Englannista löytyvät maailman vanhimmat lämpötilatilastot peräti 351 vuodelta. Ne osoittavat keskimäärin 0,26 C asteen nousua vuosisadassa, aivan normaalia palautumista "pienestä jääkaudesta". Paljon nopeampia lämpötilan nousuja on tapahtunut paljon ennen ihmisen globaalia vaikutusta ja hiilidioksidia, kuten alla olevat 30 vuoden väleillä lasketut osoittavat.
TELEGRAPH "The Central England Temperature dataset is the oldest in the world – with 351 years of temperature records drawn from “multiple weather stations located both in urban and rural areas of England, which is considered a decent proxy for Northern Hemisphere temperatures – not perfect, but decent.” Climate Cycles Change provides the analysis.
The first characteristic of the graph to note is the green trend line. That line indicates an overall warming of 0.26°C per century rate since 1659. So, for some 350 years central England, and the world, have been warming. No big surprise there since Earth has been continuously warming since the end of the Little Ice Age; and, at the end of that 350 year trend line of warming is the first decade of the 21st century"
