Yeah, there's been a shitload of mass extinctions. Just starting to get into this stuff.

I find the whole Carboniferous Tree thing, with Lignite in those older trees having no decomposing bacteria to digest them, becoming the main source of coal, interesting. Trees just fell on top of trees which fell on tops of trees which hardly decayed, for millions and millions of years. No bugs or bacteria to break down the lignite.

Also learned that Coal has literally nothing to do with Diamonds, at all. Diamonds are found in igneous rock called Kimberlite, Coal is compressed organic matter. Totally different strata and processes.

Also cool, photosynthesis by (the ancestor of modern) cyanobacteria caused a great extinction of anaerobic bacteria, the first lifeforms, by emitting to much Oxygen. Oxygen is a killer chemical!

Finally, the Earth's temperature has fluctuated wildly, even in the total absence of primates, much less humans, over and over again. Sometimes slowly, sometimes quickly and wildly. There is no "optimum temperature or CO2 ppm" on this Planet; it constantly cycles.

There is no optimum temperature or CO2 ppm" FOR this Planet;
There is an optimum temperature or CO2 ppm" FOR the apes on its surface and the civilization they developed in the past 10,000 yrs that supports now 7 billions of them;

And caused the temperature to plummet and froze the entire planet to a snowball.

It oxidizes stuff!

I get a kick out of shows with astro-biological predictions of what some life might be like on some other planet with 'harsh' conditions. They might feel the same way learning about our planet.

I don't recall if there was much oxygen yet during the carboniferous however if there wasn't there probably weren't trees being oxidized (burned) by oxygen (the wood carbon reduces the oxygen) either!

What is optimumum temp for human habitation?

anonymous says

Why don't you do us all a favor and let us know what it is,

Humans can survive in a large range of climates.

They do.

The alarmists want us to believe that the temp has remained constant throughout history and now, since the hockey stick did not happen, a couple of degrees is catastrophic.

The "ideal temp" question just exposes the fraud of the alarmists.

Please share with us what that temperature actually is.

Does yesterday's earthquake in Delaware count? I felt it.

That Doobie shaped Chunk of a Continent that sailed through our solar system from the Top.
Could have been a planetary fragment from a violent planet collision. It could have been a flagship for many more.
One of those things were to hit our planet there wouldn't be much atmospheric entry friction to burn it up. It will pierce right through it like a bullet.

anonymous says

When will the Earth try to kill us again?

What's the rush. Enjoy life.

anonymous says

It's a pointless question posed by Onvacation

What is the point of global warming climate change if the temp and sea level are rising very little?

Alarmists have no answer.

Seriously what is the point of "climate change" beyond scaring children, taxing their parents, and controlling the population?

8 billion people are NOT going to stop exhaling co2 over a propaganda campaign.

Let's move beyond this scam and solve real problems.

anonymous says

t's certainly good to know higher education or even high school wasn't wasted time for you

Are you going to address my points or just attack my person?

When will people stop being paranoia?

Not sure there's an optimum temp or CO2 for primates, so long as the average temp isn't in excess of 100F and the CO2 isn't to the point it interferes with respiration, which would have to be measured in double digit percentages of the whole atmosphere, not in ppm.

Update: Just looked this up. So long as there's enough Oxygen, there really isn't a fatal level of CO2.

Update 2: Another source says 50,000ppm starts being dangerous for animals. We've got a looong way to go to 50,000ppm. That would mean CO2 goes from 0.04% to 5%.

And of course the best one, from 1978:
www.youtube.com/embed/L_861us8D9M

"Only in the last 10,000 years has Earth enjoyed continuing warmth..."
Dr Gifford Miller, Geologist and Glaciologist, University of Colorado: "One of the questions I'm most frequently asked is, when will all this warmth end. I tell them it ended 3000 years ago, here on Baffin Island."

Yeah, tenured professors looking back from 1978 didn't see ever increasing warmth, but ever increasing cold, when looking back.

anonymous says

their is no ideal temperature

That is the point.

And that temp is NOT rising rapidly. It is hardly rising at all.

CAGW is a scam. That's all I'm sayin'.

anonymous says

That 1.5 degree rise over the last 130 years is very dramatic in the big scheme of things.

So what about the hockey sticking of temp and sea level? Can you tell us why that has not happened?
And what about the arctic ice? If global warming were true wouldn't we have less ice every year instead of the trend of more ice over the last five years?

I ask these questions to expose the fraud of CAGW.

The alarmists predicted a massive spike in temp and sea level rise. When global warming did not happen as predicted the alarmists changed the name to climate change and said

"And another two degrees by the end of this century will be the end of hunanity if we don't give up producing co2."

Sorry you have bought into the propaganda.
