How global warming is permanently reshaping the Great Barrier Reef

Great Barrier Reef Before & After

Bleached corals turn a ghostly white color underwater. If they can't recover quickly enough, the bleached corals die and algae coats the once-colorful surface.

Most thriving cities boast complex architecture — tall towers looming over narrow alleyways and plenty of nooks and crannies packed with life. Coral reefs are the cities of the undersea world, gradually constructed by the soft-bodied animals that build hard skeletons around themselves.

According to a new study in Nature, the Great Barrier Reef — the world’s largest coral system — experienced two widespread coral bleaching events in 2016 and 2017 that did more than just damage thousands of miles of corals.

The bleaching and subsequent coral death, caused by unusually warm water, also impaired the reef’s ability to replenish and repair its architecture. The study found that afterward, the number of newly born corals landing on the reefs dropped 89 percent below average historical levels.

Moreover, these recent replacement baby corals weren’t the table-shaped or big branching species that provide the most “city” architecture. Even if the reef is someday covered in coral once again, the structure itself won’t be the same, with consequences for the reef’s biodiversity.

The Great Barrier Reef has rebounded from cyclones and smaller bleaching incidents before, the researchers said. It’s made up of some 3,000 interconnected reefs, so in the past if one reef got damaged, others nearby could resupply the area with new corals. But the modern bleaching events — with their massive scale and increasing frequency — could put an end to that recovery cycle.

The natural world can help save us from climate catastrophe

Ecological restoration can be a powerful means of protecting the atmosphere – we need to rewild on a massive scale

don’t expect much joy in writing about climate breakdown. On one side, there is grief and fear; on the other side, machines. I became an environmentalist because I love the living world, but I spend much of my life thinking about electricity, industrial processes and civil engineering. Technological change is essential, but to a natural historian it often feels cold and distancing. Today, however, I can write about something that thrills me: the most exciting field of research I have covered in years.

Most climate scientists agree that it is now too late to prevent 1.5C or more of global heating only by cutting our production of greenhouse gases. Even if we reduced our emissions to zero tomorrow, we would probably overshoot this crucial temperature limit. To prevent a full-spectrum catastrophe, we need not only to decarbonise our economy in the shortest possible time, but also to draw down carbon dioxide that has already been released.

John Cook in the News...

In her article, Climate Change Deniers Rely On These Myths, But Having A Prepared Response Can Help, (Bustle, May 3, 2019) JR Thorpe writes:

Assuming that you want to deal with the person's misinformation or skepticism and not leave the room (which you are, after all, entitled to do), there are various ways in which an argument around climate change myths can be negotiated. Australian psychologists and "debunking" experts John Cook and Stephan Lewandowsky propose a fact-based conversation that doesn't engage too much with the myths of the other side.

Faith Science Alliance Logo

Faith Science Alliance for Climate Leadership

The purpose of this coalition of scientists and faith leaders is to advocate for public policies in Massachusetts that address the ecological and moral emergency of climate change with bold, swift, and substantive action.

Our advocacy will be grounded in principles of justice and equity because climate change disproportionately harms those least responsible for it: low-income communities, communities of color, children, and future generations.

In support of our advocacy, we seek to educate the people of Massachusetts on the urgency of the climate crisis and our shared responsibility both to reduce greenhouse gas emissions and to adapt to the changing climate.
