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.

Most policymakers concerned about global warming have in mind some ultimate objective for limiting the amount of projected climate change, or atmospheric carbon dioxide (CO2) accumulations.

Although some researchers have raised concerns about possible negative effects of rising CO2 on ocean surface pH, there are several lines of evidence demonstrating marine ecosystems are far more sensitive to fluxes of carbon dioxide from ocean depths and the biosphere's response than from invasions of atmospheric CO2.

That lack of immediate concern may in part stem from a lack of understanding that today's pollution will heat the planet for centuries to come, as explained in this Denial101x lecture: So far humans have caused about 1 °C warming of global surface temperatures, but if we were to freeze the level of atmospheric carbon dioxide at today's levels, the planet would continue warming.
