Share this…FacebookTwitterFrom 1993 to 2018, the satellite altimetry sea level changes reveal both positive and negative accelerations, align with oscillatory patterns, and are dominated by internal variability (e.g., PDO, ENSO). The “forced acceleration pattern” assumed to be associated with anthropogenic global warming “has not emerged”. Image Source: Hamlington et al., 2020 Negative or negligible sea […]

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.

Share this…FacebookTwitterRapid cooling in the North Atlantic has reversed regional sea level changes and has apparently spread to the Greenland ice sheet. Image Source: Chafik et al. (2019) Despite stressing global sea level rise is worrisome and due to anthropogenic warming, Chafik et al. (2019) report a distinct cooling trend in the North Atlantic that […]

Share this…FacebookTwitterThe onslaught of paleoclimate evidence for warmer-than-now Mid-Holocene climates – when the Earth’s sea levels were meters higher than they are today – stormed through 2019. There were 107 scientific papers published this past year indicating today’s warmth isn’t even close to being unusual or unprecedented when compared to the climates of the last […]

Share this…FacebookTwitterThough the media like to tell their audience that man-made climate change is leading to more extreme weather, the data don’t support it. In fact, one could easily argue that Japan’s climate is more agreeable today. By Kirye in Tokyo and Pierre Gosselin No trend in long-term annual precipitation Over the past 100 years, […]

Share this…FacebookTwitterSurprisingly accurate nautical maps created the 17th to 19th centuries strongly suggest coastal land area in both hemispheres were quite similar to today’s. There is even evidence relative sea levels were higher than now back then. Image Source: Etsy.com Globally, coasts have grown since the 1980s Between 1985 and 2015, satellite observations indicate the […]

Share this…FacebookTwitterPaleoclimate evidence shows there is little to no link between atmospheric CO2 concentration and relative sea level. Venice, the treasure of Italy, is a city built on a mud swamp. Consequently, in the last 100 years it has sunk about 25 cm, or 2.5 millimeters per year (Munaretto et al., 2012). The lagoon city […]

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) […]

Share this…FacebookTwitterThe West Coast of North America has 20 long-term (90+ years) tide gauges measuring relative sea level changes. The East Coast has 33. Of the 53 total tide gauges, 45% (24) are negatively accelerating, 14 document falling sea levels, and just 11 have sea levels rising more than 3 mm/yr. Image Source: Boretti, 2019 […]

Share this…FacebookTwitterIn recent decades, the Earth’s seas have been rising at a rate of under 0.8 mm/year (8 cm per century) according to estimations of the sum of contributions to sea level rise. In contrast, sea levels rose at rates of more than 40 mm/year ~10,000 years ago. Relative sea level rise can be calculated […]

Share this…FacebookTwitterThe world was much warmer and greener with meters-higher sea levels just a few thousand years ago. Between 9000 to 6000 years ago, when global temperatures were 4-6°C warmer than they are today, the Sahara was a tree- and lake-covered haven teeming with megafauna and human civilizations (Manning and Timpson, 2014).
