evidence: Fossil fuel-related CO2 emissions reached 32 Gigatonnes in 2010. These emissions come from industrial processes and stationary emission sources, such as power stations, cement production and refineries. About 50 per cent of the total anthropogenic (human-made) CO2 emissions between 1750 and 2010 have been produced in the last 40 years. [...] The Intergovernmental Panel on Climate Change (IPCC) says that for well-selected, well-designed and well-managed geological storage sites, CO2 could be trapped for millions of years, retaining over 99 per cent of the injected CO2 over 1000 years. [...] Gases in the Earth’s atmosphere act as an insulating blanket around the planet, trapping more of the Sun’s heat.
