Global warming, climate change, all these things are just a dream come true for politicians. I deal with evidence and not with frightening computer models because the seeker after truth does not put his faith in any consensus. The road to the truth is long and hard, but this is the road we must follow.
This article looks at the latest pronouncements on the Great Barrier Reef, and compares their findings with those of Prof Peter Ridd who has surveyed the reef with the Australian Institute of Marine Science for the last 35 years and has found that its condition remains broadly the same.

Dale Holliss of Bundaberg Canegrowers, National Irrigators Council and Bundaberg Regional Irrigators Group is proud to be in the Australian farming industry, in which farmers are proud and committed custodians of the land, rivers and oceans on which they live and work.
Mr Holliss, who has a strong background in environmental management, was a speaker at a public forum held on 8 October 2020 in Townsville, Queensland.
The forum was led by Marine Geophysicist Dr Peter Ridd and included KAP, One Nation and the LNP.
Labor refused to attend.
The forum was titled: Checks and balances around Great Barrier Reef marine science and the 2017 Scientific Consensus Statement.

h/t Breitbart; According to the BBC, University of York in Britain advised students who are self isolating because of Covid-19 to wait in their rooms for a minute if they hear a fire alarm, to minimise the risk of healthy people being infected as they flee the burning building.
Covid: York self-isolating students told ‘wait behind in fire’
Students self-isolating at the University of York have been told to wait in their room in the event of a fire and let others out first.
The university’s Health and Safety Services told students to wait for a minute before leaving “to allow non-isolating individuals to exit”.
In total 288 staff and students at the university have tested positive for coronavirus.
The university said it had since “updated and changed” its guidance.
However, it has not yet made it clear if the advice to self-isolating students is still applicable.

I’m personally deeply concerned about Covid-19, I don’t think we’ve seen the last of this nasty virus. But compared to the risk to life of lingering in a burning building? Seriously University of York, grow a sense of proportion – you shouldn’t have had to be told that this is a stupid idea.

Arctic sea ice has been growing steadily since the minimum extent was reached a month ago, with shorefast ice now developing along the Russian and Alaskan coastlines as ice cover expands in the Central Canadian Arctic. So while it’s true that the main pack of Arctic ice is far from the Russian shoreline, rapidly developing shorefast ice will allow bears to begin hunting seals long before ice in the central Arctic Basin reaches the Siberian shore, as they do in Western and Southern Hudson Bay every fall.
And speaking of Western Hudson Bay, it’s a very slow season around Churchill for problem polar bears (photo below) – the quietest mid-October for the Polar Bear Alert Program in the last five years and perhaps the quietest in decades (which I could say for sure if I had the records but I do not).
Average September sea ice cover was the second-lowest since 1979 but still within the 3-5mkm2 (see graph below) that polar bear experts wrongly predicted would cause the loss of 2/3 of the world’s polar bears (Crockford 2017, 2019, 2020):
Compare above to 2012 on the same date, courtesy DMI below:
Soon the shorefast ice along the Southern Beaufort will meet up with the southward advancing pack ice and the region will again be ice-covered – after an ice-free period of less than 3 months – see 18 July 2020 chart below to see when the ice left the shore:
And what a difference a couple days makes! It literally took two days for a big change in Southern Beaufort Sea ice coverage. As the chart below from the Canadian Ice Service shows, by 17 October the Arctic pack mass was connected to rapidly-developing shorefast ice along the central coast of Alaska, which means that polar bears wishing to resume hunting have plenty of opportunity to do so beginning today:
Pack ice movement into the Barents Sea this year (image at top of post) is lagging behind 2012 (below) but not by much. It is likely to be only a few days before the ice reaches Franz Joseph Land as well as the archipelago of Severnaya Zemlya in the Kara Sea (middle of the image below, third group of islands east of Greenland). However, if 2012 is any indication, it will likely be early December before enough shorefast ice develops along the east coast of Novaya Zemlya (that long, skinny island upper right of image) – where all the bear trouble was in early 2019 – which will allow bears that spent the summer on shore to resume hunting (rather like Western Hudson Bay bears in a ‘late freeze-up’ year, see discussion below). It will be later than that (January/February?) before the Kara Sea will be filled with ice.
No ice yet, of course – we wouldn’t expect ice in Hudson Bay even in the good old days of the 1980s. But the bears this year seem to be unusually mellow, content to patiently wait until freeze-up without causing much trouble, at least around Churchill. The situation might be shaping up differently in Arviat a bit further north. For your amusement, below is a video of a bear at Cape Churchill patiently killing time waiting for the sea ice:
The latest report on problem polar bears in Churchill for week 7 (below, 5-11 October) suggests a pretty boring time for Polar Bear Alert folks:
Forty-four incidents (‘occurrences’) as a cumulative total is very low for this time of year – and zero handled to date and zero in jail (the ‘holding facility’) is virtually unheard of. While last year (2019) was also a slow year for bear trouble in Churchill compared to other years, it was nowhere near as slow as this year:
Compare the last two years to 2018 (below), which was (like 2019) an early freeze-up year. In 2018, by the end of the second week in October there had already been 154 incidents, 8 bears in jail and 13 trapped and released locally:
In contrast, 2016 was the last year since that freeze-up was really late (i.e. early December) but because the bears came off the ice in great condition, by the second week in October the situation was no worse than 2018, when freeze-up was early:
Unless freeze-up is very late again this year – as it was in 1983 – this fall is shaping up to be something like 1984 in terms of polar bear problems in Churchill after a similarly late start to the season as this year (which began the last week of August). In the 1985 Polar Bear Specialist Group meeting report (Calvert et al. 1986:24), the problem bear situation in 1984 was described this way:
“In 1984, the Polar Bear Control Programme season in Churchill was from 1 September to 2 November, more than a month shorter than the 1983 season. There were 69 reported incidents, and 200 man-days expended. There was one serious encounter – a mauling in which there appeared to be extenuating circumstances.” [my bold]
Time will tell and depends on whether freeze-up comes in early November as it did during most years (but notably not all) of the 1980s.
