Nothing to be worried about. The planet has seeped methane into vast volumes into the atmosphere since before life appeared for the first time. Yes, you read that right. We have found methane on most planets and many moons and they have no proven life so where did this come from? Where did the methane in interstellar space come from? A process called serpentinization produces abiotic methane deep inside Earth between the mantle and the cust. The atmosphere has a powerful mechanism to deal with it quickly. Thats why it’s still measured in parts per billion. Those methane seeps are not big or worrisome. They were always there – we just did not see them before.
