what you are describing is bio-diversity collapse. . .
The effect on climate is more about humans creating a bigger solar radiation heat sink by replacing green areas with steel, asphalt and concrete, which absorbs and retains heat and is capable of raising the local temperature significantly
As far as climate change, the earth has been warming for at least 10,000 years since the last ice age, though there were no thermometers back then. . however the thermometer with a standardized scale is only about 200 years old, so there's a bit of excessive extrapolation going on as a mind game using fear. .
