I See No Ships (hurricanes)

Why is everyone trying to minimise the suffering of many thousands of people by claiming there has been a long period of no hurricanes in the Atlantic (adding to hit mainland US). There has been no real lull in the number of hurricanes:
e.g from Roy Spencer:

The 11-Year Major Hurricane Drought: Much More Unusual than Two Cat 4 Strikes

September 21st, 2017 by Roy W. Spencer, Ph. D.

Weather.com published an article noting that the two Cat 4 hurricane strikes this year (Harvey and Irma) is a new record. Here’s a nice graphic they used showing both storms at landfall...

What Roy Spencer Thinks of Europe

Trump you did the right thing ! Excellent president the best we have ever had.
————
Really?
few other leaders have been made the ultimate laughing stock of the rest of the world.
Even Bush and Regan were more respected
  • I don’t care if we are a laughingstock to a bunch of countries whose claim to fame is artists and musicians who died hundreds of years ago. Some of us laugh at you, too. Your countries are slowly dying, culturally and economically.
    Good luck.
phew!

Nenana Ice Classic is over for 2017

The Nenana Ice classic is a non-profit corporation formed by the residents of Nenana, Alaska, for the purpose of conducting an annual ice pool contest under special statutory authority enacted the first state legislature in 1960. The Association was incorporated by the State of Alaska in December 1972. Previously it had operated as an unincorporated association.

The idea is to guess the exact time of the ice break-up on the nenana river
This contest has been running since 1917 and consequently gives an idea of thermal conditions on the river over time. Unless dynamite is used(!) the time of breakup is difficult to contest and calling "Fraud" even more contentious.

Three plots are given 2 timed from the start of the year and one from the vernal equinox (the latter uses a fixed point in solar time).

Looks like the break up occurred at a time predicted by the slope of the average

Arctic Sea Ice to December 2016




First plot shows rate of change per day - Note wild fluctuations from October
Second plot show Extent on day of year - A few have line fits which show that the extent reduction is a reasonable fit to a straight line
The final plot shows the usual plus a rate of change per year.
