Carbon markets rule change would harm mitigation and Indigenous peoples
Reply to Oreska et al ‘Comment on Geoengineering with seagrasses
In their comment on the review paper, ‘Geoengineering with seagrasses: is credit due where credit is given?,’ Oreska et al 2018 state that some of the concerns raised in the review ‘warrant serious consideration by the seagrass research community,’ but they argue that these concerns are either not relevant to the Voluntary Carbon Standard protocol, VM0033, or are already addressed by specific provisions in the protocol. The VM0033 protocol is a s…
Reply to Macreadie et al Comment on ‘Geoengineering with seagrasses
Macreadie et al (this issue; M 2017 Environ. Res. Lett. ) challenged the conclusion presented by Johannessen and Macdonald ( 2016 Environ. Res. Lett. ) that global estimates of carbon sequestration by seagrass meadows were too high. Here we clarify our global calculation, respond to M2017’s criticisms and explain how the persistent misunderstandings about sediment dynamics within the Blue Carbon community continue to lead to overestimates of carb…
Geoengineering with seagrasses
Blue carbon, the carbon fixed by vegetated coastal ecosystems including seagrasses, is reported to have a large potential to sequester atmospheric carbon dioxide. Planting, expanding or protecting seagrass meadows has, accordingly, been proposed as a form of geoengineering. Seagrasses are reported to account for up to 18% of the carbon burial in the world’s oceans, which is on the same order of magnitude as other proposed geoengineering technique…
It is not just about the ice
Much concern has accompanied the dramatic decrease in area covered by permanent pack ice in the Arctic Ocean during the past two decades. Ice is undeniably the most obvious feature distinguishing the Arctic Ocean, and its loss seizes public and scientific attention like no other tipping point. Beneath that challenging ice surface lies an ocean that is strongly affected by other less-visible factors that also have a large say in how change will oc…
