From JoNova (joannenova.com.au)<\/a><\/p>\n\n\n\n

By Jo Nova<\/strong><\/a><\/p>\n\n\n\n

A new paper (like so many before it) shows that the sea started warming half a century before the first coal fired power plant was ever built<\/a>, demonstrating yet again, the skeptics are right, and CO2 is irrelevant. Despite that, the world\u2019s supposedly top science journal lauded it in excitement<\/a> because it showed the world had warmed \u201cmore than we thought\u201d<\/a>, and somehow, in their brains, ipso delerium, all warming was caused by man-made CO2 even if it occurred when there were no flights, no cars, and no electricity.<\/p>\n\n\n\n

Life in 1820 was the ultimate \u201cNet Zero\u201d world: literally every flight was grounded and all petrol stations were closed for 80 years yet the world warmed.<\/p>\n\n\n\n

Absurdly, evangelistic headlines decreed the world was \u201chotter than we thought\u201d<\/a>, had breached 1.5C earlier than we thought<\/a> and three hundred year old sea sponges were telling u<\/a>s to hurry up and install solar panels. The point that the geniuses who are 99% certain didn\u2019t know how hot the 1800s were until last week isn\u2019t exactly inspiring. But the political activists at Nature<\/em> felt that breaching the Paris Agreement (before it was even made) was big news and said so in their first paragraph. All the major nations are failing to meet their Paris targets<\/a> anyway, and if the targets were expired before they were  even set, that only makes the UN look stupid.  And to top that off, somehow a thousand thermometers, ship buckets and tree rings have just been superseded by some old Puerto Rican sponges.<\/p>\n\n\n\n

As it happens the team at Nature also<\/em> seem to have forgotten they already announced in 2016 that global warming started 180 years ago<\/a>. Perhaps they don\u2019t read their own papers? (That was Abram et al).<\/p>\n\n\n\n

Really, this new paper makes a great study in just how bad current science communication is \u2014 every single person in the chain of nonsense failed to see the bleeding obvious.  The academics, the journal, the press release team and the \u201cmedia\u201d  all missed the most important message the corals were shouting from the bottom of the ocean. Humans don\u2019t control the climate.<\/p>\n\n\n\n

[Nature] The world has warmed 1.5 \u00b0C, according to 300-year-old sponges<\/a><\/h3>\n\n\n\n

By the time that official temperature records began, global temperatures had already risen by half a degree.<\/strong>
The planet has already passed 1.5 \u00b0C of warming, according to a new measuring technique that goes back further in time than current methods. At the 2015 Paris Climate Accords, nations agreed not to exceed 1.5 \u00b0C, a guardrail of climate change.<\/p>\n\n\n\n

\u201cWe have an alternate record of global warming,\u201d says coral-reef geochemist Malcolm McCulloch at the University of West Australia Oceans Institute in Crawley, who is lead author of the study. \u201cIt looks like temperatures were underestimated by about half a degree.\u201d<\/p>\n\n\n\n

Even though the paper says the warming started in 1860, the data shows it started earlier, more like 1820. Apparently the Sr\/Ca ratio is a good proxy for the temperature they say.<\/p>\n\n\n\n
