From atmosphere researchers, I know what's going on (and how much we really know and how much we really don't know) about the climate change itself - but not with all the political aspects of possible reactions to it.

My own bid is investment in energy-efficient technologies, water-efficient farming, resilience and adaptiveness.


I always thought nuclear and genetic modification of crops and cattle was the way forward. Think about genetically modifying cows so their farts don't contribute to greenhouse gasses and adding genes to yeast to make food instead of alcohol. It's small stuff that might go a long way. Also there has been interesting research into extracting uranium from sea water for an almost infinite energy supply.

Obviously the green brigade are against stuff like that sadly which I find ironic. They're far more interested in making the most impractical methods of energy production they can think of........and don't want to lift a finger to build it.....building it is just for the peasant that live outside the city. It's up to the underclass of tradesman and engineers to put in those 12 hour days while also having their cars confiscated because if a millennial can take her electric scooter into work in the middle of London then surely those construction workers can take their electric scooters 15 miles into work right?

Yeah. I just ignore climate doomers for the most part. Unless they come up with good advice for a change they're not worth listing to lol.

If you mean nuclear energy then yes, I have a similar opinion.
Genetic modification is not magic and I won't pretend to know what is possible and at what cost - but I've read about more low-tech ways of reducing greenhouse cow farts, like this: https://www.dailymail.co.uk/sciencetech ... burps.html

I think the whole climate change doom thing is unrealistic at best. Even if the water levels rose several miles I'm sure humans would find a way to survive. Humans are crafty, self-destructive, but crafty. I don't think the extinction of the human race even if say by some it rose up by miles. Which almost certainly won't happen. Unless like Th water beneath the surface leaked out but yea that's very unlikely. I read a sci-fi novel based on the subject.

Water levels won't rise more than about 70 m (230 feet) because there will be no more ice to melt.
Rising these 70 meters will likely take millenia but a lot of ice caps mechanics is not yet well explored.
A rise of about one meter is possible in this century.
Changes in weather patterns (droughts, floods, storms in unusual places) are likely to happen in various places.

I would call it problems but not doom.

Is there any weather phenomena that isn't "climate change"?

High rainfall, low rainfall, floods, drought, hurricanes, extreme cold, extreme heat.

It seems like every weather phenomena is made to fit "climate change".

Greenland's main glacier is growing, and that's bad news ...

When a glacier increases in mass it's bad news, if a glacier melts it's bad news.

Every weather change is somehow bad news?

El nina is weather change

submerged islands is a problem that can't be ignored

That isn't what that article said (Nat Geo's wording is a little bit funky, probably to get people to click on it). This is the essence:

Quote:
This reverses the glacier’s 20-year trend of thinning and retreating.
Quote:
despite the fact that this particular glacier is growing, the whole Greenland ice sheet is still losing lots and lots of ice. Jakobshavn drains only about seven percent of the entire ice sheet, so even if it were growing robustly, mass loss from the rest of the ice sheet would outweigh its slight expansion.
Quote:
on average the air and sea are warming, and that means retreats are always going to be bigger than advances


The point is outlet glaciers (ice streams) aren't always on 'runaway' retreats. Sometimes some of them will regain some mass, but overall the continental ice sheet is losing more ice than its gaining. (I'm a Glaciology graduate student)
