why the weather is change so much in last 15 years?

Answer 1

Support your assertion. Convince us it changed. Where did it change? In many places, we can tell you why it changed. In most cases, we can't. A consistent global change is exceedingly difficult to prove.

Answer 2

You can't blame local variations on global warming - some isolated pockets have actually gotten cooler.

It is the in the basic nature of weather to be variable - meaning that it is ot reproducible from year to year. It is this fact that often leads to scientific arguments over whether global warming is real. Events like El Nino and La Nina add even greater variations.

That's why we report averages - whether temperature, snowfall, rainfall or hurricanes.

15 years is not enough time to conclude that the weather has changed. That's why records have been kept for 150 years. (And that may still not be enough time)

Answer 3

When changes in climate do occur, recorded history has often shown us that these changes happen very quickly when compared to era's of relative stability preceeding and following the period of change. All AGW hysteria asside, the climate is likely in a period of flux, thus the appearance of relatively rapid changes. Although, I personally have not noticed significant deviation in weather patterns where I live in the past 20 years or so of paying attention.

Answer 4

Because the weather goes through cycles.
