Paleoclimate 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 had […]

As 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) identified […]

The 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 A […]

In 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 using […]

The 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).

Scientists have found sea levels on India’s eastern coast were still 1-1.5 m higher than today as recently as 500 to 300 years ago and 3-4 m higher than today between 6000 to 4000 years ago. Seas rose and fell by multiple meters (-5 m to +3 m) within 1250 years until as recently as […]

A new scientific paper affirms “all the long-term-trend (LTT) tide gauges of the world consistently show a negligible acceleration since the time they started recording in the late 1800s/early 1900s” and there is “no sign of climate models predicted sharply warming and accelerating sea level rise.” Image Source: Boretti, 2019 An accurate determination of sea […]

In the first 5½ months of 2019, over 200 scientific papers have been 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 ²²²²mainstream media sources. These […]

Despite reports of relatively high regional rates of sea level rise, the Atlantic Coast of the United States has actually been expanding in recent decades after rapidly shrinking prior to the 1960s. A 2001 Salon magazine “terror in the skies” alarmism article featured a Dr. James Hansen late-1980s prediction that New York City’s West Side […]

Instead of inundation from sea level rise, 80% of assessed Florida Bay (USA) islands grew in area during 1953-2014, prototyping a global-scale trend in island resistance to rising seas. Image Source: Zhai et al., 2019 Back in 1989, the United Nations issued a dire warning: either reverse the ongoing global warming by the year 2000, […]

During the Mid-Holocene, when CO2 concentrations were stable and low (270 ppm), Antarctica’s massive Ross Ice Shelf naturally collapsed, adding the meltwater equivalent of 3-4 meters to sea levels. Because CO2 concentrations changed very modestly during the pre-industrial Holocene (approximately ~25 ppm in 10,000 years), climate models that are predicated on the assumption that CO2 […]

Alarmists say that sea levels are rising rapidly, and unless we act now to take over the climate using the secret man-made CO2 reduction method, soon New York and even Cologne, Germany, will end up in water. At least that’s the alarmist scenario that the Truth Media like to tell us about. However, a number […]
