Temperature Trends In West Antarctica

Five years ago, this study looked at the relationship between snowfall accumulation and temperatures in West Antarctica:

It found that there was good correlation over the last 8000 years, with higher temperatures coinciding with higher snowfall:

But the most significant item was the temperature trend itself. West Antarctica has actually been warmer than now for most of the last 8000 years.

There is even clear Little Ice Age event.

So much for “unprecedented warming”.

The temperature record is derived from ice-core data, which has been well established for some time now.

    “Five years ago, this study looked at the relationship between snowfall accumulation and temperatures in West Antarctica. West Antarctica has actually been warmer than now for most of the last 8000 years.

    How could there be a meaningful relationship between AGW (aka CO2) and global temperature today if it has been warmer in the past without our help? It has been warmer in the past almost everywhere. A cynic might say that maybe it’s because an ensemble of climate models have been adjusted to make it that way? Create a climate emergency?

    Great post. Thanks.

    Those graphs are naughty. They have different scales, it looks like the newer data has better resolution. At first I thought, “There is no correlation in the lower graph, the two series are not even closely related”. So by choosing different scales you get very different “looks” to the graphs.
    I would suggest that it is difficult to accept the correlation of the 1st half of the graph with the wide disparity between series in the 2nd.
    This is the sort of thing that Alarmists do, not sure we should be,

    Paul – Not related to this post but don’t have another way of emailing you. The BBC had an article on Japanese cheery blossom at the end of March (https://www.bbc.co.uk/news/world-asia-56574142) which was very early this year and they ascribed this to climate change. The data is available and looking at it (without cherry picking!!) from 1600 shows no discernable trend. You may want to take a look.

    I agree with RockySpears. The temperature values are so different between graph A and graph B. It is important that presentations of data are not subject to quarreling about how they are displayed. This is a very useful study and a simple unequivocal presentation would help to support the interpretations of the data.

    “In Kyoto, records of the timing of celebrations of cherry blossom festivals going back to the 9th Century reconstruct the past climate and demonstrate the local increase in temperature associated with global warming and urbanisation,”

    The key words here are not ‘global warming’ but ‘urbanization’. It has been demonstrated that the cherry blossoms in Kyoto are sensitive to the urban heat island effect, which of course goes up as the population density goes up…

    “Cherry Tree Flowering Affected by Urbanization…
    As mentioned above, cherry tree flowering times have been strongly influenced by the urban heat island effect, the warming that comes from the added heating caused by removing trees and replacing them with roads, parking lots, buildings and other aspects of a human-dominated landscape”
