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.
(For more information, see Global Warming: Potential Effects of Global Warming) 1  Changes in climate not only affect average temperatures, but also extreme temperatures, increasing the likelihood of weather-related natural disasters. If global climate change causes the global average temperature to rise (top), there will be less cold weather, and a greater probability of hot and record hot weather. An increase in temperature variability will extend the extremes of temperature, both cold and hot. An increase in average temperature combined with increased variance will have little effect on cold weather, but hot weather will be more common and record hot weather will increase greatly.
