Meanwhile, as expected, we're failing to take the drastic action that would be necessary to actually meet emissions goals. It is now inevitable (barring some miraculous scientific discovery) that the future will be several degrees warmer, with more intense precipitation and drought. I do atmospheric science research, and looking at the high-end RCP8.5 and SSP5-8.5 scenarios is...disturbing.

The current president is pushing countries for MORE oil production.

What does that say?

It’s says we haven’t done enough to introduce alternatives to oil and there’s a country destabilizing the world because they have a weak ego. The worse thing we can do is bring in another thin skinned childish GOP idiot to grind our world further into the ground.

I'm not an expert on that, but huge climate migration is expected by mid-century already - I've seen estimates of anywhere from ~150 million to ~1 billion. In general, the frequency of extremes will be increasing gradually but consistently. These changes would typically include more intense and/or frequent extreme precipitation and heat waves; and even if overall precipitation totals stay the same or increase, it being delivered in these very intense extreme events with less light and moderate rain in between will increase the likelihood of drought. Rapid intensification of hurricanes/typhoons has increased as well, and will likely continue to do so in the future. So that would be an influence in many tropical and subtropical regions. I would worry about the greatest danger for short-term catastrophic changes being in regions that already experience extreme drought, fire, life-threatening heat, or monsoons, all of which stand to be intensified by climate change. Anyway, as for a specific time frame - I don't have an answer beyond...it's already becoming a problem, and will only get worse over the next few decades.

To add to this, we will see sea level rise over the next century that will force the majority of the globe's population to go somewhere else or invest in expensive infrastructure projects like massive sea walls. The mass migrations will strain, and in some places break, food supply chains. There is likely going to be massive social upheaval to accompany all of this.

On one somewhat bright note, we have likely avoided a hothouse Earth, where a feedback loop begins and the planet becomes too warm to support human life. This also assumes that our estimates for methane in polar regions is somewhat accurate.

I can already see it now, the propagandists are going to twist this data to their audiences as "Look, there's no more or less rain than before! Checkmate!" and those of us who understand the issue are going to need a 3rd hand to facepalm.

I'm (slightly) more in the realm of climate (paleoclimate and glaciers are more my thing). There's no specific time. It's more of a spectrum of fcked than a threshold of fcked ... if that makes sense. While there are physical thresholds in the climate system, like with ice sheets and the biosphere, how we're impacted isn't concrete.

Here's what I tell people: the longer we delay action, the worse the climate crisis will get. It means two things that are very important to understand:

  1. The climate crisis will get worse if actions are not taken. Life will increasingly become more uncomfortable and certain weather events will become more dangerous/deadly. It won't be the end of the world or life as we know it, but it will be fucked.

  2. We can always prevent the worst from happening. By taking action now or later, we can make the climate crisis less fcked in the future. Though some things might not be reversed, we can still make a things better relative to what they could be.

One more thing: everywhere is a climate sensitive area. Be prepared.

Seconding this! It's not "in the year 2050, all the shit will hit the fan." It's "everywhere will be getting a little more extreme every decade, on average." There are various extreme thresholds (too hot or cold, wet or dry) beyond which human life cannot thrive. The point of "fcked" in a given region would occur when the conditions move beyond that threshold. This is why regions where humans already live close to that climatological threshold - deserts, vulnerable coastlines, dangerous monsoon regions - will be some of the first to go.

Yeah, as someone working on a Conservation Ecology degree and going into fieldwork with all manner of critters, the effects of the unavoidable climate change we're staring down on ecosystems worldwide will be horrific. Any plants or animals that are not suited to the rising temperatures (often species that are already threatened in one way or another) will have a much harder time in the wild. Think of images of the polar bears on melting bits of ice in the Arctic, reports of escaped pet snakes gorging on every alligator egg they can find in the Everglades, the breaking news concerning the Alaskan snow crab population completely collapsing in the last two years alone.

Our native wildlife can't compete against everything humans are throwing at them, and the crabs are just the start. I can assure you there will be many more from where that came from, all over the world, because we as a species are hellbent on destroying this entire planet so severely we'll have to fuck off to Mars in the end or something.

I went into this degree because I want to help save the most critical and vulnerable pieces of our ecosystems, to keep us and everything else out there in the wild healthy and happy. At least I know now I'll have no shortage of demand for what I do.

Some progress is being made. Saw an article that we had just 1% increase in emissions this past year.

Oh good! Hopefully if this continues and accelerates we’ll at least be able to avoid the worst-case scenario of constant/increasing fossil fuel use throughout the 21st century
