Most of the last 500,000 years have seen Earth gripped by snow and ice, with short warm periods of about 10,000 years long every 100,000 years. We live in this continuing glacial era but are lucky to exist in one of the regular short warm periods.

There is nothing at all unusual about the current warm period, except maybe that it is the period during which modern human civilisation developed.

Within our warm era, we live in a time that is not unusual either – there have been periods warmer and cooler than today, with no real evidence that mankind has caused global warming (apart from minor urban heat bubbles around mega cities).

There is evidence of a correlation between sunspots and Earth temperature, as well as suggested mechanisms to explain this link. The sun clearly has an effect on Earth temperature, and the evidence tends to suggest we could expect global cooling in the near future.

Even within historical times, the Central England Temperature Record, which goes back to 1659, shows a general rising trend since the depths of the Little Ice age, rising to a peak with the solar cycles, and now signalling a falling trend.

Statistics on human usage of carbon fuels show that it is the undeveloped world not the developed world where usage is rising most sharply. Even in emissions per head of population, it is countries like China where the significant growth is occurring. Carbon taxes and targets are costly and futile.

However when we look at how carbon dioxide affects global temperature, the effect is so small as to be insignificant. It is the behaviour of the sun we should be watching.

Ed Hoskins has looked at all of the above factors in a short but revealing essay.

The UN IPCC and others with a vested interest in the global warming scare have not bothered to check what sea level evidence says about global temperature changes.

Sea levels are very sensitive to temperature changes, and the oceanic indicators are currently reading “steady”.

So are all other thermometers.

Apart from bubbles of heat surrounding big cities, the thermometers and satellites of the world have not shown a warming trend for 17 years. This is in spite of some inspired fiddling with the records by those whose jobs, research grants and reputations depend on their ability to generate alarming forecasts of destructive global warming.

To explain this absence of warming on Earth’s surface, the warmists now claim that “the missing heat is hiding in the deep oceans”.

This sounds like a water-tight alibi, hard to disprove because of our inability to measure “average ocean temperature” directly.

However, the ocean itself is a huge thermometer – all we have to do is to read the gauges.

Most liquids expand when heated, and this property is used in traditional thermometers. They have a glass reservoir filled with liquid (usually mercury) and a graduated scale to measure any thermal expansion of that liquid.

Sea levels have been rising and falling for as far back as we have evidence, and current sea levels are lower than they were during the Roman Warm Period.

Robert Endlich has looked at the evidence still visible today:

An important turning point in British history occurred in 1066, when William the Conqueror defeated King Harold II at the Battle of Hastings. Less well-known is that, when William landed, he occupied an old Roman fort now known as Pevensey Castle, which at the time was located on a small island in a harbor on England’s south coast. A draw bridge connected it to the mainland. Pevensey is infamous because unfortunate prisoners were thrown into this “Sea Gate,” so that their bodies would be washed away by the tide. Pevensey Castle is now a mile from the coast – further proof of a much higher sea level fewer than 1000 years ago.

Before modern Italy, the region was dominated by the famous City States of the Mediterranean, among which is Pisa, with its picturesque Cathedral Square and famous Leaning Tower. Located near the mouth of the Arno River, Pisa was a powerful city, because maritime trade brought goods from sailing ships right into the port. Its reign ended after 1300 AD, the onset of the Little Ice Age, when sea levels fell and ships could no longer sail to her port. Once again, some say “river silting” was the cause.

However, Pisa is now seven miles from the Tyrrhenian Sea, with large meanders upstream from Pisa and little meandering downstream. When a river is “at grade,” the downstream gradient is as low as possible, as with the meandering Mississippi River and delta in Louisiana. Rivers with a strong downstream gradient flow to the sea in a direct route, with few meanders, as with the Rio Grande in New Mexico.

The facts of history are clear. Sea level was 400 feet lower at the end of the Wisconsin Ice Age, 18,000 years ago. Sea levels rose rapidly until 8,000 years ago. As recently as 1066, when the Normans conquered England, sea levels were quite a bit higher than today.

During the Little Ice Age, 1300 to 1850 – when temperatures were the coldest during any time in the past 10,000 years – snow and ice accumulated in Greenland, Antarctica, Europe and glaciers worldwide. As a consequence, sea levels fell so much that important Roman Era and Medieval port cities (like Ephesus, Ostia Antica and Pisa) were left miles from the Mediterranean.

Since the Little Ice Age ended about 160 years ago, tide gages show that sea level has risen at a steady rate – with no correlation to the rise in atmospheric carbon dioxide levels.

Sea level is a dynamic property in our planet’s climate cycles, which are closely linked to changes in solar energy output and other natural factors. It is unlikely to change in response to tax policies that make energy more expensive and economies less robust – no matter what politicians in Washington, Brussels or the United Nations might say.

Much to their chagrin, Mother Nature doesn’t listen to them. She has a mind of her own.

Robert W. Endlich served as a weather officer in the US Air Force for 21 years and a US Army meteorologist for 17 years. He was elected to Chi Epsilon Pi, the national Meteorology Honor Society, while a basic meteorology student at Texas A&M University. He has degrees in geology and meteorology from Rutgers University and the Pennsylvania State University, respectively, and has studied and visited the ancient sites of Rome, Ostia Antica and Pisa.
