  • If by 'sea' you mean all of the bodies of saltwater that have connections to the oceans, then no, the 'sea' is not getting more salty. In fact, it is becoming more diluted as glaciers melt and retreat during a period of global warming. During a period of global cooling, glaciers will form and the 'sea' will become more salty. Any body of water that does not drain into the ocean, such as the Great Salt Lake in Utah, is becoming more salty. Again, this is due to warming. This is similar to letting a pan of saltwater sit in the desert during the summer--the water will evaporate leaving salt crystals such as Halite on the bottom of the pan. If the 'dam' between the interior basin and the ocean is breached, then an influx of saltwater will rush over the salt deposit--this has happened in the Mediterranean over millions of years where the Straight of Gibaltrar was the 'dam.' As for too salty to support life, I would not know because I am not a marine biologist.
