"Co-author BAS Biological Oceanographer Dr Sophie Fielding says: "This finding is essential for understanding the ocean's capacity for carbon capture. As atmospheric carbon dioxide levels increase, it's essential for us to understand both the physical and biological mechanisms for fertilising the ocean with iron.""

"The onset of heavy greenhouse gas (GHG) emissions from conventional construction practices has led to research on several plausible low-carbon dioxide footprint construction materials that are either carbon dioxide neutral or carbon dioxide negative. One such ‘green’ construction material is lime hemp concrete (LHC), hemp concrete or hempcrete, which are some of the many names of this novel construction material."

"Because time travel is not an option, we will need to develop what are known as "carbon removal" solutions that can clean up large volumes of CO2 from the atmosphere. A wide variety of carbon removal solutions have been proposed, ranging from basic tree planting and ecosystem restoration to high-tech devices that hoover up CO2 directly from the atmosphere, as shown in the figure below. While carbon removal solutions face many commercialization hurdles, estimates show a very large technical scale potential for a portfolio of solutions if these challenges are tackled successfully."

"Until now, there has been no serious questioning of the intention to limit the temperature increase to 2 or even 1.5 °C. Not that many in the climate research community seem to grasp the political rationalities behind the setting of long-term policy targets. Even the mainstream policy discourse assumes consistency between talk, decisions, and actions."
