JAMES HANSEN: A New Frontier?

Hurricane Calvin was once up to 125 MPH.  Now down to a tropical storm and positioned 230 miles due south from where I am composing this posting.
The rain and floods were not much.  I almost could have gone golfing.  From where I sit composing this blog, here is a photo towards the eye of Calvin.
Three sports events of note this weekend:
  • The Women's World Cup will begin with New Zealand vs Norway at 3 AM EDT tomorrow morning (9 PM Hawaii tonight) and U.S. vs Vietnam at 9PM EDT (3PM Hawaii) Friday.  Not sure if she will start, but Trinity Rodman is a rookie on the American team.  Yes, daughter of Dennis Rodman, here with her mother.
  • The Tour de France bike race ends on Sunday, with a recap on NBC at 5PM EDT (11AM Hawaii).  The entire race can be seen on Peacock and USA.
  • The Open tees off at Royal Liverpool from 4AM EDT Thursday (10PM Hawaii tonight) on the USA channel.  Your NBC channel will then show the entirety (8 hours the first weekend night, meaning from Friday night, and 7 hours on Saturday night through Sunday morning) from 7PM EDT (1AM Hawaii).  Rory McIlroy won last weekend at the Scottish Open, so is favored to hoist the Claret Jug on Sunday.
I'm on James Hansen's mailing list, and this was his latest:

Andy Revkin recently asked whether the “climate dice” have become more “loaded” in the last 15 years. Climate dice were defined[1] in 1988, after we realized that the next cool summer may cause the public to discount human-caused climate change. The answer is “yes,” the dice are more loaded as we will explain via the shifting bell curve (Fig. 1). The shift is large enough that most people notice the change, but that doesn’t prevent a person with a bias from taking the cool June in the U.S. this year (Fig. 2) as proof that global warming predictions were wrong – and, of course, a loose cannon on Twitter has done just that. That’s nonsense, of course. On global average, June 2023 was easily the warmest June in the historical record, as we will illustrate below.

What to do about loose cannons?
  • Censor them?  Nope, for this leads to enforced conformity, which has serious consequences.
  • You can't censor a loose cannon.  Focus on educating those people who are open-minded.
In testimony to Congress in 1988 and 1989, and in a paper attached to the 1989 testimony, we noted that global warming causes wet places to get wetter and dry places to get drier.  Thus hand in hand with all this heat this summer, you keep reading about floods, everywhere.  To the right above, photo of Makiko Sato.
Kerry Emanuel of MIT used sea surface temperature increases from our 2×CO
2 
experiment to estimate the effect on maximum intensity of tropical cyclones. Minimum sustained surface pressure fell from 880 mb to 800 mb and maximum potential wind speed increased from 175 to 220 miles per hour.  No serious hurricanes this year, but it's still July.
Are we entering a new climate frontier?
  • Suspicion is that we are, something not seen in the past million years.
  • Figure 3 argues so because in the Earth Energy Balance, global warming will worsen if we continue to add more energy on balance into the atmosphere.
  • This current El Nino will only accelerate the warming.

[2] For example, belief that we can still solve the climate problem via just greater reduction of greenhouse gas emissions. Or belief that borrowing enough money from our grandchildren to build solar panels and windmills as fast as possible will significantly reduce global CO2 emissions. Or that support for nuclear power is “not needed” because solar power is so cheap (Nuclear power is a needed carbon-free complement to renewables and viable scenarios for decarbonized electricity include an increasing role for modern nuclear power, but there is a total disconnect with financing (Bowen, M. and K. Guanio, 2023: A critical disconnect: Relying on nuclear energy in decarbonization models while excluding it from climate finance taxonomies, Commentary, Center on Global Energy Policy at Columbia University.).

Nothing to do with the above.....but, how to vacuum your dog.

THE ENIGMATIC PHIL SPECTOR

The first presidential debate of Donald Trump and Joe Biden ended up in a near tie.  Both lost.  However, it was an unmitigated disaster for Biden, who just might be too old to win this re-election. For Trump, it was a reinforcement of what he does all the the time, lie.   There will be significant calls for the Democratic Party to work out "something" to replace Biden as their presidential candidate.  Suddenly, Kamala Harris, Gavin Newsom and Michelle Obama are added to the spotlight.  But what can "legally" occur at the August Democratic Convention? The situation is different on the Republican side, as Trump is the Republican Party, and no matter if he gets 4 years at his felony sentencing on July 9, or even if the Supreme Court determines he is not immune next week or later, he will be the presidential candidate. Trump is a damned boastful liar and convicted felon, but that is the only option for Republicans.  His vice-presidential choice now become...

ON THE MATTER OF PUBLIC HOLIDAYS

Hawaii today celebrates King Kamehameha the First Day as a public holiday.  Next Monday, June 19, or  Juneteenth,  is a Federal holiday.  However, 22 states, including Hawaii, do not recognize this as a public holiday.  Four of these will begin to honor this day next year, not Hawaii.  Juneteenth commemorates the end of slavery.  Here are the Hawaii holidays, and note three that only we have: New Year’s Day: 1st day in January Dr. Martin Luther King, Jr. Day: 3rd Monday in January Presidents’ Day: 3rd Monday in February Prince Jonah Kuhio Kalanianaole Day: 26th day in March Good Friday: Friday before Easter Easter:   Calculating Easter Memorial Day: Last Monday in May King Kamehameha I Day: 11th day in June Independence Day: 4th day in July Statehood Day: 3rd Friday in August Labor Day: 1st Monday in September Veterans’ Day: 11th day in November Thanksgiving Day: 4th Thursday in November Christmas: 25th day in December There are  11 paid Fede...

THE TRUMP ENERGY PROGRAM

From  Time  magazine, I begin with a slew of Trump topics.  You can read the details. The unpopular Big Beautiful Bill is now in the House . The only truly effective anti-Trump person:  Elon Musk. The Trump Gaza ceasefire proposal . The July 4th Free American Anti-Trump Protest planned across the USA . This site began as a renewable energy and environment blog, and has evolved to just about any subject.  I try to keep Wednesdays for sci-tech, with perhaps a monthly focus on energy.  More recently, I've drawn from the  Energy Matters  info sent to me by the American Energy Society.  I'm inserting direct quotes this time to eliminate my predilections for more credibility. This service starts with some broad topics. - Fossil fuels: Helium is locked in a supply crunch, and prices are surging. - Renewables: Congress will probably pass new renewable fuel standards for 2026 and 2027. - Policy: President Trump is now focused on Califor...
