- Pro to the question "Is Human Activity Primarily Responsible for Global Climate Change?"
“[C]oncentrations of the two most important long-lived greenhouse gases, carbon dioxide and methane, have been increasing since the dawn of the industrial era; carbon dioxide alone has increased by about 40 percent. These increases have been brought about by fossil fuel combustion and changes in land use…
[G]lobal temperatures have been rising for roughly the past century and have so far increased by about 1.4 F. The rate of rise of surface temperature is… larger than any natural change we have been able to discern for at least the past 1,000 years.
Disputes within climate science concern the nature and magnitude of feedback processes involving clouds and water vapor, uncertainties about the rate at which the oceans take up heat and carbon dioxide, the effects of air pollution, and the nature and importance of climate change effects such as rising sea level, increasing acidity of the ocean, and the incidence of weather hazards such as floods, droughts, storms, and heat waves. These uncertainties are reflected in divergent predictions of climate change made by computer models…
But when the dust settles, what we are left with is the evidence. And, in spite of all its complexity and uncertainties, we should not lose track of the simple fact that theory, actual observations of the planet, and complex models – however imperfect each is in isolation – all point to ongoing, potentially dangerous human alteration of climate.”
