Global Temperature Maps for today

[Halbhh]

While you can see the cold here today:

Actually it's warmer than normal for this day in the year in some areas to the north, including a big part of northern Canada, and also Greenland:

The Temperature "Anomaly" is the difference between the actual temperature at the moment compared to the normal average at this day in the year.

So in the Anomaly map, you see blue where the temperature is colder than normal for today, and red for areas where the temperature is warmer than normal for today.

So in the Anomaly map, you see shades of blue where the temperature is colder than normal for today, and shades of red for areas where the temperature is warmer than normal for today.

That's what you get when the jetstream collapses, the arctic air breaks out and turns europe and the USA into freezers.

That's right and although it is three weeks behind as all season has been,this is what we call winter on a normal and yearly basis. The temps are the same but just a little later than normal. Happened the same a hundred years ago.

People might not panic as much if the media didn't play up wind chill which only effects bare skin and most people are not that stupid to walk around exposed. It also does not affect vehicles or homes so why bother trying to exaggerate for the sake of aggrandisement?

BTW.. this bubble of cold which has been trying to defy nature by moving from east to west is finally on the move and will be a statistic within days. The question in why was it so insistent on moving backwards?

Let me add that for looking at overall global temperature for an long enough time period to see a real meaningful number -- a trend -- one needs not only the entire globe averaged together, but also a longer time period than just 1 year. One needs about a 5 or 10 yr average, and on a graph that spans at least a 50 yrs or a century imo -- because of how ocean upwelling varies year to year, and it's such a powerful factor that causes individual years to zig zag in temperature.

A cold day in hell as they say ..

Nice set of maps @Halbhh - thank you.

Just a note of caution to viewers looking at this in the context of Climate Change - the anomaly map (post #2 above) can't be used to draw any conclusions about Climate Change. Comparing today's temperature with the 1979 - 2000 average is interesting but it's effectively comparing climate with weather. A similar measurement taken tomorrow could show a different set of results for areas above/below average. To make any climate conclusions requires a much bigger data set than just today.

EDIT: Looks like you (@Halbhh ) pointed this out in post #6. It sometimes takes a long time for posts to get down to my part of the world.

wow, do you think some might not realize that? ...right! Of course some would not. heh. Lemme post the graph.

 

[Halbhh]

Someone suggested above we might best want to see a long term graphic.

So...

First of all, here's the main human influence on climate (and that's mostly from one gas in particular):

[Halbhh]

The global average annual temperature zig zags up and down because the upwelling of cold ocean water from the deep ocean varies from year to year. (some years more cold water rises up, some years less)

And...the deep ocean temperature itself is rising also....

So, we take a long term average to see the real long term trend.

 

[FrumiousBandersnatch]

As I understand it, these relatively long-lasting extremes of hot and cold over the northern hemisphere are caused by the exaggerated meandering of the jet stream as it slows due to the warming of the arctic reducing the temperature gradient between the arctic and temperate latitudes... something like that

Part of the expected greater extremes of weather due to global warming.

Same thing happened almost this time of year about 125 years back. And yes the jet has been exaggerated from it's more even flow in the last few decades. But it is interesting how these bubbles of warm/cool flow about the top of the world.

Yes, it has been known to happen before; and we can expect the frequency of their occurrence to increase.

Especially as the sunspot activity increases as we are seeing now.

Sunspots come and go; it's global warming that will have the significant long-term effect.

Or cooling.. which comes and goes also. A good first step would be to stop all the soot landing in the arctic speeding up ice melt and boosting temps. But I suppose that something that simple wouldn't be as profitable to those creating new industry for profit and the fourth industrial revolution, to fix what they broke for profit in the first place.

Reducing sooty particulates would help, but reducing CO2 is the significant requirement.

I suppose so when it can be an ongoing cash cow compared to putting out an industry's own money to clean up their act.
