Vitamin A is the name of a group of fat-soluble retinoids, including retinol, retinal, and retinyl esters [ 1-3 ]. Vitamin A is involved in immune function, vision, reproduction, and cellular communication [ 1, 4, 5 ].
Along the region, the Atlantic Ocean is rising at an annual rate three times to four times faster than the global average since 1990, according to the study published Sunday in the journal Nature Climate Change.
Over the past 5000 years the average rate of sea level rise was much less than 1 meter per millennium (1 mm/year), as shown by geologic markers on coastlines. In the past century tide gauges at coastal cities reveal a larger rate of sea level rise. The second chart below shows that sea level rose about 2 mm/year during 1920-2000. Satellites began to measure sea level precisely in 1993. Since then sea level has been rising about 3.2 mm/year. This rate is equal to just over one foot per century. The impact of such sea level change is substantial, yet the concern is that far greater sea level rise will occur this century if the major ice sheets disintegrate.
