Why are changes in acidity so linear with changes in ocean pCO2? Here's a simple explanation, equation (2) of this recent Nature paper.

Climate change might alter seasonal cycle of Arctic ocean acidification https://t.co/f5KyPSm4tZ

[James Orr @James1Orr]

What is the largest projected seasonal shift from climate change? Would you believe 6 months?

Does anyone know why the IPCC 2019 SROCC report is still "in press"?

see https://t.co/FfjFkBWXZ9

It's been 2 years already.

Seasonal and extreme diurnal variations similar for ocean CO2 system

[James Orr @James1Orr]

Extreme diurnal variations in pCO2, [H+], and Ωarag are comparable in amplitude to those of seasonal variations

@Jens_D_Mueller @JensTerhaar @aj_fassbender @AGDco2 For model results we tend to make comparisons in terms of in situ pH.

[James Orr @James1Orr]

pH changes are relative

@rmbundy "the listing of authors should include those, and only those, who actively contributed to the overall conceptualization, design, and execution of the research." - - Day & Gastel

@rmbundy Day devotes a whole chapter to this subject in "How to write and publish a scientific paper"

@matthew_vdh The new plot looks better but there remain very small differences relative to Fig. 2 in Egleston et al. Compare exactly where the curves intersect the left y axis.

[James Orr @James1Orr]

Great new functionality for the python community! Your plot differs slightly from the original in Egleston et al. (2010) because of their typo in the S term. See the fix in seacarb and mocsy's buffesm function. More detail in Orr et al. (2018, Appendix B) https://t.co/UQ2LDrkgJM

How one small town at the center of the outbreak has cut infections virtually to zero: test all 3,300 in town, isolate the 3 percent who tested positive. Infection rate 10 days later down to .3 percent. https://t.co/5Tgpa7cCgl

2/2 These exponential #COVID19 projections are upper limits (black & colored lines). The grey line is a lower limit, assuming doubling rates in Germany (2.7 days), France (2.5 days), and Spain (2.1 days) could be immediately slowed to that now seen in Italy (3.6 days).

[James Orr @James1Orr]

1/2 Projected #COVID19 cases over next 9 days in top 4 EU countries assuming same logarithmic growth as seen over past 2 weeks: Italy (19%), Germany (26%), France (27%), & Spain (33%). Data are from ECDC https://t.co/XQSASVWzbe Thin colored lines lag thick ones by 9 days.

This is a comedy sketch but it just sounds too real.

[Mark Handley @MarkJHandley]

This version includes South Korea. They were on the same growth curve til 7 days ago - ahead of Italy. The measures they adopted then (subject to the lead time in measurements) seem effective - still exponential growth, but similar doubling period to Japan now.

[Mark Handley @MarkJHandley]

Here's the coronavirus data, overlayed with the dates offset by the amounts shown. One of these countries is not like the rest. Everyone else will be Italy in 9-14 days time.
