That's to be expected, the global variation over the last 2 decades has been about .2-.3 celsius. That's very difficult to notice, and basically completely swamped by local variations (what is called weather, not climate).

The thing is climate change is an almost perfect example of the boiling frog parable. It occurs over several decades, just enough to cause skepticism or feelings of "it's not changing so quickly".

See NASA's graph: https://climate.nasa.gov/vital-signs/global-temperature/

This rate however is probably almost without precedents geologically, save for extreme events like giant eruptions or something. It's hard for life to adapt this quickly, on top of the many other habitat pressures we've introduced. Also, there will be significant consequences for humans (which could be catastrophic and hard to predict if we don't limit warming to say 2C).

What frustrates me is that there's still significant resistance to not destroying our own home...

It's also important to realize that this isn't all "natural" skepticism and there's plenty of money being thrown around to spread FUD about the causes, severity, and consequences of climate change.

Skepticism isn't the problemj; blind belief is --- and there's plenty of money being thrown around to do that too.

I have trouble visualizing what form the catastrophe would take. The worst I can imagine is global famine, is that what we are talking about here? Or rather local famine, acting as catalysts to civil unrest, wars etc?

Basically, I think the climate debate gets fuzzy here. Granted, just like you say, it gets hard to predict, but given that, what makes certain temperatures a threshold for disaster?

If oceans get too hot, fisheries will collapse and wreck coastal communities. Sea level rise will make storm surges worse and make "once in a lifetime" events more common.

This instability will drive a migration of people inland, essentially as ecological refugees.

Given that it's such a small change... Surely this is not a problem for our generation. It definitely does not appear to be a problem that's worth destroying financial opportunities on a massive scale and enabling totalitarian governments in the current era.

The way I see climate change activism is that elites want to fix the climate at the expense of the lower classes of society... In a time when wealth inequality is at an all time high and without the consent of the lower classes. This is incorrect.

First, we have to fix inequality problem so that the pain of the transition will fall more or less evenly on everyone's shoulders... Then once this is the case, everyone should have more time to think about climate problems and we can expect broad support.

Of course, 'we' will all be long dead by then. I feel totally fine and morally justified in leaving this problem to a future generation. Most people in my generation have way too many concrete personal problems concerning their own survival in a week's time to worry about abstract problems such as the survival of the human race in a few hundred years.

...Not to mention that in a few generations' time, if we focus on maximizing access to opportunities, through the resulting innovation, we will probably end up with extremely efficient renewable energy which will be able to fight climate change far more effectively with no sacrifices necessary.

It seems literally like a no-brainer to me to just let the free market do what it does best in terms of innovation. Shut down government money printers and dismantle policies that are harmful to the free market and which centralize opportunities and create tech monopolies to control the masses. That's not the way. It needs to be done honestly.

What's the point of even allowing the human race to survive if it turns the global economy into a squid game and only the most dishonest, manipulative people will remain?

It's interesting you chose the boiling frog parable because it's a fallacy. Skeptics contend that climate change will not precipitate an abrupt catastrophe; rather, humanity will simply adapt to it.

To illustrate, the Earth's temperature has already risen by approximately 1 degree since the inception of industrialization, yet our lives have arguably improved significantly during this period. Would we willingly forsake the past century of human progress to revert the global temperature back by that single degree? This seems improbable, and yet it is a viewpoint advocated by certain climate change alarmists who propose concepts like degrowth.

Which notable people think we should go back to a pre-industrial age?

I’ve never heard anyone seriously suggest that. I don’t believe you’ve heard serious people suggest it either.

Why do we need to sacrifice living standards to control emissions?

Eh. I see what you are saying but have we felt the full effect? Do any of us have a perception of what was lost that would let us even make such a determination?

It's not alarmism to say we should take action to prevent out extinction. By your logic, people who call emergency services when a building is on fire are "alarmists".

There has literally NEVER been a problem anywhere near as large as climate change, including World War 2. If being concerned about literally the largest problem to have ever existed is 'alarmism', then your position is simply that it's impossible for anything bad to ever happen.

It's really not a big deal - humans will adapt to deal with the changes, or they'll go extinct and something else will evolve.

Sure, but I'd rather live in paradise than burn my house. In that sense nothing's a big deal, but it is for me. I believe we all deserve good lives.

The best adaptation to burning your house is the rational thought "Perhaps I should not burn my house". :)

It dreads me to think we so much lost contact with living well that many don't care anymore. I think the first step in the journey would be to stop the destructive culture of desperate consumerism, greed, consumption, overwork and ill-being. Maybe that's something we should be prioritizing alongside climate change, as a species. Living well in our homes, and as a community.

This is surely bait. Human extinction and 'not a big deal' in the same comment? Am I misunderstanding?
