The last two years have seen significant progress in investigating trends in the mesosphere, thermosphere and ionosphere but also some new puzzles have been created. Important part of the progress is finding that the CO2 trend in the lower thermosphere is remarkably higher than expected. Also new information on some other experimental trends helped to improve the global trend scenario and our understanding of long-term trends in the upper atmosphere. Significant progress have been reached in modeling the long-term trends; in some parameters the agreement with observed trend sis now not only quantitative but also qualitative. All that will briefly be reviewed.
