Figure 5. Temperature reconstructions created using the 650-tree (‘alltrw’ data) TRW chronology (a) and the 130 tree (‘S88G1112’ data) MXD chronology (b). Chronologies were created using two RCS curves and were regressed against the Bottenviken mean May–August monthly temperature over the period 1860 to 2006. The shaded areas show two standard errors (see SI15, available online, for details) plotted either side of the mean where standard errors were scaled to fit the temperature reconstruction.
The TRW and MXD temperature reconstructions of (a) and (b) are compared in (c) after they were normalised over the common period 600 to 2008 and smoothed with a 10 year spline. The lower two panels compare the reconstructions using the TRW chronology (d) and MXD chronology (e) with the mean of May to August monthly temperature from Bottenviken over the period 1860 to 2006.

The data, displayed this way, reveal that far from showing a steady underlying rate of warming the global temperature has had two standstills, with curiously, the 1998 super El Nino delineating them.
In the debate about the significance of the observed global annual average temperature standstill – whose duration now stands at the past 16 years – some have argued that it has little climatic significance. Not only is it shorter than the canonical thirty years used as the minimum to deduce climatic effects, it is also unimportant because the underlying decadal rate of warming is close to the IPCC’s estimate/prediction of 0.2 deg C per decade, and that this rate of warming has remained unchanged over the past thirty years. Thus it is maintained that global warming has not stopped even though there may be a pause in the temperature increase, or as the UK Met Office put it, a recent lower rate of warming. What we have seen in the past 16 years is therefore just variation in the rate of warming and that the underlying rate of global warming is as significant today as it has always been.
The evidence for this is the average global temperature for the past three decades. The UK Met Office in their State of the Climate brochure use an oft-repeated graph that shows this underlying increase in warming.

Tom Harris joins Charles Adler to talk about a rather inconvenient chart showing global warming isn't so much a thing anymore.

The world stopped getting warmer almost 16 years ago, according to new data released last week.
The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures.
This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years.

A graph showing changes in sea in in the Antarctic from 1979 - 2012
Now there's more ice at South Pole than ever (So much for global warming thawing Antarctica!) by David Derbyshire - Daily Mail
Ice around the South Pole has expanded to cover a record area, scientists revealed yesterday – a month after saying that the North Pole had lost an unprecedented amount of its ice.
Researchers say – rather confusingly – that both occurrences are down to the ‘complex and surprising’ effects of global warming.

Figure 1.
The past 5,000 years of the GISP2 temperature history of the Greenland Ice Sheet, adapted from Drake (2012), who denoted the general locations of the Late Bronze Age (LBA), the Roman Warm Period (RWP) and the Medieval Warm Period (MWP) in their original work.
While perusing a paper recently published in the Journal of Archaeological Science (Drake, 2012), we read the author’s account of how most of the Greek palatial centers of the Late Bronze Age were either destroyed or abandoned between the 13th and 11th centuries BCE, and how thereafter – during what has come to be known as the Greek Dark Ages – the people affected by this climatic cooling suffered significantly in multiple ways until the advent of the Roman Warm Period.

Using data from the Climate Research Unit of the UEA , it appears sea surface temperatures may explain Antarctic Sea Ice at record levels.
SST in the southern hemisphere have a cooling trend of -0.068C / decade.over the last 15 years.

I decided to graph the AMO vs Arctic Sea Ice Extent vs Antarctic Sea Ice Extent. AMO data comes from NOAA, Sea Ice data comes from NSIDC.
The green is the AMO – Atlantic Multidecadal Oscillation. The red is Antarctic Sea Ice Extent. The blue is the Arctic Sea Ice Extent.
The dashed lines are the liner trends for each.
There are three amazing things:
1) The AMO trend is identical to the Antarctic trend even though the AMO is the sea surface trend of the North Atlantic Ocean! The trend are so close it is hard to see the AMO and Antarctic trends as separate items.
