Except in this instance, the conservative justices completely abandoned their "textualism" argument given the law in question was written by Congress to do precisely what they disallowed.

Almost all waters are “literally connected to each other” in a manner that’s clearly beyond anything Congress intended to regulate when they revised the CWA. It’s just a matter of how intimately connected.

I agree in the sense that global warming is about the temperature of the oceans, not the atmosphere. The oceans are essentially a very large thermal battery. I immediately know the article is trash the moment they start blaming global warming for how hot or cold it is today rather than broader weather patterns. The upper and lower bounds for temperature at a given time of year are far more dependent on geography. It'…

It's trivially easy to see that all this "record breaking" is just recency bias, not global warming. This makes no sense. Are they not just comparing numbers? Or do you suggest that when they compare numbers to see which number is bigger, they add a bit to the number from this year because they have a recency bias?

Data from the past is less accurate and incomplete.

That creates a bias for recent data even if the real atmospheric temperatures have not changed. We're forced to treat the data as the source of truth only because it's all we have, but we shouldn't assume the data is perfect. In statistics, picking out individual data points is about as silly as it gets.

Abnormal cold days are a sign of climate change too.

Hahah yeah at this point everything is a sign of climate change. That's my point. You win either way.

Global average temperature is not a well-defined statistical measure and can be surprisingly difficult to measure given large regional random and systemic variation in the measurement, including sampling effects. But, if you live near some mountains, you can look at them and compare to pictures taken 50 years ago and draw some conclusions about precipitation and temperature trends at the top of your local mountain ra…

what more do you need than a spreadsheet?

more generally, why would someone spend their time charting local temperatures manually… do you not trust the national weather service?

There are two sets of satellites that measure the temperature of the global troposphere, and have been doing so for over forty years. The data from one of them, UAH, is analyzed here.[0] It is increasing at 0.13C per decade, averaged over 44 years. [0] https://www.drroyspencer.com/2023/06/uah-global-temperature-...

Interesting that until Remote Sensing Systems revised their historical data six years ago, no warming trend was evident. How could they have been so wrong for such a long time? https://www.carbonbrief.org/major-correction-to-satellite-da... https://www.drroyspencer.com/2017/07/comments-on-the-new-rss...

RSSv3 showed warming, it's there on the graph.

RSSv4 corrected against ground data (calibration) and normalised for time drift and incident angle also showed warming .. more warming as prior post processing results had an incorrect transfer function.

As a point of order, their raw historic data has not been altered - instruments rarely directly produce values of interest, they must be calibrated against other sources to provide a transfer function between raw instrument product and final values of interest.

Bimetallic strips don't measure "tempreture" - they show the expansion of metals in tension.

They must be calibrated to show a "tempreture" relative to amount of bend.

Traditional aircraft altimeters don't directly measure height above ground, they are aneroid barometers that reflect the atmospheric pressure from a static port outside the aircraft. Calibration and barometric pressure on the ground are required to form a transfer function for height.

It’s supposed to be Congress’ job to do something, but unfortunately they appear to be useless.

I think it should be clear by now that the textualists are only interested in text that suits their interests (e.g. the first clause of the second amendment is just flavor text since 2013).

Funny how this claim can be made when they pull shit like this but not when they legislate from the bench for the right.

If we pretend the Supreme Court is partisan, which it is not but let's entertain that thought here, then the decision was bipartisan. Both the Left and the Right judged that the EPA was overstepping its authority.[1] >The court voted unanimously to reverse the Ninth Circuit, but split 5–4 on the rationale. The majority opinion, by Alito, introduced a new test to define wetlands, which reversed five decades of EPA rul…

> If we pretend the Supreme Court is partisan, which it is not but let's entertain that thought here.. I mean, that’s laughable, I don’t know how anyone can call the current Court non-partisan with a straight face. That doesn’t mean every decision is necessarily partisan, but multiple decisions over the past few years have been blatantly partisan, with Thomas and Alito especially making very little effort, if any, to hide it. I used to feel that the Supreme Court was the one of the few non-partisan institutions in our government, but the way this Court has run roughshod over stare decisis to effect change in the interests of its majority was more than enough to disabuse me of that notion. Everyone loves when decisions are going their way, consequences be damned, but the way those decisions get made matters, and nobody should be happy with the way the current court is choosing to act. It has set a really bad precedent for future courts, and has already done immense damage to its reputation in the eyes of many.

The climate denialism on this site is ridiculous, considering the average education and pay rates of the users on this site.

average education and pay have nothing to do with it. a lot of hn users are bazingapilled techno-opportunists. climate breakdown confronts two axioms for what is probably a sizable userbase of this site: - nothing (bad) ever (really) happens - advancement of technology and industry solves all problems they have no incentive to be any other way. because of the high pay and education, most of these people will be able…

Calling into question optimism and entrepreneurship can be a very existential question, I admit that believing the phenomenon is overblown and of the data dubious is very tempting given the mental weight it clears. But the irony for this population (me included) is that it’s the same as believing in afterlife to alleviate the existential dread of death, it’s religious thinking. People do great things without being death denialists, it should be the same without climate denialism.

That's not "recency bias". Rather than "recency bias", I suspect you meant that data from the past is less accurate and less complete, due to measurement technology, measurement techniques and record-keeping.

Most people on here (generalisation) spend more time on a computer than in nature. If you spend time in Nature it is very obvious what is happening. Look at the world from whence it came and where it is going.

Heating of our climate is but one thing.
