Methane is responsible for a quarter of global warming that occurred since the 1850s, according to climate scientists.
Key findings of report
- Raising livestock, increase in coal mining, landfills, and oil and gas production were the specific activities linked to the greatest increases, according Global Carbon Project.
- Wetlands contributed the most of the emissions, at 30 per cent, while oil, gas and coal activities accounted for 20 per cent of the emissions. Agriculture made up 24 per cent of the emissions, while landfills were responsible for 11 per cent.
- Tropical regions in three continents Africa, Asia and South America were responsible for 64 per cent of the entire planet’s emissions, while temperate regions and the Arctic contributed to 32 per cent and four per cent respectively.
- Water-logged soil once it begins to thaw creates conditions ideal for methane production.
- Emissions increased nine per cent compared to the last decade.
- While methane emissions briefly stabilized between 2000 and 2006, concentrations of the gas in the atmosphere now exceed 1,875 parts per billion or about 2.5 times that from the 1850s.
Global Carbon Project
- The GCP is a Global Research Project of Future Earth and a research partner of the World Climate Research Programme.
- Established in 2001, its projects include global budgets for three dominant greenhouse gases CO2, methane, and nitrous oxide and complementary efforts in urban, regional, cumulative, and negative emissions.
- The main object of the group has been to fully understand the carbon cycle.
- It collaborates with many groups to gather, analyze, and publish data on greenhouse gas emissions in an open and transparent fashion, making datasets available on its website and through its publications.
- It releases the Global Carbon Atlas (established in 2013) a tool for visualising data related to the global carbon cycle.
