The University of Alabama-Huntsville manages a satellite system that measures global temperature. These measurements are much better than the land based measurements because the satellites cover more of the Earth’s surface and are not subject to the typical errors that plague land based measurements systems. The satellite system has been in operations since 1979.
The oceans represent about 3/4ths of the Earth surface. The land based do have some ocean temperature measurements but nothing like the satellite coverage. The raw data from the land based measurements are mostly readjusted by the managers of those systems. This could be an invitation to make the final numbers come out to satisfy your biases.
The June 09 numbers show decline in the temperature anomaly. It is consistent with the downward trend of global temperatures in this decade.
