Glacier Retreat Began Before Industrial CO2

He points to a crucial detail in the timeline: species decline and a massive meltwater pulse both occurring around 14,600 years ago. To melt ice that rapidly, you need a significant energy input from somewhere. That raises fundamental questions about what was driving these changes. He then draws a parallel to modern glacier retreat, noting that glaciers began shrinking well before the industrial revolution, at least 75 to 100 years before significant carbon dioxide was introduced into the atmosphere. The implication is clear: if glaciers were already retreating before industrial CO2 emissions, then other forcing mechanisms must be at work. This isn't climate denial. It's asking what the actual drivers are and whether we're accounting for all of them.
