Answer:
Siberia
Step-by-step explanation:
The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050 mbar with record highs close to 1085 mbar.
NOTE: mbar = Millibar, the unit of air pressure in the metric system, commonly used in meteorology, equal to 100 pascals, 1,000 dynes per square cm (about 0.0145 pounds per square inch), or slightly less than one-thousandth of a standard atmosphere.
