With the growing severity and frequency of storms, heat waves and wildfires, and the other dangers from climate change, there are many reasons to be concerned about the amount of carbon dioxide in the atmosphere. Scientists have shown that humanity's addiction to burning fossil fuels is causing this problem, which means it's time to kick that habit.
Because transportation generates more than one-fourth of the CO2 emitted by burning fossil fuels, slashing CO2 emissions requires phasing out vehicles powered by gasoline, diesel and natural gas.
