What was the climate during the silurian period?

During the middle silurian the climate was much warmer, it was though of as a period where the climate became more stable, ending the previous pattern of random climatic fluctuations. A new greenhouse phase began, leading to a rise in global sea level form ice melt. However, in coastal areas where there was warm shallow waters, the conditions led to large evaporite deposits, although this was largely exclusive to equatorial regions. In this instance, plants that had lived in water had to adapt to life on land or die off.
