IF the increase of CO2 was coming from natural causes then we certainly would be in the midst of tremendous climate change.
Fortunately it is not, we have put most of it there ourselves.
CO2 is more of a symptom than a cause. Yes, there will be some warming of the atmosphere (1C/doubling) and a change in the relative amounts of energy taking the various pathways out to space, but nothing like the doomsday scenarios presented by the Warming Alarmists.
What we are seeing today in extreme weather events is the result of the GHG levels of about 30 years ago. As the years go on, and the affects of the rapid rise to 400+ ppm for CO2 and 1850 ppb for CH4 kick in, how long before we are losing ground on repairing our infrastructure just from extreme weather events? How many tens of thousands of homes damaged or destroyed in the hurricanes, floods, and fires of 2017, just in the USA? How much damage to the infrastructure, power, water and sewage, by these events? How much damage are we going to see from the present intrusion of Arctic air on the East Coast?
Not doomsday, but serious damage to our nation and standard of living.
