It is based on the John Daly archived data:

and the current Contiguous U.S. surface temperature anomaly data from GISS:

In their presentations,

most people have been concerned

with which decade had the highest

U.S. surface temperature anomaly:

the 1940s or the 1990s.

But I couldn’t recall having

ever seen a trend comparison,

so I snipped off the last 9 years

from current data and let

EXCEL plot the trends:

Before the post-1999 GISS

adjustments to the Contiguous

U.S. GISTEMP data,

the linear trend for the period of

1880 to 1999 was 0.035 deg C/decade.

After the adjustments,

the linear trend rose

to 0.044 deg C/decade.

Thanks to Anthony Watts

who provided the link to the

older GISTEMP data archived

at John Daly’s website

in his post here:

NOTE:

Bob,

The credit really should

go to Michael Hammer,

who wrote that post,

but I’m happy to have

a role as facilitator. –
