The article "Future CO2 Emissions and Climate Change from Existing Energy Infrastructure" by Steven J. Davis, Ken Caldeira, and H. Damon Matthews estimates the cumulative CO2 emissions and resulting climate change from existing energy infrastructure. The study projects that between 2010 and 2060, existing infrastructure will emit 496 gigatons of CO2 (gigatons of CO2), leading to a mean warming of 1.3°C above pre-industrial levels and atmospheric CO2 concentrations below 430 parts per million (ppm). The authors highlight that these emissions would likely avoid many key impacts of climate change, suggesting that the most threatening emissions have yet to be built. However, the expansion of CO2-emitting infrastructure will continue unless significant efforts are made to develop alternatives. The study also notes that China, with its rapidly expanding energy infrastructure, accounts for about 37% of the global emissions commitment. The authors conclude that overcoming infrastructural inertia and commissioning new, carbon-free energy sources are crucial for mitigating climate change.The article "Future CO2 Emissions and Climate Change from Existing Energy Infrastructure" by Steven J.
