Everything that has mass has a gravitational pull, so as the ice melts the gravitational pull it has goes down on a non linear curve, meaning the sea which is pulled by the ice will spread across the rest of the earth, increasing sea level rise.
There's a whole list of massive land areas below sea level... Some of them are reasonably unpopulated by humanity... For 100 million dollars and a few years of construction... humanity could flood a few of these areas and 100% CONTROL where this sea rise goes... Your statement is only true if humanity does nothing...
I usually think that a little extra heat will cause more evaporation and thus more cloud cover, and it will rain more in places that were lacking rain in the past. This would expand, or at the very least displace/replace, areas of plant life; more hot tropical rainforests. But then that isn't quite cataclysmic enough to be noteworthy.
You should’ve shown some concrete examples. From what I understand, according to the IPCC under a very high GHG scenario, sea levels are expected to rise up to 1m by 2100. You should show people a map of what that looks like. I was surprised when I did so.
Homes near sea front are not the most worrisome ones. Think about our chemical plants and nuclear reactors (ie. Fukushima [tsunami]). When a storm surge hits those the devastation will be huge. Do not buy or build anything that is less than 5 meters from current sea level. (Unless it floats, can go underwater, can be relocated easily, is meant to last only few decades...) Also sea level rise mainly affects only coastal areas (yea, there is huge suffering and losses, but still), but the worst impacts will come from food and fresh water securities. When our crops fail due to droughts or floods, we will have less to eat. Food prices goes up. When this happens in multiple areas at the same time (like it did happen in 2023, storages helps for half year or so), there is not enough food in the markets. And therefore hunger is the obvious result. The other result is for all losing parts of cumulated wealth. That leads to civil unrest and collapses like we have seen as a islamic revolutions or what happened in Syria. Water security is going off the cliff when mountain glaciers melts. These are the main sources pf water for 40% of Europians, 1,5 billion Asians, Rockies, Andies, and so on. These mountain glaciers might be mostly gone by 2050-2070. We are losing key ecosystems and key elements that supports our lives.
I love these videos and I am always following you. Thank you! However, I wonder what is Ben Shapiro doing in this video... Despite the irony about Aquaman which can be a good joke, I am not a big fan of his and he doesn't need any more PR, in my humble opinion...
It’s not Global Warming or Sea Level rise that has me worried (we can adapt to those things) it’s Ocean Acidification that is giving me Grey Hairs, All over the internet people talk about how Ocean Acidification is gonna make the planet almost completely uninhabitable by 2045 and while I know that’s most definitely an exaggeration it still has me worrying for my future and the future of my Family and Humanity as a whole.
Incorrect terminology. Because the ocean is alkali if more acid is added it moves to becoming neutral, so it is ocean neutralization not acidification. There, less to become scared about. You need to understand that these terms that climate alarmists use are meant to scare you, not inform you.
How coupled are GCMs to models of ice sheet dynamics? Do they consider these? I understand the uncertainties, but, to me, that means modeling an ensemble of possible models on ice sheets for each exogenous climate conditions posed by a GCM. Can climate models and their computational systems handle this?
I'm pretty sure that all modern GCMs would have some kind of ice sheet dynamics, but I think our most reliable simulations would come from dedicated (and more detailed) ice sheet models. You'd use simulations from GCMs of different scenarios as your boundary conditions. Of course, different ice sheet models have different assumptions in them (do we only include processes we've observed, or processes that may come into play in the future, for example) and different results - hence the massive uncertainty discussed in this vid.
I guess this shows you there's a bit of non-reversibility here, if you take land ice and melt it it flows into the ocean and makes the levels go up, but if we by some miracle managed to reverse climate change and the polar ice caps started to refreeze, refreezing ocean water into sea ice doesn't actually lower the level. We'd need to get that ice back on to land, which is an even harder problem than just cooling the planet off, which is in and of itself a big problem.
I actually don't know of any work looking at reversing ice loss - halting or slowing it asap tends to be what most focus on. that doesn't mean there aren't ideas about this, but given that water and ice plays catch up with the atmosphere, it would take a lot of work to reverse that freight train.
You can't 'reverse' climate change. Change just says it's moving, and nothing about the direction of movement. You need to pick your terms more carefully.
We have no idea but it could be a whole lot! Time frames are helpful as are the nuances of climate models which run hot. The extreme scenarios are not accepted as having much credence. 1.5° C and a foot of sea level rise is going to make the earth a much more amenable place for humans to live and thrive.
was such a treat joining forces with Ella (aka Dr Gilbz). check out the vid we made on her channel over here: th-cam.com/video/IsmAOoW8fx8/w-d-xo.html
Love this collaboration! Excellent video ✅
Sea level is rising about 3.5mm a year and has been for three centuries. It is not going to increase.
Love the collaboration with Dr Gilbz. Also, excellent role playing of the melting of ice shelves guarding glaciers. :-)
can't believe we left it this long to join forces!
Another great video from upu both! Thank you for being consistently wonderful :D Your videos always make my day, ClimateAdam
Awesome hbomber reference
When I think of the impacts of climate change I think we will suffer.
How can i contact you sir? I want to talk ..i m working for solutions regarding climate change and i need to talk to u too
Did not expect an hbomberguy reference in this, but props lol
Those that scoff at sea level rise (only a few centimetres) never consider ocean surge which has already seen some islands been abandoned.
Love the hbomberguy reference!

My guess is All of the Ice.
Edit: although possibly not if the thermohaline circulation gets shut down.

This would expand, or at the very least displace/replace, areas of plant life; more hot tropical rainforests. But then that isn't quite cataclysmic enough to be noteworthy.

Climate scientists said that by the year 2000 the Maldives islands would be underwater? Is that still a valid statement?

This is a great video, somehow having both of you collaborate makes it even better
teamwork makes the dream work!

I’m not shore, either. 🤦♀️
whatever happens, I can sea it's deeply concerning
She is dead right they do not know,any more than they can NOT for cast the future of the planets weather.
Very very hi... aprox 3-5 mm / 100y
Ummm i think 🎱🎱🎱
I think of over population. We will bake long before we drown.
What happens with 450 nuclear plants on the shores ?
We ain’t getting out of this one alive!

Your acting is award worthy!
only if the award is a Razzie!
In short, we're doomed...
