„The basic idea is to protect coastal wetland ecosystems – mangroves, seagrass beds and salt marshes – because the plant biomass and soils sequester and store carbon at rates up to 50 times higher than their terrestrial counterparts. While sequestration and storage can vary greatly across geographies and ecological conditions, it is estimated that global blue carbon systems store at least 45 Mt CO₂ per year. It is further estimated that if coastal wetlands were restored to their extent in 1990, annual carbon sequestration would increase to 160Mt CO2 yr-1. Blue carbon ecosystems also provide a suite of co-benefits, including mitigating sea level rise, providing critical fisheries habitat, and nutrient filtration.“

„There is no doubt that a rapid rise in the earth’s temperature will impose high costs on not only our environment and health but also our economic and physical security. In recognition, most nations have committed to significant mitigation efforts. But will these collective efforts be enough? Some scientists are trying another approach, exploring new tools that can deliberately alter the global climate system. The problem is, while several tools seem to be gaining traction, knowledge of them is not widespread and there has been too little transparency and international dialogue around their progress, feasibility, risks, and benefits.¹ Documenting and tracking the array of tools in development will be crucial for understanding their full impact, debating their implementation, and safeguarding their appropriate use.“

„The international community has already missed its chance to limit global warming to between 1.5 and 2 degrees Celsius, according to a new study by Switzerland-based researchers. But a solution to the problem could lie in geo-engineering technologies.“

„The next stage of humanity’s fight to reduce greenhouse emissions may revolve around seaweed, according to tonight’s episode of ABC’s Catalyst, presented by Professor Tim Flannery, which asks the question “can seaweed save the world?”“
