In the past couple of years, in the northeastern United states, I've noticed that we will have temperatures in the 70s in October and November, and temperatures below freezing in March-April. Is this an effect of global warming? I don't know how it is in the Southern Hemisphere but could they be getting colder during their summer months and warmer during their winter months? In a hundred years could it flip flop and see snow in June and "summer" vacations in January? Or is there just some weird weather patterns associated with el nino/nina, ect...?
Warmer winters and cooler summers effects of global warming?
That is just weather. If that pattern was part of climate you would be seeing it all over the northern hemisphere and it would be indicated that we were entering an Ice Age. Other parts of the U.S. are following different weather patterns that give the cold winters and warm summers.
Reply:Most of the temperature increases anticipated from global warming are from raising the coldest days by a couple degrees. There is more warming on the colder days and nights. Global warming alarmists seldom admit this because obviously that turns their theory into Global Moderation and their purpose is to propose gloom and doom and blame it on human activity.
Reply:Mostly it's just weather.
You can't say much about global warming by looking at "the past couple of years" in a relatively small location. You need to analyze many years of data over a widespread area.
That said, weather systems are fueled by heat. More heat means stronger weather systems of all kinds.
"Impacts due to altered frequencies and intensities of extreme weather, climate, and sea level events are very likely to change."
