Global warming extinction prediction: many were made, none have happened

I gotta find my tinfoil hat.

 

Ah, to reflect the heat back into space.

Good idea. If you want to save the planet, wear your foil hat.

 

You got my point: Those buying into all hyped fear of global warming/climate change are wearing a tin foil hat that was tailor made to be two sizes too small… thus squeaky their brains out of their ears.

 

This happened at a time when humans were not yet emitting large amounts of exhaust gases from their combustion engines.

Time has changed, bro. Now we're confronted with a problem that didn't exist before industrialization.

 

And the Permian extinction did like wise and that atmosphere had a far higher percent of CO2 which it maintained until the later days of the cretaceous and the first deciduous trees and other flowering plants changed all that. Note for what it is worth the giant space rock that killed the dinosaurs appears to have killed a population that was already under a great deal of stress as those previously mention flowering plants slowly leached CO2 out of the atmosphere.

 

So what?

We are confronted with lots of problems that didn't exist before industrialization -- like widespread obesity. CO2 just isn't one of them.

 

Our planet needs CO2. The problem arises from oversaturation.

The greenhouse effect usually helps creating comfortable temperatures for life on earth. But with our unnatural CO2 emissions we're increasing it too much, thus killing all life on earth.

You can stop obesity by eating less and you can stop climate change by producing less CO2. The problem here is: you can't force all of humanity to act rational. The stupid ones will decide our downfall.

 

Killing all life on earth? You do realize temperature related human mortality is decreasing with warming, right? You do realize we are so adaptable we can increase crop yields up to 12% by using our big brains to leverage the positive aspects of change?

The current temps of this planet are so uncomfortable that 10 times more people die of temperatures below optimal as die from temps above optimal.

Yes, all the above are the conclusions of peer reviewed studies in reputable journals of science. Your opinion is not. Don’t be scared. Warming will decrease your chances of dying, contrary to popular belief.

 

Sorry but its more complicated than that.

 

LOL. Nope. I presented the facts. That’s pretty uncomplicated.

When you start getting into the plant and animal genetics and physiology that are responsible for the facts I listed it gets a little more complex.

For example, the genetic variations that allow us to choose corm hybrids based not only on heat units to dry down, but also on heat units to pollination and maturity and thus taking full advantage of longer growing seasons and more precipitation isn’t simple for folks without knowledge of the subject to understand.

But the fact remains. Warmer climate reduces temperature related human mortality. And allows for production of more food. So MANY species are greatly benefitted, contrary to the claim I responded to.

Just because you haven’t been told these facts doesn’t make them not true. You have been misled. Sad.

 

Life did fine when CO2 was an order of magnitude higher, and there is no credible empirical evidence -- none -- that it is harmful in any plausible atmospheric concentration.

No, that's just absurd nonscience with no basis in fact. The best empirical evidence is that the increase in CO2 since people began widespread use of fossil fuels has been of substantial benefit to plants, and thus to all life on earth.

Your own, anyway...

No you can't. Climate has always changed whether anyone used any fossil fuels or not, and producing less CO2 will not have any measurable effect on climate.

The stupid ones would be the ones who think using fossil fuels will cause significant warming of the earth's surface, let alone kill all life on earth.

 

The history is full of sudden extinction events. Getting hit by a celestial body is the primary cause of these events. And yes, you're correct, adaptation to an event like those is very hard on the existing ecosystems around the globe. The difference is that the runaway CO2 stuff is snake oil. We need to treat it as such.

 

Which can cause problems.

 

Oh. You are one of the folks that disapproves of decreasing human mortality! It’s pretty common I’ve found.

Yes, climate change presents some problems. No more than stasis and far less than cooling. You may not be aware of this but there were problems caused by climate before we figured out a use for fossil fuels!

You are learning a lot!

 

Nope, its the other species I'm worried about.

 

Which? Why? You want to stop the evolutionary process NOW?

 

Except they don't make predictions they just point out that the catastrophe shills have never been close to being right.

 

A we have no idea how many species there even are or how many have already died out. There are even arguments about what constitutes a species. B. Is A a unique species in its own right or just a color variant of another quite closely related species..

True. We can flesh out the deception these nutters have been fed with a little math.


We are told there are around 10 million species in existence today. Around 2 million have been identified and catalogued. That’s 20% of all species identified.

We are told approximately 1,100 species go extinct each year (range 200-2000). Some reports claim 800 extinctions over the last 400 years. One report claims 160:extinctions over the last decade, but admits many of those species disappeared long before they were declared extinct in the last decade.

So, if there are really 1100 extinctions annually we would expect somewhere in the vicinity of 220 identified species to be lost annually. But we can only document at most 2-16 per year. Some of the above wild ass guesses could be true. But not all of them. The math doesn’t come close to adding up.

Add in the fact only around 300,000 fossil species have been identified out of an estimated 5 billion actual projected extinct species from a 3 BILLION YEAR period we use to calculate background extinction rates and the math gets even fuzzier.

Am I saying there are no extinctions? Nope. I’m saying we have NO IDEA what the extinction rate REALLY is. If we don’t know with ANY certainty what the rate is at present, how much certainty can there be about the future.

Not much!

The most effective way humans cause extinction? Globalization. Trade and travel. Introduction of invasive species and pathogens. We have been helping a fungus kill a lot of amphibians lately. Anthropogenic warming is far down the list of things people do to eradicate species.

 

Warmer climate will probably enable disease spreading and poisonous species to significantly increase in number and range.

 

When? If you aren’t concerned with human mortality why do poisonous species matter? You worried poisonous spiders will hasten the extinction of flies? LOL

You worried about warmer springs causing less pneumonia in calves? I get the feeling you have no idea what you are talking about.

 

It's true that because isolation drives speciation, our extraordinarily effective intercontinental transportation systems have resulted in the extinction of many species. But that has very little to do with CO2. We are also losing species to habitat destruction and commercial over-extraction of wild stocks; but those processes also have very little to do with CO2.

One can understand concern about loss of commercially valuable species, but it is less clear why anyone would care about loss of biodiversity per se. That's just how evolution works.

 

Yes because everyone knows that pathogens and poisonous critters are way more adaptable than anything else...


not.

 

I heard racism is caused by global warming.

Or was that global warming is caused by racism?
