More Evidence Emerges That Mid-Holocene Sea Levels Were 1.5 to 3 Meters Higher Than Today

More Evidence Emerges That Mid-Holocene Sea Levels Were 1.5 to 3 Meters Higher Than Today

Share this… Facebook TwitterTwo new studies indicate centennial-scale sea level rise rates ranged up to 29-45 mm/yr during the period between 14,500 and 8000 years ago, when CO2 levels were 250 to 265 ppm. Modern global sea level rise rates have been reported to be 1.56 mm/yr for 1900-2018, decreasing slightly to 1.3 to 1.5 […]

Science Yields Surprises! Island Nations Growing… “Atoll, Island Stability Is Global Trend”!

Share this… Facebook TwitterDespite what we hear from the media and climate activists, hard scientific findings show that Pacific and Indian Ocean island nations are doing just fine…not at all sinking away.  Sea level rise alarmists are hip deep in exaggeration.

Recent Shoreline Changes To Pacific Islands 'Dwarfed' By Change Magnitudes Of The Past

Recent Shoreline Changes To Pacific Islands ‘Dwarfed’ By Change Magnitudes Of The Past

Share this… Facebook TwitterMost of the 1100 Pacific and Indian Ocean islands have been growing, not shrinking in size, in the last half century. Activists convinced humans are able to exert fundamental control over ocean dynamics claim the rates of sea level rise and modern climate change are so rapid and unprecedented that modern changes […]

New Study: Mid-Holocene Sea Level Was 2-3 m Higher Than Today...Rates Of Rise Reached 80 mm/yr

New Study: Mid-Holocene Sea Level Was 2-3 m Higher Than Today…Rates Of Rise Reached 80 mm/yr

Share this… Facebook TwitterMore evidence emerges that modern rates of sea level rise are approximately 20-50 times slower than natural rising rates occurring during deglaciations. In tropical areas coral reef fossils form terraces, or flat surfaces bordered by ascending sloping surfaces. Terraces are formed at or near sea level, so their relative geological presence can […]

New Study: 88% Of Venice's Shoreline Is Now Stable Or Expanding As Sea Level Rise Slows Since 1970

New Study: 88% Of Venice’s Shoreline Is Now Stable Or Expanding As Sea Level Rise Slows Since 1970

Share this… Facebook TwitterScientists have combined remote sensing data with machine learning to determine the Venice coast “is stable, or mainly subjected to accretion in the period 2015-2019.” Venice has been sinking into the sea (subsidence) at a rate of ~24 cm per century since the 19th century. Fortunately, in recent decades the regional sea level […]

New Study Indicates North American Pacific Coast Sea Levels Declining From 1952-2014

New Study Indicates North American Pacific Coast Sea Levels Declining From 1952-2014

Share this… Facebook TwitterSea level changes along the Pacific coast have not been cooperating with an alarmist narrative. New research reveals sea level rise has decelerated from ~5 mm/yr from the 1970s to 1990s down to about 1.5 mm/yr since the late 1990s along the Peruvian coast. Further, the entire North America Pacific coast has […]

New Studies Suggest Sea Levels Were 2-5 Meters Higher Than Today ~6000 Years Ago

New Studies Suggest Sea Levels Were 2-5 Meters Higher Than Today ~6000 Years Ago

Share this… Facebook TwitterDuring the much-warmer-than-today Mid-Holocene, when CO2 concentrations lingered around 265 ppm, sea levels were multiple meters higher than they are now. From about 5000 to 7000 years ago, when Earth was several degrees warmer than it is today, there was less water locked up on land as ice. Consequently, relative sea levels […]

South America's Sea Levels Were Multiple Meters Higher And SSTs 2-5°C Warmer Until Recent Centuries

South America’s Sea Levels Were Multiple Meters Higher And SSTs 2-5°C Warmer Until Recent Centuries

Share this… Facebook TwitterSeveral new and recent studies have affirmed that the waters surrounding South America – from Peru to Chile to Argentina to Brazil – were several degrees warmer and sea levels multiple meters higher than today until the Little Ice Age centuries. A new study suggests ~4,000 to 5,000 years ago coastal Argentina’s […]

A Warmer Climate, Less Sea Ice, Sea Levels 5-16 Meters Higher Than Today An 'Optimum' For Penguins

A Warmer Climate, Less Sea Ice, Sea Levels 5-16 Meters Higher Than Today An ‘Optimum’ For Penguins

Share this… Facebook TwitterA new study (Gao et al., 2022) suggests Antarctica’s sea levels (Ross Sea) were more than 16 meters higher than today ~5,000 years ago and still 5.5 meters higher ~3,000 years ago. Penguins thrived with the warmer climate and diminished sea ice. Image Source: Gao et al., 2022 “Since 1.5 kyr BP, […]

New Study: Sea Of Japan 3-6°C Warmer, Sea Levels 2-3 Meters Higher 8000-5000 Years Ago

New Study: Sea Of Japan 3-6°C Warmer, Sea Levels 2-3 Meters Higher 8000-5000 Years Ago

Share this… Facebook TwitterDuring the Medieval Warm Period surface temperatures were 1-1.3°C warmer and sea levels 1 meter higher in the southern Far East Russia study region. Another new study (Lyashchevskaya et al., 2022) casts doubt on the claims of an unprecedentedly warm modern climate. Even though the atmospheric CO2 levels were a “safe” 265 […]

Sinking Sea Level Alarmism: Study By Nevada Scientists Show Surface Motion of Continents "On Average Upward"

Sinking Sea Level Alarmism: Study By Nevada Scientists Show Surface Motion of Continents “On Average Upward”

Share this… Facebook TwitterScientists find that on average, motion of continents is currently upward. German climate science critical site Die kalte Sonne here reports on a recent study by Hammond et al (2021) titled:  “GPS Imaging of Global Vertical Land Motion for Studies of Sea Level Rise“. The study examined the rates and patterns of […]

One New Coral Reef Study Wipes Out Four Climate Alarm Narratives In One Fell Swoop

One New Coral Reef Study Wipes Out Four Climate Alarm Narratives In One Fell Swoop

Share this… Facebook TwitterCorals 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 […]
