Changes in Atlantic currents

"climate change" has become the universal excuse for poor forest management policies.

Uh-huh... fuel load... right... years of drought, record high heat, and record low humidity have nothing to do with it.

BTW - good luck down under with your floods, fires, mouse and spider plagues. I'm sure it will be an interesting summer for you too.

Wasn't this the plot in the movie "Day after tomorrow"?

I saw an article and was left rolling my eyes. If defies logic.

As large swaths of ice began to melt from the ice sheets in North America, the sudden influx of previously frozen fresh water being dumped into the ocean prevented the heavier saltwater in the stream from sinking and returning to the equator, resulting in a weaker current.

So climate change is not real and COVID is not at all dangerous?

Who would have thought!

Umm, maybe I missed something, fresh water sits on top of saltwater……

Yes, you're correct.
Seawater [sea water is 1.025 gm/ml] is a little bit more dense than fresh water [fresh water is 1gm/ml], so it sinks beneath freshwater.
Cold water is heavier [more dense] than warm water, so cold water will sink below warm water.
When seawater freezes to form sea ice, salt is squeezed out, and moves down into the water. This means that sea ice is made up of mostly fresh water. The water just below the sea ice is saltier, and more dense than the water below. Because it is more dense, it sinks.
The water that sinks is replaced by surface water, that comes from areas closer to the equator, where it is warmer.
The cold, salty water sinks, to form an ocean current, that moves deep underwater toward the equator.
The surface water, that replaces the sinking water, forms an ocean current, that moves from the equator, toward the Arctic and Antarctic.
So, ocean currents are formed because dense water [cold and salty] sinks.

We have become a crisis driven society, that’s for sure. Politicians need us to believe that but for them, we are all doomed. While many of us feel, that just the opposite is true. And, I am okay with being ridiculed for thinking that. It won’t change me.

I don’t think politicians set the agenda. The public does.

Large swathes of people see climate change as an issue. The rise of the Green Party in many countries is testimony to that. Politicians tend to then eventually reflect the public mood.

That's my point - how would it prevent the heavier saltwater from sinking?

Maybe so, but I think politicians execute on agendas in highly divisive ways to maintain and increase their power. I often can't believe how much of the public buys into it -- on both/all sides -- without any sort of critical thought.

It's called dilution.

Not being droll, just remembering that in a post a few weeks ago you were also all indignant about how much water people use for personal hygiene, and how you can get buy on 2 tablespoons a month.

I’m pleased as the OP for this pretty good discussion about climate change.
Climate has always changed - the geologic record shows this clearly.
As another poster noted, currently it is the rate of change that is most concerning.
It seems incontrovertible that since homo sapiens started our Industrial Revolution, we have measureably changed the composition of our planetary atmosphere.
Can human civilization in its current form, developed since we changed from wandering hunter/gatherers to sedentary agriculturists continue robustly considering all the extra mouths we have (and will have) to feed?
Just an old offshore oil field engineer who has worked from the polar ice pack to tropical waters who is alarmed in all the changes I’ve seen happen to the planet’s surface during my adult life.

Well the same can be said for scientists. They need issues to study. Without issues to study they won’t need funding…

Says the man who denies being droll..
whose countrymen constantly post on here how they can't survive without at least 20 minutes under the shower..
No wonder Californian vegetation is so dry as each year you have to drill deeper for ground water for showers, sprinklers and swimming pools as the native plants dry off above.
There's to many links to the mess that they've made of the water situation to post, yet they're trying to promote their 'Green Agenda' with their Renewable Energy policies.. wrong end of the stick methinks..
Man and Nature can survive without electricity (cold showers ) but take away water and he's screwed.. 40 million times.

As to my 'fixated agenda'? I'm flattered you know so much about me... from only my 350 or so posts.

Its not the quantity.. its the quality of the context..

This all boils down to the elephant in the room that no one seems to want to address….
