I guess they’ll tell us how high the sea level has risen in another article.


Screenshot makes it look like an orbital laser glassing the planet.


The real proof will be when we start to see the value of beach front property plummet.


The data it sends back is just a text file that reads “oh no oh no oh no oh no…”


>Two streams of data from Sentinel 6 are now available to the global weather forecasting community, providing information about the sea surface height with accuracies of 2.3 inches (5.8 cm) and 1.4 inches (3.5 cm) respectively. The first data stream is available immediately upon acquisition. The second is released two days later after additional processing. Later this year, even more precise data sets, accurate to 1.2 inches (2.9 cm), will be released to climate researchers, NASA and ESA said in their statements. ​ Its my understanding that tide gage measured sea level rise is about 0.2~0.4cm/year, including various corrections. 2.9cm accuracy is 10x the thing we are trying to measure. What am I missing?
