It's just another feature of climate change. The change in ocean currents can bring 'cold water' into areas of water that has already been heated, with disasterous effects. The reason for the link is to keep people appraised of current considerations. The effects of climate change can be far reaching. This was one effect that I had not considered; I was aware of the possible AMOC disturbance in the North Atlantic as a possible outcome.

How does surface heating bring cold, dense water up from the depths?

 

[BridgeSmith]

It's just another feature of climate change.

So now any climate event, even one that results from too much cold, is our fault? I thought our actions were releasing too much CO2, and that was causing warming of the planet. How are we suddenly responsible for a "cold water event"?

 

[dik]

Substantially...

The cold 'fresh' water from the melting arctic and antarctic glaciers does this.

"The melting of Antarctic glaciers has significant effects on water circulation. As glaciers melt, they release large amounts of cold freshwater into the ocean. This freshwater is less dense than the surrounding saltwater, which can disrupt the normal patterns of ocean circulation.

Abyssal Ocean Overturning: The melting of Antarctic glaciers can slow down the Antarctic overturning circulation, also known as abyssal ocean overturning. This circulation is responsible for flushing nutrients from the sea floor to fish near the surface. A study published in the journal Nature found that if the world continues to burn fossil fuels and produce high levels of planet-heating pollution, the Antarctic overturning circulation could slow down by 42% by 2050.

Atlantic Ocean Circulation: The melting of glaciers in Antarctica and Greenland influences the circulation of the Atlantic Ocean. As massive amounts of cold glacial-melt water enter warmer ocean waters, it slows down ocean currents. This can have far-reaching consequences, such as changing weather patterns worldwide, affecting fisheries, and increasing the frequency of destructive storms and hurricanes.

Sea Level Rise: As ice on land melts, the runoff significantly increases the amount of water in the ocean, contributing to global sea level rise. This can further impact ocean circulation, as the increased volume of water can alter currents and affect the distribution of heat and nutrients in the ocean.

In summary, the melting of Antarctic glaciers affects water circulation by disrupting ocean currents, slowing down abyssal ocean overturning, and contributing to global sea level rise. These changes can have significant consequences for marine life, weather patterns, and coastal communities around the world."

Bruh, you're back on sea level rise. Sea levels have already risen 410 feet and didn't cause any mass extinctions. There is only potential for another 50 feet or so.

You argue by ignoring history and facts and that's not fair to the rest of us.

Part of China's carbon footprint, and it's slowly sinking into the 'mud':

"Both studies have shone a light on some of the unexpected effects of urban development. But the Chinese research in particular has highlighted just how rapidly China's cities have developed and the scale of urban expansion in the city.

We can turn to one material, above all others, that has supported this growth: concrete, the second most used substance on earth after water.

During the first 15 years of the 21st Century, China accounted for nearly half the world's total urbanisation. Housing, airports, roads, water supplies, waste treatments, power stations and more have been constructed at astonishing speeds – in one example during the Covid-19 pandemic, the Chinese authorities claimed to have built an entire new hospital in just 10 days. China has been adding nearly two billion sq m (21.5 billion sq ft) of floor space to its cities every year – equivalent to creating an urban area the size of London."

Dik, what is the relevance of your last post?

 

[dik]

Just showing that concrete is a big contributor to carbon footprint, and that China is using massive amounts of the stuff...

Is that included in your per capita emissions comparisons?

 

[JoshPlumSE]

Is that included in your per capita emissions comparisons?

Almost certainly not. I believe most of the CO2 reporting is based solely on ENERGY production. So, power plants, cars, trucks, et cetera.

 

[dik]

Most likely. The CO[sub]2[/sub] per capita is based on the country total output. Not just energy production... the CO2 that China produces in making knick-knacks for the rest of the world... is included.

[TugboatEng]

Most likely? That means you don't know.

I don't know if any knick knacks that produce CO2 during their production. Their CO2 cost is strictly tied to the energy required to produce it. Concrete is the exception as it does produce CO2 during production.

It will be interesting if these events intensify over time...

1996 is so far away now. In 1996 Hollywood was able to make an entire movie about weather "Twister" and not mention climate change once. Today, they can't even make a movie about Barbie without seeding it with climate change.

 

[GregLocock]

To be fair the article doesn't mention global warming or climate change (at least on a search). Dik's posting about weather again.

Cheers

Making windmill less harmful

"Wind turbines can pose a deadly risk to migrating birds, but there are ways to dramatically reduce crashes."

Dik -

Thanks for that interesting and informative article. It was a little long, and it took a while to get going, but the crux was the following:
a) Wind Power turbines tend to kill a lot of birds.
b) Painting stripes on the turbine tower helps, So, does painting one of the blades black. The suggestion is that they reduce fatalities by 70%.
c) Also, adding an artificial "hiss" to the tower could better alert birds to the danger.
d) Apparently birds are not very good at avoiding obstructions while flying. Their eyesight is designed differently than humans. And, their evolution means that they don't generally expect to fly into something when they're flying high in the air.

AI use...

"Artificial Intelligence (AI) is not just a futuristic concept; it's a critical tool shaping the present, especially in the field of Earth Observation (EO). This is particularly evident in Copernicus, the Earth Observation component of the EU Space Programme, where, more and more, AI algorithms are employed to process the extensive data streams from Copernicus satellites. This marriage of machine intelligence and big satellite data is enabling a wide range of applications across various domains. From rapidly identifying environmental changes like deforestation or urban expansion to monitoring air quality and ocean temperatures for climate research, the use of Copernicus data with AI is transforming our understanding of the Earth’s surface in unprecedented ways.

Most of the AI algorithms have been demonstrated to have severe biases. They won't be useful for this.
