A new study dispels the claim that coral reefs are at risk from modern environmental changes or rates. From about 8000 to 6000 years ago the Great Barrier Reef (GBR) relative sea levels were ~2 meters higher and seas were rising at rates of ~6 to 7 meters per millennium (6-7 mm/yr). The Early Holocene […]

Warmer sea surface temperatures are associated with coral growth, not decline. According to a new study, coral growth was slow during the ~1°C colder Little Ice Age (LIA), but grew rapidly as sea surface temperatures (SSTs) warmed after 1850. Warmth is associated with coral growth, whereas colder SSTs are linked to growth rate decline. “The […]

Scientists report a surprising coral reef resilience to bleaching, as well as a growing 0.1°C per decade heat stress tolerance. The Great Barrier Reef region has reportedly warmed by 0.8°C in the last 150 years (Page et al., 2023). This is warming rate of about 0.05°C per decade. Scientists (Lachs et al., 2023) are now […]

Corals thrive in multiple-degrees-warmer-than-today waters and their growth is stunted in cooler environments. The warnings peddled by climate alarmists often characterize Earth’s 500 billion corals as critically endangered by modern global warming. But the science itself says corals have been and continue thriving in the Current Warm Period – just as they have in past […]

In 2021, several hundred more scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. These scientific papers affirm the position […]

A German analysis finds that the threatening scenarios about the imminent death of all coral reefs in a recent study cannot be justified. ==================================================== The corals off East Africa, doomed to extinction? By Frank Bosse Kalte Sonne (Translated, edited by P. Gosselin) An agency report startles readers: “All coral reefs in the western Indian Ocean […]

For decades Great Barrier Reef (GBR) warming and coral bleaching have often been assumed to be driven by human greenhouse gas emissions and/or El Niño events. But a new study finds a much larger and more robust correlation between natural cloud cover modulation of solar radiation, shallow-water warming, and bleaching. It has taken over 260 […]

New temperature reconstructions using coral skeletons as proxies reveal there has been no apparent net warming in the Great Barrier Reef, central Indian Ocean, and South China Sea since the 19th century – or even in recent decades. Coral skeletons can be used as proxies to reconstruct 1870s-present sea surface temperatures “throughout the Great Barrier […]

In 2020, more than 400 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Over 400 scientific papers published in […]

Mid-Holocene South China Sea maximum temperatures were ~3.5°C warmer (33.5°C vs. today’s 29.9°C) about 5000 yrs ago, when corals experienced an “optimum coral growth period”. There were “numerous coral bleaching episodes” even when temperatures weren’t as high, as coral bleaching is naturally occurring. Key points from a new study (Wang et al., 2021) that throws […]

A new study affirms coral reefs grow when seas are warm and rising. Growth “shuts off” during colder, falling sea level periods. Consequently, the Great Barrier Reef has experienced growth in the last 150 years – especially in recent decades. During the Last Glacial Maximum (~30,000 to 15,000 years ago), when Great Barrier Reef (GBR) […]

Marine species subjected to high CO2 extremes – 8,891 to 95,000 ppm – in their natural environments may not be adversely affected. They may even “thrive”. Earlier this year we highlighted a study that says coral reefs “thrive” near seafloor volcanic vents where CO2 concentrations reach 60,000 to 95,000 ppm. Image Source: PHYS.ORG Urchins basking in […]
