GHCN Unadjusted Data Show Zanzibar Has Seen A Cooling Trend Since 1880!

What follows is the data from the Tanzanian Island of Zanzibar in the Indian Ocean.

▲ Data Source

NASA’s website tells us that the GHCN V3 Unadjusted data gives the mean annual temperature up to 2007, despite the V3 dataset being updated up to July 2019, and the trend is a cooling.

According to NASA, in the GHCN V4 dataset, the station has the mean annual temperature data after 2007, not only the data of up to 2007 from 1880.

What is worse, the GHCN V4 Unadjusted data show Zanzibar has seen a cooling trend since 1880, but the GHCN V4 adj – homogenized show that the island has had a warming trend.

▲ GHCN V4 Unadjusted vs. GHCN V4 adj – homogenized

I wonder just how much NASA likes data alteration?

Don`t worry there is no significant man- made global warming. The global warming scare is not driven by science but driven by politics. Al Gore and the UN are dead wrong on climate fears. The IPCC process is a perversion of science.
