Note: The data presented in this report are preliminary. Ranks and anomalies may change as more complete data are received and processed. Effective September 2012, the GHCN-M version 3.2.0 dataset of monthly mean temperature replaced the GHCN-M version 3.1.0 monthly mean temperature dataset. Beginning with the August 2012 Global monthly State of the Climate Report, released on September 17, 2012, GHCN-M version 3.2.0 is used for NCDC climate monitoring activities, including calculation of global land surface temperature anomalies and trends. For more information about this newest version, please see the GHCN-M version 3.2.0 Technical Report.
*The GHCN-M version 3.1.0 Technical Report was revised on September 5, 2012 to accurately reflect the changes incorporated in that version. Previously that report incorrectly included discussion of changes to the Pairwise Homogeneity Algorithm (PHA). Changes to the PHA are included in version 3.2.0 and described in the version 3.2.0 Technical Report. Please see the Frequently Asked Questions to learn more about this update.

- Global average combined land and sea surface temperature was
the second warmest on record for June
- January-June 2002 global temperature was the second warmest
such 6-month period on record
- June temperatures were 3-5°C (5.4-9°F) warmer than
average over much of Europe, eastern Asia and parts of the
- Above average precipitation during June occurred across parts
of interior China and Europe, with drier than average conditions
observed from the Philippines, Taiwan and across much of Japan

anomalies calculated from the Global Historical Climatology Network
data set of land
surface stations using a 1961-1990 base period also show the
warmer than average temperatures across much of the United States,
Europe and the Mediterranean region and much of eastern Asia.
Cooler than average temperatures were observed over much of Chile
and Argentina .
- For June 2002, the global average land and ocean surface
temperature was 0.50°C (0.90°F) above the 1880-2001
average, ranking as the second warmest June on record
- The warmest June occurred 4 years ago during the last El
- The June land surface temperature average was second warmest on
record, 0.75°C (1.35°F) above average
- Globally averaged ocean surface tempeatures were 0.39°C
(0.70°F) above the 1880-2001 mean, or third warmest
- The global land and ocean surface temperature average
(January-June 2002) was the second warmest such 6-month period in
the 1880-2002 record, 0.64°C (1.15°F) above the long-term
mean and 0.05°C (0.09°F) cooler than during the El
Niño year of 1998
- However, land areas
were warmest on record for the 6-month period from January-June
2002, or 1.14°C (2.05°F) above the 1880-2001 average
- Serial monthly global surface temperature departures with
respect to a 1971-2000 mean are shown in the figure to the
- The recent return to record or near record temperature
departures is evident, and globally averaged surface temperatures
(land and ocean) have been warmer than the 1971-2000 average for
the last 74 consecutive months
- During June 2002, much above average precipitation fell across
interior China, parts of Europe and across Micronesia
- Drier than average weather prevailed across coastal China, the
Philippines, Taiwan and Japan, as well as parts of the central and
western United States
