A doubling of atmospheric CO2 hasn't significantly impacted global temperatures on average.
Carbon emissions have had a minuscule impact on climate change; whereas, the Green New Deal's impact on climate change would be too insignificant in order to justify its cost.
As I've previously noted, there were 4,000 ppm of atmospheric CO2 during the Cambrian explosion of life on Earth; today there is approximately 400 ppm of atmospheric CO2, compared to approximately 200 ppm a couple of hundred years ago. (1)
Compared to current levels of atmospheric CO2, there was approximately ten times as much atmospheric carbon dioxide along with an abundance of life increasing in population on Earth millions of years ago. Plants need CO2 to live. Hence, carbon dioxide helps crops grow.
A doubling of atmospheric C02 has increased overall air temperatures by a mere 1 degree Celsius over the last few hundred years; this is hardly a need of grave concern. (2))

Cold weather kills more Americans than hot weather. So a bit of global warming from carbon emissions might be more beneficial for the United States of America as well as perhaps some other parts of the world.

I'd now also would like to take this opportunity to mention that climate change models have failed to accurately predict climate change. Hence, scientists yet have a lot to learn about climate change. its causes as well as its environmental impact.

The Green Energy Deal is a farce, because this unrealistically expects our nation to be totally powered with renewable energy within 10 years; that'd mean replacing 88 percent of our current energy production that's supplied from non-renewable sources of energy with renewable sources of energy like solar power and wind mills. I currently drive a Tesla electric powered car whose electric energy comes from nuclear power; half the electricity in my state of Illinois comes from nuclear energy. There's not enough space in urban areas for solar panels to supply our state's energy needs nor could wind-mill farms store enough electricity for providing our state's energy needs. So then, the Green Energy Deal fails to supply energy for electric cars that this deal mandates in replacement of cars powered by fossil fuel.
As I've previously noted, if atmospheric carbon dioxide around Earth were to become a grave concern, then please let's just simply have this CO2 transported to Mars. Transporting CO2 and other greenhouse gases from Earth to Mars might be more beneficial than the Green New Deal for Americans as well as for humanity's future on Earth and Mars.
