As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years - from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8.
@freddermody Honesty is the best policy. Essentially, there is no strong connection between CO2, and ocean pH. The ocean is not acidic, and there is really no possibility of it becoming so.
So the coral reefs that are bleached and crumbling, along with mollusks whose shells are brittle and crumbling (or simply not even forming at all) have absolutely nothing to worry about is what you're saying?
@kittendkat5100 The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool - the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.
Our body is a good example. Our blood pH needs to stay within 0.05 pH of 7.40. So if our blood pH drops below 7.35 or goes above 7.45, we will first get very sick, and if our blood pH doesn't return to that very small range, we will die. Our blood is slightly alkaline (basic). Even though from 7.00 to 14.00, the pH is alkaline, that doesn't mean we can survive with our blood at, let's say, a pH of 8.00. It may seem like a small change, but that's because the pH scale is a logarithmic scale. The real numbers are very big and far apart so a logarithmic scale is used to condense the numbers to make it easier to read.
@@kevinheinrichs1073 To add on, osteoporosis is an example of sorts of "acidification" in the body. What osteoporosis does to human bones is what ocean acidification is doing sea life that form calcium matrices.
Sedimentary Geologist here… Ocean acidification is the most phenomenal fraud that is being used to scare a scientifically ignorant public. ‘acidification’ is a mere linguistic trick used because acids are scary to the general public. pH is measured in a logarithmic scale. The average pH of seawater is 8.1. To go from 8.1 to 7.0 (neutral) would require a 110 fold decrease in the amount of carbonate in the water. Whilst a decrease in pH from 8.1 to 8.0 technically equates to a numerical acidification, to call it acid is an outright lie as a pH of 8.0 is alkaline. Even if CO2 absorbed from the atmosphere didn’t off gas rapidly, there is so much dissolved carbonate in the earths oceans that it forms limestones beds several kilometres thick. The chemical buffering capacity of the earths oceans is essentially limitless with an inexhaustible supply of calcium (& magnesium) being supplied by the weathering of minerals at the earth’s surface. Acidification (and global warming in general) is a colossal fraud.
@aaronballey4823 that is so true they have all the facts to prove is your probably just a fake scientist that studies those diamond digging kits for kids
A clear explanation!
Just what I was looking for!
thank you for the video! helped me in school
Hello, great video, what programme did you use to create this? Thank you.
"may not be safe" that definatly sounds like an impending disaster.
helped me so much in school thanks
Why can't we extract hydrogen from seawater (& use it) to offset the ocean acidification process?
Where will the hydrogen go?

i have no idea what any of this means

excellent job 🤓🤓

So it's not actually happening then?
It is happening its just not becoming an acid. It's becoming more acidic so to speak but is still alkaline.
Our body is a good example. Our blood pH needs to stay within 0.05 pH of 7.40. So if our blood pH drops below 7.35 or goes above 7.45, we will first get very sick, and if our blood pH doesn't return to that very small range, we will die. Our blood is slightly alkaline (basic).

You can be a "sedimentary geologist" and still know jack shit about ocean and atmospheric chemistry.
