2013 Global Temperatures


The_Global_Warmer

Recommended Posts

It's hard to say but methane is much higher over the arctic vs the world and the Southern Pole. Where as Co2 is spread out very well.

 

Clearly there is bump in down welling radiation from it up there but it might be way to small to quantify at this point.

 

 

But the arctic is always warmer regardless of pattern

 

As an aside, I have been looking for information about warming potential of atmospheric methane at various latitudes and seasonal configurations.

 

Perhaps the full effects of localized methane is not being realized in the arctic currently because there is a very minimal amount of solar radiation impacting the Arctic during the winter. I suspect it would have significant effects on next year's summer temperatures when thermal insolation is very high.

 

However actually quantifying how much methane there is will be quite the challenge, there has only been a modest (albeit exponential?) increase compared to previous years and the end effect may not turn out to be significant until way down the road, assuming methane release continues.

Probably not that much anytime soon according to recent studies.

The Context

Because methane is mostly well-mixed in the atmosphere, emissions from the Arctic or from the US must be seen within the context of the global sources of methane to the atmosphere. Estimates of methane emissions from the Arctic have risen, from land (Walter et al 2006) as well now as from the continental shelf off Siberia. Call it 20-30 Tg CH4 per year from both sources. The US is apparently emitting more than we thought we were, maybe 30 Tg CH4 per year. But these fluxes are relatively small compared to the global emission rate of about 600 Tg CH4 per year. The Arctic and US anthropogenic are each about 5% of the total. Changes in the atmospheric concentration scale more-or-less with changes in the chronic emission flux, so unless these sources suddenly increase by an order of magnitude or more, they won’t dominate the atmospheric concentration of methane, or its climate impact.

I apologize for my redundancy but CFS at the 18z update is up near .34C.

 

The monthly has reached .162C.  So it will probably end up correlating to a .72C on GISS.  I can't see it going above .175C before the end of tomorrow. 

 

I did not expect this.

 

EDIT:  00z update up to .36C or so on the dailies.

 

and .163C for the month.

November will probably come out with an impressively warm anomaly on GISS (probably around +0.70°C +/- .02°C). There were large parts of the world that saw November have warmer anomalies than October. The cold that occurred in parts of North America won't alter the global outcome.

What is the highest daily max temperature record on CFS? 

Prior to 2010 it had temperatures reach 0.7 pretty regularly.  According to the Weatherbell graphs, it appears that the CFSv2 has 2008 warmer than 2010, 2011, and 2012, which is pretty ridiculous.

Yes the CFS is not a measurement and so is not suitable for determining how one year compares to another (or long-term trends). However, if you calibrate GISS to recent CFS measurements, you can determine the current temperature anomaly.

Considering this, is it possible (without looking at the CFS) to find the highest daily global temperature from GISS data? So far i've only found monthly data.

UAH is the dataset that does not incorporate polar temperature anomalies?

I'm sure it has been discussed before but how does one explain the large difference between GISS and UAH?

 

As SL said, they measure two different things. The annual temperature rankings are similar but not quite the same. On a month to month timescale, however, there is almost no correlation. One can be hot and the other cold.

 

In addition, there is the difference in baselines.

What happened to the daily updates on this? Does this mean CFS is no longer showing amazing spikes of heat?

 

You'll note that two posts back Friv pointed out the dailies have

 

"taken the plunge but are still above .2"

 

and in the next post he points out that they have dropped below .2. 

 

So he did point out the plunge. Satisfied?

Been busy with tracking winter storms.

We have another one Friday. 

 

Secondly CFS is still .213C for the first third of December.  CFS dailies are slightly below zero. 

 

 

So if you think I am agenda pushing I can leave for teh month and come back on December 31st and I bet you CFS will be above .10C.  Which makes December another warm month. 

 

 

It's not like actually cool.  It's been "normal" on CFS for a few days.

I just noticed that there were daily updates for awhile, mostly about how CFS was running remarkably warm, and then after that last post about the drop - nothing for days.

 

It appears my assumption was right - the daily CFS stopped showing great spikes of warmth. And coincidentally or not, the daily updates ceased as well. :)
