With solar activity currently in the grey zone near the end of cycle 23 and full aggreement not yet in as to if we have started on 24, it is interesting that there are strongly contrasting views as to how strong the next 11 year cycle will be. Here are two views from either end of the spectrum.

Icebergs near New Zealand, not as far north as in 1890’s
Two news items below report icebergs 260 kms south of NZ. Many sailing ship records from the 1890’s recorded icebergs much further north in the Southern Ocean, note 44 degrees south is near Geraldine, just south of Christchurch. Read my page;

Cover Great Barrier Reef with shade cloth ? ?
Yes this proposal to cover some of the GBR with shade cloth has actually made national news (article below) in Australia and is commented on at Federal CABINET level.
We are saying that if the GBR is suffering from GW, then surely this must be revealed in the long term temperature data from Willis Island, 400 kms plus east of Cairns. Clearly Willis island has experienced no warming trend in 67 years.
still being talked about 20 August 2012 –
Shade cloth could be used to protect coral reefs, scientists say

Decorated Scientist Defects From Belief in Global Warming – Caps Year of Vindication for Skeptics
October 17, 2006
Washington DC – One of the most decorated French geophysicists has converted from a believer in manmade catastrophic global warming to a climate skeptic. This latest defector from the global warming camp caps a year in which numerous scientific studies have bolstered the claims of climate skeptics. Scientific studies that debunk the dire predictions of human-caused global warming have continued to accumulate and many believe the new science is shattering the media-promoted scientific “consensus” on climate alarmism.
This is a lengthy post, Continue reading US Senate Majority Press Release slams “global warming” alarmism
What integrity is there in global SST trends ?
I made this map of sea surface temperature (SST) trends at the GISS website module, and it shows the 27 year trends 1979-2005 for an SST dataset GISS names HadReyn_v2 which I take in to mean the Hadley Centre version 2 SST’s with Reynolds data grafted on post 1982.
There may be another explanation of exactly what the dataset is but for sure it is the SST data Jim Hansen’s GISS group chooses to use.
I have annotated several warm anomalies that caught my eye and have compared UAH satellite trends over those warm patches with the the combined land sea HadCRUT2 data calculated at www.co2science.org.
See the Table for stunning differences in HadCRUT2 minus MSU, up to 1 degree C in 27 years !! The table also sets out the Lat & Long for various five degree grid cells that include these warm SST patches. For some history of the development of the SST datsets go to my page showing graphics of huge corrections required in raw SST data.
US expert finds hurricane intensity under-reported in early years
This article from news.com.au is timely just after my post re a drop off in Australian deaths from climate disasters.
This is the Dr Chris Landsea who resigned from the IPCC some time ago because he was not being listened to. Heavens above, why would anyone expect the IPCC to listen to an expert. Continue reading US expert finds hurricane intensity under-reported in early years
Long term reduction in Australian deaths from, bushfires, cyclones and heatwaves.
The data for this graphic is sourced from the Emergency Management Australia (EMA) online Disasters Database. www.ema.gov.au/ema/emaDisasters.nsf
Added 8 August, I have just heard of this 2006 report by Dr Indur M. Goklany of the US Dept of Interior, “Death and Death Rates Due to Extreme Weather Events: Global and U.S. Trends”, 1900-2004. See entries at the Roger Pielke Snr Blog.
Interesting that huge reductions in all categories of deaths are against a greatly increased population compared to pre WWII.

Antarctic Peninsula warmer in mid-Holocene
Some interesting papers from an AGU conference.
“Mid Holocene Warmth in the Antarctic Peninsula: evidence from the Vega Drift”. So, 4000 to 7000 years ago this area was warmer than now.
Jumbo piston core NBP0003-38, a 20.53 meter core from the Vega Drift (Erebus and Terror Gulf, northeastern Antarctic Peninsula), contains a high resolution record of climate extending back ~8500 years. Lithologic and foraminiferal data presented previously document mid-Holocene conditions warmer than today. These data include increased clay concentration, higher concentrations of ice-rafted debris, and higher magnetic susceptibility below ~6000 ybp, the consequence of extensive meltwater and iceberg calving. This change in lithology is accompanied by the presence of a benthic foraminferal assemblage characteristic of the western Antarctic Peninsula, as contrasted to a lower productivity assemblage observed in the upper section of core. New diatom data confirm mid-Holocene warmth, as based on analysis of the distribution of the two varieties of the species Eucampia antarctica. They are distinguished by their symmetry, with the asymmetric E. antarctica var. antarctica characteristic of subpolar waters and the symmetric E. antarctica var. recta a polar form. Increased relative abundance of the sub-polar form occurs between ~4000-7000 ybp, overlapping and then post-dating the time interval characterized by increased ice melt. In addition, the ratio of terminal to intercalary valves was analyzed. A direct consequence of chain length, a function of the amount of growth, this ratio has been used to record oscillations in winter sea ice cover. Data from JPC38 show longest chain lengths (and least winter sea ice) from ~4000-7000 ybp, in concert with the dominance of the sub-polar form of the species. These data suggest the possibility that mid-Holocene warmth at this site was associated with the southward migration of sub-polar waters and consequently less winter sea ice.
So much for all the years of the British Antarctic Survey beating up warming trends from station data there.

Another interesting paper mentions an active undersea volcano in the area. “A Benthic Invertebrate Survey of Jun Jaegyu Volcano: An active undersea volcano in Antarctic Sound, Antarctica”.
Jun Jaegyu volcano, an Antarctic submarine volcano, was dredged in May 2004 during cruise 04-04 of the RV Laurence M. Gould to determine rock, sediment composition and marine macroinvertebrate diversity. The objectives of this study are to examine the benthic assemblages and biodiversity present on a young volcano. The volcano is located on the continental shelf of the northeastern Antarctic Peninsula, where recent changes in surface temperature and ice shelf stability have been observed. This volcano was originally swath-mapped during cruise 01-07 of the Research Vessel-Ice Breaker Nathaniel B. Palmer. During LMG04-04 we also studied the volcano using a SCUD video camera, and performed temperature surveys along the flanks and crest. Both the video and the dredge indicate a seafloor surface heavily colonized by benthic organisms. Indications of fairly recent lava flows are given by the absence of marine life on regions of the volcano.
We are looking for more data.
Little net change in Arctic sea ice extent in 110 years ?
The Oldham Skeptic has sent in more information for Coolwire 16 based on the latitude where Nansen moored his ship the Fram to pack ice north of Siberia in September 1893. Maps of the median sea ice edge for 1979 to 2000 suggest that Nansen may not have been able to drive the Fram as far north in modern times.
