Richtig. Nur, dass es beim natürlichen Klimawandel ein sehr langsamer Prozess war und die Vegetation ausreichend Zeit hatte, sich umzustellen. Der menschengemachte Klimawandel läuft erdgeschichtlich so schnell ab wie kein anderer vorher.

Dass das nicht richtig ist, ist wissenschaftlicher Konsens. Nur mal zwei Beispiele:

The last glacial period was terminated by an abrupt warming event in the North Atlantic approximately 15,000 years before the present, and warming events of similar age have been reported from low latitudes. Understanding the mechanism of this termination requires that the precise relative timing of abrupt climate warming in the tropics versus the North Atlantic be known. Nitrogen and argon isotopes in trapped air in Greenland ice show that the Greenland Summit warmed 9 +/- 3 degrees C over a period of several decades, beginning 14,672 years ago.

The Younger Dryas (YD) was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP).[2] It is primarily known for the sudden or "abrupt" cooling in the Northern Hemisphere, when the North Atlantic Ocean cooled and annual air temperatures decreased by ~3 °C (5.4 °F) over North America, 2–6 °C (3.6–10.8 °F) in Europe and up to 10 °C (18 °F) in Greenland, in a few decades.[3] Cooling in Greenland was particularly rapid, taking place over just 3 years or less.[1][4] At the same time, the Southern Hemisphere experienced warming.[3][5] This period ended as rapidly as it began, with dramatic warming over ~50 years, which transitioned the Earth from the glacial Pleistocene epoch into the current Holocene.[1]
Das bedeutet natürlich nicht, dass so ein Klimawandel nicht katastrophale Folgen auf das Leben des Planeten hat.
