Global warming, climate change, all these things are just a dream come true for politicians. I deal with evidence and not with frightening computer models because the seeker after truth does not put his faith in any consensus. The road to the truth is long and hard, but this is the road we must follow. People who describe the unprecedented comfort and ease of modern life as a climate disaster, in my opinion have no idea what a real problem is.
Another day, anotherย new studyย has sea levels 2.5 to 3.2 m higher than present from 7000 to 6000 years ago. This one is from the Arabian Sea (Oman).
Embedded mollusc carbonate deposits dated to the Mid-Holocene have been located far inland from todayโs shoreline, documenting the meters-higher relative sea levels at that time.
Sea levels were higher because less water was locked up on land as ice throughout the much warmer Mid-Holocene.
According to aย new study, eastern Mediterranean summer temperatures were 1.5ยฐC to 3ยฐC โgreater than the presentโ from about 11,000 to 7,000 years ago, when CO2 levels were approximately 265 ppm. Then the temperatures โfollowed a gradual decline towards present-day conditionsโ.

โThe MTWA also showed an increasing trend from 9โka and reached a maximum of ca. 1.5ยฐC greater than the present at ca. 4.5 and 5โka, followed by a gradual decline towards present-day conditions. โฆ The TRACE-21k-I simulation shows peak summer temperatures between 11 and 9โka, when the MTWA was ca. 3ยฐC greater than the presentโ

Another new study indicates the climate average was much warmer (19.9ยฐC) during the mid-Holocene than today (13ยฐC) in Japan. The climate here was also warmer than today ~35-40,000 and ~55-60,000 years ago, when CO2 was said to be under 200 ppm.
โThe average temperature during the period from 5.4 to 3.8 ka โฆ is 19.9ยฐC ยฑ 6.0ยฐC and is higher than the present cave temperature of 13ยฐC.โ
