Geography of New Zealand are generated by greenhouse gases, mainly methane and nitrous oxide, which come from farming and agriculture. Organisms that grow inside of grazing animals' stomachs turn New Zealand's grass into methane. The increase of carbon dioxide in the air helps the plants to grow faster, but the long-term effects of climate change threaten farmers with the likelihood of more frequent and severe floods and droughts. Growers of kiwifruit, a major export in the horticulture industry of New Zealand, have experienced difficulties as a result of climate change. The recent warm winters are not providing the adequate cool temperatures needed for the
Greenhouse gas emissions in Kentucky tons of perfluorocarbons (PFCs) (4.8 MMTCE), and 0.003 million metric tons of nitrous oxide (0.2 MMTCE) The major source of carbon dioxide emissions was fossil fuel combustion (96%), the majority of which is utility coal. Minor emissions came from cement and lime production and forest/grassland conversion. Carbon dioxide sinks (i.e., an increase in forest carbon storage) offset about 26% of the total carbon dioxide emissions. Sources of methane emissions were coal mining (73%), domesticated animals (12%), landfills (10%), manure management (3%), and natural gas/oil extraction (2%). Nitrous oxide emissions were from fertilizer use. Sources of perfluorocarbons were HCFC-22 production (91%)
