Warming has occurred in both land and ocean domains, and in both sea surface temperature (SST) and nighttime marine air temperature over the oceans. (ipcc.ch)
Increasing the surface temperature over the ocean by 1 °C should increase the humidity of saturation and thus the absolute humidity by 8 percent. (desmogblog.com)
Let's compare the warming and cooling patterns for lower troposphere temperatures over the oceans to a spatially complete, satellite - enhanced sea surface temperature dataset, Reynolds OI.v2. (wattsupwiththat.com)
