New models detail consequences of high emissions for Gulf, Caribbean corals

HOUSTON – (Oct. 5, 2022) – Ocean temperatures in the Gulf of Mexico and the Caribbean Sea are on pace to surpass critical thresholds for coral health by mid-century, but rapid action to significantly reduce emissions could slow warming, giving corals and coral conservation programs as much as 20 more years to adapt, according to new research.

Climate scientists and marine biologists from Rice University, the University of Colorado Boulder and Louisiana State University used computer models to simulate climate warming from 2015-2100 under both a “business as usual” scenario with very high emissions and a scenario in which emissions were reduced to high levels. Their study and analysis of ocean warming and ocean acidification levels for specific regions in the Gulf of Mexico and Caribbean under each scenario is published in the Journal of Geophysical Research: Biogeosciences. The researchers found reducing emissions could delay the onset of critically warm ocean temperatures in some areas where reefs are still healthy.

“There are reefs in the Gulf that are really worth saving,” said Rice University marine biologist Adrienne Correa, a co-author of the study. “Some of the healthiest reefs that we still have in the United States are in the areas covered by these projections.”

Live coral cover on reefs has declined worldwide by about 50% since 1950, and few reefs in the Caribbean and Gulf have more than 10% live coral cover. Reefs in Dry Tortugas National Park in western Florida and in the Flower Garden Banks National Marine Sanctuary off the coasts of Texas and Louisiana are notable exceptions with more than 50% live coral cover.

The study found ocean temperatures in the Caribbean and parts of Florida could reach critically warm temperatures as early as 2050, posing a serious risk for coral survival.

“The fact that we’re going to see these changes by 2050 is a strong wake-up call,” said Correa, an assistant professor of biosciences whose lab specializes in studying corals and reef ecosystems. “We get a lot of bad news about reefs, but we can still draw hope and motivation from this. Some of the reefs that are included in this analysis are really special, like the Flower Garden Banks, and reefs off of Cuba and in some other parts of the Caribbean where there’s still really high coral cover. We can help protect and keep the high-coral-cover reefs we have if we take immediate action to shift how much energy we use and where we get our energy.”

Correa co-authored the study with climate scientists Sylvia Dee of Rice, Allison Lawman of CU Boulder and Kristine DeLong of LSU.

“In one case, we have more time to mitigate, and in the other we don’t,” said Dee, a climate modeling expert and assistant professor of Earth, environmental and planetary science. “People need to be aware this is coming up fast, and the time to explore mitigation techniques is now.”

Corals are symbiotic organisms that live in partnership with photosynthetic algae that help feed their coral hosts. Corals are also builders that draw upon carbonate minerals in seawater to construct their own rocky outer frameworks. Climate warming threatens both coral symbiosis and coral reef-building. For example, heat stress can cause corals to expel their symbiotic algae en masse, a sometimes deadly phenomenon known as bleaching. And oceans become more acidic as they warm, reducing the efficiency of the chemical reactions corals use to build reefs.

Previous studies have shown that heat-related coral bleaching is often triggered by prolonged, abnormally warm ocean temperatures. The critical threshold temperature for bleaching varies between ocean regions and reefs. For example, the threshold temperature for reefs in the Flower Garden Banks is 29.5 degrees Celsius (85.1 degrees Fahrenheit). The researchers analyzed regional warming patterns in each scenario to project when specific regions with coral reefs were likely to reach threshold temperatures under each emissions scenario. A similar regional analysis was performed to project the timing of critical thresholds for ocean acidification.

Lawman, the corresponding author of the study and a former postdoctoral scholar in Dee’s lab, said the study showed heat-related stress was the biggest and most immediate climate-related threat to corals under each emissions scenario.

“The difference was whether you crossed the critical thresholds around 2050 versus 20 years later,” said Lawman, a postdoctoral associate at the Cooperative Institute for Research in Environmental Sciences at CU Boulder.

The researchers found the key determinant of coral mortality in each scenario was the number of months that corals in the future will be exposed to prolonged temperatures hotter than the hottest average months projected for 2015-2034. The researchers dubbed these “degree heating months.”

