Global Warming not Collisions caused mass extinction on Earth
Latest findings might change the way we see history as scientists have made a startling discovery. New evidence has indicated that the biggest mass extinction in the history of the Earth some millions of years ago happened due to global warming. It has been until now blamed on some comet or asteroid hitting the earth wiping out entire continents worth of life.
In an online version of a scientific paper, researchers headed by University of Washington scientist Peter Ward claimed that their research could not find any evidence of collision on the planet which caused the so called ‘great dying’ 250 million years ago. They blame the mass extinction on atmospheric warming caused due to greenhouse gases triggered by erupting volcanoes.
This incident might have caused the biggest destruction in the history of our planet as research shows that 90% of all marine life and nearly three-quarters of land-based plant and animal life disappeared. The paper said: “The marine extinction and the land extinction appear to be simultaneous, based on the geochemical evidence we found. Animals and plants, both on land and in the sea, were dying at the same time, and from the same causes — too much heat and too little oxygen.â€
The researchers collected evidence over a time-period of 7 years during which they gathered 126 reptiles/amphibian skulls from a 1,000 feet thick section of exposed Karoo sediment deposit from the time of the extinction.

Quote:
It’s bad enough when, every few million years, an asteroid rocks our planet. It’s worse if the impact triggers regional or global volcanic activity, which is not only hazardous to nearby plants and animals but can choke Earth’s atmosphere with deadly gases for months or years.
But there’s also a possible bright side, like the birth of nice places like Hawaii.
For more than three decades, scientists have explored the question of whether an asteroid impact could cause significant volcanic eruptions, hot spots that spring up out of nowhere and create new landforms or rearrange old ones. The process might have given birth to the Hawaiian islands, for example. The idea of linking space rocks and lava goes back to at least the 1960s, and in recent months the debate has heated up like a volcano ready to erupt.

…Off w/Their Heads!!!
very interesting article…is global warning likely to cause another mass extinction a second time? And you’re saying that greenhouse gasses were triggered by volcanic eruptions, yet currently the threat is that we are damaging the atmosphere…If global warming were to cause another extinction is it because natural causes make it inevitable, or will it happen because of us?
Lets see … most of life on earth destroyed by a sudden, simultaneous flood. Where have I read that scenario before?
Where does this say anything about a simultaneous flood? It reads “too much heat and too little oxygen.” Did you even read the article?
Right on, Jesus! You tell those fundies how it really is, brother!
It is nice to get comments from viewers of the web.However.In this case we have to look at the facts available to us. When events happen over 250 million years ago we must rely on the expertise of the geotechnical community as we do not have a time machine to go back and see for ourselves. We as the uninformed or uneducated must defer the those who at least have some skills attained through training to provide us with the best possible educated hypothesis. I conclude that it would be comforting to finally put this argument to rest as to relieve those would be couch experts of the strain of it all. Perception is certainly reality for most.
hey t
â??The marine extinction and the land extinction appear to be simultaneous, based on the geochemical evidence we found. Animals and plants, both on land and in the sea, were dying at the same time, and from the same causes â?? too much heat and too little oxygen.â??
Hmmmm….Sounds to me like evolutionary science “THEORY” just can’t make up it’s mind (again and again and again). From Ice age to Global warming? Come on….How can you go from one extreme to the TOTAL opposite?!!! The answer is in the previous quote. Mass extinction, all at once, globally! It’s a FLOOD!!!
â?¢ The current population of earth (5.5 billion souls) could easily be generated from eight people (survivors of the Flood) in less than 4,000 years.
â?¢ The oldest living coral reef is less than 4,200 years old.
â?¢ The oldest living tree in the world is about 4,300 years old.
Read the bible!!! The answer (the TRUTH) is in black and white!
Stumbled across your “fascinating” discussion after clicking on a Google News link. The latest “theories” by the scientific community about what happened oh, say, a couple of hundered million years ago, is just that - a theory! The reality is that they’ll have some other explanation next year, that will change again the year after… and so on. Why? Because they really don’t know.
Let’s all say this together… Galileo… Christopher Columbus… we get so wrapped up in our egos and what we “think” we know. We never stop to question whether or not the popular theories of the day are even right.
But I ramble… carry on with your interesting nerdy existences…

