This is completely laughable. While the thermometers are undoubtedly very precise the way they are used makes a mockery of science. Anthony Watts has made quite a study of just how bad the weather stations are that scientist rely on for temperature data. These are stations in the wealthiest country in the world. One could guess that temperature from other parts of the world would be even less reliable.
A few inaccurate stations doesn't change the picture. And there have been numerous weather stations in Third World countries maintained by First World entities (like the Dutch East India company) that provide valid data over decades. And should temperature data from Australia, or New Zealand, or South Africa be suspect?
Sorry, try again.