“There’s always one month that is the hottest of the year,” Lawman said. “Let’s say it’s August and the average baseline temperature for that month is 29 degrees Celsius in the region we’re studying. A ‘degree heating month’ in that region is any month in the future that has a higher average temperature than 29 degrees Celsius.”

The research showed that under the “business as usual” emissions scenario, “degree heating months” become the norm in the late 2100s, occurring as much as 10 months out of the year in some parts of the Caribbean.

“That’s a huge number of months in which corals could experience thermal stress beyond the usual levels to which they are adapted,” Lawman said.

“These projections are very concerning,” she said. “I think the takeaway message is that the time to act is now.”

DeLong is an associate professor of geography and anthropology at LSU.

The research was funded by the Gulf Research Program of the National Academies of Sciences, Engineering and Medicine, Rice University, the Department of the Interior (G19AC00086) and the National Science Foundation (2102931, 2109622).

More research is needed on coral behaviour, as the current lab research doesn’t match the robustness of coral, say, of the Great Barrier Reef, or off Indonesian coasts in much hotter water.

The amount of warming in all scenarios is fiction based, so they might as well use the scariest. In addition, the IPCC projections for warming though 2050 have less than 2/10 the of a degree of difference between RCP 8.5 and all the other scenarios (other than constant composition), so the results would be similar.

Did anyone build an Excel ‘water world’ (as I suggested how to do aaaaages ago) to find out what Earth’s temp would be.

A Water World being an Earth with no atmosphere and comprised only of deep crystal clear water.

Here’s the result for a point on the equator:
Incoming solar: 1,375 watts per square metre
Albedo =0.06 (actual figure for water normal incidence)
Emissivity= 0.95 (It’s close to unity but not quite)

If Earth was not rotating, the average energy entering water (from East to West) would be 1375 x (1-albedo) divided by root(2) = 914 Watts/sqm

But water absorbs all that energy to considerable depth (100 metres) and Earth is rotating
So, the water will be absorbing 914 watts for 12 hours and Zero watts for 12 hours each day.

The water will accumulate energy, its temperature will rise until, over the course of 24 hours, it radiates away the energy it receives in each 12 hours ‘day’

So, when the water gets to equilibrium, it will be radiating away half of 914 watts via its Emissivity of 0.95

Via Stefan. I get a figure of 304 Kelvin or 31°Celsius

Which is almost exactly what is recorded – How Many Times has Willis told us that – and wondered why it happens?

There it is, I just worked it out from very first principles.
Anybody could. Why did they not?

Ah you say, the water will cool overnight and not radiate as much
The energy was absorbed into a 1 metre square of 100 metre depth.
if 100 cubic metres of water (this is what slaughters the GHGE) lost energy at that rate, over a 12 hour (nighttime) period it would cool (my calculation) by 0.05°Celsius

So by their very own authority and the maths of a 13 or 14 year old child, there is No Way that deep water on Planet Earth can get hotter than 31°C

(Shallow water can if the mud under is is very dark coloured)

Build the spreadsheet in (say) 5° steps of latitude to take that calculation across (Equator to Pole) the entire Earth and you get an average temp of 10.4°C
Do it properly, sum the TempxArea then divide by the Total Area to get the Average Temp)

A lovely thing you see is that at 40°of Latitude, temp reaches that 10C figure.

And also you see the oft quoted ‘crossover point’ = where we’re told that below that latitude Earth absorbs heat and above that latitude, Earth loses heat

It’s also, roughly as best anyone know, the lowest latitude extent of the so-called Snowball Earth events

The average temp of the 50° latitude point is = Zero Celsius – does that explain ‘Canada’

Ah but then you say, Earth is not all = water.
Yes heats up faster and hotter than water does.
But there are 2 hideous complications..
Land does nor store energy like water does (to 100 metre depth) so it will cool much faster at night

But, when it is growing perennial plants, they are made of water and will store the heat.
Dead and buried plant material in the ground likewise.
Will that cool or warm
What happens if the perennial plants die or are replaced by annual plants.

THAT is what Climate Computer Models should be working on……..

Albedo =0.06 (actual figure for water normal incidence)

Emissivity= 0.95 (It’s close to unity but not quite)

What of the relation between the so-called shortwave reflection component (albedo) and the emissivity of the longer waves….

