Comments by "Old Scientist" (@OldScientist) on "Scientists warn of irreversible sea ice melting in Antarctica" video.

  1. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  3. @godfreypigott  I'm afraid the paper is a bit of a 'bait and switch', so let's jump to the end as I quote the very last sentence in the paper: "We conclude that TWIS is of limited relevance to upstream flow dynamics in its current configuration, and there appears to be no reason to expect a possible disintegration of the ice shelf to meaningfully impact SLR projections over the next 50 years."

  4. @godfreypigott  You don't apparently know what I believe. Or why I believe it. Antarctica is not warming, it's cooling, with the evidence showing it has been doing so for at least 40 years, maybe more than 70 (Singh and Polvani, 2020; Bello et al, 2022; Zhang et al, 2022; Zhu et al, 2021). So no "global" warming, and no polar amplification - at least not at the South Pole. Therefore man-made climate change cannot be causing any change in the melt rate of WAIS including Thwaites. Because, you know, it would have to get warmer for the ice to melt. So if there is an increase in the movement of the ice it is coming from heat below, and that is what research suggests - geothermal flux (Dziadek et al, 2021; Martos et al, 2017). If it is hot rock melting ice, there's nothing we can do about it, of course.

  5. @godfreypigott  Not sure what a "ghost-blocked reply" is. As for me not keeping it civil, that's bollox! 😉

  6. @godfreypigott  How very interesting. I never knew that, and thank you for taking the time to respond in such detail. However, it doesn't appear to be any of my statements that have vanished into the electronic ether. I suppose it could be someone else trying to violently interject. I know that Regan, who posted the original comment, can be a bit fruity-abusive with his responses, but he thinks the world is about to end, and that he shouldn't become a father, which is a bit sad, so I sort of understand why he gets a bit uptight.

  7. @godfreypigott  Climate scientists have a terrible record on predicting. They are lauded for producing the most fanciful visions of the future. I've been hearing these ridiculous predictions all my life: 1958 the Arctic Ocean will be Ice free in one generation. 1967 there will be global famine. 1970 there will be an ice age in the 21st century. 1970 Oceans will be dead in less than a decade. 1971 50 years away from an ice age. 1972 glacial temperatures within a century. 1974 satellites show ice age coming fast. 1978 no end to cooling trend. 1979 ice at North Pole will melt in one lifetime. 1982 environmental catastrophe by 2000. 1988 Maldives underwater in 30 years. 1989 entire nations underwater by 2000. 2000 snowfall has become a thing of the past. 2004 UK climate will become Siberian. Cities will sink into the ocean. 2006 10 years until a point of no return. 2007 if no action 2012 will be too late. Also 2007 Arctic ice free 2010, or 2015, or 2013, or 5 years take your pick. 2008 the Arctic ice sheet would melt away. Also 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 Arctic ice free in 2014. 2012 snow will be gone by 2020. 2013 Methane catastrophe in 2 years because of ice free Arctic. 2018 zero chance of permanent ice in Arctic by 2022. Also 2018 humans to go extinct by 2023 from climate change. 2022 End of Snow predicted again. The people who come up with tosh are described as 'experts' by politicians. In reality, of course, even the IPCC knows, that apart from a little warming here and there, there is no objective evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None. That man-made global climate crisis is always going to happen the day after tomorrow, and it's going to be bad so pay your tithe to eco-priest-politicians.
