    1. Net zero by 2025 is not physically impossible. There is no real barrier to deploying the technology required or to achieving the necessary changes in behaviour. But to achieve this, it is not a question of physical possibility but rather whether you believe it is possible to change the economic structure and political decision making of the UK (and EU and world) overnight to allow us to deploy all possible solutions over the next five years.
    1. Netto-Null-Ziel müsste also hier schon Ende 2028 oder sogar Ende 2025 erreicht werden. Das entspricht der Forderung der noch recht jungen Umweltbewegung Extinction Rebellion, die im Frühjahr durch spektakuläre Straßenblockaden in London weltweit bekannt geworden ist. „Wenn man 1,5 Grad mit einer Zwei-Drittel-Wahrscheinlichkeit erreichen will und die Feedbackmechanismen des Erdsystems und die größere Verantwortung von Industrieländern berücksichtigt, dann ist das die logische Konsequenz“, sagt Klimaforscher Rogelj.
    1. Our work clearly demonstrates that we already have the tools and technology needed to efficiently power the UK with 100% renewable energy, to feed ourselves sustainably and so to play our part in leaving a safe and habitable climate for our children and future generations.

    1. In general, while I've been reading Stuart Kauffmann's At Home in the Universe, I can't help but thinking about the cascading extinctions he describes and wonder if political extinctions of ideas like Communism or other forms of government or even economies might follow the same types of outcomes described there?

    1. Physiological plasticity has the potential to buffer organisms from warming by reducing the thermal sensitivity of life-sustaining processes and increasing physiological tolerances (3, 4).

      This is interesting!

    1. that we owe what ecologists like David Tilman call an ‘extinction debt’ (Tilman et al., 1994, pp. 65–6)—and that this debt will be paid.

      For more on the concept of 'extinction debt'; read this article: http://www.nature.com/nature/journal/v371/n6492/abs/371065a0.html

      Essentially my understanding of 'extinction debt' refers to species becoming extinct in the future because of things that have happened in the past. Tilman refers to the destruction of a species' habitat as the main cause of that species becoming extinct. Makes absolute when I think about it.

    1. In a remote, mist-wrapped island north of the eastern tip of Siberia, a small group of woolly mammoths became the last survivors of their once thriving species.

      Love to read about mammoths!
