ROFLMAO WaPo's "most rigorous reconstruction of Earth’s past [Phanerozoic] temperatures ever produced" surprises Michael Mann, says human-caused warming will not make the planet uninhabitable

The article has this response from Michael Mann:

 The timeline, published Thursday in the journal Science, is the most rigorous reconstruction of Earth’s past temperatures ever produced, the authors say. ...

Michael Mann, a climate scientist at the University of Pennsylvania who is known for his analyses of past global temperatures, said he was also surprised by the suggestion that the planet got so warm. The finding supports many scientists’ concern that feedback loops in the Earth system could lead to much higher temperatures than most climate models predict, he wrote in an email. But it’s also possible that the data assimilation assumes too much warming and is missing factors that might forestall a runaway greenhouse effect. “While I applaud the authors for this ambitious and thoughtful study, I am skeptical about the specific, quantitative conclusions,” Mann said. ...

Even under the worst-case scenarios, human-caused warming will not push the Earth beyond the bounds of habitability.

 

The article, which places us today in some of the still coolest climate conditions in 500 million years, never connects the dots.

It maintains that a dramatic warming event 250 million years ago caused the largest mass extinction ever, spewing carbon dioxide and other gases into the atmosphere, 25 million years BEFORE the first mammals appeared, who breathe the OXYGEN emitted by carbon dioxide consuming PLANTS, who then in their turn THRIVED for 125 million years under EVEN WARMER conditions than that extinction event produced.

Evolution was evidently turbocharged by this warming and its carbon dioxide, but then suddenly the first humans supposedly started to evolve 6.5 million years ago at the end of 50 million years of cooling conditions, WHEN THE TEMPERATURE WAS 62.6 F*, and continued to evolve into modern humans 300,000 years ago just as temperature KEPT FALLING to the coldest point in the record (51.8 F).

How did that happen?

The study authors are worried about what warmer conditions in the future will mean for humans, but seem oddly uninterested in how humans supposedly evolved in relatively much cooler conditions.

Maybe we don't really understand the evolution of mammals. Maybe humans are much older than the record indicates, and much more resilient.

 

At its hottest, the study suggests, the Earth’s average temperature reached 96.8 degrees Fahrenheit (36 degrees Celsius) — far higher than the historic 58.96 F (14.98 C) the planet hit last year. ...

At the timeline’s start, some 485 million years ago, Earth was in what is known as a hothouse climate, with no polar ice caps and average temperatures above 86 F (30 C). ...

For most of the Phanerozoic, the research suggests, average temperatures have exceeded 71.6 F (22 C), with little or no ice at the poles. ...

But humans evolved during the coldest epoch of the Phanerozoic, when global average temperatures were as low as 51.8 F (11 C).

Without rapid action to curb greenhouse gas emissions, scientists say, global temperatures could reach nearly 62.6 F (17 C) by the end of the century — a level not seen in the timeline since the * Miocene epoch, more than 5 million years ago.

 

 

Inbreeding is much more prevalent today, especially in Asia, North Africa, isolated and island nations, than it was in the prehistoric world

From the study:

... we analyze 1785 ancient individuals from the last 45,000 years, a substantial fraction of the published global human aDNA record. ...

... we find that matings among first-cousins or closer relatives, though widely practiced today in numerous societies, are generally infrequently observed in aDNA data. ...

In contrast to the high abundance of long ROH typical of close kin unions in the present-day individuals, long ROH was uncommon in the ancient individuals, including up to the Middle Ages. Additional data from these regions and others with high levels of long ROH today, such as North Africa as well as Central, South, and West Asia, will help resolve with more precision the origin and spread of these well-studied kinship-based mating systems. Overall, our results show how an ROH-based method can be used to inform understanding of shifts in cultural marriage/mating practices. 

From the story: 

... a new genetic study finds only three percent of prehistoric people were the offspring of cousins. For comparison, researchers say that number is actually ten percent today. 

 

 

Meanwhile my basic thesis is that this C19 epidemic continues to spread because 62% of men and 40% of women don't wash after using the loo

The data come from the largest study ever done on hand-washing years ago. You will find similar results in other smaller studies.

Do YOU always wash your hands after going to the loo? 62% of men and 40% of women admit they don't bother 

So that's roughly 51% of the population walking around NOT doing the most basic thing they should be doing under normal circumstances.

That agrees remarkably well with the Nature study on mask-wearing, which found that there is only 49% compliance.

Modeling COVID-19 scenarios for the United States: 

"the national average for self-reported mask wearing was 49% as of 21 September 2020"

I'm assuming it's much less than 49% however, because this data is from self-reporting, not observation.

Be that as it may, the main point is that with nearly half of a given population failing on basic hygiene, it's ridiculous to assume that those same people during a pandemic are going to comply with the litany of things which need to be done to stop the spread of the disease. 

You can't get them to wash their hands after using the loo, let alone wear a mask, wear a mask properly, social distance, quarantine themselves when exposed, quarantine themselves when sick, and on and on.

Results have indeed varied from state to state.

Michigan is a great example. We locked down hard at the beginning, closed everything, wore masks, yada yada yada, and suppressed the epidemic quite well until we couldn't stand it anymore. It caught up with us anyway.

And now the UK variant is giving it to us good and hard this spring. 

People gonna people. Virus gonna virus.

Speaking of phony, between 49% of you and 74% self-report mask-wearing compliance

 There's no way in hell that's anywhere close to true with coronavirus cases soaring by 10 million in two months.

You're all lying through your teeth.

If the Christians exaggerate their church contributions by between 51-115%, it's impossible any of this mask-wearing data is reliable anymore than was the polling data for Biden.
