Cooling The Past In Ireland

By Paul Homewood

Let’s take a closer look at the GHCN temperature record for Ireland.

I mentioned earlier that GHCN adjustments had added a false warming trend to the temperature record at the long running, high quality rural site at Valentia Observatory. It turns out that the situation is actually much worse.

Altogether, there are seven current temperature stations in Ireland, which are used by GHCN. Four of these are airport sites, and only three rural.

According to the GHCN database, four of these, including the rural sites at Valentia and Malin Head, have been artificially adjusted upwards. The remaining four sites are unchanged.

So we find that the GHCN record for the whole of Ireland is based heavily on airport/urban sites, with artificial warming adjustments added at four of the seven sites, including two of the three rural ones.

At none of the sites has any allowance been made for UHI, despite the rapid growth of the airports concerned.

The GHCN record for Ireland bears no resemblance to reality. The whole thing is a joke.

NOTE

According to GISS, who in turn source the data from GHCN, the Dublin station is at the airport. However, according to the Station Metadata Database, maintained by NOAA, the station (confirmed by the GHCN reference number) is at Phoenix Park in Dublin.

Meanwhile, the Irish Met Service have data for both sites!
