The major bergs that came free from the Ross ice shelf have substantially disintegrated over the last month.
This doesn't raise ocean levels since this ice was already floating. They don't say if this is related to the active volcanos under the West Antartic ice field or if its due to the warmer weather in the area.

Fairly heavy cloud cover has been evident over much of Central America for about two weeks. From the reduced number of heat signatures (red) in the later images, It appears that the cloud clusters have provided some much needed rainfall. The reduction in the number of heat signatures is especially noticeable in northern Guatemala and adjacent areas in Mexico.
