Average NZ anomaly for last decade using 26 C as “normal”:-

-13.35 C

Taking the mid point of 8 and 15 as 11.5 and adding to the current global average temperature (14.4), we get a “normal” earth temperature of 26 C over the last billion years.

That casts a rather different light on global and local temperature anomalies if 26 C is “normal”.

Let’s put it all in perspective

Earth’s Climatic History

Climatologists have used various techniques and evidence to reconstruct a history of the Earth’s past climate. From this data, they have found that during most of the Earth’s history global temperatures were probably 8 to 15 degrees Celsius warmer than today. In the last billion years of climatic history, warmer conditions were broken by glacial periods starting at 925, 800, 680, 450, 330, and 2 million years before present.

The period from 2,000,000 – 14,000 B.P. (before present) is known as the Pleistocene or Ice Age. During this period, large glacial ice sheets covered much of North America, Europe, and Asia for extended periods of time. The extent of the glacier ice during the Pleistocene was not static. The Pleistocene had periods when the glacier retreated (interglacial) because of warmer temperatures and advanced because of colder temperatures (glacial). During the coldest periods of the Ice Age, average global temperatures were probably 4 – 5 degrees Celsius colder than they are today.

The Easterbrook article is a thorough CO2 debunking.

Keep an eye on the “December 20, 2010″ thread about here:-

I’m attempting to account for the general warming of 0,45 C over the last century referencing appropriate papers.

O.15 C so far from TSI and I’ve found another paper that accounts for more by magnetism.

Also keep an eye on the bottom of the “NZ ETS: Analytic Negligence” thread below here:-

We’re starting to compile some info for a NZ ETS governmental review. This will be snippets from now on because Richard Treadgold will be making a series of posts for this purpose.

maybe another keeper

Professor Kirstein also cautioned against placing too much emphasis on the decade of 2001 -2010 being the hottest decade on record, believing the claim is “a joke” and saying that determining a global average is a tricky business and in the end is only a theoretical value

Fortuitously an important article and one to add to the list
Dr. Don J. Easterbrook has a guest post today on http://wattsupwiththat.com/2010/12/28/2010%e2%80%94where-does-it-fit-in-the-warmest-year-list/#more-30425
his point is to answer the question of ‘which is the hottest year on record’, we need to look at a much longer time frame‒centuries and millennia.
So where do the 1934/1998/2010 warm years rank in the long-term list of warm years? Of the past 10,500 years, 9,100 were warmer than 1934/1998/2010. Thus, regardless of which year ( 1934, 1998, or 2010) turns out to be the warmest of the past century, that year will rank number 9,099 in the long-term list.
The climate has been warming slowly since the Little Ice Age (Fig. 5), but it has quite a ways to go yet before reaching the temperature levels that persisted for nearly all of the past 10,500 years.

We’ll have to gear up for ‘the warmest year everrrr’ – the CSIRO has started already

CAN someone bring me up to date on temperatures
is 2010 the hottest year since 1880?

there’s a conv at Catallaxy Files and I don’t have time to do my research

sorry Richard should have checked; the comment is on page 3 of the comment pages and the link (at least the top one which I tried) seem to work from there
so if they’re useful some one would have to go through them one by one
I don’t have time this afternoon sorry