The sum of 0.95 + 0.06 almost precisely unity. what of that? An emissivity of 0.06 is suggestive of a longerwave reflectivity of 0.94. How can the shortwave and longerwave reflections be so similar… a nearly perfectly unnoticeable swap of an apple for an orange.

As the incident solar beam is composed of upwards of 50% in the IR portion of the spectrum, it offers a clue.

Such that from an Earth System perspective, plugging in our approximate 30% shorterwave albedo reflection yields a ballpark swap of 30% reflection of the longerwaves also.

And so a deduced Earth system emissivity of 0.7 to plug into our spaceborne thermal IR gun calibration. Where 100% – % Reflected = Emissivity

Emitting 240 Watts/m2 of power observed, adjusting the emissivity dial to 0.7, gives an active planetary radiating temperature of 278K. Considerably warmer than the 255K conjecture.

An emissivity of 0.06 is suggestive of a longerwave reflectivity of 0.94.

I have inverted the lingo in all the swapping and interchangeability. Longerwave emissivity 0.95 suggests longerwave reflectivity of 0.05.

Albedo =0.06 (actual figure for water normal incidence)

For an instant at solar noon, in deep water, for visible light. Thereafter, the specular reflectance component slowly climbs until at about 60 degrees it starts to climb rapidly, reaching 100% when the point is on the terminator. At the same time, the apparent diffuse reflectance from suspended sediment and plankton varies inversely, reaching zero at the terminator because no light actually enters the water at a glancing angle.

I remember an entire day of ignorantly entering values into a simulator in engineering school hoping to get a certain transfer function that a professor wanted to see from a then-novel transistor type. I succeeded. Then I graduated and joined a real company. I learned a hard lesson in the dangers of delivering impractical possible answers. I also learned that simulators are easy to build but difficult to get right without excellent understanding of what they should simulate, and learned that the best way to run a computer simulation program is by using my own computer program to simulate everything I am willing to do to torture the desired answer from it.
Based on learning that might not apply to the specific situation in the main article, I worry that the writers went places they didn’t think they would go chasing down results they were told to get to make someone who knows enough to get “the real answer” instead, but does not want to own it. They’d be better educated if they’d used their time scripting data input instead of learning to dislike data reentry.

Separate note on corals, as I have the only coral reef in the continental US about 300 meters off my beach and love diving it. As with most coral reefs, several different species co-exist here.

When they bleach they are expelling their symbiotic photosynthetic zooantellae. They can survive about 6 months before taking up a better adapted symbiotic system species. If they don’t, they slowly die of starvation. But that reef section will still repopulate within 10 years from coral spawn.

Corals reproduce two ways. They bud continuously, which means the epigenetically adapted phenotype for that location’s conditions is directly reproduced. And once a year they spawn sexually, which means the DNA maintains diversity for evolution.

Biggest dangers to corals are overfishing (fish eat the green algae that could otherwise smother them) and pollution. The big pollution problems here in south Florida are fertilizer run off (encouraging smothering green algae) and sediment runoff (that directly muddies and blocks needed sunlight). We used to dredge sand from beyond the reef to replenish the beach, but now the dredging would stir up the sediment and damage the reef. So this last go we trucked in about 400,000 cubic yards of washed clean sand from a mine in central Florida to replenish the beaches. Advantage was the sand is slightly coarser, so holds place better. But expensive trucking—$60 million to replenish about 10 miles. With dredging, was about 10 last go.

This is a question about Ocean Acidification.

Why is that when the pH of a solution moves from pH7.8 to pH7.6 it is said to become more acidic when it still lies in the basic range. Shouldn’t it be less basic ?

Also, I ran the question through an AI and got the more acidic answer but then asked it “what happens to the pH if it changes from pH6 to pH6.5” and it answered the solution has become less acidic – shouldn’t it be more basic ?. Is pH always described in terms of acidity or has logic gone out the window 🙂

Conveniently forgotten from their “calculations” is how many new acres of coral develope in areas that are currently too cold. Even by IPCC declarations, temperature increases in the future will be greater near the poles than the equator, so more warming where it’s needed versus where it is already warm.
