it is so insignificantly low that it isn't even a concideration I'm afraid. it's about 2.3% over the entire' industrial age' If I got my facts right- natural cuases such as methane gas from poopin cows, volcanos, undersea emissions from natural vents etc make up the rest- 98% - so, unless we can stop the 98% natural causes, we aint gonna do squat to 'reverse the trend', but yet it will cost us many hundreds of billions of dollars tackling the 'human element'- AND we don't even know what kind of effects it will have should we actually be able to despite insurmaountable odds against it- should the earth cool down again it will wipe out so many species that have adapted to life in the warm lane, that we'll be responsible for mass genocide- The environuts will ALWAYS have somethign to complain about in regards to evil man and his selfish desire to flourish until the return of the Lord
You don't have your facts right. The primary cause of the increase in atmospheric CO2 concentration since the mid-1800s is human activities (this is easily verifiable via multiple methods). This increasing atmospheric CO2 will affect Earth's radiative balance, and altering Earth's radiative balance will affect climate. Though there are possible feedback scenarios that could cause a cooling trend, there is no indication that such feedbacks are operation to counter the warming trend that is caused by the alteration of Earth's radiative balance caused by increasing atmospheric CO2.
How much of the recent CO2 increase is due to human activities?
How do we know that recent CO2 increases are due to human activities?
