The real issue is this. The northern hemisphere is shattering cold and winter records (record cold in Siberia and snowfalls in Russia). Whereas the southern hemisphere is setting record summer temperatures (Australia).
Seems to me, the Earth's atmosphere isn't protecting us like it use to. In other words, we aren't as insulated as before. The heat is released in the winter and the heat is let in during the summer.
And in between, the weather between these two extremes is becoming more extreme.
Do I believe we can do anything about it, no. So I am not worried.
