Nope. Not a single percent increase in measurement accuracy. Sorry. This is a famous (and particularly silly) strawman argument fashioned by the 'There is no Global Warming' crowd.
And the reason for this is that mercury have expanded and contracted through heat input exactly as much a hundred years ago as last year. Or the year before. Or today.
The last few years have been the hottest
on record. And our records, made with kick-ass reliable mercury thermometers calibrated at the freezing and boiling points of water (which, incidentally, haven't changed over the last hundred-odd years, either) go back a good hundred and fifty/two hundred years. Now what on earth does that tell you? Yeah! There's nothin' wrong! It's all a big hoax!
Err on the side of caution, like my momma always used to say. Because the alternative is unthinkable.
