There are many similar findings, sorry, dupe.The hell they did, dupe.By studying tree rings and other clues in our environment, scientists have learned that there have been times when most of the planet was covered in ice, and there have also been much warmer periods. In general, climate changes prior to the start of the Industrial Revolution in the 1700s can be explained by natural causes, such as changes in solar energy and volcanic eruptions. Recent climate changes, however, cannot be explained by natural causes alone. Instead, human activities are very likely responsible. Tree rings alone cannot tell us whether human activities are responsible, but they do help by revealing patterns that scientists can investigate further.Nothing there about tree rings telling you how hot it is.
Which year was the hottest for this tree?

You win a gold star, you learned today the climate has always changed, now can you figure out the resolutions on those proxys? Can you figure out you can't use them with modern temperature readings to get anything significant in a trend.
By the way man just got his tree specimens from only Siberia .
Has any piece of scientific research ever been so thoroughly discredited? Tom Wigley’s son’s high school project falsified the hockey stick. The latest Sheep mountain study shows the hockey stick disappears, unless you use Mike’s trick of splicing in the thermometer record, to hide the divergence problem. The Russian scientists who collected the original tree ring samples, tried to warn Mann he was measuring the wrong metric. Yet somehow this nonsensical analysis became a central icon of the climate alarmist movement – and is still widely reproduced by the more scientifically illiterate alarmists.
