Three further studies prove: Oftentimes it used to be warmer than today

The current warm period is being blamed on humans and CO2. However, other data from the past centuries and millennia show that such temperature fluctuations are completely natural. The focus on the trace gas is obviously misguided.

The global climate has been subject to major fluctuations since time immemorial. This has not changed much in the last few thousand years. What has changed, however, is how we deal with it. In the past, people blamed the gods, today they blame themselves. There are several different factors that interact and play their part. Solar cycles and volcanic activity included. In this respect, three new scientific studies are also revealing, which prove major climatic fluctuations even without industry and mass combustion of fossil fuels.

For example, a study on the dynamics of the climate in the Azores in the late Holocene. According to the report, the average July temperatures there are currently 10 to 11 degrees Celsius. This is 1 to 2 degrees higher than during the “Little Ice Age” (1750-1800), when the coldest period of the last 2,000 years was recorded at around 9.1 degrees Celsius. However, according to the studies by Raposeiro et al., the average July temperatures there during the so-called “Medieval Climate Anomaly” (i.e. the warm period) were 13 to 15 degrees Celsius – and therefore 3 to 4 degrees above today’s level. And that’s without industry and the massive use of fossil fuels by mankind.

A lake and its surroundings in the Pacific Northwest of the United States, Gold Lake, was also analysed for climatic changes. The published paper states, among other things, that temperatures were around 1.5 degrees warmer around two and a half thousand years ago. In the last 1900 years (which includes both the medieval warm period and the “Little Ice Age”), they have always been between 12.2 and 12.6 degrees Celsius. So there were no really significant changes.

Another recently published study analysed lake sediments in northern Finland. The data published there suggest that modern temperatures are among the coolest in the last 8,000 years or so. According to the study, it was significantly warmer than today in the period from 7,000 to 3,000 years ago and from 1,500 to 1,200 years ago, at least in this region.

These new studies make it clear that the climate is much more complex than we are led to believe. As I explained in my book “CO2 is not our enemy“, many different factors play a role. These study results support many previous findings that there is only a limited causality between global temperatures and CO2 concentrations in the atmosphere.
