Phase Plane plots of COVID-19 deaths with uncertainties

I. Introduction. It’s time to fulfill the promise made in “Phase plane plots of COVID-19 deaths“, a blog post from 2nd May 2020, and produce the same with uncertainty clouds about the functional trajectories(*). To begin, here are some assumptions … Continue reading

Acceleration in rise of Global Mean Sea Level (Yi, Heki, Qian, from 2017)

Most impressive! This is Figure 2 of S. Yi, K. Heki, A. Qian, “Acceleration in the global mean sea level rise: 2005-2015”, 2017, Geophysical Research Letters: See also their data supplement. Of particular interest to me is their use of … Continue reading

Repeating Bullshit

Originally posted on Open Mind:
Question: How does a dumb claim go from just a dumb claim, to accepted canon by the climate change denialati? Answer: Repetition. Yes, keep repeating it. If it’s contradicted by evidence, ignore that or insult…

No, Senator Marco Rubio and Larry Kudlow, we know how much humans contribute to climate change, at least precisely enough for Congress and an administration

14th October 2018, quoting Senator Marco Rubio and White House economic advisor Larry Kudlow, the Washington Post reported they each claimed that the recent UN report was an `overestimate`: “I think they overestimate,” Kudlow said of the U.N. report, which … Continue reading

Sea-level report cards, contingency upon model character, and ensemble methods

Done by the Virginia Institute of Marine Science, new sea-level report cards offer a look at current sea-level rise rates, and projections. What’s interesting to me is making the projections conditional upon the character of the model used to project. … Continue reading

Less evidence for a global warming hiatus, and urging more use of Bayesian model averaging in climate science

(This post has been significantly updated midday 15th February 2018.) I’ve written about the supposed global warming hiatus of 2001-2014 before: “‘Overestimated global warming over the past 20 years’ (Fyfe, Gillett, Zwiers, 2013)”, 28 August 2013 “Warming Slowdown?”, Azimuth, Part … Continue reading
