Thanks, it makes sense... I remembered some recent alarmists headlines about how lobsters will decline in the area due to warming but forgot that it was warming in the first place that made it the sweet spot it's currently.
Edit: anyway, production in the US has doubled in the last 20 years but the increase in global production is less than 50%. So it has not "exploded" in all the places where they catch them.
