The weight of air above you is decreasing, you are being affected by an atmospheric cyclone, OR you are climbing up a mountain.
I don't have real-time data on barometer readings. You can check your local weather forecast or a weather website for up-to-date information on barometric pressure readings for your area.

the answer is yes
Yes, temperature changes can impact the accuracy of a barometer. Temperature variations can cause the air pressure inside the barometer to change, affecting its reading. It is important to calibrate the barometer regularly to account for temperature changes and ensure accurate readings.
Pilots adjust a barometer to ensure it reflects the current atmospheric pressure at their location, which is essential for accurate altitude readings. Since atmospheric pressure decreases with altitude, an uncalibrated barometer could lead to incorrect altitude estimations, potentially resulting in unsafe flight conditions. By setting the barometer to the local pressure, pilots can maintain precise altitude awareness, enhancing safety and navigation accuracy.
The air will become lighter causing the barometer to fall. the opposite will occur for cold air.
Yes, humidity can affect the reading of a barometer because changes in humidity can also impact air pressure. Moist air is less dense than dry air, which can cause slight variations in the barometer reading. It is important to account for humidity levels when interpreting barometer readings accurately.
dont break it
it goes up. :D
Nothing
The height of the mercury column is used to measure atmospheric pressure. If the barometer is also subjected to high temperatures, the thermal expansion of the mercury column will indicate a higher pressure than is really the case. This will make the barometer readings useless.
