Extreme heat can snarl flights even without a cloud in the sky

“The weight at which you can operate (max gross takeoff weight) decreases as the temperature goes up,” explained Kathleen Bangs, a former airline pilot and current spokesperson for FlightAware, which tracks flight status in real time. “The hotter and more humid the surrounding air is, the more aircraft components and airfoil performance degrade.” (www.usatoday.com) Ещё...

Yes indeed the greedy power hungry big business of Global warming headed by that Huge bureaucracy called the IPCC can 100% be trusted as they have no agenda whatsoever. None of their power or paychecks are tied to climate change and of course they listen to all the science that states it is not caused my man.

And which country by far least pollutes and has the strictest environmental standards? China is building new coal-fired plants every week and understands the critical importance of cheap energy. They will never put themselves at the disadvantage Western liberals put their countries.

They will NEVER follow the protocols the West imposes on itself and the irony is they grow rich selling the West solar panels et al that PRECISLY guarantee our weakness and their strength....While they burn fossil fuels ad infinitum to manufacture, ship and sell us our own demise.

As usual, the usual suspects abuse the language for their ends.

Science demands rigorous debate over any posited theory or belief system whether or not it has been generally accepted or not.

The Earth was flat until scientists who were vilified at the time broke through the narrative hat was supported by those in power precisely BECAUSE the science threatened that power.

Do we see any parallels with today's situation?

In the 2012 cycle, the industry peaked with $15.3 million in total contributions. That figure decreased to $11 million in the 2014 nonpresidential election. Companies involved in coal mining gave Democrats a mere 4 percent of their donations in this election cycle, an unprecedented low

Justice inherited a coal-mining business from his father and still owns mines in five states. He also inherited his parents’ political preferences.

Quality of life for the human race, wildlife, sealife, food, all is disappearing fast. 50% of the population every year is without water part of the year. If this is a cycle in the weather. We still need science and society to control waste. South Africa cut their water usage to 13 gallons per person per day. US uses over 100 gallons
per person per day. Georgia peach farmers lost 90% of this year’s harvest to night time temperatures to warm. Who do you blame. Politicians, scientists, God, greedy rich fossil-fuel people. We need to work together. Longer we drag our feet. Harder it will be, more people suffer. 118 million people worldwide looking for new life. That number grow over a billion people if we can’t solve earlier than later. Good flights.

South Africa not only reduced its daily water usage per person, it is also exceeding its emission goals. Yay! But how? The country's grid is so poorly maintained due to incompetence, corruption and outright theft of copper wire for sale on the black market that they have what they euphemistically call "load shifting" or rolling blackouts. Even just a few years ago the power would go out for maybe 6-8 hours a day. Now 11+ hours a day is the norm throughout much of the country. The Western Cape may be the exception. If the pumps running the water system can't turn then water consumption will go down. My cousin's widow, who still lives there, says the conditions pose quite a challenge for food preparation and storage.

It's called Climate Change, yes it gets cooler in some areas, but a lot of that can be contributed to the melting of the ice caps which will bring cooler air further south to us. The displacement of water is the problem, it will rain excessively in one area causing massive floods, while there's a drought in another and crops don't grow. It's more of a balance upset than anything, whether that's caused by or accelerated by humans can be debated all day long, the scientific fact is that it IS happening.

For a discussion of the recent heat waves in the Northern hemisphere and their causes I would recommend Clifford Mass's blog, his July 20 entry. He discusses the situation in Phoenix, AZ, towards the end of his post. He is a Professor of Atmospheric Science at the College of the Environment, University of Washington (Seattle) and usually writes about NW weather. He does not doubt that the planet is slowly warming. But he is also very skeptical about the media's alarmist portrayal of weather events. And, by the way, the Southern hemisphere has been experiencing an unusually cold winter at the moment. A climate scientist in Argentina told me it is has been very cold (and the skiing is great!) this year. Johannesburg had its first snow in 11 years. https://cliffmass.blogspot.com/2023/07/is-global-warming-causing-massive.html?m=1

Yes, he was on weekly on KUOW. But NPR is fully onboard with the alarmist climate catastrophe narrative. The board running KUOW is even more so. If you check the bios of the 24 current board members they are either lawyers, accountants, techies drawn from the Seattle scene (Amazon, MSFT, etc), public relations, an"event planner" (whatever that is) and others. I believe one was an engineer. None are trained in one of the hard sciences and certainly none have training in weather or climate. When Prof. Mass refused to ascribe every very hot/cold day, rainy spell or drought to AGW, he was canned. His crime was giving a rational, science based meteorological explanation for changes in the weather. As he does for the recent spate of heat waves here and abroad in the blog post I referenced. Can't have a dissenting opinion in this day and age.

He was kicked off KUOW because of statements about admissions policies and math standards at UW. Horrors!

"University of Washington Professor of Atmospheric Science Cliff Mass spoke to KING 5 Friday after losing his second part-time weather gig at a public radio station.

This time, it was Tacoma based KNKX (Formerly KPLU) who picked up Mass’ normally non-controversial weather forecasts and discussions after 2011.

Mass moved to the station after he was taken off the air at the University of Washington owned KUOW over controversial statements involving mathematic standards.

His latest removal was not over what he said on air, but what he posted on his well-known personal blog, which notifies viewers that it covers weather, climate, and current events. In this case, the current events he covered involved his walk in downtown Seattle in the wake of protests where some in the crowd broke store windows, looted and set police cars on fire.
"What I saw had a big effect on me. Seeing how much was boarded up. Blocks and blocks" said Mass.

He said he sympathizes with the Black Lives Matter movement, but he does not think police should be defunded and that city and state leaders should be speaking out more about the damage in downtown and individual "thugs" who used the cover of protests to carry it out.

But it was his drawing of parallels between destruction in downtown Seattle and a critical point in Jewish and European history that is at the heart of his departure from KNKX.

That event is known as Kristallnacht. In November of 1938, Hitler Youth, and members of the SA, also known as "brown shirts," led two days of attacks on Jewish owned stores and synagogues, also resulting in arrests and murders.

Mass is Jewish and said his reaction to what he saw in Seattle triggered an emotional chord."
