BBC’s Coral Propaganda

by P. Homewood, Apr 16, 2024 in NotALotOfPeopleKnowThat


The BBC is corrupt, and this report is fraudulent:

It has triggered the fourth global mass coral bleaching event, according to the US National Oceanic and Atmospheric Administration (NOAA).

Bleaching happens when coral gets stressed and turns white because the water it lives in is too hot.

Coral sustains ocean life, fishing, and creates trillions of dollars of revenue annually.

For a start, there has been no “devastating toll”, as the BBC pretends, from the possibility that the world is slightly warmer than a few years ago. (Given margins of error, there is no certainty about this.)

But more importantly, Rannard grossly misrepresents the science. Coral does not “turn white” because the water is too hot. Nor is this is a rare occurrence, as the “fourth global mass coral bleaching event” implies.

On the contrary, bleaching is a common event, which can take place for all sorts of reasons, including when the water gets too cold.

As the leading coral reef expert Dr Peter Ridd has explained, “bleaching” is merely part of a natural process, when coral expels algae in order to switch to a different type which is more suitable adapted to new conditions.

According to Ridd, coral cover on the Great Barrier Reef last year reached record levels, despite four supposedly catastrophic bleaching events in the six years prior to 2022. Neither has there been any significant change in corals worldwide.

Rannard’s article has nothing to do with science; it is just more scaremongering propaganda.

This interview with Peter Ridd which followed his annual review on corals last year is worth watching:

Antarctica Is Colder, Icier Now Than Any Time In 5000 Years. The Last Warm Period Was 1000 Years Ago.

More evidence emerges that Antarctica has undergone rapid glacier and sea ice expansion in recent centuries, in line with the long-term and recent Antarctic cooling trend.

West Antarctica’s mean annual surface temperatures cooled by more than -1.8°C (-0.93°C per decade) from 1999-2018 (Zhang et al., 2023).

Not just West Antarctica, but most of the continent also has cooled by more than 1°C in the 21st century. See, for example, the ~1°C per decade cooling trend for East Antarctica (2000 to 2018) shown in Fig. ES

 

According to a new study, about 6000 years ago Antarctica’s Collins Glacier’s frontline was a full 1 km southwest of its current extent. The frontline advanced to today’s extent ~5000 years ago.

“Previous studies proposed that 6000 yr BP, the frontline position of the Collins Glacier was located 1 km further south west than the present, and that the current frontline was first attained at approximately 5000 yr BP.”

The glacier then continuously retreated south of the modern extent for another 4000 years, with peak ice loss 1000 years ago (as shown in the 1000-year “Proglacial lake environment” image). In the last 1000 years this glacier has rapidly re-advanced back to the glaciated extent from 5000 years ago, which is in line with the sustained cooling trend ongoing since the Medieval Warm Period.
