Coral Bleaching Just As Bad Or Worse 400 Years Ago

The Greenie lies about coral bleaching, excerpts:

Large-scale coral bleaching has raised concern about the future of the ecosystems and the impact their loss could have on biodiversity.

The fact that we are seeing an increase in bleaching even in these tough corals highlights just how serious the threat of coral bleaching is. –Dr Sebastian Hennige, researcher

The teams found the frequency of bleaching has increased since the 1800s and, despite corals’ ability to recover, there are fears they could now be approaching a "critical threshold".

Dr Nick Kamenos from Glasgow’s School of Geographical and Earth Sciences said: "It’s clear in the core data we examined that bleaching has been occurring on the Great Barrier Reef for at least 400 years, but the frequency of bleaching events has increased markedly since the early 1800s and those events have affected 10% more corals since the late 1700s.

The facts:

The claim that the frequency of bleaching events has increased markedly since the early 1800s is an utterly dishonest one. Here is the actual graph from the paper itself:



The relevant chart is "B", which shows the number of years in each decade when at least 20% of corals were affected.

As you can see, although there has been a rise since 1800, there is little difference between recent decades and the 18thC. Indeed bleaching was far worse in the 1890s and 1750s.

Worse still for the alarmists, chart "C" shows little change in the percentage of corals bleached per decade.

There is the usual nonsense about how things will get much worse. But the actual facts show a completely different picture.
