Make no mistake, global sea level rise is accelerating faster than ever. Previous estimates based on satellite data may have suggested that sea level rise was actually slowing down over the last couple decades, but according to a new Nature Climate Change study, measurement errors may have concealed the ongoing acceleration.
Beginning in 1993, a groundbreaking satellite-era time series described one of strongest and most robust signs of climate change: global mean sea level rise. It used radar observations of sea surface height from three consecutive satellite altimeter missions: TOPEX/Poseidon, Jason-1 and OSTM/Jason-2. According to this seminal climate record, sea level rise was lower in the past decade than during the decade before — which would totally be good news, if only it was true.
