Basically nothing. It seems like a lot of methane, but on a global scale it's a drop in the bucket.
However, it's a sign of melting permafrost on a wide scale that is releasing methane, and that does have an impact which will get more pronounced.
Because methane is more potent a greenhouse gas than CO2, there's a risk of a runaway feedback cycle melting more permafrost and releasing more greenhouse gases. And that's not thinking about the colossal amounts of frozen methane on the sea floor which is quite sensitive to temperature changes. We're playing with fire here, sorta literally.
