You only need about 60 surface stations

Since surface temperature changes are correlated over distances of about 1000 km (it does depend somewhat on the latitude of the stations), it turns that you only need about 60 stations to produce a reasonable surface temperature dataset. [Edit: As … Continue reading

Climate Feedback

Climate Feedback is a site on which scientists grade articles about climate science. Not only do they provide comments, they also give a final grade, indicating the scientific credibility. For example, Chris Mooney’s article on what we’re doing to the … Continue reading

Temperature homogenisation

Amazing as it may seem, the whole tampering with temperature data conspiracy has managed to rear its ugly head once again. James Delingpole has a rather silly article that even Bishop Hill calls interesting (although, to be fair, I have … Continue reading
