No asteroids needed: ancient mass extinction tied to ozone loss, warming climate

Title says it all. Article gives us an idea of how fragile the balance is between life and death. It won't take much to wipe out what we all have come to take for granted: life on land.

Of course, some may doubt it can happen. But, let's be real. What is to say it can't? If I had to bet, I'd bet against things going on unchanged rather than for it. Change will definitely come. And, when it comes to Climate Change, the more of it we see the worse it gets.
 
Wouldn't a big asteroid burn megatons of ozone?
 
The ozone?? But, but...I got rid of my Right Guard spray back in the 70's.

It'll rain fire too, once the impact debris falls back down from space.

I mean at sufficient levels of energy "burning" isn't really a meaningful term anymore.

I believe the technical term is it would poof ozone.

megatons of ozone? I'd be more worried about all the particulate matter an asteroid that large would throw into the atmosphere....

What I was getting at is that any ancient occurrence of ozone depletion could be the result of asteroids. They needn't be as catastrophic as to leave a crater miles wide to fry, bake, roast, incinerate or denuclify the ozones.

Any asteroid large enough to "fry" enough ozone to be detectable on a planetary scale is also large enough to leave a big ass crater and all sorts of other evidence of its arrival.

(and the particulates from a large-scale impact cause global cooling, rather than warming)

A laughable attempt to retcon your partisan dismissal of evidence.

You don't post *yawn* when you find the results interesting, you liar.

Sigh. There's no climate debate relevance. That's worth a yawn. Otherwise interesting.

Marshall argues that the warming climate drove more powerful summer thunderstorms, which could have injected an ozone-depleting mix of water and salts into the stratosphere.

What utter drivel.

1, If a warming climate can cause massive sudden ozone depletion, why does it not happen every time the cliamte wars?

2, The amount of chemical action in a lightning bolt is intense but not high in actual volume of it. Even if there was a 1,000 fold increase in lightning it would be less effecctive than our production of CFC's etc which have a slight effect on the ozone layer. If the ozone layer was that fragile we would have destroyed it long ago.

Simple bleeding obvious stuff.

I suggest learning a few things. Staring here might not be a bad idea.

Ancient Ice Sheet Loss Shows Antarctica Can Melt Much Faster Than We Thought

The consequences of Antarctica losing her ice skirt could well be catastrophic for the rest of the continent. With around three quarters of the land mass edged by what is in effect a floating barricade, Antarctica is like a big bowl of cold, fresh water delicately poised to crack.

When it does, we'll not only see a rise in ocean levels, but changes in salinity and ocean temperatures that would have profound effects on polar currents, weather, and ecology.

"We now know that the ice is capable of retreating at speeds far higher than what we see today," says Dowdeswell.

"Should climate change continue to weaken the ice shelves in the coming decades, we could see similar rates of retreat, with profound implications for global sea-level rise."

I know you have trouble doing this scientific thinking stuff but in this debate are you just have to.

Sea level rise has noting at all to do with ozone depletion.

You have to try to stay on topic.

lol...way to go. Few have demonstrated so effectively that the point went whoosh overhead.

Eh??

How does melting Antarctic ice cause any ozone depletion??

How do you manage to impersonate a thinking being so well?

Try to think. What do the two articles have in common.

Both over hyped nonesense of doom with utterly obvious reasons why they are not at all possible?

Try to make a point.

When you speak in riddles you just demonstrate that you don't have one.
