More time …. really?

A recent paper about [e]mission budgets and pathways consistent with limiting warming to 1.5 °C essentially argues that it is still possible to follow an emission pathway that will give us a good chance of keeping warming below 1.5oC. More specifically, … Continue reading

Prior knowledge

Something I have been bothered about for some time now, is how we best discuss climate change in the context of extreme events. Given the devastation from Hurricanes Harvey and Irma, damaging floods in South Asia and Nigeria, and the … Continue reading

Machine unlearning

Someone sent me a paper by John Abbot and Jennifer Marohasy called the application of machine learning for evaluating anthropogenic versus natural climate change. Their conclusion is that most of the observed warming could be natural and that the Equilibrium … Continue reading

Kate Marvel on clouds

Although we are confident that adding greenhouse gases to the atmosphere will cause the planet to warm, exactly how much we will warm is uncertain (the IPCC likely range for a doubling of atmospheric CO2 is 1.5oC to 4.5oC). A … Continue reading

STS: All talk and no walk?

In my previous post I discussed a paper by Harry Collins, and colleagues, that is mainly a response to an editorial by Sergio Sismondo. Collins et al. argue that Science and Technology Studies (STS) must take some responsibility for today’s … Continue reading
