Global cooling wrote their 1971 paper, climatologists had not yet recognized the significance of greenhouse gases other than water vapor and carbon dioxide, such as methane, nitrous oxide, and chlorofluorocarbons. Early in that decade, carbon dioxide was the only widely studied human-influenced greenhouse gas. The attention drawn to atmospheric gases in the 1970s stimulated many discoveries in subsequent decades. As the temperature pattern changed, global cooling was of waning interest by 1979. A common argument used to dispute the significance of human caused climate change, which TIME Magazine calls the Ice Age Fallacy, is to allege that scientists showed concerns about global
Emissions Trading Scheme in South Korea in the scheme: Carbon Dioxide, Methane, Nitrous Oxide, Hydrofluorocarbons, Perfluorocarbons, and Sulfur hexafluoride. More than 525 business entities are subject to the ETS with specific emission targets set for each sectors. Similar to that of the European Union, South Korea has divided its emissions trading scheme into three phases. With differing time spans and targets within each phase. The country is currently in its first phase which started in 2015 and lasts until 2017. The second phase occupies a 3-year-span from 2018 to 2020 and the final third phase is from 2021 to 2025. During Phase 1 all permits will
