So the climate was changing at least 325 million years ago.

How many of those 4.5 billion years were humans burning fossil fuels? It’s entirely possible our way of living is having an impact on climate. If you can’t comprehend that maybe you’re the idiot.





There’s a growing massive ball of energy radiating in the center of our solar system that has much more to do with our climate than any other known variable.

In the early Mississippian Era, Kentucky and most of the contiguous US lay at the bottom of a shallow ocean.

No, it's definitely happening.

Talk to the folks in Charleston.

quote:

The sea level off South Carolina’s coast is up to 10 inches higher than it was in 1950.1 This increase is mostly due to ice melt, and it’s causing major issues. In the 1970s the city of Charleston experienced an average of 2 days of flooding per year, but now it is projected that the City could experience 180 days of tidal flooding by 2045.2 Across the state, flooding has increased 75% since 2000.3 Because of its low elevation, Charleston’s medical district is exceptionally vulnerable to flooding. During flood events, areas of MUSC become inaccessible, making it impossible to evacuate or move patients.4

There are already over 90,000 properties at risk from frequent tidal flooding in South Carolina.5 The state is planning over $2 billion in sea level rise solutions, which include beach renourishment, seawalls, drainage improvements, and raising roads.

So the megalodon was born 40ft long?

The earth was a lot smaller back then, as well. 4.5 billion years of an expanding earth will create changes errwhere.

FWIW there is a spot just off the main highway running into Ft Benning, Ga where a part of the prehistoric era (60-80 million yrs best guestimste) coast is uncovered. Area about 30 x40 yds...sandy and loaded with ancient sharks teeth. I went out there twice for a class and found 15-20 teeth from a goblin shark in roughly 10 mins.

But years looking for sharks teeth at Myrtle Beach/Panama City yield nothing...go figure
LOL

Today I learned there was a Mississippian Period

Mississippian wasn’t 325 million years ago. More like 2k years

From your link.

quote:

While there are four main causes of sea level rise in South Carolina, land sinkage is the largest contributor.7 Because the land is getting lower each year, due to a process called subsidence, South Carolina is particularly vulnerable to an increased rate of sea level rise in the future

The question is not if man has had an impact the question is to what extent and how?

If you are worried about CO2 you are worrying unnecessarily. CO2 does not correlate with temperature rise. In fact it correlates with climate that has lower highs and higher lows, i.e, temperate climate. And that is exactly what the un-altered raw NOAA data shows from the last 125 years.

As CO2 concentrations increase the world becomes greener. A greener world is more temperate. For example we don’t see droughts in the Midwest like we did in the middle of the 20th century. That’s one of the benefits of more CO2. More plant food which leads to greening which leads to more temperate climate.

This reminds me I visited my sister in laws parents in Munster Texas at a farmhouse on the lake. The place is loaded with Nautilus fossils and millions of other prehistoric fossils.

Science, Bro

The first arguments for the Expanding Earth theory arose from the simple exercise of sliding cut-out continents around model globes. Scientists were irked to discover it was impossible to piece Pangea back together on a full-size Earth without getting inexplicable yawning gaps and overlaps along the edges of the continents. But, if you modeled the continents on a sphere about 60 percent smaller than the Earth, they fit together seamlessly.

The Expanding Earth, in addition to solving the continents jigsaw question, could explain away another geological mystery: the strange fact that the ocean floor is billions of years younger than the Earth’s land.

1. Many scientists think that the earth's core is cooling off. However, matter that cools off shrinks, not expands.


This is so wrong.

When ice cools down it expands.

It’s easily demonstrated by filling a glass with ice and water to the brim.

As the glass gets cooler, the ice turns to water and overflows the glass, proving it expands. Just like the Earth.
