Dpiso,
Lets go out on a limb and suggest that I meant Iran. Iran is #6 on the list. Russia and Iran combined about equal India and will never reduce their
CO2 emissions or stop selling oil until they run out. China isn’t going to stop either.
Whats better about living in a concrete box? Most of which leak when it rains!

My "concrete box" doesn't leak when it rains. Neither does almost anyone else's I know.

S,
Great, there are a number of $1M US + block houses around us that fix the roof every year after it rains. I’m glad your’s doesn’t leak.
To the other climate extremists, it’s a lot easer to talk the talk than walk the walk.
We walk the walk!

It requires maintenance, like everything in this climate. I go up every year or two, powerwash the roofs and apply another coat of waterproof paint.
And use the fiberglass sealer fabric over any cracks that develop. The people with million dollar plus houses aren't hands-on, so they aren't aware of
things to check until it becomes a problem.

S,
The 1st roof we did in San Felipe in 2006 has never leaked. We used the snow roofing system. Only needs a coat of elastomeric white coating every few
years

A million-square-mile gravity hole that is lowering the oceans
300 feet lower sea level? Thats a huge difference!

What, me worry?
‘We are in uncharted territory’: World records hottest day ever for the third time in just four days
The planet registered its hottest day since records began for the third time in just four days this week, deepening fears about the far-reaching
changes taking place in Earth’s system because of the climate emergency.
Unofficial data from U.S. researchers showed the planet’s daily average temperature soared to 17.23 degrees Celsius (63.01 degrees Fahrenheit) on
Thursday, surpassing two previous heat records registered in recent days.
The extraordinary feat comes shortly after the European Union’s climate change service confirmed the planet observed its hottest June on record,
with unprecedented sea surface temperatures and record low Antarctic sea ice.
Climate scientists are deeply concerned.
Indeed, the U.N. weather agency recently warned that the combination of ever-increasing greenhouse gas emissions and the return of El Niño is likely
to mean the worst is still to come.
“The global temperature record smashed again yesterday,” Bill McGuire, professor emeritus of geophysical and climate hazards at University College
London, said via Twitter.
Woke!

No leaks at my house. A steel house 300 yards from saltwater? What could possibly go wrong?

PB,
Got rebar? Got drywall? Both rot in this level of humidity, you just can’t see it.
Our place is cement on the outside and inside. The steel is in the middle just like rebar, but unlike rebar it’s all coated so it won’t rust.
Containers are 10 year rated for salt spray on a ship without any extra coating. We have coating, cement and sealer on the cement.
What’s in your walls? Think condos in Florida here!

I worked for almost a year on a missile defense project in the Aleutian Islands. All of the rebar used in that project was epoxy coated to prevent it
from rusting out over time.
Due to either a change in design, or an error in the original plan we had to demolish some of the early construction about six months into the
project. The way the concrete separated from the rebar, you would think it was coated with teflon.
If you are not living on the edge, you are taking up too much space!
"Could do better if he tried!" Report card comments from most of my grade school teachers. Sadly, still true!

AK,
A lot of Mexican construction leaves the rebar sticking out at the top and ends which can allow water to seep in. There’s also a blow through
problem with block walls in very high winds. Even ones coated with cement or plaster. (Cracks!)
Most of the US buyers here never watched their houses being built. If they had and knew anything about construction they’d never buy some of them.
But you also need to consider the source.

It isn't really water "seeping in". It's that the rebar sticking out starts to rust and the rust travels along the length of the rebar. And rust never
sleeps.

is it true they leave rebar sticking up so that the building isn't finished and there's some tax savings?? or is that wives tale?

S,
Water is why the steel rusts. Steel takes Oxygen from the water and for most steels the oxide coating is soluble in water. Aluminum is far more
reactive in water than is steel but aluminum’s oxide coating isn’t as soluble as steel’s so it protects the aluminum from further oxidation
The reason stainless steel won’t rust is because it’s passivated so that most of its surface is really nickel. Passivation removes the surface
steel and leaves the nickel.
SB,
No, that’s the reason “Taxes”!

Of course water, in the form of rain, or high humidity is what causes steel to rust. Duh. I don't know why you think it necessary to mansplain the
obvious to me.
What I was saying is that you could seal really well around rebar sticking out of the roof, so no water could seep in, but the exposed rebar will rust
and the rust will eventually travel through the length of the rebar in the walls.

You’re the one who said, “it isn’t really the water seeping in”! But it really is!

Y’all are professional engineers, eh? Experts in structural, corrosion and civil!

One doesn't need to be a "professional" anything to have accurate knowledge about something, Goat.
You don't need to be a professional baker to know that if you set the oven to 500 degrees and put a tray of cookies in there for 15 minutes, they are
going to burn.
You don't need to be a professional road engineer to know that dumping some sand in a pothole isn't going to "fix" the road.
