A follow up on the ‘it was warmer in 1790 in Sydney’ story

SYDNEY 1790 : Bats dropped dead “unable longer to endure the burning state of the atmosphere.”

Thank God for today’s industrial windmills – far more effective bat and bird killing machines than the evil heat-causing CO2 of 1790.

Watts Up With That?

Readers may recall the story  Global Warming?……. It was warmer in Sydney in 1790 by Craig Kelly, MP in NSW Australia in response to some of the recent alarmist caterwauling in the press about the hot summer in Australia being a sign of ‘global warming’. He writes in with an update regarding criticisms by Steven Mosher regarding instrument calibration.

Hi Anthony,

I’ve done a bit more research on the temperature measurements recorded by Tench in 1790 that  I thought you might be interested in.

Firstly, it appears the measurements were taken in a purpose built observatory which stood at location of the current pylons of the Sydney Harbor Bridge. The Observatory was built and run by William Dawes.
