You mean the climate will cool naturally due to the Sun dimming before we do anything to make the Earth not heat up? Since you have strong opinions on climate change, can you answer a question I posed a couple of pages back?

What is the right temperature of the Earth?

We can go to colder places, but it's hard to go to a place that's 800F.

Because there's no atmosphere, Mercury is cooler than Venus. We could go to Mercury. Strange, really.

To get to that conclusion, they have to set pre existing conditions that would allow liquid water on the surface. In other words, they have to set pre conditions that would create the desired outcome. But even then, it's a very weak assertion.

Sun output = 30% less --> Solar irradiance on Venus = 40% higher than current Earth. Do you really believe you'd have oceans here with 40% higher solar?

Actually, if they had oxygen in either Venus or Mars atmosphere, that would be a signal of life. But both have high co2, which indicates the opposite. All that's left to search for under category "life" is microbes that are anaerobic and/or live in high sulfur conditions.

Now let's go back to the headline. "Venus may once have been habitable."

Really? That "early 2 billion years" is a continual rain of asteroids, hellish conditions of continual volcanos... it's the planet becoming a planet, aggregating. So if it has a lot of water, that water becomes water vapor. Huge amounts of it, just like now Venus has huge amounts of co2.

In the absence of a magnetosphere, the solar winds would strip the H20 and other volatiles apart, and ultimately you'd be left with the tail end of the energy equation, CO2. And that's what you have on Venus.

With enough mass in the atmosphere (initially h20 if you like), the surface pressure would easily force water vapor into liquid form. That's a steam boiler, not an ocean. Evil Kneivel's rocket was just that, superheated steam.

Earth is by definition in the 'habitable zone'. Venus and Mars are not. Note that the known fact that Mars had ancient oceans is contrary to the hypothesis of an ancient dimmer sun. If anything, it would indicate an ancient stronger sun.

Given that there are many basic facts about the virus that were wildly unknown in Feb...

I guess my comment would be your handlers ARE going to try to sling mud based on the administration's handling of Covid, we might as well wait and see if anything sticks.

By the way, I'm actually not aware of Trump advising people on Covid's deadliness. Seems like he's mostly advised people to listen to their local or state health officials, right?

I found that Nevada rally interesting, because their governor had banned meetings > 50 people (which cut out a convention in Vegas I was registered for). Should Trump have followed that? Was he obliged to? Were the people free to go to the rally if they wanted?

Decaf violates nature.

The surface temperature is in the range to melt lead, not to boil it.

Anyway it was much more like earth before.
No. Never. I suspect you are referring to a totally unscientific piece of dogma repeated by the climate alarmist crowd, that Venus is the result of global warming, greenhouse, blah-blah-blah.

It has massive sulfuric acid clouds that trap and reflect solar energy in the cloud layers. The surface is 97 times that pressure of Earth.

Venus RECEIVES far more solar energy than Earth. It's closer to the Sun. The sulfuric acid and the temperatures would make short work of any microbes trying to survive, wouldn't they?

I'm not sure about any of that.

The Renaissance, industrialization, the birth of science, the Reformation...all came after a firm establishment of caffeine in western culture.

I don't read the facts that way.

Who says it was once nicer?

I suspect there are far more Mexicans jumping the border for Covid treatment in Texas than CA, but it's just a guess.

This brain atrophy can all be explained from a lack of coffee. Don't worry, when the coffee shops all open back up people will start to look normal again.

Have you considered it may be your brain that has slowed down, and sees them in slow motion, rather than they who have actually slowed down?

People have studied this. Here is one example.

I'm not seeing it as that deadly, but it does seem very contagious. The "count" isn't a decent measure, and I'm sure you are familiar with the comorbidities.

The atmospheric dynamics of Venus are totally different than Earth, and the concept of the greenhouse effect does not apply.

The atmosphere is very deep, such that on the surface the pressure is almost enough to liquify carbon dioxide. The temperature there is > 800F.

Any microbes that could possibly exist would be high in the atmosphere, where a suitable temperature and pressure existed for that form of life.

Since the time constant of water dammed up in a lake or reservoir is much longer than if it were in a stream, water in such a body would have more surface area, and more evaporation, than if it were in a stream or river.

That would result in more rain, and more cooling.

There are other problems with your arguments in the post, this is only one.

When a chemical reaction or process resulting in an end product is not known, it would be unwise to suggest that life is the cause, simply because that is a cause we know of on Earth.



...It is also found in Jupiter's turbulent atmosphere, where it forms in the planet's hot interior and reacts with other compounds in the upper atmosphere.[16] The abiotic synthesis of phosphine takes enormous amounts of energy, such as in the planet-sized convective storms of gas giants.[17]
Phosphine has also been detected in the atmosphere of Venus, where its origin is currently unexplained. The paper announcing the discovery suggests that the phosphine "could originate from unknown photochemistry or geochemistry, or, by analogy with biological production of PH3 on Earth, from the presence of life".[18][19][20] Venus lacks the high temperatures and pressures to form phosphine the way gas giants such as Jupiter do, requiring an alternative explanation for its presence.[20]

Can you make a coherent statement about your confusion or is your confusion confused?

We will run them in reverse.

So we should bet on the house in Vegas casinos?

That's not allowed because the house always wins.

High altitude drones may also drop hundreds of thousands of syringes, each with little controllable fins, individually targeted.

I only watch TV shows where the characters are glued to their mobile phones.
