The world’s oceans are extremely hot. We’re about to find out what happens next.

EXCERPTS: On Wednesday June 14, the surface of the North Atlantic Ocean reached an average temperature of 73 degrees Fahrenheit.

That may sound like a pleasant day at the pool, but it’s actually a record high, and it will have global consequences. The average for this time of year, over the past three decades, is 71 degrees Fahrenheit. That two-degree difference reflects a gargantuan amount of extra energy stored in the ocean. The Atlantic has been riding a wave of extreme heat since last year. And as summer sets in, the temperature will climb.

“This is an incredibly unusual year,” said Gabriel Vecchi, a climate scientist at Princeton University. “A warm Atlantic tends to have a lot of global influences.”

Atlantic Ocean surface temperatures affect rainfall and storms in Brazil, India, the Sahel region of Africa, and the southwestern United States. Hot water is also the fuel for hurricanes, which need the sea surface to be at least 79 degrees Fahrenheit to form. Higher temperatures boost the octane rating of this fuel, leading to more powerful storms. They can also diminish stocks of fish, which feed 3 billion people.

And it’s not just the Atlantic; oceans all around the world are seeing stunningly high average temperatures right now. On the other side of the globe, the Pacific Ocean surface is also heating up as it enters the El Niño phase of its cycle. Together, these phenomena are poised to push the planet’s temperature to new highs.

[...] there’s evidence that a reduction in air pollution over the past half-century had an unexpected side-effect: Since the end of World War II, sulfur and nitrogen aerosols from the tailpipes of cars, smokestacks of ships, and chimneys of factories have been drifting over the North Atlantic from the United States and Europe. That helped keep the Atlantic cool.

“Aerosols shut down sunlight. That sunlight is deflected before it reaches the surface of the ocean,” said Hiroyuki Murakami, a scientist at NOAA studying variations in the Atlantic Ocean. “If we increase aerosols, we expect cooler sea surface conditions.”

But as cities filled with toxic, dirty air, citizens on both sides of the pond clamored for tougher limits on air pollution. This led to regulations that reduced aerosols over the Atlantic, which in turn led to more warming at the surface of the ocean. A new regulation in 2020 that drastically limited sulfur from shipping may also have played a role... (MORE - details)

Climate activists changing their tune again. It wasn't too many years ago that warming oceans were supposedly the result of greenhouse gas pollution.

As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea level.

Now suddenly, it's the result of less pollution? Activists trying to stay ahead of their own lies.

That is so true - you should post it on Truth Social - if you haven't already done so.

You live in a strangely black and white world, where supposedly everyone who disagrees with you is diametrically opposed to everything you believe in.
I don't do social media, and wouldn't be on Truth Social, even if I did. I'm not a sheeple for either side. I find that people who march in lock-step with one political ideology are those who can't be bothered to think for themselves. Much easier to be told what to think, I suppose.

You think a group of people "liars" are trying to deceive you .. let's play 'spot the lie'..



Truth or lie?

Suddenly? It's been known for quite some time.

From https://en.m.wikipedia.org/wiki/Stratosp..._injection

Hughes patented introducing [edited aerosols] something similar to promote cooling .. it wasn't exactly new even then (so how did they get a patent?)

Quote:The method was patented by Hughes Aircraft Company in 1991, US patent 5003186.[147] Quote from the patent:

    "Global warming has been a great concern of many environmental scientists. Scientists believe that the greenhouse effect is responsible for global warming. Greatly increased amounts of heat-trapping gases have been generated since the Industrial Revolution. These gases, such as CO2, CFC, and methane, accumulate in the atmosphere and allow sunlight to stream in freely but block heat from escaping (greenhouse effect). These gases are relatively transparent to sunshine but absorb strongly the long-wavelength infrared radiation released by the earth."

    "This invention relates to a method for the reduction of global warming resulting from the greenhouse effect, and in particular to a method which involves the seeding of the earth's stratosphere with Welsbach-like materials."
