Ocean acidificationcannot possibly be reversed in a time scale relevant to civilization. This is a physical reality explained in many scentific articles. It cannot even be stopped even with a collapse in the economy. Numerous studies consider the deleterious impact of the acidification (and associated ocean warming) on the marine ecosystem, including coral reefs (such as the Great Barrier Reef off the Australian east coast).

So, you certainly have done your homework!

So, if cycles are correct, do we have Europe freezing but with oceans being more acid than previously? Do we then have a collapse in the economy which would stop further acidification (presumably)?

In looking at what you and other scientists have written on this page, the question of the Paris conference remains. If so much damage to such huge bodies of water has already been done (far bigger than Earth’s land masses) then how can this be reversed, even after it is stopped as noted above?

What good, therefore, is Paris besides a fine photo op?

Regardless if you are freezing or melting it is the acidification of the ocean which is the main issues!

The question I ask is:

If climate change is a natural cycle in the past, which includes sun max/min cycle.

Why didn’t the acidification of the ocean occur then?

I have laid out a few details below regarding the facts on acidification history as this will be the main driver for us to stop burning fuel!

The currently observed increase of CO₂ concentrations in the oceans is, in terms of its magnitude and rate, unparalleled in the evolutionary history of the past 20 million years.

**********************************************************************************

Ocean acidification has occurred previously in Earth's history. The most notable example is the Paleocene-Eocene Thermal Maximum (PETM),^[20] which occurred approximately 56 million years ago

https://en.wikipedia.org/wiki/Ocean_acidification

**********************************************************************************

For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.

On the pH scale, which runs from 0 to 14, solutions with low numbers are considered acidic and those with higher numbers are basic. Seven is neutral. Over the past 300 million years, ocean pH has been slightly basic, averaging about 8.2. Today, it is around 8.1, a drop of 0.1 pH units, representing a 25-percent increase in acidity over the past two centuries.

The oceans currently absorb about a third of human-created CO2 emissions, roughly 22 million tons a day. Projections based on these numbers show that by the end of this century, continued emissions could reduce ocean pH by another 0.5 units. Shell-forming animals including corals, oysters, shrimp, lobster, many planktonic organisms, and even some fish species could be gravely affected.

**********************************************************************************

Such a relatively quick change in ocean chemistry doesn’t give marine life, which evolved over millions of years in an ocean with a generally stable pH, much time to adapt. In fact, the shells of some animals are already dissolving in the more acidic seawater, and that’s just one way that acidification may affect ocean life. Overall, it's expected to have dramatic and mostly negative impacts on ocean ecosystems—although some species (especially those that live in estuaries) are finding ways to adapt to the changing conditions.

**********************************************************************************Is Methane escaping due to global warming?

There have been observations of bubbles emanating from the sea floor in the Arctic (Shakhova, 2010; Shakhova et al., 2005) and off Norway (Westbrook, 2009). The Norwegian bubble plume coincides with the edge of the hydrate stability zone, where a bit of warming could push the surface sediments from stable to unstable. A model of the hydrates (Reagan, 2009) produces a bubble plume similar to what’s observed, in response to the observed rate of ocean water warming over the past 30 years, but with this warming rate extrapolated further back in time over the past 100 years. The response time of their model is several centuries, so pre-loading the early warming like they did makes it difficult to even guess how much of the response they model could be attributed to human-induced climate change, even if we knew how much of the last 30 years of ocean warming in that location came from human activity.

Methane

Here’s the kicker: methane, the gas produced extensively by the livestock industry worldwide, traps up to 100 times more heat in the atmosphere than carbon dioxide within a 5 year period, and 72 times more within a 20 year period. The good news is that methane also leaves the atmosphere within a decade. This makes for a short-lived, but intense climate changer.

So methane warms the planet rapidly, but it dissipates from the atmosphere more quickly than carbon dioxide. According the EPA, the GWP of methane is 21, which indicates its effect over a 100 year period. A 2009 report published by The World Watch Institute stressed that the more relevant GWP figure is 72, since it’s within the next 20 years that we desperately need to act to stop climate change before a domino effect is initiated and our imbalanced bio-systems spiral out of livable conditions.

Runaway climate change or runaway global warming is hypothesized to follow a tipping point in the climate system, after accumulated climate change initiates a reinforcing positive feedback.

Temperature record

Geologic evidence of past temperature changes

On longer time scales, sediment cores show that the cycles of glacials and interglacials are part of a deepening phase within a prolonged ice age that began with the glaciation of Antarctica approximately 40 million years ago. This deepening phase, and the accompanying cycles, largely began approximately 3 million years ago with the growth of continental ice sheets in the Northern Hemisphere. Gradual changes in Earth's climate of this kind have been frequent during the Earth's 4500 million year existence and most often are attributed to changes in the configuration of continents and ocean sea ways.

Five million years of climate change.
