To limit global warming in 2100 to below 1.5°C above pre-industrial levels, many scientists assume that the large-scale use of negative emissions in the latter half of the 21st century will be needed. Negative emissions “suck” CO2 out of the atmosphere, allowing a more gradual reduction of emissions in the near-term
May 21, 2018 — Integrated assessment models (IAMs) that generate energy and emission pathways to limit warming to 1.5°C have generally relied on large amounts of bioenergy with carbon capture and storage (BECCS) to provide the required negative

May 5, 2017 — In the 2015 Paris climate agreement, 195 nations committed to limit global warming to two degrees above pre-industrial levels. But some, like Eelco Rohling, professor of ocean

April 25, 2017 — Global coal use must be cut by 70% within 25 years, oil use must fall 30% and gas can increase by only 2% out to 2040. The growing global population will instead get its energy from

February 27, 2017 — The Paris Agreement on climate change set new targets for the world. Notably, it called for warming to be limited to “well below” 2°C and for carbon neutrality (“net zero”) by the second half of this century.

January 12, 2017 — Victorian government plans to work with a Japanese company to produce hydrogen from brown coal in the Latrobe Valley are “a way of making brown coal look green”, according to one expert.
