Are clean burning gas, and EV's on the current grid enough? Co2 and pollution for that matter is still being spewed in the atmosphere. What is the break even rate for the Earth to absorb co2 as fast as we emit it? As it stands we're at 400ppm co2 and counting.

Short answer, no. Nothing we have done so far is enough to reverse global warming. Humans have not even managed to stop global co2 emissions from increasing each year.
It doesn't help that the global population will continue to grow, requiring more and more electricity, land, and resources. As deforestation and development of the world continues, the earth has less ability to un-do the changes we have made.
Vehicle emissions are only a small fraction of total global co2 emissions. Energy production is the leader, and forecasts by the EIA show that fossil fuel will remain the same and even grow (natural gas) as an energy source through 2040. Renewable energy is expected to grow, but not replace any other energy forms.
