Methane rises to highest level on record
Animal farming and fossil fuels have driven global emissions of methane to the highest level on record, according to new data from the Global Carbon Project. Since 2000, emissions have risen by nine per cent (approximately 50 million tonnes a year), and concentrations are currently increasing at a rate of around 8–12 parts per billion (ppb) per year.
