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 […]

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 […]

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, […]

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 […]

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 […]

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 […]

Share this… Facebook TwitterIn 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 […]

Share this… Facebook TwitterContrary to what would be expected with alarmingly high sea level rise rates, shorelines across the world are expanding rather than retreating into the sea. A few months ago we highlighted an analysis of the post-2000 net expansion (from 1007.60 km² to 1069.35 km², or +6.1%) in coastal land area for 221 […]

Share this… Facebook TwitterOver 700 low-lying islands in the Pacific and Indian Oceans have coasts that have been stable to expanding in size since the 1980s. The relative sea level rise has only been +0.46 mm/year in these regions with “almost trivial acceleration of +0.0091 mm/year²”. The claim that sea levels are rising so fast […]

Share this… Facebook TwitterClaims that rising sea levels led to a remote island species’ demise is contradicted by evidence that sea levels were meters higher than today a few thousand years ago. In 2019 Australia’s government announced that climate change – rising seas, specifically – had claimed its first-ever mammalian victim: a rat. Photo: State […]

Share this… Facebook TwitterDespite sea level rise, 1984-2019 satellite data show coastlines have been globally expanding by a net +0.26 m/year. A new study affirms what satellite data have been telling us for years: “the global coastline is prograding” (Mao et al., 2021). Image Source: Mao et al., 2021 Growing islands, beaches, coasts “all over […]

Share this… Facebook TwitterThe discovery of whale bones and marine shells at ancient beach sites 32 to 36 meters above today’s shorelines have been dated to the Early to Middle Holocene. Beach ridges were still several meters higher than today during Roman and Medieval times. The relative sea levels of the ancient past can be […]
