Climate deniers don't deny climate change any more

Why would there be significant temperature differences so close together?

 

So what caused the increased coral bleaching if it's not from increased ocean temperatures? Or as a climate change denier are you just grasping at straws too?

 

What do people north of Cairns have to do with anything? We are taking about agricultural land use here. We don’t make sugar out of humans and we aren’t killing trees to build apartments. LOL.

Are you referring to the outer reef?

Do you have evidence nutrient just disappears at a certain distance offshore?

Don’t know.

A lot higher than 100 years ago.

Then there is the addition of runoff nutrients detailed above. Exact concentration I’m not interested in looking up.

 

So what scientific evidence do you have to support your hypothesis that the coral bleaching is not caused by increasing ocean temperatures and is caused by nitrate levels?
And what evidence do you have that nitrate levels have suddenly increased within the last 20 years 250 km off the coast?

 

“Bleaching “ reports have increased because of the development of marine science. More interest in science is responsible for more reports.

And…the further north the warmer the water. Just how it works in the southern hemisphere….




Why would you resort to calling me a climate change denier? I’m all over PF explaining numerous anthropogenic warming pathways—probably a bunch you’ve never heard of.

I challenge you to quote me using the PF quote function denying climate change! Go…

Oh, that’s right…you can’t because no such quote exists. You are posting more fallacies. And I’m waiting for you to answer the questions I’ve asked…

 

That's your issue not mine, and I have no reason whatsover not to believe that the recent coral bleaching, and melting of the ice caps and glaciers etc isn't caused by global warming and increasing ocean temperatures, and why our weather bureau has added an extra colour on it's temperature maps for shade temperatures above 45 degrees.

 

It’s been supplied to you. Bleaching is caused by a combination of nitrates, lack of natural fertilization by sea birds, temperature, etc. It’s not a single cause.

Nutrient out of balance allows bleaching at lower temps. It slows recovery after bleaching. It’s all in the studies and pull quotes I’ve provided. You can accept evidence produced through application of the scientific method I’ve presented or not. Up to you.

What evidence do you have that temperature has increased more than nutrient and sediment over time? Are you really unaware of the destruction nutrient and sediment and lack of natural sea bird populations have on coral? Why deny the science?

 

IOW the recent coral bleaching is caused by increasing ocean temperatures and not by ocean nitrate levels.

 

IOW the recent coral bleaching is caused by increasing ocean temperatures and not by ocean nitrate levels.

 

No. It’s caused by both. Often in combination. Not my opinion. The conclusions of the studies I’ve presented.

My point is you can quickly address nutrient runoff. You can’t quickly lower ocean temps. You care only about solutions that are impractical and deny the science behind practical fast solutions.

What’s to gain by denying a lot of the destruction of coral is from nutrient runoff, sediment, overfishing etc.?

 

That is the issue. Bleaching has always taken place for multiple reasons. Bleaching occurs and then the coral grows back. Over and over again. There is greater visibility in the last ~ 150 years because of the advancement of marine biology and consequent observation increases.

@Mitty,

Please substantiate your allegation I’m a climate change denier. Your last remnants of shredded credibility rely on you substantiating your allegation.

 

I see no evidence to support your claim that ocean nitrate levels have increased 250 km off the coast in the last 20 years and are the major cause of coral bleaching

 

None of that changes the fact that increasing ocean temperatures are the main cause of the recent coral bleachings, and I have no reason to believe otherwise.

 

I don’t make “claims”. I just educate folks on what’s out there in the big world of science.

Evidence has been presented in the form of peer reviewed research. Your opinions are irrelevant. Your denial of evidence produced through application of the scientific method is noted.

Your lack of knowledge on a subject doesn’t make others who have more knowledge “climate change deniers”.

 

No one can control what you choose to believe. Faith based narratives are impervious to factual information.

 

Even though you are the world's expert on coral bleaching, you have no evidence to support your claim that the ocean nitrate levels caused the recent coral bleaching 250 km off the coast and north of Cairns, and not increased ocean temperatures there.

 

I’m no expert. Just posting evidence produced through application of the scientific method. Again, I’ve made no claim. Just presented evidence temperature is only one part of the equation. I just base my posts on research conducted by marine biologists and climatologists instead of Wikipedia.

And corrected a lot of your misconceptions along the way. You don’t have to be butt-hurt because I know water temperatures are higher in the northern regions of the reef. You don’t have to reject peer reviewed studies on how nutrient levels and ratios affect bleaching all over the planet (not just the GBR) just because you’ve been misled on threats to coral and coral symbionts. You don’t have to reject science just because you got called out for making false accusations about other PF members.

Perhaps you could pinpoint what part of the GBR you are referring to with your 250 km figure. Remember, bleaching isn’t caused by single factors. Go ahead and point out the part of the GBR you are referring to and we will explore the evidence.

Oh, waiting for your answer to when we will see cooling oceans…. LOL

 

To be completely accurate, it only exists because of "Global Warming". You are aware that it is only around 8,000 years old, right?

I regularly shake my head at how people think that so many things they see are permanent and have always been there. Like the San Francisco Bay. The first humans in the area never saw that because it did not exist yet. And the coast was still 20 miles to the west.

 

Do you have any evidence this is any different from the previous time frame between glaciation events?

Or are you one that believes the planet should be static, and never change from what it is like today? Or at some previous mystical prior time point that nobody can ever seem to agree on.

 

It will disappear, and trying to pretend otherwise is a sure sign of insanity.

Here, to give an idea this is the coastline at the last Glacial Maximum.



When there was obviously no "Barrier Reef", because it was dry land. New Guinea, Australia, and Tasmania were all a single land mass. And we are only about half way through the interglacial ocean rise, so before much longer geologically speaking the barrier reef will die because it will be in water too deep to sustain it. And another barrier reef sill start to form.

This has happened many times, are you saying that for some reason we should not expect it to happen this time?

 

@Mitty,

This may save you some trouble trying to substantiate your claims. Looks like the 2020 event didn’t effect the areas you claim it did. Guess your whole premise is false to begin with. I’m still not sure what part of the GBR is 250 km offshore. About 160 km is the farthest out I know of.

Well crap. Better break out the mobile goalposts!

 

Who cares about facts or evidence when appeal to emotion arguments are one’s stock in trade, eh? Who are the climate science deniers? SMH
