Climate Change (For Those That Respect Science)

[mtrycrafts]

It's all good, AI will solve the crisis by eliminating the problem......, us. More power to 'em ;o)

Oh, a Terminator world.

Our planet has had multiple major weather shifts through its 4-billion-year history. I'm not sure if we are totally responsible but I agree with you that we are not doing anything to slow it down and are speeding it up according to our latest understanding of global warming. In other words, it might be happening anyway, but you would think we would at least try to slow it down.

Yes, indeed. But those shifts took very long time periods to happen and don't think the CO2 was ever as high as now. This one is happening way to fast from the 1500s industrial revolution and population explosion.

Living here in north St Augustine FLA. I feel we have dodged a bullet. Hurricane Idalia was forecast to hit Tampa Bay head on as a cat 3 then make its way to Jacksonville as a cat 1 or 2. Bad news for me. Then it moved north and west and diminished the damage. The water in the Gulf of Mexico is in the mid 80s and warm water temp acts as fuel for hurricanes. Whether climate change is human caused or not it is real and seems to be getting worse. Only 2 to 3 inches of rain but still 40 - 50 mph winds.

Going all the way back to the 23rd of Aug, Idalia was always targeted for the Big Bend area, with Crystal River , Cedar Key ( 21 miles apart via water) the targets. But like these things do, weather shifted the track or this would have come really close to north Ocala, St Augustine and Jacksonville. as it moved across the state. We moved our boats from Crystal River back to Ocala, but still the storm surge still did its job in Crystal River flooding hwy 19 which runs close to Kings Bay.

CO2 level was far higher- at some points, there was little O2 in the atmosphere but that was many millions of years ago.

There are other factors that influence the climate- the Little Ice Age ended in the first quarter of the 1800s- that coincided with the end of the Maunder Minimum (solar activity) and as with most climate activity, it's cyclical, with some aberrations.

China, Russia and India aren't doing their part and the rest of the World needs to stop poking the US with their sticks- they just don't have the balls to turn on those three countries.

We don't need 8+ billion people. If people who have nothing but dirt would stop breeding like small, furry animals, the world population would have a chance of dropping. The governments in many of these countries are dictatorships and to be honest, I wouldn't have a problem if other countries were to make this much harder to achieve- coups rarely lead to a better life for the population and one of the basic duties of government is to ensure the safety of its people- that's not happening in many places but it needs to change.

"Go forth and multiply' implies that someone didn't understand Geometric Progression.

The world population has more than doubled since 1975, even with wars, disease and the pandemic.

So this is climate change. Yesterday in Crystal River Fl. I say, its mother nature since they has been keeping decent records, 68 hurricanes have been recorded in the Crystal River, FL area since 1930. This is In Kings Bay.

A thought for improving shipping emissions: switch from large diesel engines directly driving the shaft back to the turboelectric drive. Conceivably you could use biofuels to fire the boilers, netting an essentially carbon free transport mechanism.

My friend in Estero said the last time anyone saw the Hooter's Restaurant in Ft Myers, it was floating into the bay.

Are you referring to ships?

 

[Steve81]

Yup. Those big diesels used on container ships, tanker ships, etc. are a pretty big source of emissions (and not just CO2).

A turboelectric setup could run on anything from nuclear (probably not for commercial shipping) to biofuel. You’d have the advantage of making a twin prop system easy to implement, with the ability to apply full backing power, even on just an individual prop for increased handiness of the ship. The US originally developed the technology because we were too cheap to pay the license costs for Charles Parsons’ turbines in WWI era warships (HMS Dreadnought being the most famous early example of a turbine driven ship). Before that, it was the triple expansion engine.

But those are the lowest cost systems for moving these ships- they can't very well change to a higher cost system and maintain their revenue, although the increase from using something more efficient might not be a large %.

Most large Navy ships and some of the mid-sized ones use gas-turbine propulsion. My cousin's son is was a Gas-Turbine Specialist in the Navy- I can get some info about efficiency/cost if you want.It would be interesting to see this.

In truth they could use a diesel electric powertrain For shipping as well and net the same benefit (trains use this). Turboelectric drive merely opens up a number of possibilities.

Gas turbines in military ships combine low weight and the ability to quickly ramp up/down power (vs the time it takes to raise steam) AFAIK. Would be interesting to hear how efficient they are.

We hear this more and more and more.
Couple this with FEMA just about being broke, and rebuilding will lose out to relocating.

This could go either way at the moment...If it heads towards land, oh boy.

Tropical Storm Lee forms, expected to become major hurricane. Is East Coast in danger?

Tropical Storm Lee formed in the Atlantic Ocean and is forecast to become a hurricane. Is the storm going to hit Florida? See spaghetti models.

Yeah, living in NE Florida I will be watching the path of this storm.

I Left Out the Full Truth to Get My Climate Change Paper Published

I just got published in Nature because I stuck to a narrative I knew the editors would like. That’s not the way science should work.

Best thing to do to climate deniers is refuse to sell them new, or service their existing air conditioning units.
Gonna be a lot of sweaty converts that day !!

Simple answer is that GT's are not very fuel efficient (varies from model to model). That's why you don't generally find them in merchant ships. They are used in warships for the reasons you stated. Fuel economy is lower down the priority list for them. That said, they generally have a CODOG (combined gas or diesel) setup. Diesel for cruising speed and best fuel economy and GT for when they need to put the hammer down.

I'll give it a shot when my supply of Atkins shakes runs out. Thanks for the tip! Nutrition looks adequate; a bit high in protein and would prefer a higher amount of fat, but it's got a decent amount of calories without a lot of net carbs. Is two scoops pretty filling?

. . .

I'm good with what I eat. It's fuel, and it tastes OK. That's all I need.

For what it's worth, I frequently consume shakes that consist of frozen fruit (strawberries or blueberries), whole grain oat flour, protein powder, extra virgin olive oil, cranberry juice concentrate, and a little sugar to balance the cranberry juice concentrate. I put everything in a 2-quart pitcher and hit it with a hand blender.

I buy custom protein powder mixes at truenutrition.com in bulk. They have a huge selection of protein powders. I've found them to be reasonably competitive in terms of cost, and the quality seems to be good (a lot of protein powders on the market do not have the amount of protein claimed). I order Bob's Red Mill whole grain oat flour in bulk online.

These shakes taste terrible without the cranberry juice concentrate to mask the other flavors. It is the only thing I've found that is strong enough to mask the other flavors. Even with the cranberry juice concentrate they're not great, but it's tolerable.

The amounts of the ingredients can be adjusted depending on your needs and the situation at hand. For example, if my next meal won't be for some time I can add more olive oil and oat flour. If I'm hungry and I just need something to tide me over before working out or running I don't add olive oil.

I learned the hard way that it's best to store the oat flour in airtight containers with clamp lids to keep the bugs out.

It's reasonably low cost and relatively convenient.

YMMV, of course. It's not for everyone.
