Imagine if earth’s temperature stayed steady at very high or very low temperatures all year around everywhere in the world. That wouldn’t be climate change,would it? It would give plenty to be worried about, though.
Or imagine if our Modern Warm Period is no different from the Medieval Warm Period or the Roman Warm Period (time of Jesus) or the Minoan Warm Period (pretty much Era of Judges from Moses to Samuel)?
That's the reality I'm looking at.
