The Climate Change Thread

This summer has actually been the coolest summer in central Texas in a few years. Last year it was like 30+ straight days of over 100 but it's been mostly in the 95-99 range this summer.

The climate crisis is causing the length of each day to get longer, analysis shows, as the mass melting of polar ice reshapes the planet.
The phenomenon is a striking demonstration of how humanity’s actions are transforming the Earth, scientists said, rivalling natural processes that have existed for billions of years.
The change in the length of the day is on the scale of milliseconds but this is enough to potentially disrupt internet traffic, financial transactions and GPSnavigation, all of which rely on precise timekeeping.
The length of the Earth’s day has been steadily increasing over geological time due to the gravitational drag of the moon on the planet’s oceans and land. However, the melting of the Greenland and Antarctic ice sheets due to human-caused global heating has been redistributing water stored at high latitudes into the world’s oceans, leading to more water in the seas nearer the equator. This makes the Earth more oblate – or fatter – slowing the rotation of the planet and lengthening the day still further.

Longer days? Yes, sign me up! I always needed more time in the day. A few milliseconds more sleep sounds grand!Who would have thought this?

Scientists sound the alarm after new research points to growing invisible threat putting coastal cities at risk: 'We need very dramatic action'
A new study that accounts for seawater intrusion between ice sheets estimates that other projections about future sea level rise could be too modest.
www.thecooldown.com
“As detailed by the Guardian, researchers used computer models to analyze how ocean water intruding into ice sheet cavities impacted melting rates. They believe this could create a "tipping point" where the sheets lose ice much faster than expected.
"[Seawater intrusion] could basically be the missing piece," study leader Dr. Alexander Bradley told the news outlet. "... And there's a lot of evidence that when you do include it, the amount of sea level rise the models predict could be much, much higher."
The Guardian also highlighted a previous study that suggested seawater intrusion could cause some Antarctic ice sheets to lose ice around two times more quickly. The latest findings were published in the journal Nature Geoscience“.

Two very, very stupid men.
www.theguardian.com
“Donald Trump and Elon Musk both made discursive, often fact-free assertions about global heating, including that rising sea levels would create “more oceanfront property” and that there was no urgent need to cut carbon emissions, during an event labeled “the dumbest climate conversation of all time” by one prominent activist.
Trump, the Republican US presidential nominee, and Musk, the world’s richest person, dwelled on the problem of the climate crisis during their much-hyped conversation on X, formerly known as Twitter and owned by Musk, on Monday, agreeing that the world has plenty of time to move away from fossil fuels, if at all.
“You sort of can’t get away from it at this moment,” Trump said of fossil fuels. “I think we have, you know, perhaps hundreds of years left. Nobody really knows.” The former US president added that rising sea levels, caused by melting glaciers, would have the benefit of creating “more oceanfront property”.
‘The dumbest climate conversation of all time’: experts on the Musk-Trump interview
Trump talked about ‘nuclear warming’ while Musk said the only reason to quit fossil fuels is that their supply is finite

Rising ocean levels doesn't create more ocean front property. It actually creates less since that would mean that the above water amount of land would be decreasing.Two very, very stupid men.

It would create different ocean front property though.
trump rarely has basic knowledge or depth about the subjects he talks about

It looks like climate scientists were all full of crap. Historically speaking, the Earth is cold. A warmer climate than we have now is normal.
A lot of people are trying really hard to spin this but the reality of the study is undeniable.

Right. The new study confirms climate denialism! And climate scientists carry no weight! Oh, wait, it does no such thing….BTW, paleoclimate studies evolve with new information. In fact, believe it or not, that’s the way all science works.
Stolen from Quora: “The foundation of science is that a theory can never be proven. We never know if some new data will come someday and falsify a theory. A good theory that has a lot of evidence for it is accepted by most scientists as the best theory that we know of so far. But they can never say for sure that it is true”.
(News flash: scientists revise understanding of paleoclimate changes, in response to new data!)
————————————————————————————————————————-
“If you're studying the last couple of million years, you won't find anything that looks like what we expect in 2100 or 2500," said Scott Wing, a co-author on the paper and a curator of paleobotany at the Smithsonian National Museum of Natural History. "You need to go back even further to periods when the Earth was really warm, because that's the only way we're going to get a better understanding of how the climate might change in the future."
The new curve reveals that temperature varied more greatly during the past 485 million years than previously thought. Over the eon, the global temperature spanned 52 to 97 degrees Fahrenheit. Periods of extreme heat were most often linked to elevated levels of the greenhouse gas carbon dioxide in the atmosphere.
"This research illustrates clearly that carbon dioxide is the dominant control on global temperatures across geological time," Tierney said. "When CO2 is low, the temperature is cold; when CO2 is high, the temperature is warm."
The findings also reveal that the Earth's current global temperature of 59 degrees Fahrenheit is cooler than Earth has been over much of the Phanerozoic. But greenhouse gas emissions from human-caused climate change are currently warming the planet at a much faster rate than even the fastest warming events of the Phanerozoic, the researchers say. That speed of warming puts species and ecosystems around the world at risk and is causing a rapid rise in sea level. Some other episodes of rapid climate change during the Phanerozoic have sparked mass extinctions.
Rapidly moving toward a warmer climate could spell danger for humans who have mostly lived in a 10 degree Fahrenheit range for global temperature, compared to the 45 degree span of temperatures over the last 485 million years, the researchers say.

Earth has been and can be warmer than it is today, but humans and animals can't adapt fast enough to keep up with climate change, a new study finds.

Me personally, the temperature of the earth does not factor in at all in my desire to have cleaner air, water, and soil. I just like having cleaner air, water, and soil regardless of the earths temperature.

I've said this all along. Keeping our oceans clean and reefs healthy is my biggest concern.

Temperatures in Gulf waters is a factor.

Duh, no one lives in the ocean, so it's a NIMBY issue. Nobody gives a **** about anything that doesn't impact them right here and now.

My dad told me that when he was in school a teacher said to the class "The solution to pollution is dilution." Just got to spread that plastic around and we'll be right as rain.
