The actual facts say otherwise. When looked at over decades we are getting stronger hurricanes more often. Even with signicantly better construction codes we, in the US, are still seeing more damage. The only good news is that we are much better at predicting storm paths that allow people to get out of the way or to prepare themselves better.

True, man centuries of work by seriously smart people can not be discounted. Any yet for some perverse reason many seem to be incapable of dealing with the fact that the climate is changing and that human caused emission of greenhouse gases are the cause.

No matter how you look at it aviation is very energy intensive. A 737 consumes about 750 gallons of fuel per hour and a 747 consumes about 3,000 gallons per hour (clearly these are rough numbers since shorter flights consume more fuel per flight hour, fully laden vs empty etc etc.). On a per passenger basis that is approximately 7 gallons per hour. While on a mile travelled basis a commercial jet is way more efficient than say a regular car this is offset by the fact that one travels so much further in a jet. In a car for a 10 hour drive I am very lucky to travel 600 miles, in a 10 hour flight I can get to travel close to 6,000 miles. It is unlikely that there is a solution to the carbon emissions of long haul flights, short haul flights may be different. We need to make progress where we can, aircraft that don't emit CO2, more efficient jets, more efficient routes and eventually probably such technologies such as direct air capture of CO2. Clearly we have a problem a

The "only theories" argument show a total absolute zero understanding of science. Put simply science collects a whole bunch of facts and them works out a theory that best explain those facts. As more facts become known they either confirm the theory , show where it is invalid and improves it. Also a new theory has to be consistent with existent theories or show why existing theories are wrong. We now have over thousands of man decades of research in to the climate and how it works. For climate scientists to be wrong now would require overturning just about every theory in science. It is just not rational to think that is in any way probable. As for other causes such as changes in orbits etc.....they have been evaluated, by numerous groups over many decades, and have found not to fit the facts. As someone said:" science is the process that stop use believing something that we wish was true but isn't and makes us believe something that is true that we wish it wasn't . Climat

Airbus A320 first flight March 1984 Boeing 737 First flight April 1967 I don't know about you but 17 years seems pretty significant age difference to me. It will be 2040 before the age of the A320 is as old as the 737....

Your numbers on CO2 emissions for EVs is wrong. I am unsure where your "well known" people are getting their facts from. For example see: https://www.iea.org/data-and-statistics/charts/comparative-life-cycle-greenhouse-gas-emissions-of-a-mid-size-bev-and-ice-vehicle Also if you look in detail at most of the analysis done they considerably overstate the CO2 emissions of EVs. Most of the analysis assumes that the battery going into an EV is one use and done. However most of the materials in an EV battery are valuable and are getting recycled (not a lot yet). If we take the Prius battery as an example ( many more around for much longer) there are almost none of those batteries going into landfills as they are too valuable. A dead Prius EV battery is worth at least $200-$300 each. Additionally many analysis assume a smaller than probable vehicle lifetime mileage. In the example I give about they assume that the EV only lasts for 124,000 miles (200,000Km) which is ridiculousl

Just the other week the Speaker of House husband was attacked in their home. My Congressman, a Dem, was at the receiving end of death threats from the QAnon crowd.

Sadly I think we are well past the point in doubting the link between people expressing the wish to do harm to others on-line in the press etc. and then they, and or others, carrying out actual acts of violence. History is just loaded with endless examples - some old, but many new. The First Amendment, like all the Bill of Rights, has limitations and is not an unlimited right to stir up hate. Where to draw the line is tricky, but that does not mean the line cannot be drawn. The funny thing is there is a whole sub-industry devoted to tracking key executives due to merger and acquisition activities so banning one Twitter account does very little. But we are here to talk about planes.
