Once it's added to the atmosphere, it hangs around, for a long time: between 300 to 1,000 years. Thus, as humans change the atmosphere by emitting carbon dioxide, those changes will endure on the timescale of many human lives.
Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis. These dynamics make restoring and managing existing forests, and adding trees to ecologically appropriate lands outside of farmland, especially important
87 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil.
The largest human source of carbon dioxide emissions is from the combustion of fossil fuels.
Its not too late but we are in effective closing the window of opportunity to achieve this.
