Correcto!! Global warming is out. Those who would control language and thus minds now refer to "climate change".
You’re right. I have heard the term “climate change” more lately than glowball warning. Climate change is more generic and more open to interpretation. And, of course, climate change happens every season. A century from now carbon emissions will doubtless be blamed for summer slowly changing to winter. Lets face it, there is nothing climate change can’t do!
