Add water to the boiler. You should have an automatic pressure reducing water make up valve, somewhere near the boiler. If it feeds directly into the boiler, make sure the boiler is cool when you add. Normal pressure on a cool boiler should be around 12 psi. The pressure will rise as the water is heated. You need a minimum of 1/2 psi for every foot of rise in the loop. So 12 psi in the basement will allow most systems to have a rise of appx 24 feet to the highest strip of baseboard. Remember, the pressure relief valve on the boiler lifts at 30 psi, so you need to stay well below that when the boiler is up to temperature.
The seas would rise.

Global warming simply means an increase in atmospheric temperature on a global level. One significant effect effect of this temperature rise is the melting of our polar ice caps, which will eventually result in a rise in sea level.

critical boiler operating steam parameter 221.12bar and 375 centigrate . you can rise in pressure and temperatureabove the critical point. that is called supercritical boiler.
An economizer is used to heat boiler feedwater up closer to the temperature of the boiler water, using heat from the boiler exhaust gases, heat that would otherwise be wasted. The main reason is to improve the efficiency of the boiler. For every 44 degree F drop in exhaust gas temp. there is an 11 F rise in feedwater temperature and a 1% gain in boiler efficiency.
High Rise was created in 1975.
So the steam can rise from the boiler to the hot water tank storage
Heat can cause air to rise :)
Typical heating boiler setpoint is around 180*, if you are looking to economize, look into having a reset control installed. The reset control will adjust the boiler setpoint based on outdoor air temperature. On a 70* day you would have 70* boiler water temp with a reset schedule of 1.5, for every degree outdoor temp drops below 70 the boiler temp would rise 1.5* so on a 0* day, boiler temp would be 175*. The reset schedules are adjustable.
It is a condominium community with units in a high-rise building.
High Rise Bridge was created in 1972.

The enhanced greenhouse effect is making air temperatures rise.
