Comments by "Old Scientist" (@OldScientist) on "Antarctic winter sea-ice reaches record lows - BBC News" video.

  1. This is a propaganda video. In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". What the BBC are reporting is an unusual weather event dressed up as the end of the world. Antarctic sea ice was at a record maximum in 2015. The BBC didn't report that as part of a climate crisis. And why don't the BBC report on the Arctic? Because there's been no warming there this summer. Summer 2023 is one of the coldest in decades in the Arctic, and May 2023 was the coldest on record there. The Greenland ice sheet surface mass balance (SMB) for the past 11 months is a massive 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). No, Auntie Beeb isn't going to report that. In addition, the extent of ice on the planet has no correlation to the concentration of carbon dioxide in the atmosphere.

  2. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.
