.... What can accurately be inferred from the chart is that Brisbane experienced "unequivocal global warming" only after climate scientists unequivocally adjusted up the original (RAW) temperatures of the late 20th century, and unequivocally adjusted down the temperatures in the early 20th century.
This is just not an isolated case, but the tip of the proverbial iceberg. As more are discovering, temperatures across the world have been methodically "adjusted" in the same manner to create or enhance the warming of the temperature record. Recent examples of discovered manipulation of the temperature database include: China; Darwin, Australia; Nashville, USA; New Zealand; Siberia, Russia; the Nordic countries; Alaska, USA; Switzerland; New York City, USA; California, USA.
How much global warming has occurred in during the post-1970s? Based on this new evidence, it appears not very much. And most importantly, the claimed warming by alarmists is not "unequivocal," instead it's a fabrication.
