It is happening, but the majority of fools dont really understand the concept of it, so make fun of it.
Global warming affects climates (long term trends), not weather (daily ups and downs). Huge hunks of Alaskan permafrost are being thrown into the ocean, just from a slight rise in average climate temperatures. The world is dumping CO2 into the atmosphere are rates comparable to the super volcanoes from the last mass extinction.
Honestly, it's disgusting how advanced our technology is, but we still allow our fossil fuel "dependance" to cripple us. Solar power is nothing new. It was developed in the 1800s. Using flowing water and wind as power sources are even older technologies. These methods are available and more efficient, yet the we stubbornly continue to rely on combustion.
