He did offer a solution. 

If you are so concerned about the environment and "climate change", don't use air conditioning, don't eat meat, don't own a dog.  

By the way, I have debated numerous climate change advocates - none of them have integrated solar, wind, geothermal, etc. systems. Very few have taken advantage of offers by utilities to do a home audit and provide a list of steps that can be done to make a home more energy efficient.  Most have done nothing to make their home or offices more energy efficient such as replacing all bulbs with LED, adding insulation, more energy efficient appliances, etc. Most, but not all of the climate change advocates, don't drive electric cars.  

Most climate change advocates are complete hypocrites.
