“Currently the warmest year on record is 1998”

I think he is repeating a false claim. I believe 1998 was downgraded by a Canadian pajama blogger who forced NASA GISS to recant and revise their record. To be correct the author should have said ‘Currently the warmest year on record is 1934.’

While this may not prove anything one way or another, it sure does leave a different impression.

Actually, it does prove something -- that the lying hoaxers use false data to hype phony claims. Thus, the "different impression" is what they seek.

The specific there was the record for the U.S., not the global temperatures...though there are problems with those as well.
