metta8 saidPOTUS Signs Executive Order to Cut Govt. Greenhouse Gas Emissions by 40%
That won't really make much difference.
China already emits more greenhouse gasses than the U.S. Even if the U.S. eliminated emitting all greenhouse gasses, it would not be sufficient since emissions by other nations are increasing.
In addition to drastically reducing greenhouse gas emissions, we will need to help other nations to do the same whether we think it is our responsibility or not. It is unlikely that that can be done without drastically increasing nuclear power considering that by the year 2100, probably global demand for power will increase by about four times as poor nations increase power generation to lift their people out of poverty. About 90% of that power will have to come from non-CO2 emitting sources. That includes power for heating, cooling, lighting, cooking, transportation, manufacturing, etc.
Actually, I doubt that CO2 emissions will be reduced sufficiently the reason being that there is inadequate commitment. The resulting climate changes, which have already begun, are likely to cause serious damage to governments and civilizations.
