There's a Heatwave In the Sea and Scientists Are Worried (bbc.com) 115

An anonymous reader quotes a report from the BBC: The month of June and the first few days of July were hotter than any in recorded history, according to the World Meteorological Organization (WMO). Residents in the south of the US and southern Europe have been enduring sweltering temperatures, bringing excessive heat warnings, wildfires and plummeting air quality. However, records are not just being broken on land -- but in the water. Global ocean sea surface temperatures were higher than any previous June on record, according to a report by the Copernicus Climate Change Service, with satellite readings in the North Atlantic in particular "off the charts." Last month also set a record at the US National Oceanic and Atmospheric Administration (NOAA) for the biggest difference between expected and actual sea surface temperatures. Water temperatures around Florida, in particular, have been particularly warm. Scientists have also been tracking a large ongoing marine heatwave off the west coast of the US and Canada since it formed in May.

While the heatwave has since lessened in the north-east Atlantic, according to non-profit science organization Mercator Ocean International, another in the western Mediterranean now appears to be intensifying, particularly around the Strait of Gibraltar. This week, sea surface temperatures along the coasts of Southern Spain and North Africa were 2-4C (3.6-7.2F) higher than they would normally be at this time of year, with some spots 5C (9F) above the long-term average. Extreme marine temperatures have also recently been observed around Ireland, the UK and in the Baltic Sea, as well as areas near New Zealand and Australia. More recently, scientists suspect a possible heatwave south of Greenland in the Labrador Sea. "We are having these huge marine heatwaves in different areas of the ocean unexpectedly evolve very early in the year, very strong and over large areas," says Karina von Schuckmann, an oceanographer at Mercator Ocean.

Carlo Buontempo, director of the European Union's Copernicus Climate Change Service, says scientists expect big temperature variations in the Pacific Ocean associated with the El Nino weather pattern, a phase of planet-warming weather which is just beginning, although NOAA is monitoring a large heatwave in the Gulf of Alaska that has been sitting offshore since late 2022. But what we're currently seeing in the North Atlantic is "truly unprecedented", says Buontempo. Scientists are still trying to unravel its full causes. [...] More broadly, experts say the persistence of recent marine heatwaves is a worrying sign about how climate change is unfolding, alongside heatwaves on land, unusual melting of snow cover in the Himalayas and a loss of sea ice. Von Schuckmann notes that, even if humans stopped pumping CO2 into the air tomorrow, the oceans would continue to warm up for many years yet. "I am concerned as a climate scientist that we are further than we thought we are."

      Yup. Picture yourself in a car, rolling down on a big descending slope. Chances are you will be accelerating, until you start hitting the brakes.

      Fun thing with climate change: hitting the brakes (reducing CO2 emissions) will start producing effect about 20 years after you hit the aforementioned brakes. In the meantime, you can scream all you want. Not hitting the brake is also an option though: you will just accelerate further, until you actually die and either bring everyone down with you, or someone more

    Why worry when I know Leo Di Caprio and lots more wealthy people are worrying for me? They are everywhere, with their private jets and yachts, looking for solutions to the hardest problems we ordinary people are suffering from!

    As a side note... I am on the market for a yacht... Nothing big, 36 meters to start with... What non-diesel model is best for me?

      You appear to be jumping from "There are these wealthy hypocrites" to "Therefore this is not a major concern." But the second does not follow from the first,
      • by dragisha ( 788 )

        You see, the biggest promoters of "climate science" are said "wealthy hypocrites". But, as recognized by people moderating this, I was being sarcastic there.

        On a serious note... The climate is changing, so some problem (for humans defying nature by living in places we did not inhabit in earlier times) exists. But is CO2 our problem? Are humanity's actions a problem? Are we sure there? Isn't CO2 basic food for plants and aren't we seeing our planet greener and greener, so more oxygen is produced as we speak?

