Reminder: what is happening now is the result of past emissions and will keep happening year after year no matter what. After humanity finally stops emitting greenhouse gases, it will not get better, it will just stop getting worse. The earlier we act the less bad the consequences.
US set for punishing temperatures as ‘heat dome’ to settle over country

#52The source the Guardian links to is showing the outlook for July 31 - August 4, while the embedded image and article appear to be talking about July 25 - July 31. Before noticing the dates I'd thought the article was simply wrong and was using outdated data, it's just that next week is forecast to be cooler than this week.
Edit: And then right after posting I notice the date range is actually embedded in the image, July 29 - August 2, Thursday to Monday. At least the first part of the article does seem to be mostly based on outdated data, the outlook now showing much cooler than the snapshot in the article for most of the same days.

It's quite sad that this forum, usually one of the most civil and thoughtful places on the internet, is full of climate change deniers with pathetic arguments that even they must see the issues with.
It seems like you're actually being uncivil and unthoughtful, and actually upset because other people have different viewpoints, which you are calling "climate change denial", when I doubt anyone here actually denies that the climate is changing.
Sorry bud, but it's not "unthoughtful" to discount your opinions. I, and apparently a good percentage of the site, have considered them, found them fruitless, and tire of the arguments.
Your beliefs are incorrect. You can think what you want of course, but there comes a point where nobody needs to care what you say.

In fact, if we stopped emitting entirely tomorrow, things would get much worse very quickly for a few years, due to the aerosol masking effect. Basically we're actually emitting so much that our pollution is blocking out some of the heat from the sun - remove the pollution and now we have all of the greenhouse gases we had before still in the atmosphere, but we're getting the full amount of heat from the sun. Explained much better here:

you gotta explain the logic to me that should make anyone less concerned about climate crises just because people also used to die of them 200 years ago. We're not reinventing any phenomena because we're emitting CO2, we're just putting the foot on the gas pedal, both literally and metaphorically. Same argument occasionally crops up during the pandemic. Yes, we've had them before, but that doesn't make this one any l…
Well, if the current events tell us we're in a crisis, were we also in a crisis a century ago? Two centuries ago? Three centuries ago? We can look in history books and see the same kinds of events happening back then. If they indicate a crisis now, don't they also indicate the crisis was happening back then?
You're arguing that it's not a big to deal to kick asteroids onto orbits intersecting with Earth's because in the past Earth also was hit by asteroids.

#56We have experienced the coldest winter since 2011 in the Southern Hemisphere (at least South Africa) this year. The summer was also warmer than average. I wonder what less conservative global warming forecasts would look like, and whether the winter this year will be average in US and CA.
"Global warming" involves extremes of temperature on both ends of the scale, and "coldest winters" are not inconsistent with that. Think about a pot of hot water vs. one that's boiling. The surface of the water in the boiling pot is not smooth, it has peaks and troughs. The level of some of those troughs will be lower than the level of the water in a less energetic pot. The situation with global warming is similar, a…
It is more than this, too. It is called climate change for other reasons, and that is because while the global, overall, average temperature will rise, local temps could drop, or even stay the same!
Say we have a 3C temp rise, global average. Some places could have a 10C increase, others a -5C decrease average!
Look at coastal areas, like British Columbia, while inland the temps drop quickly. Or the British isles.
Ocean currents bring warm water north, keeping these places warm, but the currents could reverse! Or vanish!
Now you have temp drops, but in a local region, even with overall 3C rises...
I guess my point is, localized events mean almost nothing. The true tragedy of climate change is that by the time we can really verify it is happening, it will already have happened.
And some areas will have incredibly dramatic climate changes, others almost none. Think 10C average warmer, including for heat waves.
Edit: just realised you sorta said this, just in a different way. Will leave this here regardless.

#57Is there an estimated timeframe for when people will start to experience the impact of the climate crisis instead of only hearing about it?
Dozens dead and more than one million people displaced by flooding in China https://www.washingtonpost.com/world/2021/07/21/china-floods...
One might almost say that the belly of the dragon will drip water.

No. Frequency of conditions intense enough to constitute ‘a disaster’ has gone up.

#59Where did the 'heat dome' term come from? Is it actually a new kind of weather phenomenon (the Wikipedia page is from this year) or just a new term the media has been (ab)using instead of calling it a heat wave as they would before?
Doesn't heat dome sound way more sensational?
Hard to convince people to take a wolf seriously with decades of crying about it. In fact, at this point, we are all voting for the wolf.

I think ca 2150 would be a reasonable non-cranky estimate, assuming current trends hold.
At that time, if things don't improve by a huge margin (like in : never before in human history; except maybe at WW2 levels), hundreds of millions of people will have moved away from their birthplace (taking the place of other who may or may not be happy with it, which may lead to "tension" between populations; see what happens today when a few refugees (yes, a few) reach the borders of Europe...) My understanding is…
Then I would kindly suggest governments stop encouraging people to continue reproducing at an unsustainable rate. Reversing overpopulation would make both mitigation and adaptation much more feasible.
