Contra the near constant stream of alarmist predictions that sea human caused global warming is/will cause sea levels to rise at increasing rates and weather extremes to get worse, neither claim is proving true, bringing to mind a certain vertically challenged chicken and his repeated false claims of disaster.
The Permanent Service for Mean Sea Level (PSMSL), the global data bank for long-term sea-level-change information, shows there has been little or no change in either the direction or rate of global sea level changes. The PSMSL is the best, longest-running consistent system for measuring sea level. It provides good coverage for Europe, Eurasia, North America, and the Pacific Islands; coverage is lacking in South America and Africa.
Albert Parker, a guest blogger at Watts Up With That, studied the data and found no substantial change in the rate or direction of sea level change from 1900 to 1975 when compared to rates of change from 1975 to 2016, the period of purported human-caused warming. In Scandinavia and much of coastal Eastern Europe sea levels have fallen or remained the same since 1900 with no change in direction or rate of decrease since 1975. In Australia, Central and Southern Europe, and North America, where sea levels were rising or neutral from 1900 to 1975, they have remained rising or stable post-1975.
Though Parker doesn’t address this, I would argue the lack of coverage for South America and Africa should not undermine the value of PSMSL’s measurements. Because purported human-caused warming is a “global” phenomena, if something substantially different is happening along the coasts of Africa or South America than is happening around the rest of the globe, it would have to be due to unique geologic events occurring on those continents, not attributable to a global change in the rate of sea level rise.
More good news for the world (though not climate alarmists pushing weather disaster fears in order to implement their twisted version of global government), a new paper in the Journal of Geography and Natural Disasters demonstrates reality proves wrong the oft-repeated claims global warming will result in an increase in the number and intensity of extreme weather events. Extreme weather during the most recent period of warming is on the decline. The author defines extreme weather events as storms, droughts, floods, etc. that are multiple standard deviations away from the average distribution by which such events are measured.
A survey of official weather sites and the scientific literature provides strong evidence the first half of the twentieth century had more extreme weather than the second half, when anthropogenic global warming is claimed to have been mainly responsible for observed climate change. For instance, the author found periods of maximum warming or cooling rates are all in the nineteenth century or at the start of the twentieth century, with the great majority occurring prior to 1950. The data show there has been no long-term trend in monthly rainfall since 1895. There has been a substantial decline in the number and intensity of hurricanes making landfall in the United States over the twentieth century. The number of tornadoes of strength 3 and higher is down 30 percent since 1975, the year many climate alarmist identify as global cooling turning to warming. Importantly, the number of annual deaths from climate-related severe weather events has declined steadily since 1900.