        • Skepticism is important. But we in this context have absolutely overwhelming amounts of evidence that CO2 output is the major driver of climate change. And yes, some humans are living in places they did not live previously, or lived in much smaller numbers. But that is a problem with or without climate change. Climate change in making things worse in many places where humans have lived for thousands of years. That problem is real and needs to be dealt with.
    • Non-diesel? That's crazy talk. Gasoline is hygroscopic, it's one thing to use it on a lake where you can get a tow easily, and another thing entirely on the ocean.

    • Wonder who will be having the last laugh, cool as a cucumber in a non-AC cooled basement?

      We don't float down here, but we're quite cool, and you will all be joining us soon. -_-

      I think going underground should and will be more of a thing, though that's no excuse to continue being a bunch of polluting swine.

    Nation states have proven that they fail to handle problems which are trans-national.

    Even in principle, why should a kid born in a ghetto in Nairobi have far fewer opportunities in life than one born in an affluent suburb in California?

    For thousands of years, much of the world was run on empires. Then came nation states. They have now outlived their usefulness.

    There are not 195 countries. They are a mental fiction. A mass delusion. There is one planet.

    But human egos are programmed to be divisive. That's fine... for the first hundred thousand years, when we went from being tribes killing each other, to empires killing each other, to nation states killing each other. The groups got bigger. But a bigger group also means a bigger power game. Now we've run out of space. There's nowhere left to conquer.

    We need to return to understanding nature, and to understanding our own humanity.

    We must have a world government.

      The fundamental flaw in your thinking is that humans have somehow evolved and changed for the better. The problems we have right now with inefficient, corrupt, clown-circus governments will simply be translated to a global entity when we end up with a single world government.
      Technological progress outpaced us and, though we didnt change much from our nomad tribe days, we now have nuclear weapons and the god-like power of world destruction.
      We will return to understanding nature and our humanity eventually, when all else will fail us.

      • The fundamental flaw in your thinking is that humans have somehow evolved and changed for the better.

        Their thinking is based on the idea that humans have not changed. That's why we need unified government. Unfortunately such a thing is as dangerous as it is necessary. Humans are mostly too selfish for it to work.

          The EU works pretty well. Remember checks and balances? The EU has 27 countries holding each other accountable.

          If anything, it didn't give itself enough power to deal with the likes of Erdogan.

      Ask the countries of the former soviet union, britain, france etc how they felt about being part of an empire. Clearly you have little understanding of human nature and how local culture and nationality matters to people.

      Mitigating climate change doesn't require the clapped out communist utopia you're dreaming of and in fact all powerful government tends to give less of a shit than less powerful ones about giving the people what they need.

  • ... are we ready to go fully nuclear then?

    Or are we going to just keep hectoring and milking it for politics?

      Nuclear would be bad for the oil companies profits so they will keep financing opposition to it.

  • The predictability of these climate doom articles is inversely proportional to their failure to predict the climate. Fool me once, shame on you. Fool me twice, shame on me.

    • by Jeremi ( 14640 )

      You know who is really good at predicting future disasters? Insurance companies -- it's literally their job, in that if they can't predict problems accurately, they will either price premiums too low to cover their future payouts, and go bankrupt, or price them too high and get undercut by the competition, and go bankrupt.

      And guess what? Insurance companies increasingly think climate change is making many areas uninsurable, so they are leaving those markets [npr.org].

      • You'll note that there are far less pro-oil people posting outright denial. The parent post is getting harder to find, because it's so demonstrably false. Now what's more common is blaming China, with the inference that until China comes on board, we might as well just puke GHGs.

      • Insurance companies simply go by their experience. A lot of losses from hurricanes? Raise premiums or leave the market. A lot of losses from floods? Raise premiums or leave the market. A lot of losses from wildfires? Raise premiums or leave the market.

        They did NOT raise prices based on doom predictions; they raised prices based on experience. They don't care if these losses were ultimately due to climate change, natural cycles, or the wrath of god; they just care that they happened, so they have adjus
