Om de opwarming van de aarde af te remmen zullen we actief CO2 uit de atmosfeer moeten halen, naast de inspanningen die we al leveren om de uitstoot van broeikasgassen te verminderen. Een nieuwe studie onder leiding van de Universiteit van Cambridge toont dat de combinatie van goedkope, op natuur gebaseerde oplossingen en duurdere technologie de beste kansen biedt.

Luke Kemp, expert en risques globaux à l’Université de Cambridge, vient de publier Goliath’s Curse, un livre qui jette une lumière crue sur la fragilité du monde contemporain. Après avoir étudié plus de 400 sociétés anciennes sur une période de 5 000 ans, il identifie des mécanismes récurrents d’effondrement

As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Center in Svalbard, Norway, identified large stocks of methane gas leaking from groundwater springs unveiled by melting glaciers.

Global heating could become "catastrophic" for humanity if temperature rises are worse than many predict or cause cascades of events we have yet to consider, or indeed both. The world needs to start preparing for the possibility of a "climate endgame."

As the public conversation on climate change evolves, so too does the sophistication and range of arguments used to downplay or discount the need for action (McKie, Reference McKie2019; Norgaard, Reference Norgaard2011). A mainstay of this counter-movement has been outright denial of the reality or human causation of climate change (Farrell et al., Reference Farrell, McConnell and Brulle2019), supplemented by climate-impact scepticism (Harvey et al., Reference Harvey, Van Den Berg, Ellers, Kampen, Crowther, Roessingh and Mann2018) and ad hominem attacks on scientists and the scientific consensus (Oreskes & Conway, Reference Oreskes and Conway2011). A fourth strategy has received relatively little attention to date: policy-focused discourses that exploit contemporary discussions on what action should be taken, how fast, who bears responsibility and where costs and benefits should be allocated (Bohr, Reference Bohr2016; Jacques & Knox, Reference Jacques and Knox2016; McKie, Reference McKie2019). We call these ‘
