The Long Timescales of Human-caused Climate Warming: Further Challenges for the Global Policy Process.
Focus group 1: Climate Change Science by Jerry Mahlman.
Jerry Mahlman describes “global warming dilemma,” as an effective consensus, that are immediate and aggressively takes steps required to avoid climate changes. The stabilising of atmospheric concentrations of carbon dioxide needs 60%-80% permanent reduction.
Understanding the changes in Earth’s atmospheres long lag response suggests a stringent scenario, which is insufficient to prevent moderate temperature increases.
Based on Mahlman’s scientific reading, he concludes that deferring action until climate change has broadly recognised deleterious effects that are likely to lock in profound environmental impacts, for centuries.
Today’s greenhouse gas emissions use up the Earth’s assimilative capacity. This increases the length of time that greenhouse gases remain in the atmosphere.
What makes climate change an issue of intergenerational fairness present in society’s willingness to bear significance to economic costs? Protecting future human and animal generations from catastrophic environmental harm. Human activities affect global environmental change and William Schlesinger examines potential employment for land-use and land-use change as a technique for removing carbon dioxide, from the atmosphere.
Presently, fossil fuel consumption emits approximately 6 billion tons of carbon into the atmosphere, on an annual basis. Schlesinger traces the physical and biological processes; carbon dioxide is transferred to oceans, biomass and terrestrial and marine sediments. Reforestation success could significantly reduce the timescale of climate change by up to 10%.
Present forecasts suggest that carbon dioxide emissions will rise to 15 billion tons a year by 2050. Schlesinger acknowledges potential technologies that could possibly capture carbon dioxide.
