Scientists may have solved mystery of rapidly rising Indian Ocean sea level
Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades.
The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.
A new study in Geophysical Research Letters, a journal of the American Geophysical Union, uses climate and sea level data from the past several decades to connect the Indian Ocean’s sea level rise to its changing monsoon circulation…More

Featured Special Collection
The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer. This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census. The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years. The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades. The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
