The global temperature has fallen .653°C (from +0.554 in March 2010 to -0.099 in March 2011) in just one year. That’s a magnitude nearly equivalent to the agreed upon global warming signal agreed upon by the IPCC. It is quite a sharp drop.
According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), global surface temperature increased by 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century

UAH Temperature Update for March, 2011: Cooler Still -0.10 deg. C
La Nina Coolness Persists
The global average lower tropospheric temperature anomaly for March 2011 fell to -0.10 deg. C, with cooling in both the Northern and Southern Hemispheric extratropics, while the tropics stayed about the same as last month. (I’m on the road in Virgina, so the temperature graph will not be updated until I return on Thursday.)

What has really changed is the pitch of the voices who claim that it’s a portent of climate catastrope. Th climate will meander lazily to the next Ice Age soon enough: No need to hasten it’s arrival with doomsday-style panic button experiments. The latter is the real catastrophe.
You guys are forgetting about the feedbacks! It’s like you believe the temps instead of the models!
I like to keep an eye on this collection of temperature readings from time to time:
http://www.athropolis.com/map2.htm
Let’s see….Resolute, Nunavut is -29F right about now. Where’s the “melt season” that NSDIC is talking about?
http://nsidc.org/arcticseaicenews/
We have built up some nice, thick polar ice over the past few years, I’m wondering if the Northwest Passage will open up again this year?
RGates says :
Interesting update…even mentioning such short term ENSO ups and downs in the context of longer term global warming seems like talking about apples and oranges. Such declines are to be expected when transitioning from a decent El Nino to La Nina.
Likewise, RGates, such increases are to be expected when transitioning from La Nina (or La Nada) to El Nino. Furthermore, a long term increase is to be expected when in a Warm PDO because El Nino’s are stronger and more frequent (1980’s – 2000), and a long term decrease is to be expected when in a Cold PDO because La Nina’s are stronger and more frequent (1950’s – 1970’s). In addition, these increases or decreases will be squelched or exacerbated depending on the phase of the AMO.
So please spare us your hypocrisy.

Are you sure they included ground cover back then?
===============================================
I think the point was only about the current state, however, it is noteworthy to compare the sea ice coverage. After 30 years of crying about the arctic ice, wailing about our impending doom, lamenting the certain demise of our polar bears and all sorts of gnashing of the teeth, can you see a discernible difference in the ice coverage? One would have expected a significant difference.
And Australia had its coldest March on record (or at least for the past 60 years).
but they promised that warmer air held more moisture and that was why there was more snow……….

R. Gates, One interesting thing to note is the anomaly was near zero when the most recent el Nino began. The entire AGW movement had all its marbles riding on the peak of that el Nino.

for a lot of long term temperature data, got to
http://www.rimfrost.no/
The have St. Helen’s from the early 1900’s, plus a lot of other long term data.
Last year I kept telling the Warmists about the coming cooling and they just didn’t want to know. It will be interesting to hear how the narrative changes over 2011. It may warm up next year though.
Well I hope this information reaches Ross Garnaut. If it does, no doubt he will consider it to be just some more misinformation that “high profile’ commentators are spreading around about global warming.

Check out that 1998 to 2011 trend!
Climate of Corruption: Politics and Power Behind The Global Warming Hoax by Larry Bell (300 pages, published Jan. 1) is free (Kindle version) at http://www.amazon.com/gp/product/B004J17AUY/?tag=thrshoguideaa-20
Warmies can tell noise from a trend because they know what the future trend is — they have models to prove it.
An unrepentant global coolist still at work with speculation since the 1970s:
Clarification:
I know that Professor George Kukla is retired. I just meant he is still working with speculation.

Try Campbell Island from well South of New Zealand.
The data can be found at the NIWA (National Institute of Water and Atmospheric Research for New Zealand) website. When you get there log onto the cliflo database which is maintained by NIWA. You will have to register but the NZ data is free and searchable.
There are about 100 datatypes to chose from in the database. Mean daily air temp (given as a monthly and annual average) is the 02 dataset. The mean max daily temp (given as a monthly and annual average) is the 03 dataset. The mean min is the 04 set. Other relevant sets are 05, 06, 07, 08 including grass max and grass min. Soil temps are the 10, 11, 12, 13, 14 and 47 sets (5 cm, 10 cm, 20 cm, 30 cm, 1 m, 50 cm).
Campbell Island data is divided into two stations (basically the same site but different equipment). The “agent numbers” that identify the sites and data in the database are 6172 and 6174. Fortunately there is a 3 year overlap. The data commences in 1941 and goes through to 2011.
The data should be the raw data though you probably will not be able to get the actual daily reports (to check) unless you make a special request to NIWA
Mango, the real climate deniers are the warmists, as they are the ones that deny natural climate change.

I think you are quite confused. By the “AGW movement”, I suppose you mean those who believe that it is more likely than not that CO2 could have a long-term climate positive forcing (warming) effect. The educated of those in this “movement” would certainly understand the short-term natural variations that come with ENSO, PDO, solar cycles, and such, and would not, in any way have “all its marbles riding on that El Nino”.
If such a long-term effect such as AGW warming is occurring, it would be most visible and the most earliest visible in the areas most sensitive to such NET global energy changes. Those areas would be the polar regions, with the the N. Hemisphere being even more sensitive than the S. Hemisphere due to the vastly different physics of the regions (i.e. the large mass of ice at the S. Pole, the differences in total insolation, the southern ocean heat sink, etc.)
Currently, the trend in Arctic sea ice, the earliest of the “bell weathers” for AGW is proceeding in the long-term way that GCM’s have indicated would happen when factoring in the long-term NET forcing of anthropogenic CO2. 2011 should give 2007 a good run for being the lowest summer sea ice extent on record. These longer term trends are far more important that what a short-term ENSO cycle is doing.

I know of no professional climate scientist who denies natural factors in climate change…both very long term, such as Milankovitch cycles, and the very short climate effects such as ENSO cycles. The real difference between skeptics and “warmists” also can accept the fact that the 40% in CO2 since the 1700’s, rising to the highest levels in over 800,000 years, could have an effect on the climate as well and can accept the evidence of that.

Any “warmist” who has been around a while knows that temps rise and fall on a short term basis with ENSO cycles. It is the longer term that is important in looking at the NET forcing from CO2, and the first sign of that would be in the Arctic– exactly as is occurring.

stevo says: “It really is appalling that you can’t or won’t learn the simplest basics of statistics. Comparing noise with trend is stupid – no other way to describe it.”
What noise are you talking about? The wide year to year variations resulting from ENSO are not noise. ENSO is a natural process that helps to reduce temperature difference between the tropics and the poles.
____
I think the point is that over the long-term, ENSO is not NET forcing event, but simply a way of balancing out heat around the planet. ENSO does not create any NET long term heating or cooling (and it better darn well not, or we’re in trouble!)
Gates says:
“I know of no professional climate scientist who denies natural factors in climate change…both very long term, such as Milankovitch cycles, and the very short climate effects such as ENSO cycles.”
Let me introduce you to a certain Michael Mann [who fancies himself a professional climate scientist]. Mann attempted to show there was very little temperature change from 1400 AD until the industrial revolution. He tried to erase the MWP and the LIA, but his attempt was debunked by McIntyre and McKittrick.
See? You learned something new today.
This is how the UAH daily temperatures have changed since the beginning of 2010.
Global temperatures have really fallen by about 0.8C since some of the January, March 2010 individual daily peaks. Tropics temperatures are down about 1.3C since the January, 2010 peaks.

I expect UAH to stay in the -0.1C range until about July.
