Even if the globe is warming, what makes you believe that your area won't get even colder? Global warming refers to an average...an average in a distribution that is likely to exhibit greater variance toward extremes, too.

Global warming refers to an average...an average in a distribution that is likely to exhibit greater variance toward extremes, too.

Please state sources for that greater "variance" claim. Is it:

Man caused
El Niño/La Niña
Milankovitch cycles
Variations in any of the Hadley/Ferrel/Polar cells
Sun spot activity like the Maunder Minimum
Maybe another Mount Tambora.

BTW, it's global average temperature.

Global warming is what the sun does to the earth. Stand in front of a fire and you have mammal warming.
The extremes should be taken with a grain of salt. The records aren't as reliable before 1850, but they still pale in comparison to today's equipment. 1850 had 1.2 billion people. Less dispersion and less equipment.
Thermometers were manual back then and required someone to monitor it. Now we can do that remotely and mark the lowest temperature. There are also far more scientific minded people to record data.

FYI the temperature increase in the last Century (or Millennium) is an ESTIMATE:

The Intergovernmental Panel on Climate Change (IPCC) concludes:

"The best estimate of global surface temperature change is a 0.6 °C increase since the late 19th century with a 95% confidence interval of 0.4 to 0.8 °C"
