Agreed, I think there's bigger problems than mild warming. As far as I can tell, mild warming is usually good for the human race and for ecological health, such as plant growth.
For example, leaf area index has increased by 8% since the 80s. CO2 is fertilizing plant growth.
This is a common denialist point and is unfortunately a massive oversimplification, there is a hard limit to this increase. Plants are limited by far more than co2
