Worrying Rise in Global CO2 Forecast for 2019

The level of climate-warming carbon dioxide (CO2) in the atmosphere is forecast to rise by a near-record amount in 2019, according to the Met Office. From a report: The increase is being fuelled by the continued burning of fossil fuels and the destruction of forests, and will be particularly high in 2019 due to an expected return towards El Nino-like conditions. This natural climate variation causes warm and dry conditions in the tropics, meaning the plant growth that removes CO2 from the air is restricted. Levels of the greenhouse gas have not been as high as today for 3-5m years, when the global temperature was 2-3C warmer and the sea level was 10-20 metres (32 to 64 feet) higher. Climate action must be increased fivefold to limit warming to the 1.5C rise above pre-industrial levels that scientists advise, according to the UN. But the past four years have been the hottest on record and global emissions are rising again after a brief pause.
