital changes by an asteroid would create ENORMOUS swings in global average temp.

So, what humans are doing to it now is UNIMAGINABLY stupid.

Actually, I think a better way to get across to the public

(you can't do anything with the deniers

natural climate change nothing to do with us,

Well in my country it s 30 degrees now and that''s not normal for the time off the year

Normaly we see those temperatures in august and last winter we had a very cold winter with allot of snow (60 days)thats also not normal for our winters theres something chancing no doubt about that.

@TempestStormwind And honestly...who really cares if the earth warms up?...by then we'll be long gone. Truth is the outer crust of the earth is only a small factor in the planet sustaining itself. Now if the planet core starts to increase dramatically then I'll be worried. If I dig a hole 50 feet and it turns out to be 10C instead of 5C I'll start scratching my head. Things change...why is this concept so damn illusive to people?

[magicyte]

@TempestStormwind lol...so basically this video is telling me what I already know. I live in a prairie region...wow...what a shock that we get temp fluctuations. Videos like this complete mislead and cause hysteria for no damn reason. We are not warming up here any more than we have gotten colder in expected intervals throughout it's history. "anomaly"?...still equals bullshit since this also includes cold drops...so again...this video is bullshit.

@magicyte It's not warmer in Manitoba. Relative to the average temperatures between 1951 and 1980, Manitoba has warmed up faster than the equator.

That is what this map is showing - temperature *anomaly* (difference from some reference point).

You can find the full procedure complete with openly-accessible source code, on the NASA GISS website and in the peer reviewed literature.

We've also expected the arctic to warm faster than the equator since the 1979 Charney Report.

@oomblikkies It's common in these circles to refer to temperature anomaly. Every temperature analysis group does this - even Dr. Roy Spencer and Dr. John Christy at the UAH use temperature anomaly, and they're skeptical of climate change.

The maps are generated by NASA GISS but you can get nearly identical maps (for any given year; then composite them like this video) from the Hadley center (tinyurl /4n64pbf), which uses a different analysis (and different baseline).

Ten seconds on Google btw.
