You may be experiencing an unusually cold day where you live–that is irrelevant. The issue is the pattern that has emerged when looking at GLOBAL AVERAGE temperatures taken over many, many years. That being said, extreme storms and unusual weather phenomena are completely consistent with the climate change model.
The global average temp has increased 1-2 degrees in the past century, and the trend is exponential, not linear. A relatively small change in global ave. temp. can have a significant impact on regional climates, as we have witnessed during the past few years.

While it is true that climate shifts have taken place naturally in earth’s history, the alarmingly atypical factor in the current trend (beginning at the dawn of the Industrial Revolution and especially during the past few decades) is the RATE at which average global temperature (and atmospheric CO2 concentration) increase is happening — measurably faster than anything previously measured in ice core or geological/mineralogical samples that provide evidence of past climates.

Record heat waves. Record flooding. Record blizzards. Record tornados. Record droughts. Record wildfires. Record permafrost thaws and ice sheet melting.

Welcome to the new normal.
