Study after study has provided a multiplicity of evidence that the modern 21st century warming is not unprecedented, much to the chagrin and angst of elite alarmists and doomsday claimants.
Now we have a recent peer-reviewed study that examines 2,000 years of temperatures, which clearly reveals a past that indeed was warmer than present (see adjacent chart).
"Aside from the obvious millennial-scale climate oscillation seen in the temperature reconstruction, it is important to point out that there is nothing unusual, unnatural or unprecedented about current temperatures on the southern Tibetan Plateau (STP). As indicated by the horizontal red line depicting the current temperature, there have been multiple times during the past two millennia when temperatures were warmer than present, including the 400 year period from 850-1250 AD, despite their being 50% less CO2 in the atmosphere than there is today. Because of this fact, it is clear that rising atmospheric CO2 is having little, if any, effect on current STP temperatures witnessed during the Current Warm Period."
"But if not CO2, what is or could be the cause of the 20th century warming? Based on additional analyses performed by Guo et al., it was their conclusion that changes in solar irradiance "played the most important role in influencing the climatic variabilities over the STP on a multi-centennial timescale.""
Conclusion: Mainstream media, Democrat politicians, and Hollywood celebrities continue to spread consensus anti-science claims in regards to the current global warming facts.
