"Global Warming, Not Asteroids Caused Planet's Mass Extinction Events" - Leading Climate-Change Experts

“If you look at the fossil record, it is just littered with dead bodies from past catastrophes,” observes University of Washington paleontologist Peter Ward. Ward says that only one extinction in Earth’s past was caused by an asteroid impact – the event 65 million years ago that ended the age of the dinosaurs. All the rest, he claims, were caused by global warming.

Ward's Under a Green Sky explores extinctions in Earth’s past and predicts extinctions to come in the future.

Ward demonstrates that the ancient past is not just of academic concern. Everyone has heard about how an

I looked around and could not find this so I thought I would post the article.

It is and interesting idea and anything from Climate change experts deserves some ideas about it. I would really like to know what they think about the other asteroid impacts...Interesting article none the less and I think this would be the best place to discuss this.

Any thoughts?

Scaremongering. Nothing else.

Next they gonna say global warming caused pedophilia and raped your mother.

The KT boundary (and there's some right out of town) is kinda hard to ignore as an impact event Centered in the Gulf of Mexico North of the Yucatan, and then there's the Ice cores!

if global warming caused the extinction of the dinosaurs and all the other "mass extinctions" then perhaps it proves to be a natural accuring event and could hardly influenced by man spending extra billions of dollars on saving energy.


in this respect i refuse to spend one red cent on the "green" crud that is flying round.

Well, "technically" one caused the most massive extinction event at the Permian-Triassic boundary. However, this was in turn caused by immense tectonic activity releasing vast quantities of basaltic magma as well as huge amounts of gasses into the atmosphere. To understand how much magma, the stat i heard is that it could cover the Earth's landmasses in up to 3 feet of lava. The gasses would have created a super greenhouse effect for sure, but what caused the great extinction was the de-oxidization of the oceans (where almost all life was located at the time).

The reason for this intense volcanic event? Well around that time, the super-continent Pangaea was breaking apart at the end of the 400million year super-continent cycle into Eurasia and Gondwana. For a similar event, take a look at the Great Rift Valley in eastern Africa, where the same sort of thing is occurring at a smaller scale.

So overpopulation led to massive amounts of dinosaur farting which in turn caused global warming...correct?

what will they come up with next. as you can see they are trying very hard to make us buy into this BS, they've even resort to fear. this is pathetic, why do we allow people like this to walk the earth. anything to make a few bucks, even lie to the world.

Anything but the truth from these guys "So called top Professors"
1. Up to about the 80's the Dinosaurs were beleived to have just died and slowly burried over time Billions of years ago.

2 Then we had the "They all got a disease therory" I think that was Jack Horner's idea

3. Then the dreaded Asteroid, which is just as stupid as the first two.

4 Now Global Warming.

Next therorys will be POLE SHIFT
ALIEN INTERVENTION
NIbirui (spell check)
All these lame therorys can get funding but you mention the "Flood" as in Noahs flood and you won't get a dime. All about the money. Plus if leading figures in the scientific circles addmitted this , that would be proof of the Bible story and we just can't have that.

The source doesn't discount that the KT extinction event was caused by an asteroid, just that those prior were not, as far as they know.

Also, it is to be understood, that the article does not state the reasons for any greenhouse effects/climate shifts, just that they were responsible overall for extinction events.

Haven't read the article - was impressed with your response - one of the greatest causes of long term C02 levels was India moving across the indian ocean - this slow moving event through up great quantities of carbon - the eventual impact into Eurasia as well - we have been recovering ever since (diminishing co2 as it is re-sequestered as it were).

Global warming has become one of "those" issues where people just jump to parrot "their" opinions without even merely reading the OP.

I personally discredit an extinction as a "doom" event in which species cease to exist. Obviously, species old as life itself still exist, they've just changed. Dinosaurs exist too, they're everywhere and are very successful as modern birds - beings we always admired and even considered godly or divine. Those that remained status quo were exterminated.

The worst thing that has ever hit our planet is the Permian extinction. It is believed that the extinction was caused by severe oxygen deficiency in ocean, called anoxic event. This extinction has almost reduced life back to microbes. That in turn was caused by, guess what, global warming. And no, farts didn't cause global warming, it was something massive, sudden and unpredictable. You can read about anoxic event if you want to deny ignorance!

