Genetic Rescue Efforts Could Help Coral Shrug Off Warmer Oceans

The Washington Post reports that research published last week in the journal Science indicates that coral reefs may be less vulnerable to ocean temperature changes than has been widely believed, especially given human intervention. A slice: Some corals already have the genes needed to adapt to higher ocean temperatures, and researchers expect those genes will naturally migrate and mix with corals under stress over time ... And that process could potentially be sped up artificially. ... Giving coral evolution a boost isn't an entirely new concept. Some scientists have already suggested genetically modifying corals through artificial breeding, or doing the same for the tiny microbes that live inside corals and are essential to reef growth.

"Adds heat" is a woefully inadequate simplification of whether or not it's an issue to be concerned with. When temperature goes up, other things change as a result of the relevant phsyics. For instance, the evap/precip cycle accelerates, carrying more warm air and moisture up, and more cool air and moisture down. CO2 in the upper atmosphere reduces radiation by a factor, but more heat up there, more often, increases radiation. More CO2 almost universally implies conditions better for plants. More and healthier plants means more of all sorts of things and less of others.

Dire predictions: Warming moves the zone(s) within which plants and animals flourish north. There's plenty of room to go, a great deal of northern area is frozen wasteland at this point. More CO2 is good for plants. People might have to move. They do that all the tiime. Coastlines may change and infrastructure may need to maintained, adapted, moved or replaced. That happens all the time. Currently estimated timescale for sea level changes: inches per year. Totally yawn-worthy.

In short, the issue is complex beyond any possible "on noes, warming" assessment -- hysteria is entirely uncalled for.

Science is a method. When facing something new, it involves formulating a hypothesis, testing that to validate or disprove it, and then drawing conclusions. We have not seen and do not know what happens when CO2 increases by large amounts due to our production of it. In the historical record, CO2 increases trail warming, not lead it -- which is another way of saying that historically speaking, CO2 increases herald cooling, so that is not any kind of adequate confirmation of the idea that human-caused CO2 increases will lead to significant climactic warming. Doesn't mean it won't -- it just means that this is a new thing and that drawing conclusions either requires flawless modeling that takes everything significant to the process into account (which we don't have... not only in re natural processes, but in re unanticipated technology), or actually seeing what happens. Without one of those - which again, we don't have -- it's not settled science. It is unvalidated hypothesis.

o Yes, we should be trying to figure this out.
o No, we have not figured it out.

When will we know when we have figured this out? When we have a model that accurately predicts climate change as known to have occurred in the historical record.

PS: coral does not "die when you touch it." I have multiple coral reef tanks. I touch my corals (hard ones and soft ones) all the time to move them around, frag (subdivide and transplant) them, brush them when I'm reaching for something else. I cut colonies of soft corals with a razor in order to divide them into more than one instance and place them in multiple places and/or share them with other coral reef owners. Certainly doesn't kill them (doesn't even seem to hurt them.) For hard corals, you break them into separate instances (frag them) with tools that are basically smallish hammers and chisels. You even do this out of the water. Again, doesn't kill them. They don't die because they were bothered or touched. I've never, ever seen that happen. Some of them don't react at all or very much, but the most I've ever seen them do is pull away or retract, dependably to return to their original extension and condition within minutes of the disturbance that caused it ending. Fish touch them all the time as well. Doesn't hurt a thing.

The things that I have seen be directly and immediately detrimental to corals are Ph changes, temperature changes, salinity changes, very large and sudden changes in lighting, and the actions they engage WRT each other (chemical warfare among corals has to be seen to be believed. They are nasty to each other at times.)

Climate change panic bores me. Climate change dismissal bores me. But, like a lot of other induced hysteria, it's a major component of pop culture and the media's slavish devotion to fanning same, so I have to actually work to avoid both. :)

The atmospheric studies used to make this argument are based on the planet Venus where CO2 is not a trace gas but is actually one of the dominant gases in the Venusian atmosphere. On earth, CO2 is a trace gas.

Its impact on climate heat trapping is unlikely to be relevant beyond its relative atmospheric concentrations which are tiny.

As to CO2 being a green house gas... Every gas is a green house gas in that every gas absorbs certain spectrums of light.

CO2's distinct absorption specturm is also very small. Nearly all of the spectrum that CO2 absorbs is already absorbed by water vapor and there is far more water vapor in the air than there is CO2.

Thus you're talking about a trace gas with a sliver of the EM spectrum.

The argument that a relatively small change in the percentage of the atmosphere that is made up of CO2 will lead to run away global warming is asinine.

And to further back up my position, the climate models that keep being heralded as proving the theory keep failing to predict anything accurately requiring them to be retroactively altered and past mistakes white washed.

Listening to the climate change lobby reminds me of listening to the old Soviet Politburo in that "the future is always the same... it is the past that keeps changing". That is a bit of dark humor from the Cold War. That is, the future prediction always remains the same... but you have to keep changing what you said in the past and white washing out of the bogus predictions.

Behold the bright communist future... never mind that we said we'd already be living in paradise by now 30 years ago. Keep working comrades for the brave new world.

And your point is "beware climate change, the world is going to go through these changes... never mind that we said New York City would already be under water by 2015."

This whole AGW argument has been going on long enough that your far out predictions are catching up with present time. And without exception they're all wrong.

I mean... you've been wrong about EVERYTHING. And yet you presume to claim you can predict a future you've thus far utterly failed to predict with any accuracy... even in gross terms. I'm not asking you to predict what temperature it will be on any given day. But you can't even get your graphs straight.

A little humility would go a long way from you people. You don't have the track record to justify this arrogance.

As to your point about reading the abstracts. That's not enough. You need to actually have the study itself vetted. And peer review does not do that.

These studies are getting busted all the time for making things up or using really sloppy methodology that could be "interpreted" to mean anything... often transparently the author had a conclusion they wanted before even starting the study.

That isn't real science. That's what creationists do. You have to do your study with an open mind and accept whatever the study might say. No forming your theory before the data comes in and no shaping the data to fit your theory. It is FINE to have a hypothesis before you start the study. But it can't go beyond that until you've actually got the data in... and then you base the theory on the data... you do not shape the data to equal your hypothesis.

And that is frequently what is going on.
