But when the best scientists are surprised, you can bet some propaganda has been dropped on the trail to throw them off.
In that regard, some specialists on methane which is a green house gas, were dangerously surprised:
"Our survey was designed to work out how much methane might be released by future ocean warming; we did not expect to discover such strong evidence that this process has already started."(Science Daily). In other words they were preparing for a future catastrophe when they ran upon the evidence that the catastrophe is already here in the making.
There are two immediate negative considerations.
One consideration is that this could mean that efforts of the major nations to cut down on green house gas emissions have been neutralized, and that far more must be done even to get to where we thought we were, because methane "released from gas hydrate in submarine sediments has been identified in the past as an agent of climate change".
A second consideration is that "methane dissolved in the seawater contributes to ocean acidification", and as a recent post here shows, food supply is endangered because the ocean around Alaska is showing increased acidification.
The surprise in this matter may be a larger surprise than the scientist first suspected, since "July was the hottest the world's oceans have been in almost 130 years of record-keeping."