drew! Carefull of This Liberal Democrat, Agenda-tized, “Half-Ass” Science!
Who Knows? They May Be Trying To “Get Funded”!
Seems this “study” comes to their conclusion because they couldn’t find any evidence of a planetary collision 250 million years ago. This is plain ignorance and has all the red flags of man-made global warming hysteria. Makes me wonder what reasoning they have for the global warming taking place on Mars.
It makes sense that we could have experienced mass extinctions from volcanic activity and global warming, but that would also lead us to believe that the earth can/will/did repair its own atmosphere over the course of time (otherwise we wouldn’t be here) and we shouldn’t put so much effort and money into protecting it now (e.p.a). So, find some cfc containing products, light a joint and have a party, because there is nothing we can do to prevent “the end of the world”.. except maybe pray to god, and we saw how far that got the Tsunami Victims. Not to sound cold, but fundamental Islamic’s, like the inhabitants of Thailand, are far more religious and dedicated to their beliefs than the average modern American, and they died just the same as everyone else. Enjoy your life, because you only get one shot, and then you rot in a box like everyone else.

Does it realy matter in the big picture. the universe is un folding ever changing a star is born every split of a sceond a star dies every split of a second. Our actual history is now. We fret in fear as we rush through space on a revolving speck of dust.What could happen to us next? Anything and Everything are resonable quesses from me
May l suggest we put our intilligence and resources to task of things we really need to care aboutand what we actually can do.
Like protect, nuture and care for everything that brings life to the spinning speck of dust we call earth.
well.. when life on earth is dependent not just on earth but Mainly on SUN and balance in this universe.. how can we blame EARTH for mass extinction . . earth itself i dont think is capable of wiping of its entire bilogical life.. we know how sun emits strong radiation in pulses can it be a reason.. c’se to destroy life on land and water.. i see the culprit is some sort of radiation.. ,we also need to Understand the SUN in depth .. well.. but finally i dont believe volcanos can trigger such extinction .. not even meteorite( i never accepted the meteorite theory which caused death of dinosaurs too)
The second I saw this headline, I wondered how long it would take the agents of the Diminishment to swoop in and denounce it as ‘empirical, scientific, objective, secular, humanist, rational’, the worst that an educated and knowledgable civilization could produce.
It did not take long, I see. :)
“…geotechnical community…” …Peter?
“geopolitical community” …Is More Like It!
You know your making progress against those who are on the wrong side of history when you get a ‘GW Bush is full of **it’ comment in a forum like this.
Not at all surprising!
WE are already seeing a large number of extinction caused by us through habitat destruction. Since it happens slowly in terms of our life it doesnt seem to strike us.
In geological terms the history of the human species is like an instant!

Well well. It is always interesting to me to see that the psedo-religious are out surfing the net in search of science to bash. Please please you zealots just stay the heck in whatever hole you crawl out of. Asking questions, proposing theories (some of them wrong and some of them right) are what have allowed humanity to prosper. Not belief in some all seeing judgemental being up in the clouds. If you don’t like science then talk of all of your clothes stop taking any medicine quit your jobs sell all of you belongings and sit in a room and pray all day. Then your god can provide for you. One more thing before you take the time to bash science for its “theories” remember scientific theories are based on evidence and experimentation. Your beliefs are based on what some guy tells you in a building every Sunday and what you read in a book that has been reedited and retranslated a hundred times over. Do you remember the game telephone? Think about it.
ok.
breathe deeply.
there are irrational thinkers amongst us
who do not understand how science works,
& that in science, evidence is everything.
Evidence is everything.
Word: your assertion, conjecture, argument
is worth less without evidence.
E.g., Grog & Grogette were walking
on the Serengeti 70k yrs ago.
From a distant hillside,
grogette notices that large cats
are stalking Grog.
Grogette forms a hypothesis
(an empirically *testible* answer to a question):
the large cats are not playful kittens & will eat grog.
The hypothesis is testable.
Evidence: the lions pounced on Grog
& ripped out his internal organs,
then feasted on his loins.
Tens of thousands of years later,
Grogette’s great, great,great…great
grandchildren became scientists
who insist that, for any hypothesis,
evidence is everything.
Evidence is everything.
“…records show that for the past 50 years or so, the warming trend has sped up — due, researchers said, to the atmospheric burden of greenhouse gases produced by everything industrial, from power plants burning fossil fuels to gas-guzzling cars — and the effects are clear.
“We were stunned by the similarities between the observations that have been recorded at sea worldwide and the models that climatologists made,” said Tim Barnett of the University of California’s Scripps Institution of Oceanography. “The debate is over, at least for rational people. And for those who insist that the uncertainties remain too great, their argument is no longer tenable. We’ve nailed it.”

Climatologist Wally Broeker once said,
“the climate system is a capricious beast,
& we are poking at it with a sharp stick.”

Any questions?
Thank you Ken Z
Please, all you religous people that think its fun to bash all scientific theories and the true practices. Go Home!
