Why did the green communities change the term from global warming to climate change?

I'm not sure the term has changed, so much as two different terms describing slightly different things - which one gets used in headlines perhaps changes as per fashion. To me global warming is the nett effect of the planet trapping slightly more energy from the sun than previously. Climate change is the consequence of that - perhaps local warming - perhaps local cooling (if say the gulf stream shifts direction a little and we end up with a climate more appropriate to our latitude) - more frequent and/or violent storms, greater swings in weather patterns (drought vs flood), sea level rise and so on.

 

Simply because the climate DOES change by the second?

Somewhere on the planet it is daytime, somewhere it is night time, somewhere it is raining, somewhere it is snowing, somewhere it is sunny, somewhere it is winter, somewhere it is summer.

No that's still weather, not climate. (possibly other than the day/night thing). The distinctions are meaningful - you wouldn't say that the tides of the sea can't be happening because waves continually move up and down anyway, or land can't be sinking because the tides go up and down.


Sometimes the doomsayers turned out to be right - remember Churchill's predictions before WWII?
