One of the poster children of global warming is the island nation of Tuvalu, an island selected because it was claimed that it would be the first nation to disappear from the map.
A new Atlantis? Maybe. But not all scientists agree that Tuvalu’s future is underwater. Some critics have branded island leaders as opportunists angling for foreign handouts and special recognition for would-be “environmental refugees” who, they say, are exploiting the crisis to gain entry to New Zealand and Australia. Others have even said that people and organizations sympathetic to Tuvalu are “eco-imperialists” intent on imposing their alarmist environmental views on the rest of the world.
Ecoimperalists used this island, starving polar bears and other emotional tactics to push an eco-fascist agenda costing in the trillions and trillions of dollars that could be spent on far more pressing and important issues. The problem by is, basing the entire reason for your existence on a lie you are certain to be disappointed by the facts. It turns out Tuvalu isn’t sinking into a swamp, it is actually INCREASING IN SIZE.
This humorous example of just how misguided global warming hysteria is, does, however, expose a more serious issue. Sea Level is a relatively objective measure, global surface temperatures are highly subjective and routinely and continually “adjusted.” People can see the high water marks on bridges, cliffs, rocks, piers and other ancient geologic structures.
If global temperatures are in fact increasing at an increasing rate, glaciers would be melting at an increasing rate, and in turn, sea level would be increasing at an increasing rate…it isn’t.
The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets. The oceans are absorbing more than 90 percent of the increased atmospheric heat associated with emissions from human activity.
The above quote is from NOAA, and at the top of the page, they do claim sea level is increasing at an increasing rate.
Is sea level rising?
Yes, sea level is rising at an increasing rate.
There is tremendous variation in global sea levels, they are flat between 2016 and today, they fell shortly after 2010 and in the mid-1960. One thing for certain, sea levels have been increasing since the end of the last ice-age/glaciation, and today’s rate of change is at the extreme low end of the range. Also, while CO2 and sea level are likely relatively correlated over the past 150 years, both have been increasing together since data for CO2 since the mid-1800s, that isn’t the case for the period prior. CO2 was relatively flat for the past 15,000 years, yet sea levels increased dramatically, and at a much higher rate. Only by cherry picking the time frame does the data support NOAA’s claim.
The other problem with NOAA’s claim is that thermal expansion is causing much of the sea level increase. NOAA claims that “the oceans are absorbing more than 90 percent of the increased atmospheric heat associated with emissions from human activity.” That is pure nonsense. First, the oceans are warmed by incoming visible radiation and contain 2,000x or more energy than the atmosphere. You could transfer all the energy from the atmosphere to the oceans and it wouldn’t register a temperature increase on even the most sensitive thermometers. Second, the only mechanism by which CO2 could warm the oceans is through the back radiation of 13 to 18µ LWIR radiation. Those wavelengths simply don’t penetrate or warm water. Lastly, the increase in daytime temperatures is due to incoming warming visible radiation, wavelengths that are transparent to CO2. In reality, the atmosphere doesn’t warm the oceans, the oceans warm the atmosphere. Water vapor absorbs far more of the LWIR spectrum than CO2, and the air above the oceans are saturated with water vapor, negating any additional contribution by CO2.
While slimate clientists have had plenty of time to “adjust” the ground measurements for temperatures to fit their models, they haven’t had as much time and ability to adjust other data sources. Ground-based temperatures have been the focus of adjustments, creating a means to expose the fraud.
Relatively unadjusted climate data include the NASA Satelite and Balloon temperature measurements, and sea level rate of change. Out of all the data sets that are available for climate research, only the highly “adjusted” ground measurements support the claim of AGW, but even those claims have weakening support. In any real science, when presented with objective unadjusted data or subjective “adjusted” data, the real scientist would choose the raw data. If slimate clience were a true science, they would be using the evidence presented by the sea level rate of change, satellite and balloon data as evidence that climate change isn’t a threat to humanity. Only when you want to make the hysterical claims of pending catastrophe would a propagandist choose the data “adjusted” to make that very case. That data is the ground-based temperature measurements, the least reliable and most heavily “adjusted” of all data sets. That is evidence of fraud, not science.
