“Wettest 12 Months in U.S. History” (Weather Underground)  No surprise there.  The charts and tables in the story are worth a good look, showing the reality of an unwanted effect of climate change.  The long-term trend indicates that many more new records are likely to be coming but fortunately still stretched out with drier intervals in between.

How today’s flooding is affecting the Mississippi River (E&E News).  “Experts say the new floods come faster and more furiously than their 20th-century counterparts. They last longer and are less predictable. And they cause more property damage…..Climate change…acts like an accelerant on flood conditions.”

Mauna Loa has recorded its first day with CO2 above 415 (EcoWatch).  This has gotten some headlines, but don’t forget that May is the seasonally peak month and we will soon be seeing a sharp decline until September.  Also, Mauna Loa is subject to shifts in incoming winds from widely separated sources and thus gets an abundance of numbers that deviate sharply from the main trendline.  By the end of the month that line will have completed a pivot and the peak should be clearly defined, enough so for comparing with previous peaks.  In any case, the advance is much too great, well above 2 ppm for the last 12 months, signifying no progress at all in curbing emissions.
–This page has two charts that pretty well summarize the whole story.  I only wish the lower one could be extended back another year or two for a view of more short-term trendline details.

The amount of investment funding needed to meet climate goals is far from being met (Phys.org).  The IEA has produced new data that is clearly disappointing.  “Money going into new upstream oil and gas projects—exploration, drilling and infrastructure—rose four percent in 2018, while investment in new coal sources went up by two percent, the first increase in that sector since 2012…..At the same time, investment in new renewable power of all kinds dipped by about two percent.”  Governments are being blamed because of their lack of commitment to climate action that would otherwise show better support for commercial or industrial investors.
