Global warming may have started before industrial revolution, study says

We can’t have effects preceding causes, so something seems to be amiss with the ‘human-caused warming’ dogma, if this study is correct.

Studies of coral reefs in the Paracel Islands suggest that the South China Sea started warming up in 1825, at the start of the industrial revolution, according to a study by Chinese scientists.

That was the year the world’s first railway began operating in England and most ocean-going ships still used wind power, says The South China Morning Post.

Man-made carbon dioxide emissions could not fully explain such an early rise in the warming trend, they said in a peer-reviewed paper published in Quaternary Sciences on Friday.

The Paracel coral record “will fill in some important gaps in global high resolution marine environment records and help us better understand the history of environmental change in tropical waters”, said the researchers, led by Tao Shichen from the South China Sea Institute of Oceanology.

Coral reefs provide useful climate records because the higher the temperature the faster they grow.

The Paracels have one of the largest living reefs in the Asia-Pacific region, but in recent decades the archipelago has become the focal point of territorial disputes between China and Vietnam, and the construction of infrastructure has threatened the natural environment.

The researchers studied four coral reef samples retrieved from Yongxing and Yongle, two of the largest islands in the Paracels and both controlled by China’s military. The samples were drilled from locations that have been continuously underwater and suffered minimal disturbance as a result of human activity.

With the help of uranium dating technology, the researchers found the samples contained a continuous climate record going back to 1520. To ensure the accuracy of the results, parts of the samples were also sent to a laboratory in Queensland, Australia for independent analysis.

The results showed that the temperature 500 years ago was lower than it is today. The cooling trend lasted until 1825. From that date to the present, there was “a general trend of rapid increase” with the biggest spike reaching 2.3 degrees Celsius, Tao said.

The Chinese team is not the first to carry out such research. In 2016, an international team led by Australian climate researcher Helen McGregor examined the climate records from coral skeletons, ice cores, tree rings, cave deposits, and ocean and lake sediments across the globe.

They found that global warming could have started as early as the 1830s. McGregor and her colleagues argued that carbon dioxide emissions could be the main cause of the temperature increase because the impact of the early stage of the Industrial Revolution might have been underestimated.

But the Chinese team has a different interpretation. Though man-made greenhouse gas emissions certainly existed then, they were unlikely large enough to alter the global climate, they said.

    500 years of cooling because…? Answers to Climate Propaganda Central, UN IPCC.

    All these ‘climate scientists’ will have to get together and make sure they are reading from the same science fiction story if they want people to believe them.

    The amount of garbage produced in the name of ‘climate science’ in the last few months is astounding, maybe they are finding it harder to get grants to ‘study’ the garbage or they need a bigger and better computer to run their unvalidated models that give garbage results.

    The science is settled. Let’s get fracking and reduce power costs. ‘AGW’ is just a natural rebound from the LIA, as I posted some time ago.

    The McGregor quote really shows how this nonsense corrupts science. These results question the C02 driven hypothesis but instead of hailing a discovery that might change how we view the world they instead make CO2 even more powerful even though that makes no sense. Just dogma.

  9. oldbrew says:

    CO2 is a very minor player in the radiative gas game compared to water vapour. Alarmists don’t want people to know that.

    The Industrial Revolution is a very movable feast, eg, coal fired cupolas were in use from 1678, Abraham Derby was using coke for his blast furnaces at Coalbrookdale in 1709. Industrialists were importing iron from Sweden and Russia in the mid 1700’s. From 1785, Britain was exporting bar iron and wrought iron goods. The iron bridge at Ironbridge in Shropshire was built in 1778. The industrial use of steam power began in 1698 with the Savery engine, followed by Newcomen’s engine in 1712.

    Canals began to be built in the late 1800’s to connect major manufacturing centres in the midlands and North with a national network in existence by the 1820’s.

    The problem with history is that it doesn’t sit well with the theory of static atmospheric CO2 of 280ppm before 1850 when we are told the Industrial Revolution started and every increase since then is anthropogenic.

    Paraphrasing Jonathan Overpeck (most likely), ‘We have to get rid of the Little Ice Age.’

    Oh what tangled webs …
