Re-reconfirming that the Earth is warming
From Ars Technica - Berkeley Earth project is back to re-re-confirm Earth is warming.
A few choice quotes:
Once again, the more recent results are all within the statistical noise of the three mainstream temperature records. For a century and a half, Berkeley Earth is telling us what we already know. The data from before 1750 comes with a full degree Celsius of error on either side of the value. It suggests that the climate was roughly even prior to industrial times, although with very significant short-term variability…
It’s not exactly a sophisticated analysis, and others have reached the same conclusion using far more appropriate methods. Nevertheless, it’s another indication that it’s hard to make sense out of our current trends in climate without recognizing that the greenhouse effect is real.
In fact, as we mentioned in our initial coverage of the Berkeley Earth work, a lot of the papers have a substantial overlap with the existing literature. So much so that it’s not clear that Muller and his collaborators will have an easy time getting them published.
