Your own source affirms the other person's point, not yours; switch to the table view and sort by absolute change.

It really doesn't - my source shows average summer temperatures (Th - Tl / 2). This does not say that those regions are experiencing high temperatures that are that much warmer, but that on average (including overnight lows) they are warmer.

I'm not talking about global, look at individual countries:

- Andora (5C/9F)

- Montenegro (5C/9F)

- Japan (4C/7F)

- Italy (4C/7F)

- Spain (3C/5.4F)

Even with current rates I think we'll easily hit a 20F increase in several regions.

Pretty sure global warming is referencing the global affects, not regional ones. You can't make a global argument based on local temperature increases just like you can't make an argument that global warming is causing cooler summers based on the numerous regions that have experienced cooling in the same reference period. Also these are average temperatures increases, not summer high temperature increases.

So your argument that this statement by them: "If you live in a region that usually was 90F in the summer and is now >110F regularly, that’s going to cause problem." is hyperbole, then? Okay, going with that, what temperature range would you find credible, as to describe a region that is seeing wilder swings in summer highs?

Somewhere on the order of 1-2C if you start from the 1850s.

Their argument is not predicated on a 20F+ temp rise globally; their argument is about regions.
alexk307 · 8 days ago
Most of the increase in local temperatures are overnight lows in the Winter. I'm not sure there's any peer-reviewed mechanism to suggest that daytime Summer highs will increase 20F+ due to greenhouse gases in any parts of the world.

The argument isn’t that the whole earth becomes inhospitable. But that certain regions do, and the rest will have their climate differ drastically.

If you live on the coast and the water level rises, your home is inhospitable, even if someone 100mi inland is fine.

If you live in a region that usually was 90F in the summer and is now >110F regularly, that’s going to cause problem.

There isn't enough fossil fuels in the ground for us to burn to cause a 20F+ increase in annual summer temperatures globally...

In the reference period 1999->2020, the instruments used by NHANES to track this data changed at least 3 times, they don't account for other changes to the general population that increase bicarbonate levels in serum (i.e. Number of obese Americans rose by ~40% in the reference period [1]). I'm not entirely convinced that using a proxy for C02 levels that can be confounded by a multitude of other health conditions that are common in the American population is a good way of going about this.

alexk307 commented on How can England possibly be running out of water?   theguardian.com/news/ng-i... · Posted by u/xrayarx

> As climate breakdown accelerates, rainfall patterns are changing fast, and water will increasingly become less available at certain times of year. As Sir David King, a former UK chief scientific adviser who chairs the Climate Crisis Advisory Group, says: “Drought in England is no longer a warning. It is a clear signal that climate collapse is unravelling our water, food and natural systems right now.

Rainfall over all of the UK has been increasing since 1840 accord to the Met Office [1]. How is a drought a clear signal of collapse if they've been happening since before the industrial revolution? [2]

Ah fair call out about it being a convective storm, but those have even more evidence of worsening relative to climate change.
alexk307 · 7 months ago
Not according to the IPCC:

> Climate models consistently project environmental changes that would support an increase in the frequency and intensity of severe thunderstorms that combine tornadoes, hail, and winds (high confidence), but there is low confidence in the details of the projected increase.

The models project it, but there is currently low confidence in the increase.

This study from the University of Reading found that severe turbulence has indeed increased significantly and measurably over the last 40 years: https://research.reading.ac.uk/research-blog/2023/06/28/avia...

But that's not what the paper says. It says Clear Air Turbulence (CAT) has gotten worse, not all types of turbulence. In this case, the flight flew through a convective storm.

Even so, the paper says there's been a 0.2-0.3% change in CAT:

> The largest increases in both absolute and relative MOG CAT were found over the North Atlantic and continental United States, with statistically significant absolute increases of 0.3% (26 hr) and 0.22% (19 hr), respectively, over the total reanalysis period.

Would you like to refute their claim?

Climate change causing turbulence increase is well acknowledged https://www.bbc.com/future/article/20240524-severe-turbulenc...

alexk307 · 7 months ago
That paper has nothing to do with the incident in question. You're referencing a BBC article that references a paper stating that Clear Air Turbulence is getting worse [1]

> Turbulence is unpleasant to fly through in an aircraft. Strong turbulence can even injure air passengers and flight attendants. An invisible form called clear-air turbulence

But in the incident in question, the plane flew directly through a convective storm.
