Methane bubbles are coming up from ocean vents off the Washington and Oregon coast, and a new study
identified warming ocean temperatures one - third of a mile below the surface as likely responsible.

The researchers
identified several key circulation patterns that affected the winter
temperatures from 1979 to 2013, particularly the Arctic Oscillation (a climate pattern that circulates around the Arctic
Ocean and tends to confine colder air to the polar latitudes) and a second pattern they call
Warm Arctic and Cold Eurasia (WACE), which they found correlates to sea ice loss as well as to particularly strong winters.
Kosaka and Xie made global climate simulations in which they inserted specified observed Pacific
Ocean temperatures; they found that the model simulated well the observed global
warming slowdown or «hiatus,» although this experiment does not
identify the cause of Pacific
Ocean temperature trends.
Considering all the short - term factors
identified by the scientific community that acted to slow the rate of global
warming over the past two decades (volcanoes,
ocean heat uptake, solar decreases, predominance of La Niñas, etc.) it is likely the
temperature increase would have accelerated in comparison to the late 20th Century increases.
Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global
warming has also been
identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface
temperatures in the northern Pacific
Ocean.4
