New Study: Coral Bleaching 'Repeatedly Occurred' Throughout The Warmer-Than-Today Mid-Holocene

New Study: Coral Bleaching ‘Repeatedly Occurred’ Throughout The Warmer-Than-Today Mid-Holocene

Share this...

Share this…FacebookTwitterMid-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 […]

Alarmism Dies In The Great Barrier Reef As New Study Documents Reef Growth Since The 1970s

Alarmism Dies In The Great Barrier Reef As New Study Documents Reef Growth Since The 1970s

Share this...

Share this…FacebookTwitterA 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 […]

When Exposed To Natural, Long-Term Extreme 'Ocean Acidification', Coral And Urchin 'Persist' And Even 'Thrive'

When Exposed To Natural, Long-Term Extreme ‘Ocean Acidification’, Coral And Urchin ‘Persist’ And Even ‘Thrive’

Share this...

Share this…FacebookTwitterMarine 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 […]

New Study: Coral Reefs Thrive Near Acidic Waters (pH ~6.0) Where Seafloor Vents Emit Up To 95,000 ppm CO2

New Study: Coral Reefs Thrive Near Acidic Waters (pH ~6.0) Where Seafloor Vents Emit Up To 95,000 ppm CO2

Share this…FacebookTwitterThough it’s believed the 130 ppm increase in atmospheric CO2 concentration since 1750 has caused the ocean waters to “acidify”, on a daily basis 50-380°C metallic acid enriched by CO2 concentrations reaching 60,000 to 95,000 ppm pours through seafloor vents. Nearby coral reefs “thrive” in these high-CO2 conditions. Image Source: PHYS.ORG 50 times more […]

Over 440 Scientific Papers Published In 2019 Support A Skeptical Position On Climate Alarm

Share this...

Share this…FacebookTwitterIn 2019,  more than 440 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.

4 New Papers, One Alarm-Dispelling Conclusion: Future Sea Level Rise May NOT Threaten Islands After All

4 New Papers, One Alarm-Dispelling Conclusion: Future Sea Level Rise May NOT Threaten Islands After All

Share this...

Share this…FacebookTwitterAs reported in 4 separately-published papers, scientists have discovered a mechanism whereby islands can build themselves up naturally, thwarting the threat of sea level rise.  Tuck et al. (2019) affirm the “implications of island building are profound, as it will offset existing scenarios of dramatic increases in island flooding.” Earlier this year, Duvat (2019) […]

A New Study Finds Rising Sea Levels PROTECT Coral Reefs From Bleaching And Mass Deaths

A New Study Finds Rising Sea Levels PROTECT Coral Reefs From Bleaching And Mass Deaths

Share this...

Share this…FacebookTwitterLong-term observation of coral reefs indicate rising sea levels “not only promoted coral cover” but also “limit damaging effects of thermally-induced bleaching” (Brown et al., 2019). Image Source: Brown et al., 2019 This new paper  is an expansion of the research conducted by the same lead author in 2011 (Brown et al.). Brown and […]

New GBR Study: 400% Coral Recovery Since 2014 - With 2017 Growth Rates Comparable To The 1970s

New GBR Study: 400% Coral Recovery Since 2014 – With 2017 Growth Rates Comparable To The 1970s

Share this...

Share this…FacebookTwitterA long-term (50 years) study of a Great Barrier Reef (GBR) ecoystem finds corals may quickly recover from El Niño disturbances. According to scientists (Yan et al., 2019), coral reef ecosystems thrive in centennial-scale warming phases such as the Medieval Warm Period and Current Warm Period, whereas they experience population declines (“switch-off” episodes) during […]

Coral Mortality Rates Higher During Cold Periods - And There's Been Recent Cooling In Coral Environments

Coral Mortality Rates Higher During Cold Periods – And There’s Been Recent Cooling In Coral Environments

Share this...

Share this…FacebookTwitterIn the coral habitats of the Western Indian Ocean, SSTs have cooled by -0.8°C since the 1980s (Watanabe et al., 2019). It has long been established that exposure to extremely low temperatures induce coral bleaching and high mortality rates just as much as warm SSTs do. Further, colder periods – which are associated with […]
