NASA HAD MEASURED EARTH’S TEMPERATURE AT 15 C (59 F) IN 2004.
As you can see in this NASA publication, NASA had Earth’s Average Temperature at 15 C in 2004. However, the global average temperature recorded by NOAA was 14.44 C, 0.54 C above the 20th century long term average 13.90 C. This deviation positioned 2004 as the warmest year on record according to NOAA.

It’s Interesting how much information we have on the other planets, but also the gaps of information we don’t have as shown in the 2004 Planetary Fact Sheet.
Earth’s Temperature…
Mean Temperature (C or F) – 15 C (59 F) This is the average temperature over the whole planet’s surface (or for the gas giants at the one bar level) in degrees C (Celsius or Centigrade) or degrees F (Fahrenheit). For Mercury and the Moon, for example, this is an average over the sunlit (very hot) and dark (very cold) hemispheres and so is not representative of any given region on the planet, and most of the surface is quite different from this average value. As with the Earth, there will tend to be variations in temperature from the equator to the poles, from the day to night sides, and seasonal changes on most of the planets.
Did you know this stark difference between the planets?
Axial Tilt (degrees) – The angle in degrees the axis of a planet (the imaginary line running through the center of the planet from the north to south poles) is tilted relative to a line perpendicular to the planet’s orbit around the Sun.
*Venus rotates in a retrograde direction, opposite the other planets, so the tilt is almost 180 degrees, it is considered to be spinning with its “top”, or north pole pointing “downward” (southward). Uranus rotates almost on its side relative to the orbit, Pluto is pointing slightly “down”. The ratios with Earth refer to the axis without reference to north or south.

Record warm intensified in early 1998
WASHINGTON, June 8 UPI– After the past several years of record warm
temperatures worldwide, the first several months of 1998 brought some of
the warmest U.S. temperatures ever on record, the federal government
announced. The data was collected by the National Oceanic and
Atmospheric Administration and announced by Vice President Al Gore,
who said some of this year’s warming could be attributed to the cyclical El
Nino patterns. But, Gore said, the overall trend found by NOAA ‘is a
reminder once again that global warming is real, and that unless we act, we
can expect more extreme weather in the years ahead.’ He cited such events
as record levels of precipitation, record deaths from tornadoes, damage to
coral reefs from the Florida Keys to Australia, and wildfires in Malaysia,
Brazil and Mexico. Gore announced the NOAA findings as a means of
increasing pressure on Congress to approve President Clinton’s budget
request for $6.3 billion over five years for tax and research incentives to
promote more energy- efficient products and technologies. Gore insisted
U.S. industry had the expertise and ability to make affordable changes to
combat global warming, saying, ‘We can do that. We know how to do that.’
Worldwide average temperatures in the 1980s and the 1990s have been the
highest on record, and the Earth’s average surface temperature last year of
some 62 degrees Fahrenheit represented the highest level ever recorded.
