It’s important to express the dire condition the reefs are in, and the devastating risks it poses to ocean and human life. In order to give the public the most complete understanding of what’s going on - and how we can fix it -reporting on coral bleaching should not only link the phenomenon to climate change, but link climate change to its main culprit: the fossil fuel industry

Record levels of heat in the ocean are causing once-colorful coral reefs around the world to bleach a ghostly white. In April, the National Oceanic and Atmospheric Administration (NOAA) announced the planet’s fourth mass coral bleaching event on record—the second in the last decade.

While they might look like plants, corals are actually invertebrate animals related to jellyfish. They get their vibrant colors from tiny algae that live on them and provide them with food. But when ocean temperatures become too hot, corals get stressed and expel the algae, losing their food source and color. Starving coral can recover if their environments improve, but the International Panel on Climate Change (IPCC) predicts that even with the Paris agreement’s allotted warming of 1.5°C over preindustrial levels, 70–90% of the world’s coral reefs will still die.

In order to give the public the most complete understanding of what’s going on—and how we can fix it—reporting on coral bleaching should not only link the phenomenon to climate change, but link climate change to its main culprit: the fossil fuel industry. Because coral reefs provide such vibrant ecosystems for sea life, mass coral death will impact economies and food security for humans as well. By protecting coasts, sustaining fisheries, generating tourism, and creating jobs, it is estimated that coral reefs provide ecosystem services worth trillions of dollars each year.

In the past year alone, we’ve seen staggering and unprecedented ocean temperatures amid widespread heatwaves. Last summer, water temperatures of more than 100°F were recorded off the coast of Florida (ABC,7/25/23). Scientists say the El Niño weather phenomenon, solar activity, and a massive underwater volcanic eruption have played a role in recent supercharged ocean temperatures, but the biggest cause of this coral crisis is undisputed: climate change. The IPCC reports that it’s “virtually certain” ocean temperatures have risen unabated since 1970, absorbing more than 90% of excess heat from the climate system. We also know that the burning of fossil fuels changes the climate more than any other human activity does.

Therefore, in order to give the public the most complete understanding of what’s going on—and how we can fix it—reporting on coral bleaching should not only link the phenomenon to climate change, but link climate change to its main culprit: the fossil fuel industry. While much reporting deserves credit for clearly making this connection, some reports from major outlets were still behind, implying the climate crisis might be some sort of act of God, rather than something humans have caused—and have the power to mitigate.

Aside from the effects of the climate crisis becoming harder and harder to ignore each year, there is a commendable movement to train journalists on how best to report on climate through a number of initiatives and organizations. There’s a lot of work to do, but these stories indicate progress since Big Media was applauding Big Oil’s efforts to clean up the Exxon Valdez oil spill in 1989 (Extra!, 3–4/90) and giving platforms to “scientists” on Big Oil’s payroll who asserted climate change was not occurring (Extra!, 11–12/04, 5–6/07).

It’s important to express the dire condition the reefs are in, and the devastating risks it poses to ocean and human life. But by only mentioning “climate change” in passing, and not discussing its causes, it comes across as a natural but unfortunate phenomenon. Not highlighting its causes means not highlighting its solutions, either. The result is a potentially paralyzing doomsday narrative that is more likely to dampen than galvanize necessary climate action—especially against fossil fuels.

A Washington Post piece (4/15/24), by Amudalat Ajasa, mentioned the “heat stress” on corals, but not even climate change, let alone the culpability of fossil fuels. The article explained the role of El Niño—a naturally occurring climate pattern that warms areas of the Pacific every 2 to 7 years—and the hope that it will soon let up and give way to La Niña, its cooler counterpart, but did not explain that the phenomenon plays a smaller role than ongoing, human-caused warming. The aforementioned Vox piece also discussed the role of El Niño, but was sure to specify that reefs have been collapsing long before this current crisis.

The feeling of alarm is justified, but journalists should remind readers that the coral bleaching crisis—and climate change as a whole—are not totally uncontrollable acts of nature. We know what is to blame. While it may be too late to avoid breaching the 1.5°C limit even if we cut emissions tomorrow, the sooner we cease burning fossil fuels, the more catastrophic impacts we’ll avoid. The message is urgent and dire, but there’s plenty that humans—especially those in power—can do, and there’s plenty journalists can do to make the public aware.