Now is current global warming our fault? Maybe not, but we do everything we can to contribute instead of learning. Increased tectonic and volcanic activity always announce a massive release of "bad gasses" which may be a trigger for an event which we won't be able to fix, because "it's not our fault". The consequence of Permian extinction is almost complete eradication of life, not just human, a restart of life on earth. I'm sure though the elite will continue their forsaken existence in one form or another .

To conclude, global warming is already believed to cause the worst extinction known to us.

I don't see how this is scaremongering in the least. I don't buy into the BS man-global scam but I do understand the idea of natural cycles. It's not scaremongering it's just common sense and fact.

The earth will warm. Many life forms will continue to go extinct. But the catch is that many more will rise from the ashes to continue the cycle of life.

It doesn't mean that MAN is doomed. Well, eventually we probably are but that's just the natural process.

I mean, is it 'scaremongering' to say that the earth will eventually be destroyed by the very sun that gives it life? Well, it's true.

Excellent article, find. S&F

Your source article is easy to read and exceptionally informative. I hope the posters on this thread take the time to at least scan it.


Here's my favorite bit:

"...we are on a planet that has violent convulsions, and ...we humans are playing with nature in such a way that we could recreate what were some really awful times in earth's history, ...we really tinker with the earth's atmosphere at our peril."

Thanks again.

Agreed. The article is nothing more than an attempt to associate the current global warming debate with past extinction events. He's basically saying 'See? This is what's going to happen if you don't listen to us and hand over the cash.'

Of course, there's a gaping hole in the argument big enough to sail a battleship through. All of those past events, regardless of cause, were natural occurrences. Given this fact, its logical to believe that the current one could easily be a natural event as well. As such, his argument is largely self-defeating.

I wonder how much private interest went to pay for the article and the writer of it.

See people forget that money talks and BS walk as the law of the land.

In America education is down the crapper, then we got religion to tells us that dinosaurs either didn't not exist or they cohabited with man, so it kind of makes the entire article look like another attempt to take history and twisted for global agendas interest.

Hey marg,

I'm really worried that people in the US aren't separating the 2 issues: 1. Climate change/global warming; and 2. What to do about it, if anything.

Also, most deniers contradict themselves, saying:
1. The climate is not changing and seas are not rising; and
2. The changing climate and rising seas are all part of a natural cycle.
[Either ain't happenin' or it is and it's part of a totally natural cycle - but not both.]

This whole thing is a huge mess, no doubt about it. ...Seems to me a few of the climate guys tried to play the same games the Big Boyz play - but they weren't very good at it and got caught. ...Doesn't mean it's ALL wrong. Just means we have to check everything. Nothing new there.

Well yes of course the ever-changing climate has had an effect on the survival and evolution of life, it would be foolish to think otherwise. I think these guys are overplaying it but one important thing we can gather from this:

Human industry wasn't around for those extinction events. Those who politicized Global Warming tend to hurl abuse at us dirty filthy humans for our industry and leave out factors like the sun, and the CO2 put out by every other organism on the planet. But now, thanks to these ancient events, we can see that millions upon millions of years of organisms putting out CO2 did nothing to stop ice ages and nothing to end them... In other words we have very little control over the climate and even if we stop polluting (which we should, cause I love this planet and don't think we should be hurting it) it might not stop the climate from changing...

Of course we humans have survived ice ages before, we're one of the most flexible species on the planet in that regard... Bring it on

I believe climate is changing, but not with the urgency that lobbyist paying out whores in congress to pass climate bills for taxes and profits wants us to believe.

When I look behind the ones pushing the whole climate bills agenda I realized that is nothing but money signs for profits at the expenses of tax payer in the nation.

Still history plays a big role of how our earth is ever changing, we are nothing but another species in this planet no different that any other now extinct species before us long gone, religion plays a big role claiming that we are special.

The earth will do what earth do and is nothing that lobbyist, climate bills or any or us can do about it.

The same way that those species before us were not able to stop from becoming extinct.

We are do for a major climate change and is not global warming, but earth cooling.

It's just that for big climate change profiteers warming is easier to sell and be blamed on human fault.
