Homeowners interested in installing a gas fireplace may need to have a gas line installed. The cost of this can range from nothing, in cases where the gas company installs a line for homeowners purchasing new appliances, to as much as $1,000 for professional installation on a complex project, according to CostHelper.nother conversion method uses top-vented gas fireplace inserts, which may include fans and thermostats. These cost from $1,200 to $2,900, plus another $600 to $1,000 for professional installation.
Latitude Affects Temperature. One of the primary factors affecting the unequal heating of the Earthâs atmosphere is latitude. Latitude is the measurement of the distance of a location on the Earth from the equator. The further away from the equator that a location resides, the less sunlight that this location receives.
The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6Â° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years.Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.By the beginning of the 21st century, Earthâs temperature was roughly 0.5 degrees Celsius above the long-term (1951â1980) average. (NASA figure adapted from Goddard Institute for Space Studies Surface Temperature Analysis. ).limate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sunâs energy varied. But in the past century, another force has started to influence Earthâs climate: humanity.
