The Last Time Oceans Got This Acidic This Fast, 96% of Marine Life Went Extinct

Oh right. If you don't know something, obviously nobody else could possibly know it. Because you're just the smartestest, bestest educated guy in Denierstan.

You said it.

Still waiting for an honest response to the unanswered question: just how is getting a bigger tax refund stealing your liberty?

 

Been a lot of evidence that is is the sun.

Planet has been warming and cooling for 100's of millions of years...without humans....how does you religion explain that??

You are soooooooo brainwashed.

 

Good hypothesis. But wrong. Solar activity does not match the temperature changes we've seen.

AGW does not dispute that climate change happened in the past.

Footprints have been happening for a long time. Well before humans. But if I see a boot print in the mud I'm sure as hell not going to call it a dino track.

 

Which solar activity? There is more than one you know.

 

Doesn't matter. None of them could have caused the 100 years of warming we've seen.

 

It's not folly at all. It's simple and routine. All you have to do is to change timescales.

For example, consider a roulette ball. It rotates around the wheel rim in one direction, while the wheel rotates in the opposite direction. Once the ball leaves the rim, there are randomizing bumps in the conical ramp. Thus incredibly tiny variations in the speed of the ball, spin of the ball, or speed of the wheel will have drastic and unpredictable effects on which slot the ball falls into. It's a classic chaotic system, which is why it's extremely difficult to predict where the ball will fall on any given spin.

But if you change timescales and take the longer view, prediction is routine and easy. There are 38 slots in the wheel (including 0 and 00) so over a large number of spins each slot will receive 1/38 of the total. Over the long haul, the house will win.

That's why it's more difficult to predict weather, which is mostly chaotic, than it is to predict climate, which is mostly linear. It's a matter of scale.

 

Really? Citations, please.

Oh right. Forest fires happened before humans, therefore humans cannot cause forest fires. Brilliant logic from Deneristan.

And yet, you're the one who cannot provide citations to support his assertions, while we're the guys who can. Hmmmmm ...

 

Drop a little sodium bicarb in it. It will be okay. Or maybe not.

 

For many life forms on this planet it is indeed already too late, the extinction of species has been happening at levels not seen in some time for quite awhile and those creatures are not coming back. Climate change will likely increase these numbers in the next 100 yrs. to something universally agreed to be the next large extinction event, some circles already do so:

"BIODIVERSITY

The Earth’s biodiversity — the variation of life at all levels — is the result of 4 billion years of evolution. And now it’s vanishing in the blink of an eye. Under relentless pressure from exploding human populations, animal and plant species are going extinct at 100 to 1,000 times the natural rate. The diversity of life that sustains both ecological systems and human cultures around the world is collapsing."

In my opinion, we are witnessing the 6th mass extinction event right now.

 

I don't think many scientists would dispute that.

 

Not many scientists would even say that. The idea is that we are in the 'brink' of a mass extinction event based on faulty models. None have been witnessed yet.

 

Good to know your science denial extends past global warming. http://www.sciencemag.org/content/345/6195/401

Do you think evolution is wrong too?

 

The loss is driven primarily by loss of habitat and global climate disruption. The list of extinctions since 1500 include hunting to extinction and loss of habitat. I didn’t find any losses due to global climate disruption. The report seems to be very similar to a report in 2010 on vertebrate extinctions. In both cases, the conclusions were based on literature reviews and endangered species lists and estimates. Extinctions are still quite rare. I’ve missed the global climate disruption, so shat must be based on predictions of mass extinctions from predictions of climate change. At least they aren’t claiming extinction of unknown species that now we will never know.

Is it that you do not research the things you comment on?.....or is it that you just feel the need to deny all scientific data that hints at climate issues?

It has become exceedingly difficult to deny that something is going on with our planet, and hiding from it does not paint you in a very good light.

 

Provide the full paper, explain it to us all.

If you mean it is exceedingly difficult to deny something unproven and full of alarmist memes?

 

Lets try this.....I cannot provide a study or document that proves women enjoy sex. Instead I note multiple sources and extensive experience that combined with common sense allow me to accept it as a truth. I personally do not much care what you think about the changing climate conditions as there is literally nothing we can do regardless of the reality. As far as the topic we were ACTUALLY discussing...it is painfully obvious that species are going extinct daily on this planet, were you to actually spend ten minutes on the internet looking, you would find all the data you could hope for.

 

So, now you are trying to equate a chaotic climate with sex? LOL Nothing like more logical fallacies to prove a point. BTW, there are plenty of extinct species before man ever arrived. It happens.

 

I am so done with you....have fun stormin' the castle.

 

I know, science is really hard for some people so they must rely on alarmism to get them through the day.

 

Yeah, it's a real shame watching our politicians repeating the mistakes the Permian politicians made

 

You have to wonder about people who want to compare alleged AGW with ancient extinction events, since it's pretty clear that it didn't take any artificial pollution of the environment due to machines, industry, burning of fuels, etc. by any particular species to cause those events. Nature screwed itself up.

Plus, it's only by virtue of each and every mass extinction event that ever occurred that human beings are even here today.

 

I am sorry but I am someone who would rather learn from history. That IS what intelligent life does We know nature has had previous changes in climate and previous mass extinctions - each though had a reason. The current change is caused by man polluting the atmosphere and removing forests

 

You mean history predicted things that never came to pass?

 

I was following you until....

... the last sentence. That hasn't been demonstrated scientifically. It can't be, in fact, since we're talking about the future, trying to predict what global climate is going to do without understanding it well enough to be making such predictions.

We, including the best experts in the relevant fields, simply cannot be certain about what exactly was behind past mass extinction events, though the theories have so far included cataclysmic events such as massive volcanic eruptions and collisions with large space objects. Our impact on the environment is minuscule next to such events, and it is also different in character.

I will grant that if in fact we are causing the oceans to grow more acidic (this cannot be verified, however), then I would agree that we're definitely causing a problem that could lead us to a catastrophe of the mass extinction kind. But that is a big "if" we face.. And I think it's very irresponsible for people to be carrying on like Chicken Little about the greenhouse roof falling on our heads, pointing at every powerful storm or record-setting recorded temperature and assuming that it's evidence of their belief. That's why scientists actually tend to be very conservative about assuming they know or understand anything; time and again people have been made to look foolish when they've been proven wrong about something they were adamant about previously due to incomplete data and a possible personal bias.

Also, do you know how annoying it gets listening to people bleat about global warming while winter in my neck of the woods refuses to let go and let me have spring at last?? And that's for the second year in a row now.
